General information

General information

The components of the systems Radio R / Telephone Transceiver R36 / Navigation System with CD Drive Control Module J401 / Speech Input Control Module J507 / TV Tuner R78 / Chip Card Reader Control Module J676 / Media Player, Position 1 R118 / Media Player, Position 2 R119 / Digital Sound System Control Module J525 / Data Bus On Board Diagnostic Interface J533 are combined with one another in a "ring". This "ring" represents the optical MOST-Bus.

The connection to the other BUS systems in the vehicle are provided by the Data Bus On Board Diagnostic Interface J533.

The "central control module" is the Front Information Display Control Head Control Module J523. The transfer of signals representing the instrument cluster display occurs via the MOST-Bus to Data Bus On Board Diagnostic Interface J533 and from there via CAN-Bus (instrument cluster) to the instrument cluster.

Scheme 1

Fault finding is performed via "Guided Fault Finding" using.

Additional information 286New Data Bus Systems - LIN, MOST Bluetooth , 293Audi A8 Infotainment.

Information on optical MOST-Bus

In addition to the CAN-Bus systems, an optical data bus system has been implemented.

Data exchange of the systems Radio R / Digital Sound System Control Module J525 / TV Tuner R78 / Media Player, Position 1 R118 / Media Player, Position 2 R119 / Telephone Transceiver R36 , Navigation System with CD Drive Control Module J401 / Chip Card Reader Control Module J676 / Data Bus On Board Diagnostic Interface J533 occurs via the MOST-Bus.

A fiber optic cable is utilized as the "connecting cable".

Fiber optic cables are routed inside corrugated tubes for protection.

Ensure that harness connector end faces are not soiled.

Scheme 2

If harness connectors are disconnected: Install Protective Cap For Cable Connector VAS 6223/9 - 1 -.

Fiber optic cables cannot be repaired, they must be replaced completely.

Observe the minimum bending radius of 25 mm when routing fiber optic cables. Fiber optic cables must not be pinched or bent.

Repairs on fiber optic cables --> 97 - WIRING .

General information

The telephone system consists of the versions

1. Telephone fixed installation

Telephone Transceiver R36 is incorporated into the MMI Infotainment system via the MOST-Bus.

The Telephone Base plate R126 for SIM card and for wireless Telephone Handset R37 (Bluetooth technology) is located in the center console/center armrest. Operation is performed via Multimedia Control Head E380 or via Telephone Handset R37.

Microphones for the Microphone Unit (in front roof module) R164 are integrated in the Front Interior Light W1. Of these, one microphone is connected to Telephone Transceiver R36.

1. Cellular telephone preparation

Telephone Transceiver R36 is incorporated into the MMI Infotainment system via the MOST-Bus. In addition, a Bluetooth Antenna R152 is available.

The Telephone Base plate R126 is installed in the center console/center armrest. Operation is performed via Multimedia Control Head E380 or via Cellular Telephone R54.

Two microphones for the Microphone Unit (in front roof module) R164 are integrated in the Front Interior Light W1. Of these, one microphone is connected to Telephone Transceiver R36.

1. Bluetooth car telephone

The Bluetooth car telephone is also equipped with operation for the Bluetooth cellular phone. The Bluetooth cellular telephone must not be incorporated into a base plate and not into the vehicle handsfree equipment.

Incorporation occurs exclusively via the Bluetooth connection. In this way, the SIM card of the cellular telephone (phone book) can also be read out.

The Bluetooth car telephone possesses its own handset (Bluetooth handset) with SIM card insert slot and charge cradle.

The Bluetooth car telephone and cellular phone can be operated via the Bluetooth handset, the handsfree equipment in the multi-function steering wheel and via the speech dialogue system.

With the cellular phone preparation and the Bluetooth car telephone, all Audi-approved Cellular Telephones R54 with Bluetooth interface can be operated.

Information on operation and approved cellular phone types

1. www.audi.de/telefon

1. Cell phone preparation preliminary setup

The preliminary setup connector is located in the center console. The Microphone Unit (in front roof module) R164 is integrated in the Front Interior Light W1.

A microphone is connected to the connector.

The Radio, Telephone, Navigation System Antenna R52 antenna connector is located on the connector.

Fault finding is performed via "Guided Fault Finding" using.

Repairs on antenna wires --> 97 - WIRING .

Information on Bluetooth technology

Bluetooth technology is a radio communication standard used for transferring data between Telephone Transceiver R36 and Telephone Handset R37 / Cellular Telephone R54.

An additional telephone transceiver is located in the Telephone Transceiver R36. A separate Bluetooth Antenna R152 connects Telephone Transceiver R36 and Telephone Base plate R126 / Cellular Telephone R54 so that Telephone Handset R37 / Cellular Telephone R54 can be operated wirelessly, thus without a wire connection.

Signal range of radio connection is approx. 10 m.

For more information, refer to 286New data bus systems - LIN, MOST, Bluetooth.

The Microphone Unit (in front roof module) R164 in the Front Interior Light W1 consists of a maximum of three microphones.

As of calendar week 22/04, only two microphones were installed.

For this, one microphone is connected directly to Telephone Transceiver R36. The other microphones are connected to the Digital Sound System Control Module J525.

The Audi-Motorola Digital telephone is available as an option and works in conjunction with the Telematics system. The Telephone/Telematics system is linked to the Communication system via the CAN-Bus to the Data Bus On Board Diagnostic Interface J533.

The base plate/cradle for the telephone handset ( Telephone Base plate R126 ) is located in the center console. When the telephone handset is removed from the base plate, it functions as a normal cellular telephone, i.e. no interaction with vehicle systems (Telematics, MMI or other) is possible.

When the telephone handset is docked, telephone functions are performed either with the telephone handset or Multimedia Control Head E380. Information is displayed on either of the two Multimedia Interface (MMI) displays.

Two microphones in Microphone Unit (in front roof module) R164 that support the voice recognition system are integrated in the front roof module ( Front Interior Light W1 ).

Before troubleshooting or servicing, technicians must be familiar with the functions and operation specifics of the Telephone/Telematic System. Always read the Telephone/Telematic system owners manual and review applicable system functions.
