This radio has new software installed that eliminates many of the issues addressed in this TIB A customer may complain about a range of symptoms in the navigation and audio system of the New Range Rover. Customers with Range Rover (LP) vehicles may in some cases experience similar navigation system faults. RESOLUTION: TROUBLESHOOT THE FAULTS AND RESOLVE Using the procedures in this TIB the following 2003 Range Rover audio and navigation complaints can be addressed: ^ Radio retunes itself to 87.7 at start-up ^ Navigation voice commands may sound distorted, or crackly and navigation system distance units appear in Miles/Yards rather than Miles/Feet ^ Navigation audio volume too low ^ Adjustment of speed dependent volume

Normal warranty policy and procedures apply. Material allowance is included in labor operation. REPAIR PROCEDURE NOTE: A new radio was introduced on 2003 Range Rover from VIN 3A This radio has new software installed, which increases the range of adjustment of the navigation audio volume. The new radio also includes the personalization feature "radio key memory". ^ If TestBook/T4 disk DJL0D07 or later is used to communicate with the vehicle, there should not be error messages from the radio during vehicle personalization. ^ If an older TestBook/T4 disk is used, error messages such as "the ECU configuration

3 Page 3 of 6 failed the following ECU: radio. The ECU has an obsolete coding index and must be renewed". The message indicates that during programming, the communication failed on the radio. ^ The new radio is configured correctly from the factory and therefore does not require personalization. This message can be ignored. PROCESS 1: PLACE "RADIO KEY MEMORY" FEATURE TO OFF SYMPTOM Radio autotunes to "87.7" NOTE: The "radio key memory" feature is not supported on early radios. If the option is enabled on these vehicles it will lead to the 87.7 tune problem. 1. If a customer complaint of "87.7" retuning at starting the car in the morning is confirmed, reprogram and disable the "radio key memory" feature as follows: ^ Connect TestBook/T4 to the vehicle. ^ Start the engine and turn on the headlights. NOTE: In the next step ignore Dimmer Potentiometer, and Xenon Headlamp LH and RH below 7.5V unless there is a problem with these systems. ^ Clear fault codes in vehicle ECU's. ^ Select "Vehicle Configuration" and then select "Personalization". ^ Go to the "Radio Key Memory" line item and switch it ON". NOTE: The saving of the settings in the next step will take a few minutes. ^ Press the "Continue" button to save the settings to the vehicle and wait for TestBook/T4 to complete the task. ^ Exit out of the testbook screens to the main screen. ^ Disconnect TestBook/T4 lead from the vehicle, and switch off the vehicle ignition. ^ Remove the key and wait one minute. ^ Connect TestBook/T4 to the vehicle. ^ Start the engine and turn on the headlights. ^ Select "Vehicle Configuration" then select "Personalization". ^ Go to the "Radio Key Memory" line item and switch it OFF. ^ Press the "Continue" button to save the settings a second time. This time the radio key memory feature is disabled. ^ Fully exit TestBook/T4 to the main screen, turn off lights and engine. PROCESS 2: CORRECT NAVIGATION VOICE/DISTANCE SELECTION TO "JAMES" CAUTION: Installation of a new navigation computer requires programming the new unit to the vehicle. Connect TestBook/T4 and select Diagnostics, Vehicle Information Systems, Vehicle Maintenance. Perform the ECU renewal procedure as you would on any other ECU on this vehicle. If you do not program the navigation computer in this way, it does not "learn" the vehicle specification or market.

4 Page 4 of 6 CAUTION: Two languages can be loaded into the navigation system at any time. The recommended navigation system voices for the US are "James" and "Spanish Female". The recommended navigation system voices for Canada are "James" and "French Female". You should never select both the Male AND Female selection of each language. I.e. never select "US English Male" and "US English Female" together as the system will not function correctly. NOTE: Land Rover has discovered a software bug when using the "UK English Male" voice option on the New Range Rover navigation system. The use of the "James" voice will give the same accent, but uses US terminology (for example: Freeway/Circle instead of Motorway/Roundabout) and James does not suffer from the distorted or clipped speech pattern. For detailed instructions on changing navigation languages see the Retailer PDI/personalization process on the InfoTrail SYMPTOM Commands sound distorted, or crackly. 1. If the navigation system "peaks" with a distorted voice or the ends of sentences are clipped or cutoff, change the voice in the navigation system to "James". NOTE: The change of units of measure is a customer requested adjustment. It is not a fault. SYMPTOM Navigation system distance units appear in miles/yards rather than miles/feet 2. If the navigation system states distance in Miles/Yards rather than the normal Miles/Feet, set the navigation voice to "James". The distance units will automatically change to Miles/Feet. PROCESS 3: CORRECT AUDIO VOLUME COMPLAINT SYMPTOM Navigation audio volume too low on 2003 Range Rover up to 3A If the navigation system volume is too low set radio audio systems for optimal performance as follows: ^ Press the left rotary knob to turn the radio on. ^ Press the "INFO" button. ^ Select "NAV-MIN" and use right rotary control to highlight "NAV-MIN+". ^ Press right rotary control as many times as necessary to obtain a setting of "+9" 2. Set navigation system for optimal performance as follows: NOTE: Setting volume to +10 or +12 will mute the radio entirely during a navigation audio command. Setting volume to +8 will give maximum navigation volume, but will mix the navigation and radio audio during a navigation voice command. ^ Press the "MENU" button on the MFD. ^ Select "On Road Navigation" and then "Information".

5 Page 5 of 6 ^ Select "Volume Navigation". ^ Set navigation volume to "+8". NOTE: The latest radio variant increases the range of adjustment of the navigation system voice commands volume significantly. PROCESS 4: ADJUSTING SPEED DEPENDENT VOLUME ON 2003 RANGE ROVER SYMPTOM Speed dependent volume too high or too low NOTE: "GAL" is an acronym derived from German representing "Speed Dependent Volume." A GAL setting of "1"is less sensitive and will increase the radio volume proportionally less as vehicle speed increases. A GAL setting of 6 is the most sensitive and will increase the volume the most. The factory setting is "2". 1. If the volume change is either too great or not enough when the vehicle speed changes, perform the following adjustment procedure to increase or decrease the sensitivity: ^ Verify that the power LED next to left rotary knob is NOT illuminated (the radio is off). ^ Press the left rotary knob to energize the radio. ^ Press and hold the "SELECT" button until the service mode is displayed. ^ Press and hold the "<>" button until the "GAL" display is visible. ^ Press the desired numbered button "1" through "6" to alter the GAL setting. Press the left rotary knob to turn off the radio. PROCESS 5: RADIO DISPLAY MODE SELECTION Zoom Sized for Print

6 Page 6 of 6 SYMPTOM: After a radio station is selected the Radio screen display disappears. 1. If the customer desires the radio screen display to remain revealed after station selection, the following steps will retain the display: ^ Press the left rotary knob to energize the radio. ^ Select the station of choice by search or by preset button ^ Press the RH side of the "MODE" rocker switch in the lower left of the Multi-Function Display panel. NOTE: The screen will toggle between the radio display and the menu screen. ^ Select the desired screen by pressing the MODE display symbol as required ALLDATA LLC. All rights reserved. Terms of Use
