Introduction

Range Rover up to 2005 model year has the option to be supplied with a built in hands free telephone system. Both the Multi-Function Display (MFD) and the Multi Information Display (MID) are capable of supporting telephone operation. The system is based around a portable GSM phone which utilizes a standard SIM card.

The following describes key points regarding the telephone system fitted to the new Range Rover.

1. The telephone system is only compatible with GSM 900
2. Only one handset can be registered to one vehicle at any one time. Handsets need to be de-registered before a replacement handset can be registered to a vehicle
3. New SIM card holders can be purchased through the handbook ordering process
4. Only Land Rover approved SIM card holders should be used. Tests indicate that non approved SIM card holders can release the SIM card into the reader. Removal of the SIM card from the reader is extremely difficult and could cause damage to the reader
5. The telephone ECU does not support the use of the * and # keys. This means that GPRS and pay as you go type services are not supported
6. The telephone system does not support 5v SIM cards. Normally the service provider will change the SIM card for a 3v version. There is no way of identifying the SIM card voltage from the card
7. The use of dual SIM cards is only supported by some service providers usually at an extra cost.

Telephone System

The telephone system comprises the following components

1. Eject box
2. Cordless handset
3. Cordless handset antenna
4. Telephone ECU
5. Multi band antenna
6. Hands free microphone.

Three 'status' LEDs, fitted either on the lower right hand side of the MID or on the upper right hand side of the MFD, indicate the status of the telephone system as follows

STATUS CHART

Scheme 3

The eject box is located in the center arm rest console. It holds the handset and also a SIM card reader. The SIM card reader requires the use of an adaptor to allow the use of standard small size SIM cards.

When the handset is in the Eject box the hand set battery will be charged if the ambient temperature is between 0°C and 40°C.

To release the hand set from the eject box the eject key located at the front of the box should be depressed. This raises the hand set approximately 15° out of the rest position. The eject key inscription is illuminated and this illumination is variable with the use of the instrument dimmer switch.

Scheme 4

The Cordless hand set has a graphic display on which a maximum of 4 lines each with 16 characters can be shown. In the first line, information concerning the mobile state ("Phone locked; "Connected") or the battery charge state is displayed. In the second and third lines there are various formats for inputting optional digits. In the fourth line only the softkey fields are displayed. Either as a symbol or as fixed text. On activating the menu key, the second and third line of the display is available for menu selections. When menu selection is concluded the display returns to normal. All texts can be displayed in upper or lower case. This includes both the mobile handset permanent text items (e.g. menu texts) and texts edited by the user (e.g. names in phone book) The following information is displayed in the handset switched-on state, however it is not necessarily displayed during menu navigation

1. Permanent display of battery charge state
2. Permanent GSM signal strength.

With the batteries fully recharged, the handset can remain on stand-by for approximately 48 hours and has an air time of approximately three hours. If the batteries are completely flat or if new batteries have been inserted, full charging will take approximately six hours. To charge the batteries, place the handset in the eject box. The batteries are also charged while the car is parked (ignition off).

The handset is connected with the base station in the car by radio link. This link can be switched off for workshop purposes or where it is a market requirement. When using the handset, ensure that this switch always remains in position "1" (to the right).

Cordless Handset Replacement

The following describes the manual process for replacing a handset. Before handset replacement is started it must be remembered that only one handset can be registered to a vehicle and that prior to a new handset being registered the old handset must be de-registered. The process of registering and de-registering can be carried out using T4.

The following steps should be carried out to manually de-register a handset from a vehicle.

1. Insert the SIM card into the holder and insert it in the reader
2. Turn "ON" the ignition
3. Turn "ON" the handset
4. Select "MENU" on the handset

6. Scroll down to "SERVICE SETTING" and press "OK"
7. Select "LOG OFF" and press "OK"
8. "OWN MOBILE UNIT" displayed select "OK"
9. "LOG OFF MOBILE" is displayed press "OK"

The process is now complete. The handset should display "PLEASE LOG ON".

The following describes the process for manually registering a new phone to a vehicle. Again it should be remembered that only one phone can be registered to a vehicle and that any other phone should be de-registered prior to trying to register a new phone.

Replacement handsets will be supplied from the manufacturer in German. Language changes can only be made once the phone is registered to the vehicle, therefore the registration process for new phones must be completed in German.

1. The Ignition must be "ON" and phone must be switched "ON" for a minimum of 10 seconds. NB it is not necessary to have the SIM card inserted to register a handset
2. The handset display will show "BITTE ANMELLDEN" (PLEASE REGISTER)
3. Turn the ignition "OFF" and remove the phone from the eject box
4. Switch the eject box switch to position "O" within 10 seconds
5. Turn the eject box switch to position "I" within 5 seconds
6. Press the "OK" button on the handset, the handset should display "GERATE CODE" (ENTER CODE)
7. Enter 0000 and press the "OK" button
8. The handset will display "ANMELLDEN LAUFT" when registered
9. The handset will then display "BITTE SETTEN SIE IHREKARTEIN" (PLEASE INSERT THE SIM CARD)

The process is complete. Note that the handset will still display in German.

Once the registration process is complete the handset language need to be changed.

1. With the SIM card in and the ignition "ON" turn on the handset. The handset will display "SUCHE BASIS" (SEARCHING BASE)
2. When the service provider is displayed on the handset, press the "MENU" button
3. Press 7 to select option 7 in the menu
4. The display will show "SPRACHE" press "OK"
5. Highlight the desired language and press "OK"
6. Return to main menu

The handset should now display in the chosen language.

Scheme 5

The cordless handset antenna is located in the left hand side of the luggage compartment. This antenna allows the cordless handset to communicate with the Telephone ECU.

Scheme 6

The TCU located in the left hand side of the luggage compartment. The TCU sends and receives signals from the cordless handset via the handset antenna. The TCU then sends and receives signals to the GSM antenna via a co-axial cable. If the unit needs replacing, it must be configured using T4.

Scheme 8

The antenna is located in the rear tailgate spoiler and is the same component for most world markets.

Voice control enables the driver to activate important functions of the car telephone and navigation systems without needing to operate any controls manually. This allows the driver to concentrate fully on driving the vehicle. Whenever the driver issues one of the defined voice commands with the system active, the voice control system converts the command into a control signal for the telephone or navigation system. The system recognizes which system the command is directed at and routes the direction accordingly. The driver is guided through the dialogues by announcements or questions.

The voice recognition system is only available in the following language variants

1. UK English
2. US English
3. Italian
4. German.

The voice control system understands around 50 pre-defined commands, which need to be given exactly, word for word. The driver can prompt the system to speak a selection of the most used commands by activating the system and giving the command HELP.

If it becomes necessary to place an emergency telephone call, it is recommended that the handset, the steering wheel switches, the multi information display (MID) or multi function display (MFD) is used to dial an emergency number (this presumes a number for emergency calls is stored in these systems). The reason for using the manual control is that under stress the drivers normal voice pattern may become disturbed. This will mean that the system may not recognize the voice commands being issued and cause the emergency telephone call to be delayed.

System Components

The following describes the components within the voice control system.

Scheme 9

The voice recognition ECU is located in the rear loadspace under the navigation computer where fitted. The ECU communicates with the telephone and navigation systems on the I-Bus and hard wired connections.

Scheme 10

Scheme 11

The steering wheel switch pack contains several switches for operation of the audio navigation and cruise control.

The voice recognition system is activated using an I-bus telegram. Activation is achieved by pressing and holding the voice recognition key on the steering wheel switch pack until an acoustic signal is heard.

Microphone

A single microphone is used for hands-free telephone operation and for the voice recognition system. The microphone has an integrated noise suppression system for hands-free telephone use.

If replaced the microphone must be correctly orientated. This is achieved by ensuring the arrow on the back of the microphone is facing the front of the vehicle.

Scheme 12

Voice Recognition System Operation

To access voice control of the telephone system, press the key on the steering wheel switch pack.

1. A brief press of the key (for longer than 750 ms) activates the normal telephone functions
2. Holding the key pressed in (until the acoustic signal is heard) activates voice control.

A brief acoustic signal and the display "VOICE RECOGNITION" in the instrument pack message center indicate that the system is now in the stand-by mode ready to receive voice commands. Any voice command can be interrupted by saying the word "CANCEL" or by pressing and holding the steering wheel switch until the system responds with the phrase "CANCEL".

Making a Phone Call

Once the system is ready to receive voice commands to dial a telephone number the user has to speak clearly.

VOICE COMMAND CHART

The system understands single digits from zero to nine. You can choose to say either Zero or Nought. Numbers such as ten, eleven, twelve, etc. are not recognized. To speed up input, it is a good idea to group together between three and five digits into a continuous string. However, you can also say each digit individually, or all digits continuously. Telephone numbers of up to 20 digits are acknowledged. If a longer number is given, the error message "The number is full" will be issued.

Voice Operation of the Navigation System

To access voice control of the navigation system, press the key on the steering wheel switch pack.

1. A brief press the key (for longer than 750 ms) activates the normal telephone functions
2. Holding the key pressed in (until the acoustic signal is heard) activates voice control.

Once the system is active the driver has three main options (in navigation mode)

1. Map mode
2. Information on current position or destination
3. Activation of destination guidance.

Map Mode

Once the system is accessed the command "ROUTE MAP" or "MAP", will bring the map mode up on the MFD.

Once the map mode is accessed it is possible to change the map scale by issuing the command "SCALE ONE HUNDRED METER" to "SCALE ONE HUNDRED KILOMETER". Valid scales are as follows

1. 100, 200, 500 meters
2. 1, 2, 5, 10, 20, 50, 100, kilometer.

Information on Current Position or Destination

Information on current position or destination is accessed by issuing the command "PETROL STATION AT CURRENT LOCATION". This causes all petrol stations in the vicinity of the vehicle to be displayed on the MFD. If a destination has been entered into the navigation system it is also possible to issue the command "PETROL STATION AT DESTINATION". A full list of petrol stations at the destination is then displayed on the MFD. Selection and guidance to the chosen petrol station is achieved by tuning the rotary controller and selecting in the usual way.

Once the command has been issued the MFD displays petrol stations along the route.

The information displayed is not limited to petrol stations. Information can be displayed on

1. Car parks
2. Hotels
3. Restaurants.

To access these functions follow the procedure outline previously replacing the petrol station command with the required function.

Destination Guidance

To access the destination guidance function the driver issues the command "DESTINATION GUIDE" or "DESTINATION GUIDANCE". The computer will start to give voice and map guidance to the chosen destination.

General

The telephone system fitted to Range Rover from 2005 model year is a completely new system. The system uses the MOST ring for communication with the rest of the entertainment and information system. The system allows the driver to dock their own phone into the integrated phone system. This is achieved using a number of phone adaptor cradles which are specific to different makes and models of phone. The phone adaptor cradle is then docked with a base plate adaptor in the vehicle. This allows the integrated phone system to control the telephone and enable the driver to make and receive telephone calls using hands free operation.

The telephone system also supports Bluetooth® technology allowing hands free operation of a Bluetooth® mobile phone. The system has limited functionality compared with the integrated phone system.

The system comprises

1. Adaptor cradle (phone model specific)
2. Base plate adaptor
3. Transceiver Module (TM)
4. Touch Screen Display (TSD)
5. Microphone
6. Integrated Head Unit (IHU)
7. Multiband antenna (roof pod)
8. Steering wheel controls
9. Audio amplifier (for audio output).
10. Navigation computer (for voice recognition if fitted)

The following describes the components used in the telephone system.

Scheme 15

Typical adaptor cradle shown

The telephone adaptor cradle is located in the center arm rest and is directly connected to the base plate adaptor. The adaptor cradle is detachable from the base plate adaptor to allow for different phones to be used in the system. A new adaptor cradle is the only requirement for the system to be changed from one type of phone to another. Adaptor cradles are available for the top 20 business phones in each market, this is subject to change as new phones come on to the market and replace older models. Adaptor cradles will be available through the accessories department.

Depending on the variant of the adaptor cradle, the cradle will have one of two ways of communicating with the phone. If the adaptor cradle is for a Nokia F Bus type phone the cradle will route the connections from the transceiver module straight through to the phone.

If the adaptor cradle is for a non Nokia F bus or a non Nokia type phone (i.e. Motorola), the cradle will have an internal circuit to convert signals from the phone to be compatible with the transceiver module signals.

Scheme 16

The base plate adaptor is located in the center arm rest. The base plate adaptor is the interface between the telephone adaptor cradle and the transceiver module. The following pin out table details the connections at the base plate adaptor from the transceiver module.

Scheme 18

The Touch Screen Display (TSD) forms the basis of the telephone system. It communicates with the rest of the audio/infotainment system on the MOST ring and allows control of the telephone system and other infotainment systems from a single point.

The TSD communicates with the Integrated Head Unit (IHU) on the MOST ring and provides the driver interface and driver display of the telephone system. The TSD also provides driver display and control of the audio, the rear view camera, the Venture Cam, the navigation system, the Traffic Message Channel and the rear seat entertainment.

The telephone system and other systems are operated by a combination of the physical buttons located on each side of the screen and the 'virtual' buttons displayed on the touch screen. For clarification, the physical buttons are referred to as 'buttons' and the touch screen virtual buttons are referred to as 'icons'. Refer to AUDIO SYSTEM COMPONENT LOCATION - FROM 2005 MY for further details on the TSD.

Scheme 19

The microphone is located in the front interior lamp console. The standard, directional type microphone is connected to the Integrated Head Unit (IHU) and the navigation computer (if fitted) for voice recognition of the navigation system and the telephone. The microphone has an integrated noise suppression system for hands-free telephone use.

Scheme 20

The Integrated Head Unit (IHU) is located behind the TSD in the center of the fascia. The IHU communicates with the TM on the MOST ring. The IHU contains the software for telephone functionality. Refer to AUDIO SYSTEM COMPONENT LOCATION - FROM 2005 MY for further details on the IHU.

Scheme 21

The multi-band antenna is located in the roof pod. Two roof pods are available to cover vehicles with and without SDARS. The two roof pods operate on the following frequencies

1. World Band - Telephone only or telephone and GPS antenna GSM and PCS/DCS and 3G 810 to 960 MHz 1710 to 2170 MHz
2. NAS Only - SDARS and telephone or SDARS and telephone and GPS antenna AMP and PCS only 824 to 960 MHz 1850 to 1990 MHz

Roof pods without SDARS contain a multiband antenna. When SDARS is fitted the roof pod contains a broadband antenna which prevents interference from the SDARS antenna affecting telephone reception.

Scheme 22

The steering wheel switches for the telephone system are located on the RH side of the steering wheel. The driver is able to use these switches for several phone related functions including

1. Accept incoming calls.
2. Reject incoming calls.
3. Make phone calls from the phones own phone book.
4. Use the voice dialling feature of the telephone system.

The 'R/T' button is used to switch between telephone and audio functions. When using the steering wheel switches in telephone mode, visual confirmation of phone book name or number is displayed in the instrument pack message center. The address book/phone book details can be scrolled through using the audio search up and down buttons. The telephone/voice recognition button is used to make a call, answer an incoming call and to end an active call. When not in phone book mode and no number is displayed in the message center, a short press of the telephone/voice recognition button will dial the last dialled number.

Scheme 23

DSP amplifier shown

The amplifier (DSP or Logic7) is located in the rear LH side of the luggage compartment. The audio amplifier receives audio from the TM on the MOST ring, the audio is then processed and passed out to the speakers. Refer to AUDIO SYSTEM COMPONENT LOCATION - FROM 2005 MY for further details on the audio amplifier.

Scheme 24

A gateway module is located behind the TSD. The gateway module is the link component between the vehicle bus systems and the audio/telephone system MOST ring. When the vehicle is unlocked, the gateway module receives a system 'wake-up' message on the CAN bus. This message is then passed on the CAN bus from the gateway module to the integrated head unit which then 'wakes-up' the MOST ring components by energizing the infotainment relay. Refer to AUDIO SYSTEM COMPONENT LOCATION - FROM 2005 MY for further details on the gateway module.

Bluetooth®

The TM has Bluetooth® functionality. Bluetooth® allows the user to connect their own mobile phone handset (Bluetooth® enabled only) to the vehicle telephone system without fitting the phone into the adaptor cradle. If a phone is fitted to the adaptor cradle this will be given priority over the system and a Bluetooth® enabled phone will be ignored.

Once connected, the user can use the vehicle hands free functions. The Bluetooth® system limits the functions to those available in the Bluetooth® hands free profile. The available features include

1. Make/receive call
2. Voice calls using the phones own voice tags (where set up).

Bluetooth® will not allow the following to be accessed via the TSD

1. Short Message Service (SMS)
2. No signal strength indication on the TSD
3. Phonebook download to the IHU
4. Missed calls
5. Last number redial
6. Calls list.

Bluetooth® Pairing

Before a Bluetooth® phone handset can be used on the vehicle hands free system, the phone must be 'paired' to the TM. The following steps describe the 'pairing' process

1. On the handset, make sure that Bluetooth® is switched 'ON'.
2. The user then initiates a search for other Bluetooth® devices from the handset.
3. The TM acknowledges the existence of the Bluetooth® phone.
4. On the handset, 'Land Rover' appears in the available device list.
5. The user selects 'Land Rover' from the device list and the TM will attempt pairing.
6. The TM requests a Personal Identification Number (PIN) from the handset.
7. The user then enters the handset PIN. The PIN will have been supplied to the customer by the dealer or can be found on the side of the TM (use the last four digits of the TM serial number).
8. If the PIN is correct, the phone handset will be paired with the TM and the handset details are stored in the TM EEPROM. The TM details are also stored in the phone handset.

Once paired, the TM periodically checks (approximately every 20 seconds) for stored Bluetooth® devices. When this occurs, the user will see a connection request appear on the phone handset display and either accepts or declines the request. This request will occur only once per ignition cycle.

When the pairing procedure is complete (assigning the phone handset to the vehicle) the phone handset will automatically connect to the vehicle system once they come into range (approximately 10 meters) and the ignition switch is in position II. A Bluetooth® icon is displayed in the TSD to inform the driver that the phone handset is connected to the TM.

Up to eight Bluetooth® equipped phone handsets can be paired with the TM. A phone handset can be de-registered/disconnected from the TM at any time by the user. Only one phone handset can be used on the vehicle hands free system at any one time.

If the TM is replaced, each phone handset which was paired with the original TM will require re-pairing with the replacement TM.

Voice Recognition

The voice recognition system controls the following systems (where fitted)

1. Telephone
2. Audio (radio and CD)
3. Note pad
4. Touch screen display
5. Rear seat entertainment
6. Navigation.

On vehicles without the navigation system, the voice recognition software is contained in the TM. The microphone is hardwired to the IHU which in turn is connected to the TM via the MOST ring. The TM will only operate voice control of the telephone system. The TM has limited language capability with German, French, Italian, Spanish, USA and UK supported.

On vehicles with the navigation system, the voice recognition software is contained in the navigation computer. The microphone is hardwired to both the navigation computer and the IHU. The navigation computer will allow voice control of the telephone system, the audio system, the rear seat entertainment and the navigation system. The navigation computer supports the same languages as the TM but with the addition of Japanese, Dutch and USA with male and female voices.

The voice recognition system enables the driver to activate important functions of the telephone system without operating controls manually. This allows the driver to concentrate on driving the vehicle, improving safety. When the driver speaks one of the defined voice commands, with the voice recognition system active, the voice recognition software converts the command into a control signal for the telephone system.

Telephone Voice Recognition Functions

The telephone can be accessed and controlled by the voice recognition system as follows

1. Dial Number This allows the user to dial a number (of up to 20 digits) by digit entry using voice commands of between "zero" and "nine". An edit facility allows changes to be made if an incorrect digit has been entered by using the command "correction". Numbers of up to 20 digits can be entered. If more than 20 digits are entered the system responds with a message 'Number too long' in the message center.
2. Phone Book The phone book allows the user to add up to 50 'nametags' with stored phone numbers. The nametags are user identifiable association names for the allocated phone number. This phone book has no connection with the phone book stored on the phone handset's SIM card or phone memory.

Voice Recognition Settings

A number of settings allow the user to customize the voice recognition system as follows

1. Voice Feedback - On/Off This feature allows the user to switch audible feedback on or off for most functions, with the exception of some necessary function which must have feedback to operate correctly.
2. Replay The replay command requests the voice recognition system to repeat the last dialogue response within a list in both audible and associated text feedback.
3. Notepad The notepad function allows the user to record a series of 10 notes for up to 5 minutes. The user can replay or delete the notes in the order in which they were recorded. It also allows the user to delete the entire contents of the notepad.
4. Traffic Message Channel (TMC) The TMC system is part of the navigation system (when fitted). The TMC system provides real time traffic information to the navigation system. The TMC voice commands can be used to switch the TMC On or Off.
