2 Y General description The radio/navigation system (RNS) combines the functions of a navigation system with that of a high quality RDS car radio. Vehicles >, a radio/navigation system is installed which includes a traffic information control unit. Apart from this the RNS unit > differs from the RNS unit > in the following ways: u On the top left of the unit front is the designation "Radio Navigation System", on an RNS unit > "FD" is additionally included. u There is also an additional aerial connection on the back of the unit. The units > and > are not interchangeable with one another. Installed in the systems double DIN housing are u a RDS radio receiver u a 5-inch liquid crystal colour display u a navigation system with GPS satellite receiver u a CD-RO drive for the navigation system. u A TV tuner is available as optional equipment for vehicles 01.01> with a radio/navigation system. The television function is an extended function of the navigation device. The device can receive all terrestrial programmes, that is, all programmes which can be received using a normal aerial, not via satellite. Workshop anual - 1 -

3 Y The device recognises all current broadcasting standards such as PAL, NTSC or Secam. The television picture is blacked out when the vehicle is in motion but the sound remains. A connector on the housing connects the radio, telephone and navigation operation aerial with the navigation system. Connections are provided to extend the radio functions for a 6 disc magazine CD changer and for a DSP sound system. Fault finding The radio/navigation system is equipped with self-diagnosis. To find faults, perform self-diagnosis with the vehicle diagnosis, testing and information system VAS => "Guided fault finding" on Vehicle Diagnosis, Testing and Information System VAS Workshop anual - 2 -

10 Y Removing and installing radio/navigation unit Notes: u The part number for the complete Radio navigation system is printed on a sticker on the radio/ navigation system housing! u If an RNS unit from a vehicle is fitted into a different vehicle, it is essential that the part number of the replacement unit is the same as the unit previously installed. Otherwise faults will occur with the navigation as the turn angle sensor adjustment in the RNS unit will not be compatible for the vehicle. Special tools, testers, measuring instruments and auxiliary items required u T10057 Release tool To remove the radio/navigation system, 2 sets of release tool T10057 are required. Removing: Note: Workshop anual - 1 -

11 Y u Before removing radio/navigation system, secure code number from the customer. If the radio/ navigation system is renewed, it is essential to activate the anti-theft coding (see operating instructions). The new code number must be given to the customer. u If the radio/navigation system has a TV function, carefully pull out the device to avoid damaging the RGB connection. If the RGB connection is damaged, the wiring connection must be renewed all the way to the TV tuner. Repair of the RGB connector is not possible. Carry out work sequence as follows: Ô - Slide radio release tool T10057 into the release slots -arrows- as shown until they locate. Top L - top and bottom on left Top R - top and bottom on right - Pull radio/navigation system out of the dash panel using the grip rings of the release tools. - Release connections and pull off Workshop anual - 2 -

12 Y Pulling out release tools: Ô - Press locking tabs -arrow- and pull release tool out forwards. Installing: - Connect plug to radio/navigation system. - Slide radio/navigation system straight into the dash panel, until it engages in the assembly frame. Note: u When pushing in the RNS device, do not, under any circumstances, press on the display or operating buttons, as this could damage the RNS device. u If the radio/navigation system is renewed, the proper broadcasting standard must be set for television reception. => Operating instructions, radio/navigation system/tv tuner Workshop anual - 3 -

20 Y Removing and installing TV aerial amplifier The four aerials (R55, R56, R57 and R58) for TV reception are integrated in the rear window of the. Each aerial has its own amplifier. The amplifiers (R82, R83, R84 and R85) are built into the tailgate/ boot lid of the. Removing: Remove tailgate trim. - Pull off aerial amplifier connectors. - Separate connector in wire between aerial amplifier and rear window, being especially careful, as the wire and the connector are very sensitive to mechanical stress. In the event of damage to the wiring connection between aerial amplifier and rear window, the rear window must be renewed. It is not possible to repair the wiring connection. - Remove aerial amplifier. If several aerial amplifiers must be removed, be sure to mark the fitting position of individual amplifiers. Installing: When installing, ensure that the amplifiers are fitted in the same positions from which they were removed. Installation is carried out in the reverse sequence! Workshop anual - 1 -

21 Y Checking function of individual TV aerial amplifiers Note: The test possibilities below describe only a simple test of the television system and are no substitute for testing with the vehicle diagnosis, testing and information system VAS You can have the performance of the individual TV aerials displayed on the television screen. Starting this function checks the basic functionality of the television system at the same time. The test screen is enabled in the following manner: - Switch on television mode and find a broadcaster with a strong signal. => Operating instructions - The test screen is activated by the simultaneous pressing of the "AS" button and the button with a clef symbol.

22 Y Screen display: ANT 1 = TV aerial 1 -R55- with ON and OFF function ANT 2 = TV aerial 2 TV -R56- with ON and OFF function ANT 3 = TV aerial 3 TV -R57- with ON and OFF function ANT 4 = TV aerial 4 TV -R58- with ON and OFF function Note: - The voltage supply of the respective TV aerial amplifier can be switched on or off using the right rotary control. When the voltage supply is switched off, the picture quality must become significantly worse. - Leave the menu by pressing the "Return" button. Possible tests: u The ability to switch the voltage supply of each aerial amplifier on and off makes it possible to draw a conclusion about the function of the respective aerial amplifier. u The operation of the TV tuner via the RNS partially tests the hardware and software of the CAN bus. u By readying the television system for operation, selecting a programme and selecting videotext, the most important functions of the television receiver have been used and the audio-video connection has been ensured. u Whether the cause of a fault is an interruption of the aerial cable or a defective TV aerial amplifier can be determined by more extensive fault finding.
