General Operation

Refer to the Navigation Manual for the navigation system operating procedures.

Anti-Theft Feature

The navigation system has a coded theft protection circuit. Make sure you have the anti-theft security code before

1. Disconnecting the battery.
2. Disconnecting the audio-navigation unit connector A (24P).
3. Removing the No. 15 (10 A) fuse from the under-hood fuse/relay box.

After service, reconnect power to the audio-navigation unit, and turn the ignition switch to ON (II). Enter the 5-digit anti-theft security code.

If the code card is lost or unavailable, you can get the code from the iN using the navigation system serial number. The system serial number can easily be obtained without removing the audio-navigation unit.

To get the serial number and the code, do this

1. Press and hold the MENU, MAP/GUIDE, and CANCEL buttons at the same time.
2. At the select diagnosis items screen, select Detail Information & Setting, select Unit Check, then ECU Info. The system runs a brief diagnosis, then the audio-navigation unit serial number is displayed at the bottom of the screen.
3. Use the Anti-theft code inquiry option on the iN to look up the 5-digit anti-theft code. The iN may display more than one code for a given serial number. This is because serial numbers are not unique. You may have to try more than one 5-digit code. If no code is shown, or if the code(s) given do not work in the audio-navigation unit, contact the Automobile Warranty department.

Alternatively, you can find the serial number on the upper label which is located on the audio-navigation unit in the dash.

The HDD and audio-navigation unit are mated to each other and can only be mated to a new unit. If someone tried to put a stolen HDD in another audio-navigation unit, or insert their HDD in a stolen audio-navigation unit, the two components cannot mate and a HDD read error appears on the display.

When replacing the audio-navigation unit, be sure to give the client the new anti-theft security code.

Symptom Diagnosis

Certain circumstances and system limitations may result in occasional vehicle positioning errors. Some clients may think this indicates a problem with the navigation system when, in fact, the system is normal. Keep the following items in mind when interviewing clients about symptoms of the navigation system.

Self-Inertial Navigation Limitations

The limitations of the self-inertial portion of the navigation system (the yaw rate sensor and the vehicle speed signal) can cause discrepancies between the vehicle's actual position and the indicated vehicle's position (GPS vehicle position).

The following circumstances may cause vehicle positioning errors

1. Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if the vehicle is spun on a turn table.
2. Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in travel distances. Examples of this include: Continuous tire slippage on a slippery surface Driving with snow chains mounted Abnormal tire pressure - Incorrect tire size Frequent lane changes across a wide highway Continuous driving on a straight or gently curving highway Very bumpy roads
3. Tolerances in the system and map inaccuracies sometimes limit how precisely the vehicle's position is indicated. Examples of this include: Driving on roads not shown on the map (map matching is not possible) Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking garage Driving on a road with a series of sharp hair-pin turns Driving near a gradual highway exit or transition Driving on one of two close parallel roads Making many 90 degree turns

Global Positioning System (GPS) Limitations

The GPS cannot detect the vehicle's position or elevation during the following instances

1. For the first 5 to 10 minutes after reconnecting the battery (this process can take as long as 45 minutes).
2. When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, inside parking structures or large trucks.
3. When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the vehicle. The GPS antenna requires a clear unobstructed view of the sky.
4. When there is no satellite signal output (signal output is sometimes stopped for satellite servicing).
5. When the satellite signals are blocked by the operation of some electronic aftermarket accessories including, but not limited to non-OEM in-dash entertainment units (radio, CD players/changers, radar detectors and theft recovery systems) and cell phones placed near the navigation system.

The accuracy of the GPS is reduced during these instances

1. Metallic window tinting above the GPS antenna.
2. When only three or less satellite signals are received (Four satellite signals are required for accurate positioning).
3. When driving near high tension power lines.
4. When the satellite signals are blocked by the operation of some electronic aftermarket accessories including, but not limited to non-OEM in-dash entertainment units (radio, CD players/audio disc changers, radar detectors and theft recovery systems) and cell phones placed near the navigation system.
5. When the satellite control centers are experiencing problems.

Muting Logic

Whenever the navigation system is giving guidance, outputs of all the speakers except the center speaker are decreased. When the voice control system is being used, all of the speakers are muted. If the AcuraLink or HandsFreeLink™ is in use, the voice control system is unavailable and a message appears onscreen.

LCD Unit Limitations

Note. The screen is not touch sensitive. Use the interface dial and buttons to select items on the screen.

1. In cold temperatures, the display may stay dark for the first 1 minute until it warms up.
2. When the display is too hot because of direct summer sunlight, it will remain dark until the temperature drops (you may see an error message displayed stating this fact).
3. When the humidity is high and the interior temperature is low, the display may appear cloudy. The display will clear up after some use.
4. Fingerprints on the screen may be noticeable. Clean the screen with a soft, damp cloth. You may use a mild cleaner intended for eye glasses or computer screens. To avoid scratching the panel, do not rub too hard or use abrasive cleaners or shop towels.

Symptom Duplication

1. When the symptom can be duplicated, verify that it is not a characteristic of the system, Review the Navigation Manual and compare it to a known-good vehicle (with the same software and database), under the same conditions. If the symptom is not the same as the known-good vehicle, follow the self-diagnostic procedures and the appropriate troubleshooting procedures.
2. When the symptom does not reappear or only reappears intermittently, ask the client about the conditions when the symptom occurred. Always ask the client to demonstrate the problem Try to establish possible user error or misunderstanding of the system Try to establish if outside interference may have been the cause Try to duplication the symptom under the same conditions the client experienced Vibration, temperature extremes, and moisture (dew, humidity) are factors that are difficult to duplicate Inspect the vehicle for after-market electronic devices (vehicle locators, amps, radar detectors, etc.) that may be hidden NOTE: When troubleshooting navigation system problems, ensure that the known-good vehicle is the same software version year and model as the vehicle being serviced. Mixing incompatible navigation systems or other system components can delay the troubleshooting process by creating symptoms or issues unrelated to the original problem.

Audio-Navigation Unit and HDD Service Precautions

Contrary to previous generations of navigation units, the audio-navigation unit and the HDD cannot be substituted separately. You can substitute a combined audio-navigation unit and HDD with a known-good combined audio-navigation unit and HDD. When the audio-navigation unit and HDD are connected to a vehicle, and powered up for the first time, the audio-navigation unit and HDD go through a mating process where the HDD writes the audio-navigation unit's serial number to its memory. The audio-navigation unit and HDD are available separately.

When you get a replacement audio-navigation unit, the unit arrives able to mate one time to a HDD. When you connect the audio-navigation unit to the HDD and power it up for the first time, the two components are mated. Once the audio-navigation unit is mated, it does not accept an HDD that is already mated to another audio-navigation unit. It does accept a new HDD.

The HDD is removable from the audio-navigation unit. If the audio-navigation unit is replaced, install the original HDD into the new audio-navigation unit. When you transfer the HDD, all the client's settings, music, and photographs are transferred.

The HDD is able to mate more than once, allowing you to transfer the HDD with the client's information to a new audio-navigation unit. The HDD must mate to a new audio-navigation unit. It cannot mate to an audio-navigation unit that has been mated to another HDD.

If you need to replace the HDD, there is no way to transfer client data, music, or pictures to a new HDD. Explain to your client that their music and personal information is not transferable. The navigation system has the save users memory function available, but Acura does not recommend using it. If the HDD is OK, install it in the new audio-navigation unit and it will automatically transfer all the client's information and settings.

If you need to replace the HDD, you can try to back-up the navigation data (if possible) and transfer it to the new HDD. See Save Users Memory (see SAVE USERS MEMORY ). The save users memory function only copies client settings and phone information. There is no way to copy or transfer music and photographs that are saved on the HDD to a new HDD. Explain to your client that this information is not transferable and will be lost.

1. When the battery is disconnected, the internal GPS clock resets to 0:00. The clock resets to the correct time after the system finishes GPS initialization.
2. Before disconnecting the battery, make sure you have the anti-theft code for the navigation system. Also obtain any PGM-FI or A/T DTCs and freeze frame date (which are lost when the ECM/PCM loses power).
3. After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from 10 to 45 minutes.
4. Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
5. Before returning the vehicle to the client, enter the anti-theft code for the navigation system.
6. Enter the client's audio presets.
7. Install any discs that were removed.

System Initialization

If the navigation system loses power (like the battery was disconnected), the navigation system requires initialization. Once completed, your system is ready to use.

This initialization requires the following

1. Entering the 5-digit anti-theft security code to unlock the system.
2. GPS initialization (may not be needed depending of the length of time the system was without power).
3. Map matching aligns the GPS to a location on the map.

Entering the Security Code

Any time the navigation system loses power, you need to enter the 5-digit anti-theft code on the navigation system display. This 5-digit code is located on a small code card that was given to the client. Enter the 5-digit code.

If the anti-theft code is missing, get the serial number from the audio-navigation unit and use the iN to look it up. You do not need to remove the audio-navigation unit. See Anti-Theft Feature.

When replacing the audio-navigation unit, make sure you give the client the new anti-theft security code.

GPS Initialization

Note. You must park the vehicle outside with a clear view of the sky.

Depending on the length of time the battery was disconnected, your system may require GPS initialization. If it does, the following screen appears

Scheme 925

If this procedure is not necessary, the system proceeds directly to the Disclaimer screen. During initialization, the system searches for all available GPS satellites, and obtains their orbital information. During this procedure the vehicle should be out in the open with a clear view of the sky.

If the navigation system finds the satellites properly, this box clears, and changes to the Disclaimer screen. If within 10 minutes the system fails to locate a sufficient number of satellites to locate your position, the following screen appears

Scheme 926

If this screen appears, turn off the engine, then restart the vehicle and move it to a different location. If the Disclaimer screen appears, the GPS initialization is complete.

Note. The average acquiring time is less than 10 minutes, but it can take as long as 45 minutes. If the system is still unable to acquire a signal, follow the instructions on the screen. If this screen appears again, go to GPS icon is white or not shown troubleshooting (see GPS ICON IS WHITE OR NOT SHOWN ). Skip to a CSF screen by pushing the MENU and INFO/PHONE buttons at the same time and can move to a System Links screen.

Map Matching

This part of the initialization matches the GPS coordinates with a road on the map screen. To do this part of the procedure, make sure that the navigation system displays a map, and drive the vehicle on a mapped road shown on the map screen. Do not enter a destination at this time. When the name of the current road you are driving on appears at the bottom of the screen, the entire procedure is complete. Your system is now ready to use.

Ordering an Update Navigation DVD

If the client wants to purchase a yearly update for their HDD, there are two ways to purchase one. You can either call 888-549-3798, or order on-line at www.acuranavi.com.

When clients order an update DVD, they need

1. VIN
2. Device number (found on the INFO menu)
3. Credit card

Update DVDs are available for purchase usually in the fall of each year. They may contain the following

1. Enhanced maps and points of interest (POI) coverage
2. Fixes for minor software bugs
3. Additional features

The update DVD is mailed to the client along with the password.

When the client receives the update DVD, insert the disc into the CD/DVD player. The client is prompted to enter the password that is shipped with the update DVD. The navigation system automatically updates the HDD.

Note. The update DVD is designed to update the vehicle with the submitted VIN. If a client has more than one vehicle that needs updating, they need to order a separate update DVD for that vehicle.

Acura tracks the map software version purchased for the VIN. If you need to replace the HDD, the new HDD comes with the latest map version that the client loaded on the HDD.

Never promise your client future free updates. There are no free programs for updating the navigation HDD. Update DVDs are generally available for purchase each fall. The online DVD order site provides information when an update is available.

Disconnecting

To disconnect the connector, pull the lever (A) while pushing the lock tab (B) down, then pull the connector (C).

Scheme 927

Connecting

To connect the connector, push the connector into the connector sleeve (A). As the connector is pressed in, the lever (B) moves to the locked position.

Scheme 928

How to Answer Client Questions about Navigation Coverage

Some clients may ask questions regarding a city, address, or POI (point of interest) covered by the navigation system. It is better to verify a coverage question on an actual vehicle than to disappoint your client by promising coverage that may be incomplete or missing in their area. The following suggestions can be used to answer coverage inquiries from your client.

Is my address covered by the navigation system?

Using a current production vehicle (of the same model), and enter the client's address (street first) to see if their area is covered. Always enter the street first, because sometimes their city may be included in a neighboring township, or under some larger metropolitan city name. If the address is shown in a later year vehicle, but not your client's vehicle, you might recommend that your client purchase an update.

Is my city covered by the navigation system?

For general questions about whether a city is covered, view the map coverage link on the DVD order site. On the site, select a year, and select a model, then click on the Coverage link. You then select a state or province, and the cities are listed. This does not guarantee that the client's road or address is in the system. Verifying on an actual production vehicle is always the best guarantee that your information is accurate.

The gas station on my corner is now a restaurant. Why is it still incorrect in the navigation system?

For POI-related client questions, explain that businesses are constantly moving, and there can be a considerable lag in updating the millions of POIs in the system. The database is updated annually, and the best way to the verify whether the POI is accurate is verify the inquiry on a current production vehicle.

Answers to these and other questions regarding coverage can be found in these locations

1. In the Frequently Asked Questions information of the Navigation Manual.
2. At the online DVD order site, by clicking on the FAQs link.

How do I find the local address of a business that is part of a national chain (for example, Starbucks)?

There are three ways to find the local address to businesses

1. If you know the phone number of the business, select Phone Number and enter the 10 digit phone number (area code plus seven digit number).
2. Select Category, then Restaurant. Enter the keyword Star. The resulting list includes all restaurants that have the letters Star anywhere in the name.
3. Select Name and enter Starbucks. For more common business names, like McDonalds, you may have to search through a list that includes other businesses like McDonalds Welding, McDonalds Automotive, etc.

Why are some features different or missing compared to my previous Acura vehicle?

Hardware and software continually go through updates and improvements. Features may change or disappear overtime based on the navigation system development.

How to Check Error History (Navigation DTCs)

Note. The navigation DTCs cannot be retrieved with the HDS.

The Error History feature is to record intermittent navigation issues that occur while the client is using the system. Sometimes the client complaint cannot be duplicated. The error history may record the information needed to diagnose the problem. To check the error history.

Audio-Navigation Unit and HDD Replacement Troubleshooting

To protect client information and data from theft, the audio-navigation unit and the HDD have a passcode that prevents the HDD from being accessed by any audio-navigation unit. When the HDD is first installed in an audio-navigation unit, and the ignition switch is turned to ON (II), the HDD writes the passcode from the audio-navigation unit to its memory, which is also known as mating. Every time the ignition switch is turned to ON (II), the audio-navigation unit and HDD confirm the passcode against the other component. If the audio-navigation unit has a different passcode than the HDD, the audio-navigation unit cannot access the HDD.

When you order a new audio-navigation unit, it arrives able to mate one time to a new or previously mated HDD. When you mate the two components, the new audio-navigation unit overwrites the HDD's original passcode with the new one. If you try to install the HDD back into the original audio-navigation unit, the passcode is different, and the audio-navigation unit cannot mate to the HDD.

When you order a new HDD, it arrives able to mate to a new or a previously mated audio-navigation unit. Once the HDD is mated, it then can only mate with a new audio-navigation unit.

For more information, refer to AUDIO-NAVIGATION UNIT AND HDD SERVICE PRECAUTIONS . The outline of the audio-navigation unit and the HDD replacement and substitution is shown in the following table.

Note. Original units are known-good units that have been mated at least one time, and new units have never been mated. You can substitute a mated audio-navigation unit and HDD into another vehicle, but you cannot substitute known-good components individually.

Overview

The navigation system is a highly-sophisticated, hybrid locating system that uses satellites and a map database to show you where you are and to help guide you to a desired destination.

The navigation system receives signals from the global positioning system (GPS), a network of 24 satellites in orbit around the earth. By receiving signals from several of these satellites, the navigation system can determine the latitude, longitude, and elevation of the vehicle. In addition, signals from the system's yaw rate sensor and the ECM/PCM (vehicle speed pulse) enable the system to keep track of the vehicle's direction and speed of travel.

This hybrid system has advantages over a system that is either entirely self-contained or one that relies totally on the GPS. For example, the self-contained portion of the system can keep track of vehicle position even when satellite signals cannot be received. When the navigation system is on, the GPS can keep track of the vehicle position even when the vehicle is transported by ferry.

The navigation system applies all location, direction, and speed information to maps and calculates a route to the destination entered. As you drive to that destination, the system provides both visual and audio guidance.

The navigation system also uses dynamic route guidance to help avoid traffic delays and incidents. Clients need to subscribe to real-time traffic for this function to work.

This navigation system also has voice recognition that allows voice control of most of the navigation functions. The TALK and BACK buttons on the steering wheel activate the voice control. The voice control also allows control of the audio and climate functions.

The illumination signal (headlights ON) is used by the audio-navigation unit to automatically switch the display between Night and Day brightness modes. When the gauge control module brightness control is set to full brightness, the navigation system stays in the day mode, even with the headlights on.

The GA-Net II communication bus passes information back and forth between the navigation display, the audio-navigation unit, AcuraLink control unit (XM receiver), and the audio system. The information passed on this bus is audio settings directed by the audio-navigation unit.

The Comm. Bus connects the HFL, XM (HIP) (AcuraLink), and audio-navigation units. This bus supports these functions

1. The audio-navigation unit receives traffic, weather, and AcuraLink message information from the AcuraLink control unit (XM receiver).
2. If a POI phone number is available, the audio-navigation unit sends the phone number (on the Calculate route to screen) to the HandsFreeLink™ control unit for dialing.
3. If vehicle problems are detected, and the client's cellular contract includes data service (the vehicle must also have an approved blue tooth phone paired and configured correctly), then the AcuraLink control unit (XM receiver) can send vehicle data to the HandsFreeLink™ control unit for transmitting back to the AcuraLink servers.
4. The AcuraLink server can pass additional problem details back through the HandsFreeLink™ control unit, to the AcuraLink control unit (XM receiver), and finally to the audio-navigation unit for display.

HDD Navigation System

The Acura TSX uses a HDD (hard disc drive) instead of a navigation DVD. The HDD system improves route calculation and POI searching time, as well as these additional functions

1. Ripping music to the HDD with on-board CDDB (CD database) information provided by Gracenote.
2. Clients can save their personal pictures to the HDD and use the images as wallpaper when they are not using the navigation system.
3. See the Owner's Manual or Navigation Manual for more information.

There are two software programs that run on the navigation system

1. Navigation system software - This software comes pre-loaded on the HDD and runs the navigation system. It can be updated when a client orders a navigation update disc, or as directed by any official Acura service information like a service bulletin.
2. Map software - This is commonly referred to as update navigation DVD that clients can order to update their map info, POI DB, and CDDB information. This also comes pre-loaded on the HDD, but the client can choose to update it yearly.

When you order a reman HDD, the latest navigation system software is loaded on the HDD, along with the latest Map software that the client had installed on their HDD.

If a client wants to order an update, see Ordering an Update Navigation DVD (see ORDERING AN UPDATE NAVIGATION DVD ).

The Gracenote CDDB is updated quarterly. Clients can visit www.acura.com and download the latest update.

The HDD shuts down to protect itself from damage, if the audio-navigation unit internal temperature is 183°F (84°C) or higher.

Warning of extreme temperatures in the audio-navigation unit is displayed on the navigation screen as an error message.

USB Adapter

The USB module is built into the audio-navigation unit. Clients can load images (which can be used as wallpaper), music, and the CDDB. Not all USB devices and devices functions work with the USB adapter. Please see the Owner's Manual for more information.

Navigation Function

The navigation system is composed of the audio-navigation unit, the ECM/PCM (vehicle speed pulse), the AcuraLink control unit (XM receiver) (traffic and weather information), the HandsFreeLink™ control unit (to send a POI phone number or place a call), the GPS antenna, the microphone, the voice control switch, the navigation display unit, the interface dial, and the rearview camera.

Scheme 939

GA-Net Bus Configuration

The GA-Net bus passes audio, navigation, and HFL commands throughout the audio, navigation, and HFL components. These commands include navigation audio/XM selections by voice, and XM station and music title names. Because the entire bus is interconnected between components, an open or short in the GA-Net bus harness may cause any or all of these functions to become inoperative.

Scheme 940

Vehicle Speed Pulse

The vehicle speed pulse is sent by the ECM/PCM. The ECM/PCM receives a signal from the output shaft (countershaft) speed sensor, then processes the signal and transmits it to the speedometer and other systems.

Scheme 941

Yaw Rate Sensor

The yaw rate sensor (located in the audio-navigation unit) detects the direction change (angular speed) of the vehicle. The sensor is an oscillation gyro built into the audio-navigation unit.

Sensor Element Structure

The sensor element is shaped like a tuning fork, and it consists of the piezoelectric parts, the metal block, and the support pin. There are four piezoelectric parts: one to drive the oscillators, one to monitor and maintain the oscillation at a regular frequency, and two to detect angular velocity. The two oscillators, which have a 90-degree twist in the center, are connected at the bottom by the metal block and supported by the support pin. A detection piezoelectric part is attached to the top of each oscillator. The driving piezoelectric part is attached to the bottom of one oscillator, and the monitoring piezoelectric part is attached to the bottom of the other oscillator.

Oscillation Gyro Principles

The piezoelectric parts have electric/mechanical transfer characteristics. They bend vertically when voltage is applied to both sides of the parts, and voltage is generated between both sides of the piezoelectric parts when they are bent by an external force. The oscillation gyro functions by utilizing this characteristic of the piezoelectric parts and Coriolis force. (Coriolis force deflects moving objects as a result of the earth's rotation.) In the oscillation gyro, this force moves the sensor element when angular velocity is applied.

Scheme 942

1. The driving piezoelectric part oscillates the oscillator by repeatedly bending and returning when an AC voltage of 6 kHz is applied to the part. The monitoring-side oscillator resonates because it is connected to the driving-side oscillator by the metal block.
2. The monitoring piezoelectric part bends in proportion to the oscillation and outputs voltage (the monitor signal). The navigation unit control circuit controls the drive signal to stabilize the monitor signal.
3. When the vehicle is stopped, the detecting piezoelectric parts oscillate right and left with the oscillators, but no signal is output because the parts are not bent (no angular force).
4. When the vehicle turns to the right, the sensor element moves in a circular motion with the right oscillator bending forward and the left oscillator bending rearward. The amount of forward/rearward bend varies according to the angular velocity of the vehicle.
5. The detecting piezoelectric parts output voltage (the yaw rate signal) according to the amount of bend. The amount of vehicle direction change is determined by measuring this voltage.

Global Positioning System (GPS)

The global positioning system (GPS) enables the navigation system to determine the current position of the vehicle by using the signals transmitted from the satellites in orbit around the earth. The satellites transmit the satellite identification signal, orbit information, transmission time signal, and other information. When the GPS receiver receives a signal from four or more satellites simultaneously, it calculates the current position of the vehicle based on the distance to each satellite and the satellite's position in its respective orbit.

Scheme 943

Precision of GPS

The precision of the GPS varies according to the number of satellites from which signals are received and the view of the sky. The accuracy is indicated by the color of the GPS icon shown on the display.

GPS REFERENCE CHART

GPS Antenna

The GPS antenna amplifies and transmits the signals received from the satellites to the GPS receiver.

GPS Receiver and Clock

The GPS receiver is built into the audio-navigation unit. It calculates the vehicle position by receiving the signal from the GPS antenna. The current time, vehicle position and signal reception condition is transmitted from the GPS receiver to the audio-navigation unit to adjust vehicle position and the clock in the audio-navigation switch panel display.

Audio-Navigation unit

The audio-navigation unit calculates the vehicle position and guides you to the destination. The unit performs map matching correction, GPS correction, and distance tuning. It also controls the menu functions and the HDD, and interprets voice commands. With control of all these items, the audio-navigation unit makes the navigation picture signal, then it transmits the signal to the navigation display unit.

Calculation of Vehicle Position

The audio-navigation unit calculates the vehicle position (the driving direction and the current position) by receiving the directional change signals from the yaw rate sensor and the travel distance signals from vehicle speed pulse (VSP) signal of the ECM/PCM.

Map Matching Tuning

The map matching tuning is accomplished by indicating the vehicle position on the roads on the map. The map data transmitted from the HDD is checked against the vehicle position data, and the vehicle position is indicated on the nearest road. Map matching tuning does not occur when the vehicle travels on a road not shown on the map, or when the vehicle position is far away from a road on the map.

GPS Tuning

The GPS tuning is accomplished by indicating the vehicle position as the GPS's vehicle position. The audio-navigation unit compares its calculated vehicle position data with the GPS vehicle position data. If there is large difference between the two, the indicated vehicle position is adjusted to the GPS vehicle position.

Distance Tuning

The distance tuning reduces the difference between the travel distance signal from the VSP and the distance data on the map. The audio-navigation unit compares its calculated vehicle position data with the GPS vehicle position data. The audio-navigation unit then decreases the tuning value when the vehicle position is always ahead of the GPS vehicle position, and it increases the tuning value when the vehicle position is always behind the GPS vehicle position.

Traffic Information

The Acura navigation system's real-time traffic feature helps you avoid traffic delays by providing up to the minute traffic information in many metropolitan areas across the contiguous USA. Color coded freeways appear on the navigation screen, displaying current traffic flow, and/or the locations of accidents and traffic conditions affected by construction and weather. Real-time traffic data services are offered on a subscription basis for a nominal fee following the 90-day free trial period.

Weather Information

The Acura navigation system's weather information option allows you to view the weather forecast, warning list, warning map, and weather radar. The weather information is available in a subscription basis for a fee following the 90-day free trial period.

Dynamic Route Guidance

The audio-navigation unit can calculate different routes to a selected destination. You have five options

1. Direct Route-Calculate a route that is the most direct.
2. Easy Route-Calculate a route that minimizes the number of turns needed.
3. Minimize Freeways-Calculate a route that avoids freeway travel. If that is not possible, keep the amount of freeway travel to a minimum. This is not selectable (button grayed out) for trips greater than 100 miles.
4. Minimize Toll Roads-Calculate a route that avoids, or minimizes travel on toll roads. This is not selectable (button grayed out) for trips greater than 100 miles.
5. Maximize Freeways-Calculate a route that uses freeways as much as possible.

Audio Guidance

The audio-navigation unit transmits audio driving instructions before entering an intersection or passing a junction. The audio instructions come through the stereo amplifier to the front speakers.

Note. The front speakers are muted whenever the navigation system is giving guidance commands, and all of the speakers when the voice control system is being used.

Muting Signal Logic

The audio muting logic is orchestrated by the audio-navigation unit. The audio-navigation unit determines what audio source has priority to use the speakers.

The priority of the audio sources is as follows

HFL has the highest priority, followed by navigation, and finally the radio/CD-DVD player. The priority is passed by HFL to the audio-navigation unit by dedicated mute wires. The navigation mute signal is passed to the stereo amplifier.

The audio-navigation unit temporarily disables the voice control buttons, but allows guidance to be heard. In addition, the audio-navigation unit suppresses the output from the audio system, the XM receiver, the disc player, or other audio accessories.

When the navigation system sends out a voice route guidance command, the audio front speaker is muted, and the navigation voice is heard in the front speakers.

When the navigation voice control system is in use, all of the speakers are muted, and the navigation voice prompts are heard from the front speakers.

Solar Angle

The climate control unit uses the sun's angle, along with the sunlight sensor to control the driver/passenger A/C air flow.

Off Road Tracking (bread-crumbs)

Off road tracking dots that can be followed on the map retrace your route back to a mapped (digitized) road.

Clock and Time Zone

The clock set up allows you to set daylight savings time, auto time zone and time adjustment.

GPS Information

This screen shows the current status of GPS reception. The circular diagram shows the current location of the GPS satellites (yellow numbers) as they would appear in the sky. The outer circle represents the horizon (0 degrees elevation). The middle and inner circles represents 30 and 60 degrees respectively. The very center of the diagram (90 degrees elevation) is directly overhead. Nearby obstructions, like tall buildings will block satellites in that direction. That is why it is necessary to be in an open area to effectively troubleshoot GPS reception issues. The satellite numbers shown on the diagram correspond to the PRN number in the GPS Details screen. There are always at least 24 active GPS satellites in orbit. Because satellites fail, and have to be removed from service, spares are always parked in orbit, ready to be activated. This is why the PRN (satellite ID number) can be greater than 24.

Note. When you use this screen for troubleshooting, park the vehicle outside, away from buildings, tall trees, and high-tension wires for at least 10 minutes with the engine running.

Scheme 1021

1. The Number of Satellites box shows the number of acquired satellites (maximum of 12). It should contain four or more icons. If not, go to GPS icon is white or not shown troubleshooting (see «GPS ICON IS WHITE OR NOT SHOWN»(/acura/tsx/ii-2008-2014/remont/entertainment-systems/#navigation-system-4-cyl__gps-icon-is-white-or-not) ).

2. The Speed and Direction information is updated in real time when driving.
3. The Date/Time Information is the same as in Setup screen 2 Adjust Time Zone/Clock.
4. If the 3D icon is shown above the yellow dots, this implies that at least four satellites are available for map positioning, and the GPS indicator on the map screen will be green. See the Global Positioning System detailed explanation in the System Description.
5. If the row of data in the table below begins with a yellow dot, the AZI and EL fields can be used to locate each satellite on the circular GPS diagram (see prior screen).

The table of values shown below define the terms at the top of the columns in the GPS detail screen.

PROBLEM INDICATION CHART

Yaw Rate

This diagnosis checks the yaw rate sensor in the audio-navigation unit. This device detects when the vehicle turns, and repositions the vehicle position icon on the map screen. For more detailed information, see the yaw rate sensor theory of operation under System Description (see YAW RATE SENSOR ).

1. Sensor indicates the voltage output from the yaw rate sensor. It should indicate about 2.500 V when the vehicle is stopped.
2. Offset is the reference voltage or standard within the yaw rate sensor. It also should indicate about 2.500 V when the vehicle is stopped.
3. A sensor output voltage LOWER than the Offset voltage indicates that the vehicle is turning to the right.
4. A sensor output voltage HIGHER than the Offset voltage indicates that the vehicle is turning to the left.
5. The yaw rate offset, and sensor should both indicate about 2.500 V when the vehicle is stopped. If either reads zero, or 5.000 V, replace the audio-navigation unit (see «AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION»(/acura/tsx/ii-2008-2014/remont/entertainment-systems/#navigation-system-4-cyl__audio-navigation-unit-removalinstallation) ).
6. The yaw rate offset and sensor should be within +/-0.01 V of each other when the vehicle is stopped. The sensor value should change relative to the offset as the vehicle turns while driving. If not, replace the audio-navigation unit (see «AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION»(/acura/tsx/ii-2008-2014/remont/entertainment-systems/#navigation-system-4-cyl__audio-navigation-unit-removalinstallation) ).

Example: Car stopped

Normal Abnormal

Offset 2.526 V Offset 2.526 V

Sensor 2.516-2.536 V Sensor 2.623 V

Example: Car turning

Normal Abnormal

Offset 2.526 V Offset 2.526 V

Sensor 2.678 V (left turn) 2.478 V (right turn) Sensor 2.623 V (no change on turns)

Scheme 1023

1. The settings CCW Cal Factor, CW Cal Factor, and Set are for factory use only. THIS SHOULD NEVER BE ADJUSTED.
2. For detailed analysis of the yaw rate select tuning.

Yaw Rate Tuning

This diagnosis allows you to graphically display problems with the yaw rate sensor.

1. The ANG-Disp value accumulates any differences between the offset, and sensor voltages (see Yaw Rate diagnostic). When the sensor functions normally, the random changes in these two voltages generally cancels out, so the value is 0. However if one voltage is consistently higher than the other, then the ANG-Disp value accumulates the constant change.
2. The Reset button temporarily clears the angular accumulation (ANG-Disp), and clears the display dots.
3. Do not touch the CCW, CW, or Set buttons. These are used for factory setup only.

Two tests are explained below. For gross problems with the sensor, the stationary test usually confirms whether the sensor is defective. For yaw rate issues related to driving, do the road test described below.

Scheme 1024

1. Stationary test: If the VP icon spins with the vehicle parked and the engine running and the ANG-Disp value slowly increases or decreases, the yaw rate sensor is defective. Replace the audio-navigation unit (see «AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION»(/acura/tsx/ii-2008-2014/remont/entertainment-systems/#navigation-system-4-cyl__audio-navigation-unit-removalinstallation) ).
2. Road test: Drive the vehicle on a very straight, smooth road. Enter the diagnostic mode, select Yaw rate, and touch the Tuning button. While driving down a straight road, the white dots should trace a straight line across the screen. However, if you are driving on a straight road, and you notice the dots constantly dropping down or heading up as you drive, the audio-navigation unit's yaw sensor is defective. To run the test again, touch Reset to clear ANG-Disp, and the dotted lines. If either test above fails, please enter Yaw rate sensor defective for the problem description, on the audio-navigation unit return form. NOTE: The CCW, CW and Set buttons are disabled and cannot be activated.

Car Status

Use this screen to confirm that the audio-navigation unit is properly receiving input signals. Signals equal to (0) are OFF, and signals equal to (1) are ON. If the value on the display does not match the actual vehicle status, then check the wire carrying the signal.

1. VSP-Vehicle Speed Pulse from ECM/PCM (audio-navigation unit connector A (24P) terminal No. 15) OFF (0) when vehicle is not moving ON (1) when vehicle is moving

The VSP comes from the ECM/PCM as a dedicated signal. Internally, the audio-navigation unit compares the actual VP on the map against street data to adjust the pulse to speed scaling factor. As this scaling factor becomes more accurate, the Level gradually increases from 0 to 10.

1. BACK-Reverse indication from taillight relay (audio-navigation unit connector H (28P) terminal No. 20) OFF (0) when the shift lever is in any position other than reverse ON (1) when the shift lever is in R position

The Back signal is used by the audio-navigation unit to allow the map screen to show the VP moving backwards when the vehicle is in R position. This signal is needed because the Speed Pulse has no direction indication.

Scheme 1025

1. ILL-Illumination Indication (audio-navigation unit connector H (28P) terminal No. 4) OFF (0) when parking lights, or headlights are off ON (1) when parking lights, or headlights are on

The navigation uses the signal to determine whether to put the navigation screen into the Day or Night brightness mode. (Setup screen 1)

Note. The PARK on this diagnostic screen in this models always shows [-]. You will not see this display when you shift into R because the screen displays the rearview camera image.
