Audio System with Navigation: Other Saab 9-5 II

Speech recognition

The speech recognition enables the operation of some cellular telephone functions by voice input. It recognizes commands and sequences of numbers independently of the person speaking. The commands and sequences of numbers can be spoken without a break between the individual words. It is also possible to save telephone numbers using a name randomly chosen by the user. The telephone connection can be created using the proper name.

Navigation System Components

The navigation system contains the following components

1. Navigation Radio
2. Global Positioning System (GPS) Antenna
3. Auxiliary RCA video jacks (If equipped)

Navigation Radio

This component acts as the operator interface for the navigation system, provides the data input from the operator to the navigation system and provides navigation information to the operator via the display screen. The navigation radio is located in the center of the instrument panel. The navigation radio provides the following

1. A display screen - All navigation, audio and TV functions are displayed on this screen.
2. Soft key buttons on the display to allow selection from menus and to operate the navigation system and the audio system.
3. The DVD provides map data for navigation and map route guidance.
4. The navigation system map with routing information displayed on the navigation radio screen.
5. Provides verbal guidance to the operator.
6. Connection to the global positioning system (GPS) antenna, which provides the vehicle position information.

Global Positioning System (GPS) Antenna

The global positioning system (GPS) antenna is located on the roof of the vehicle and is connected to the navigation radio by a coaxial cable. The antenna is used to collect the signals of the orbiting GPS satellites, and is powered through the same coaxial cable used to send the signals to the radio.

Some vehicles may employ a signal splitter in the GPS antenna coaxial cable. The signal splitter allows another device that requires the GPS signals to be connected to the antenna along with the navigation radio. The signal splitter divides the navigation antenna signal into two paths without any transmission loss.

Route Guidance

The map will display the route to the selected destination. Voice prompts alert the operator of upcoming events (turns) and arrivals at the destination. The navigation system will automatically recalculate if the route is not followed. The navigation radio uses data received from the global positioning system (GPS) satellites as well as the vehicle speed signal to accurately display the current position of the vehicle. The map DVD must be in the navigation radio for route guidance.

The navigation system voice recognition allows for hands-free operation of navigation and audio system features. The voice recognition can be used when the ignition is in accessory or ON, or when retained accessory power is active. This feature only works if the map DVD is inserted and the AGREE button has been pressed.

Points of Interest

Points of interests are locations that are frequently visited. Points of interest can be can be displayed on the map or set as a destination. The following are some of the available Points of interests

1. Gas Station
2. Restaurant
3. College
4. Police Station

Telematics Communication Interface Module

The telematics communication interface module is a cellular device that allows the user to communicate data and voice signals over the national cellular network. Power is provided by a dedicated, fused B+ circuit. Ground is provided through the vehicle wiring harness attached to the module. The ignition state is determined by the telematics communication interface module through serial data messaging.

Special circuits for connecting the Telematic module for communication interface to a microphone, the button unit, and to affect the status light-emitting diode. The Telematic module for communication interface communicates with the rest of the car via the serial data bus.

The module houses 2 technology systems, one to process GPS data, and another for cellular information. The cellular system connects the OnStar® system to the cellular carrier's communication system by interacting with the national cellular infrastructure. The module sends and receives all cellular communications over the cellular antenna and cellular antenna coax. GPS satellites orbiting earth are constantly transmitting signals of their current location. The OnStar® system uses the GPS signals to provide location on demand.

The module also has the capability of activating the horn, initiating door lock/unlock, slowing down stolen vehicle gradually, or activating the exterior lamps using the serial data circuits. These functions can be commanded by the OnStar® Call Center per a customer request.

Secondary OnStar® Controls

Some vehicles may have an additional button that when pushed can engage the OnStar® system. The button may be a symbol of a face with sound waves, or may say MUTE, or be a symbol of a radio speaker with a slash through it.

By engaging the OnStar® system with this feature, the user can interact with the system by use of voice commands. A complete list of these commands is supplied in the information provided to the customer. If the information is not available for reference, at any command prompt the user can say "HELP" and the telematics communication interface module will return an audible list of available commands.

OnStar® Microphone

The OnStar®, or cellular phone microphone, can be a part of the rearview mirror assembly, or on some vehicle lines, a separate, stand alone unit. In either case, the telematics communication interface module supplies approximately 10 V to the microphone on the cellular phone microphone signal circuit, and voice data from the user is sent back to the telematics communication interface module over the same circuit. A cellular phone microphone low reference circuit or a drain wire provides a ground for the microphone.

Cellular and GPS Antennas

This vehicle will be equipped with one of the following types of antennas

1. Separate, standalone cellular and navigation antennas
2. A combination cellular and navigation antenna, which brings the functions of both into a single part
3. A cellular, GPS, and digital radio receiver antenna, which also incorporates the functionality of the digital radio receiver satellite antenna (XM).
4. A cellular, GPS, and digital radio receiver antenna, which also incorporates the AM/FM antenna.

The cellular antenna is the component that allows the OnStar® system to send and receive data over airwaves by means of cellular technology. The antenna is connected at the base to a coax cable that plugs directly into the telematics communication interface module.

The GPS antenna is used to collect the signals of the orbiting GPS satellites. Within the antenna is housed a low noise amplifier that allows for a more broad and precise reception of this data. The antenna is connected at the base to a coax cable that plugs directly into the telematics communication interface module. The cable also provides a path for DC current for powering the antenna.

The OnStar® Call Center also has the capability of communicating with the vehicle during an OnStar® call to retrieve the latest GPS location and transmit it to the OnStar® Call Center. A history location of the last recorded position of the vehicle is stored in the module and marked as aged, for as long as the module power is not removed. Actual GPS location may take up to 10 minutes to register in the event of a loss of power.

Cellular and Navigation Signal Antenna Splitter

The navigation signal splitter is a component for dividing the navigation signal antenna signal into two paths without any transmission loss. It has two RF-connectors, one signal fakra connector and one double fakra connector. Port 1 is the input for connecting to the navigation signal antenna, port 2 is the output for the car OnStar navigation system, port 3 is the output for the navigation radio. Port 1 and 2 are galvanically coupled internally using a matching network. The OnStar system supplies the navigation signal antenna with power via port 2. Connectivity is made between port 1 and 3 though and internal coupling element and low noise amplifier. The navigation radio provides the amplifier with power via port 3.

Bluetooth ® (If Equipped)

Bluetooth ® wireless technology is a short-range communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. Only vehicles with steering wheel controls will have Bluetooth ® functionality. In order to utilize the vehicle Bluetooth ® system, a Bluetooth ® equipped cellular phone is required.

The Bluetooth ® antenna is a small fixed antenna connected directly to the telematics communication interface module and is used to send and receive signals from a Bluetooth ® enabled cellular phone. The antenna utilizes no cabling and is not external to the vehicle. The available features and functions are determined by the software within the device being used and the telematics communication interface module. The operating range of the signal from the vehicle is approximately 30 feet. Note that the operating range is dependent upon the cellular phone being used and battery level of the phone.

With Bluetooth ® technology customers can experience hands-free calling as their Bluetooth ® capable cellular phones are wirelessly connected to the vehicle. It will allow customers to place and receive calls using the steering wheel controls and voice recognition. The vehicle audio system will allow you to listen to your call through the vehicle speakers and adjust volume through steering wheel or radio controls.

Not all Bluetooth ® cellular phones are guaranteed to work with the vehicle's Bluetooth ® system. Based on the cellular phone's service provider and the manufacturer's implementation of Bluetooth ®, not all phones support all available Bluetooth ® functionality.

Bluetooth ® Features Supported

The following is a list of features supported by the Bluetooth ® system. Note that not all devices will support all of the listed functions.

1. Automatic reconnection - highest priority phone will automatically be connected to vehicle when vehicle ignition is on
2. Hands-free dialing-via digits, redial, name tags (phone number saved to a nametag via voice recognition)
3. Answering a call
4. Ending a call
5. Mute a Call
6. Rejecting a call - ignore an incoming call
7. Call Waiting
8. Three-way Calling - initiated from hands-free system
9. Send Number During a Call - this is used when calling a menu-driven phone system
10. Transfer a Call - transfer call from vehicle to cellular phone and visa versa
11. Voice Pass-Thru - allow access to the voice recognition commands on the cellular phone

Pairing a Bluetooth ® Cellular Phone to the Vehicle

In order to use hands-free calling, the cellular phone must be paired to the vehicle. Up to five devices can be paired to the vehicle at one time, but only one can be connected at any given time. To pair a phone, the customer must know how to operate the Bluetooth ® functionality of their phone. The pairing process must only be done one time for each phone, unless that phone's information is deleted. For safety reasons, the pairing process is disabled while the vehicle is moving.

Once the Bluetooth ® cellular phone has been paired with vehicle, it will automatically connect to the vehicle when the ignition is on and the device is on. When more than one paired phone is in the vehicle, the phone with the highest priority will be connected. If the cellular phone is in use while getting into the vehicle, the phone can be switched to hands-free mode with the press of a button. In addition, a call in progress can be transferred from the vehicle hands-free mode to the phone to continue the call as the customer exits the vehicle.

Complete pairing instructions are provided in the Vehicle Owners Manual.

Back Up Battery (If Equipped)

Note. Do not disconnect the main vehicle battery or remove the telematics communication interface control module fuse with the ignition in any position other than OFF. Disconnecting power to the telematics communication interface control module in any way while the ignition is ON or with retained accessory power activated may cause activation of the OnStar® Back-Up Battery. This action is per design as the back-up battery is designed to provide power to the telematics communication interface module so an emergency notification call can be made after a vehicle collision where the main battery is disabled. Once the Back-Up Battery is activated it will stay on until it has completely discharged. The back-up battery is not rechargeable and once activated the back-up battery must be replaced.

Certain OnStar® equipped vehicles may also be equipped with a back-up battery. The back-up battery is a non-rechargeable, lithium battery intended to provide an auxiliary power source for the telematics communication interface module in the event of a vehicle collision where power from the main vehicle battery is lost.

The back-up battery is intended to have a limited life span of approximately 4 years and is designed to maintain an open circuit voltage between 16V and 9V throughout this period. This allows the battery to power the basic functions of the telematics communication interface module for least one 200 second (5 minute) call at the end of the 4 year span, should a main vehicle battery loss collision occur.

The back-up battery is connected to the telematics communication interface module through the back-up battery positive voltage circuit and back-up battery ground circuit and is protected from a short circuit by means of an internal fuse. In the event the back-up battery positive voltage circuit is shorted to the back-up battery ground circuit or chassis ground, the fuse will open and render the back-up battery permanently inoperable. The status of the back-up battery and its associated wiring is monitored by the telematics communication interface module.

Audio System Interface

When the OnStar® requires audio output, a serial data message is sent to the audio system to mute all radio functions and transmit OnStar® originated audio. The OnStar® audio is transmitted to the vehicle audio system by a dedicated signal circuit and a low reference circuit.

The audio system will mute and an audible ring will be heard though the speakers if the vehicle receives a call with the radio ON.

On some vehicles, the HVAC blower speed may be reduced when the OnStar® system is active to aid in reducing interior noise. When the system is no longer active, the blower speed will return to its previous setting.

OnStar® Sleep Cycle

The OnStar® system uses a unique sleep cycle to allow the system to receive cellular calls while the ignition is in the OFF position and retained accessory power mode has ended. This cycle enables the telematics communication interface module to perform remote functions, such as door unlock, as commanded over the air by the OnStar® Call Center, and to continue to maintain an acceptable level of battery electrical drain.

The OnStar® system uses 4 states of readiness, depending upon the type of cellular market the vehicle is in when the ignition is put into the OFF state

1. High power
2. Low power
3. Sleep
4. Digital standby

The high power state is in effect whenever the ignition is in the ON or RUN position, or retained accessory power is enabled, and the OnStar® system is sending or receiving calls or when the system is performing a remote function.

The low power state is in effect when the OnStar® system is idle with the ignition in the ON or RUN position, or with retained accessory power enabled.

The sleep state is entered after the vehicle has been shut off and the retained accessory power has timed out while in an analog cellular area. At a predetermined time recorded within the telematics communication interface module, the system re-enters the low power state to listen for a call from the OnStar® Call Center for 1 minute. After this interval, the system will again return to the sleep state for 9 minutes. If a call is sent during the 1 minute interval, the OnStar® system will receive the call and immediately go into the high power mode to perform any requested functions. If no call is received during the 1 minute interval, the system will go back into the sleep mode for another 9 minutes. This process will continue for up to 48 hours, after which the OnStar® system will turn off until the ignition is turned to the ON or RUN position.

The digital standby power state is entered after the vehicle has been shut off and the retained accessory power has timed out while in a digital cellular area. When in digital standby mode, the OnStar® module is able to perform all remote functions as commanded by an OnStar® advisor at any time, for a continuous 48 hours. After 48 hours, the OnStar® module will go into sleep mode until a wake up signal from the vehicle is seen by the telematics communication interface module. If the OnStar module loses the digital cellular signal it will revert to analog mode and follow the standard sleep state (9 minutes OFF, 1 minute standby) based on the time of the GPS signals, this will continue until a digital cellular signal is again received.

If the OnStar® system loses battery power while the system is in a standby or sleep mode, the system will remain OFF until battery power is restored and the ignition is turned to the ON or RUN position.

OnStar® Personal Calling

The hands free, OnStar® personal calling cellular phone feature is an additional feature of the OnStar® system. This feature is embedded within the telematics communication interface module; however it must be activated by an OnStar® advisor. OnStar® personal calling operates similar to most hand held cellular phones in that the availability for its usage is based on minutes or units. The customer must have a current OnStar® subscription, as this feature cannot be utilized without it. To use OnStar® personal calling, the customer must also purchase units (minutes) as outlined in the owners guide provided with the OnStar® system. Units begin to deplete, 1 unit is equal to 1 minute, as the customer makes outbound phone calls, answers inbound phone calls, or while connected to the OnStar® virtual advisor. In addition, units may also have an expiration date, depending upon the type of units purchased.

Customers have the ability to store telephone numbers within the module, referenced by a nametag for the convenience of frequently dialed numbers. After storing a nametag, the user can dial this number by initiating the OnStar® personal calling feature, speaking the word "call," and repeating the nametag assigned.

Customers have the capability to lock their OnStar® personal calling system by pressing the answer/end call button, speaking "security" and entering a 4-digit code. Once this process is complete, the user must enter the code before OnStar® personal calling is available. In the event the customer cannot remember their code and is unable to use their system, they can press the blue OnStar® button and speak to an advisor to unlock the system by means of a discrete cellular call to the vehicle.

Turn by Turn Navigation

Turn by Turn Navigation allows the driver to contact OnStar® to obtain directions for driving from a current location to a desired location. The system for Turn by Turn Navigation stores your planned route and continuously follows up your position along the route. If you deviate from the planned route, the system detects this and gives verbal messages about how the trip should continue. The driver then responds verbally to direct the system to continue the current routing or to recalculate the route because of a missed turn. On some vehicles, the Turn by Turn Navigation instructions may be displayed to the driver in the radio display or the driver information center.

OnStar® Stolen Vehicle Slowdown (If equipped)

OnStar® Stolen Vehicle Slowdown allows advisors working with law enforcement services to send a signal to limit fuel flow to the engine, gradually slowing down the stolen vehicle.

Stolen Vehicle Slowdown is an enhancement to OnStar's Stolen vehicle Location Assistance, which uses GPS technology to pinpoint the location of a vehicle reported stolen. Stolen Vehicle Slowdown is powered by OnStar's new generation of hardware (Generation 8).

Advisor Record Feature

The Advisor Record Feature allows the user to store any information given during a call with an OnStar® Advisor. Recording is activated by pressing the blue OnStar button during a call; pressing the button a second time stops the recording. The stored information can be played back by pressing the phone button and using the voice command "Advisor Playback".

Deactivated OnStar® Accounts

In the event a customer has not renewed their OnStar® account after expiration or the account was never activated, OnStar® will make a discrete cellular call to the vehicle to deactivate the OnStar® system. Before taking this action, customers are notified that the OnStar® system in their vehicle will be deactivated unless they elect to renew the account. After the OnStar® account has been deactivated, customers will experience the following

1. The OnStar® status LED will not illuminate.
2. The OnStar® system will NOT attempt to connect to the OnStar® Call Center in the event of a collision or if the vehicle front air bags deploy for any other reason.
3. An emergency button press will play a demo message indicating the service has been deactivated.
4. An OnStar® Call Center button press will connect the customer with a dedicated sales team who can sell an OnStar® subscription and reactivate the vehicle. Depending on the type of OnStar® hardware in the vehicle, the customer may first hear a demonstration message stating there is no current OnStar® subscription for the vehicle, and directing the customer what to do to activate services.
5. OnStar® personal calling will not be available, as this feature requires the customer to have a current OnStar® account. Attempts to use this feature may result in cellular connection failure messages and the inability to connect to the number dialed.

Certain vehicles that have never had an active OnStar® account, or that have been deactivated, may be unable to establish a connection with the OnStar® Call Center. When normal published diagnostic procedures do not indicate a possible cause for the no connect concern, the vehicle may have been deactivated. For deactivated vehicles, a no connect response should be considered normal operation. Further diagnosis and subsequent repair is only necessary should the customer elect to become an active OnStar® subscriber or renew the account subscription.

General Tips for Better Speech Recognition

Radio Power

The radio is supplied power by a fused B+ circuit. The radio does not use a discrete ignition feed circuit for power moding. The power mode master provides the system power mode to the radio via serial data messages. The power mode master determines the system power mode by processing power mode information from ignition switch inputs. Power modes supported by the radio are OFF, ACCESSORY, RUN, and CRANK REQUEST.

Radio Grounds

The vehicle harness provides a ground for the radio circuits. The radio may also be case grounded.

Radio Data Link Communication

The radio communicates with other modules via serial data.

Radio Outputs

At minimum volume, the plus (+) and minus (-) speaker outputs are approximately half battery voltage, measured to vehicle ground. As the volume increases, the plus and minus change to create a voltage difference between each other either driving the voice coil of the speaker, or being fed to an amplifier.

Radio Head Dimming

Dimming and backlighting levels are determined by the serial data messages the radio receives.

Radio/HVAC Controls

The radio/HVAC controls is a separate component from the radio. The radio/HVAC controls contain the radio control knobs and buttons for all audio functions. Additionally the radio/HVAC controls contain the radio information display.

The radio/HVAC controls operate radio functions through serial data messages.

When equipped with the optional navigation radio, the radio/HVAC controls communicate directly to the navigation radio, and the display communicates information through the signal circuits to the navigation radio.

When the operator rotates a radio control knob to change radio stations or increase the volume a message is sent to the radio over serial data. After receiving the message the radio will make the adjustment. Messages communicated between the radio and the radio/HVAC controls and info display include the following

1. Button presses/knob rotations
2. Info display module dimming
3. Radio/HVAC controls backlighting
4. Graphics and text information

HVAC data for controls and status indicators is communicated between the radio/HVAC controls and the HVAC control module with a separate Local Interconnect Network (LIN) serial data circuit. HVAC status screen information from the HVAC control module is transmitted to the radio on the GMLAN serial data circuit. The radio then displays the desired screen information on the info display.

Antenna System

Note. Radio systems with the antenna(s) in the glass are subject to possible interference when an aftermarket window tint is applied.

Multi-Band Antenna (If equipped)

The multi-band antenna is located on the roof of the vehicle. This type of antenna may be used with the AM/FM radio, but is primarily for OnStar® and the Satellite Radio (XM)™ Service System, if the vehicle has these features. Keep this antenna clear of snow and ice build up for clear reception. If the vehicle has a sunroof, the performance of the system may be affected if the sunroof is open. Loading items onto the roof of the vehicle can interfere with the performance of the system, ensure the multi-band antenna is not obstructed.

Diversity Antenna (If equipped)

The diversity antenna system may use both the back window antenna and an antenna internal to the antenna module. Any damage to the rear antenna requires replacing the glass. This system is designed to deliver the best radio signal reception possible. Two antennas are used to form a diversity system. The primary antenna is part of the rear window and looks similar to the defogger grid. This antenna receives both AM and FM signals. The secondary antenna is part of the antenna module.

The antenna reception signals are sorted out by the radio antenna module. The radio antenna module is enabled when the radio is turned on. Superimposed on the powered antenna coax is the strength of the signal being received by the antenna module. The antenna module switches between the antennas, monitoring the radio signal strength and combines the signals and phase aligns them to create one strong signal.

Radio Signal

The radio signal is sent from a broadcast station and is then received by an antenna. The strength of the signal received depends on the following

1. The power output (wattage) of the broadcasting station
2. The location of the vehicle (or receiver) relative to the broadcast tower.
3. Obstacles between the tower and the receiver
4. Atmospheric conditions
5. What band (AM or FM) the station is broadcasting
6. Type of antenna and the ground plane

AM Reception

The AM band has a lower frequency range than the FM band. These longer wavelengths

1. Bend around Obstacles
2. Follow the curvature of the earth
3. May reflect off the ionosphere (skip)

The AM frequencies have longer range due to the ground wave. The ground wave follows the curvature of the earth and is effected by its conductivity. Greater conductivity equates to less signal loss thus transmission over water is better than over land. The AM band has a range of 80-320 km (50-200 mi).

FM Reception

The shorter wavelengths of the higher frequency FM band

1. Reflect off obstacles
2. Are absorbed by the ground
3. Penetrate the ionosphere

Broadcasts in the FM band are limited to line of sight reception which is typically 40 km (25 mi). Even when out of a direct line of sight, the signal may be reflected into areas that would be in a shadow otherwise. Factors which affect the line of sight include

1. Height of the broadcast antenna
2. Height of the receiving antenna
3. Terrain and buildings in the broadcast path

Digital Audio Broadcast (if equipped)

The Digital Radio Broadcast is emitted terrestrial repeaters. A service fee may be required in order to receive the Digital Audio Broadcast service.

The Digital Audio Broadcast receiver is external to the Radio.

Amplifier Interface

A fused battery voltage circuit provides the main amplifier power. A switched 12 V output from the radio is used to control the power state of the amplifier. To respond quickly to audio input and control signals, the amplifier is ON in all vehicle power modes except OFF and CRANK Request. The internal amplifier bridges are fully powered and unmuted when the amplifier receives the switched 12 V input. This type of amplifier does not have serial data communication capability, and can not set DTCs.

Radio Data System (RDS) (If Equipped)

The radio may be equipped with RDS (Radio Data System). The RDS function is only available on FM stations transmitting RDS information. This system relies upon receiving specific information from these stations and only works when the information is available.

While the radio is tuned to an FM RDS station, the station name or call letters display.

RDS data is carried in what is known as a "subcarrier". A subcarrier is a frequency that the FM broadcaster is authorized to use to send data that is not audible in the main audio program.

1. RDS functions will only work with FM broadcast stations that are broadcasting RDS data.
2. Not all FM Broadcast stations broadcast RDS data or offer all of the RDS services.
3. The information displayed is dependent upon the information broadcast by the particular station. The information may vary greatly between stations.
4. RDS functions may not work properly when reception is weak, reception is of poor quality, or RDS is not implemented properly by the FM Broadcaster.
5. In some cases, a radio station broadcasting incorrect information may cause the RDS features of the radio to appear to work improperly.

With RDS, the radio can do the following

1. Seek to stations broadcasting the selected type of programming
2. Receive announcements concerning local and national emergencies
3. Display messages from radio stations

RDS may display text information such as

1. The name of the station.
2. The type of program.
3. General information such as artist and song title, call in phone numbers, etc.

RDS Messages

1. ALERT!: Alert warns of local or national emergencies. When an alert announcement comes on the current radio station, ALERT! displays. You will hear the announcement, even if the volume is low or a CD is playing. If a CD is playing, play stops during the announcement. Alert announcements cannot be turned off. ALERT! is not affected by tests of the emergency broadcast system. This feature is not supported by all RDS stations.
2. INFO (Information): If the current station has a message, the information symbol or INFO displays. Press this button to see the message. The message can display the artist, song title, call in phone numbers, etc. If the entire message can not be displayed, parts of the message appear every three seconds. To scroll through the message, press and release the INFO button. A new group of words displays after every press of this button. Once the complete message has displayed, the information symbol or INFO disappears from the display until another new message is received. The last message is displayed by pressing the INFO button. View the last message until a new message is received or you tune to a different station.

MP3/CD Formatting Information for MP3/CD Radios

The MP3/CD equipped radios will play standard audio CDs, and MP3/WMA files that were recorded on a CD-R or CD-RW disc. Customers who record their own music CDs should be aware of the following

1. The radio will only play audio from a CD-R/RW, it cannot record audio.
2. Standard audio and MP3/WMA files should not be mixed on a disc.
3. Song title, artist name, and album can display when files are recorded using ID3 tags version 1 and 2.
4. Long file, folder, or playlist names, or a combination of a large number of files and folders, or playlists can cause the player to be unable to play up to the maximum number of files, folders, playlists, or sessions.
5. The radio supports multi-session discs, but only the files from the last session will be played.

Integral Multi Disc CD Changer (If Equipped)

The integral multi disc CD changer has the capability of storing and playing up to six compact discs. The integral multi disc CD changer has a shock absorbing system. Only under extreme operating temperatures or severe shock or vibration should the compact disc player skip or mute. If the customer travels an abnormally rough road, a skip condition may be normal. Test drive the car on a normal road with a good CD disc. If the problem remains, replace the radio. The use of CD lens cleaner discs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD mechanism.

The CD mechanism within the radio will begin an initialization routine after a battery connect (e.g., connecting radio connector X1). The initialization process takes approximately 25 seconds to complete. It is very critical that the initialization is completed before removing battery power from the radio, in order for the complex moving parts of the CD mechanism to be positioned properly before shipping and/or handling purposes. Damage may result to the moving parts of the CD mechanism if battery power is removed during the initialization routine. The damage occurs to the CD mechanism during subsequent shipping or handling operations. The extent of the damage causes the CD mechanism not to recover and the mechanism becomes inoperative.

Rear Seat Audio (RSA) (if equipped)

The rear seat audio (RSA) feature allows rear seat passengers to listen to a different audio program than the front seat passengers. When RSA is ON, the rear vehicle speakers are muted, and the rear passengers can select their own audio program to listen to using the headphones.

The rear seat passengers can only control the sources that are not being listened by the front seat passengers. For example, rear seat passengers can listen to and control CDs or DVDs through the headphones while the driver listens to the radio through the front speakers. The front seat audio controls always have priority over the RSA controls. If the front seat passengers switch the source for the main radio to a remote source, the RSA is not able to control the source. The rear seat audio can be operated while the main radio is OFF, and the key is RUN, ACCESSORY, or when retained accessory power is active. The rear seat passengers have control of the volume for each set of individual headphones.

Depending on the audio system, the rear speakers may continue to play when the RSA is active through the headphones.

Theft Deterrent

The radio theft deterrent system is intended to disable radio functionality if incorrect vehicle information is received by the radio. The radio disables functionality if the vehicle identification number (VIN) sequence received by the radio (A VIN sequence is usually the last six digits of the VIN.) does not match the VIN information learned by the radio. The radio receives this information in a serial data frame form.

The radio provides the following theft operating modes as part of the radio theft deterrent system

1. No VIN Mode - A radio that has not received or learned a VIN. In this mode the radio has limited functionality.
2. Normal Mode - A radio has received a VIN sequence. The radio only adopts the VIN sequence if it contained all six figures. In this mode all radio functions are operative.
3. Theft Detected Mode - A radio that had previously learned a VIN sequence and subsequently received a VIN sequence not matching the learned sequence. In this mode the radio has limited functionality.

Radio Error Messages

The Radio may display the following Error Messages (Not all messages may be applicable)

1. ERR: This message is displayed when the radio is unable to play the inserted cassette or CD
2. LOC: This message is displayed when the radio has entered Theft mode.
3. CAL/CAL ERR: This message is displayed when the radio has detected an invalid calibration.
4. CDX ERR: Displays if communication is lost with the remote CD changer.
5. CHECK CD: Displays when the player encounters a focus or tracking error.
6. CHK CDX: Displays when the CD changer encounters a focus or tracking error.
7. DOOR OPEN: Displays when the CD changer door has been left open.
8. NO DISC: Displays when the radio expected a disc to be inserted.
9. NONE: Displays when the radio is unable to detect the vehicle speed data information via the serial data circuit.

If an error message is displayed, perform the appropriate diagnostics.

OnStar ® (If equipped)

When OnStar is activated, a serial data message is sent to the radio that activates a software program. When the software begins its process, the fade goes to the front, Bass and Treble are set to the mid range, the outputs are mono, and the audio source is OnStar. OnStar takes priority over any other audio source. All of these actions are preset values stored in the radio.

Universal Handsfree Phone (If Equipped)

When the universal hands-free phone is activated, a serial data message is sent to the radio that activates a software program. When the software begins its process, the fade goes to the front, Bass and Treble are set to the mid range, the outputs are mono, and the audio source is the universal hands-free phone. The phone takes priority over any other audio source. All of these actions are preset values stored in the radio.

Seatback Display System Components

Scheme 32

1. Two video display screens
2. Infrared Module (located only in the left screen) Driver side transmits and receives Passenger side only receives
3. Two sets of wireless infrared headphones
4. A remote control
5. Local video input for each Seatback Display for playing a video auxiliary device on the Seatback Display.

1. Left Driver Seatback Display
2. Left IR-Dimly Illuminates 8 Leds, Transmits Audio And Recieves Remote Signal
3. Right Passenger Seatback Display
4. Right IR-LEDS Do Not Illuminate, Receives Remote Signal Only
5. Local video input

Video Screen

The video screens are located in the back of the driver and front passenger seats. The rear Seatback Display screen shows video from the radio DVD player, or an AUX input device, such as a video game console or camera. Only the display console to the left has IR-transmitters for wireless headphones, this can be seen as 8 activated light-emitting diodes. These 8 light-emitting diodes are not visible on the video screen to the right. Both consoles contain an infrared receiver for the remote control. They are located in the middle of each of the Seatback Display console.

IR Module

Eight infrared light emitting diode (LED) transmitters are used to send audio signals to the wireless headphones that are included in the system. These LEDs are located on the driver side Seatback Display, and aimed to provide signal to any rear seating position. During operation, the LEDs may be visible through the lens on the driver side display, but not on the passenger side. This is normal operation; the illuminated LEDs are located on the driver side Seatback Display only.

Remote Control

To use the remote control, aim it at the transmitter window at either the right or left seatback consoles and press the button. Direct sunlight or very bright light may affect the ability of the entertainment system to receive signals from the remote control. If the remote control does not seem to be working, the batteries may need to be replaced. Objects blocking the line of sight may affect the function of the remote control.

If a CD, DVD, or MP3 disc is in the radio DVD slot, the remote control button can be used to turn on the video screen display and start the disc. The radio can also turn on the video screen display.

If the remote control is to be stored for a long period of time, remove the batteries and keep them in a cool, dry place. Do not store the remote control in heat or direct sunlight. This could damage the remote control. Keep the remote control stored in a cool, dry place.

Wireless Headphones

Wireless headphones allow for rear seat passengers to use the display DVD without disturbing the listening of front seat passengers. The wireless headphones receive audio signals from the infrared (IR) transmitter on the left Seatback Display. This transmission is line of sight only, so audio quality will be degraded if anything blocks the transmitter signal from reaching the headphones, or if the headphones are placed in the front of the vehicle. The infrared transmitter located on the left Seatback Display will have red LEDs dimly illuminated when activated.

The wireless headphones include 2 channels. This allows rear seat passengers to utilize both screens individually without disturbing one another. On some wireless headphone models, you will see a red LED illuminated when the headphone is turned ON.

Each set of headphones has a rotary volume control. To adjust the volume, adjust this control. The headphones may automatically turn OFF if they lose the infrared signal from the system for approximately 4 minutes in order to preserve their battery power. The signal may be lost if the system is turned off or if the headphones are out of range of the infrared signal transmitters that are located near the video display screen.

Wireless Headphones without Rear Seat Audio (RSA)

The wireless headphones setup on the Seatback Display system without Rear Seat Audio (RSA) is unique. If the RSA system is not included with vehicle, the audio that can be heard on the wireless headphone channel 2 will only be from a device (IPOD, MP3 player, game system, etc.) that is connected to the rear seat auxiliary audio jacks. Wireless headphone channel 1 will provide audio from any disc in the DVD player, including DVD audio, CD audio, and MP3 or WMA audio discs.

Video Inputs

The local video input is the standard yellow RCA color-coded jacks. The RCA jack is located on the front lower side of the Seatback Display housing. Any composite video signal (from a video game, camera, stand-alone DVD player, etc.) attached to this input will override the video from the vehicle DVD or rear auxiliary jack. Power for auxiliary devices is not supplied by the radio system. To use the video input of the rear seat entertainment system, connect the auxiliary device cables to the video jacks and power ON both the auxiliary devices and the Seatback Display screen. Any use of this input will have to access audio from the external device only.

The RSA is integrated into the rear HVAC control module. Audio, video source are controlled by the radio through serial data communication. Some sources are: Radio, CD, and if the vehicle has these features, DVD, front auxiliary, and rear auxiliary.

The rear speaker channels pass through the RSA. The rear seat audio can be muted by the RSA when in use.

OnStar Steering Wheel Control Functions Malfunction

Some vehicles equipped with the OnStar® system have the capability of accessing voice mailboxes and other automated phone systems by means of the steering wheel controls, while the OnStar® Personal Calling feature is in use. If the "Talk" or "Mute" button (depending upon the vehicle) on the steering wheel controls is depressed during an OnStar® Personal Calling call, the telematics communication interface control module receives the message on the serial data bus from either the radio or body control module. This message is interpreted as a request to turn any spoken numbers into dual tone multi-frequency tones to be delivered over the airwaves to the phone system the user is communicating with. Complete instructions for operation of these features can be found in the information provided to the customer with the OnStar® system.

The steering wheel controls are a resistor network that consist of multiple momentary contact switches and a series of resistors. The switches and resistor network are arranged so that each switch has a different resistance value. When a switch is pressed, a voltage drop occurs in the resistor network, which produces a specific voltage value unique to the switch selected, to be interpreted by either the radio or BCM. In the event the OnStar® steering wheel control functions are inoperative, technicians should refer to STEERING WHEEL CONTROLS MALFUNCTION , to begin diagnosis of the steering wheel control concern.
