RADIO SYSTEMS

Radio Systems

1. "Chorus"
2. "Concert"
3. "Symphony"

Speaker Systems

1. Active speakers (rear speakers use Amplifier/Woofer (in left rear luggage compartment) -R44-).
2. BOSE sound

Radio Preparation

4 or 6 passive speakers and rear window antennas.

General Information

From KW 22/04, the "chorus" has a second antenna connection (IF).

Radio generation II+ introduced from KW 45/06.

This uses two internal tuners with "phase diversity" for reception.

Further removal steps are the same as with the "symphony" radio.

Besides switching diversity, "phase diversity" is the second procedure for reducing reception interference.

At least two antennas with an amplifier and a radio -R- with two tuners are required.

If the signal received is interrupted, both signals are digitalized and separated in the tuners in the radio so that the disrupted signals are blocked out as much as possible.

If the reception signal is not disrupted, the radio constantly compares which antenna has the strongest reception. This is then transferred.

In this case, the second tuner checks the frequency band in the background for better reception frequencies for the selected station. If a better signal is found, this tuner switches to reception and the other to the background.

Communication with other vehicle systems takes place via the Infotainment CAN-Bus and Data Bus On Board Diagnostic Interface -J533-.

Fault finding is performed via "Guided Fault Finding" using the Vehicle Diagnosis, Testing & Information SystemVAS5051.

Repairs on antenna wires, refer to ANTENNA WIRES, REPAIRING .

Repair to CAN bus lines, refer to CAN BUS WIRE, REPAIRING .

Transport Mode in "Symphony II+"

The "symphony" generation II+ has a special protection lock for the internal CD changer.

This is active when the unit is shifted and must be deactivated after installation.

In the same way, the transport protection must be activated before removing the unit.

Transportation mode, activating and deactivating, refer to RADIO, SYMPHONY II+ IN TRANSPORT MODE, ACTIVATING/DEACTIVATING .

TELEPHONE SYSTEM

Mobile Phone Prep

1. Telephone transceiver -R36
2. Antenna -R11- (Ter/Sat/GPS/GSM) roof antenna
3. Telephone baseplate -R126- with cellular phone -R54
4. Telephone Microphone -R38

The telephone transceiver is equipped with a Bluetooth Antenna -R152-. Using this, all cellular phones approved by Audi can be operated with the Bluetooth interface with the cell phone preparation installed in the vehicle.

It is not possible to connect other devices via Bluetooth, for example headset, laptop, PDA, or similar.

Cell Phone Preparation Preliminary Setup

1. Black 18-pin connector behind the glove compartment.
2. Antenna (Ter/Sat/GPS/GSM) roof antenna.
3. Telephone microphone

Fault finding is performed via "Guided Fault Finding" using the Vehicle Diagnosis, Testing & Information SystemVAS5051.

Repair to CAN bus lines, refer to CAN BUS WIRE, REPAIRING .

NAVIGATION SYSTEM

Description

RNS-E navigation system is an enhancement of the established navigation system II-D. The function selection switch is integrated in the unit (MMI operation). A DVD is used as the navigation CD.

Screen folds away. DVD drive and two MP3 card readers are located behind.

In addition to the navigation system, the RNS-E has a radio, two MP3 card readers and connections for Navigation/TV Tuner -J415- and CD Changer -R41-. The DVD drive can play music CDs.

Fault finding is performed via "Guided Fault Finding" using the Vehicle Diagnosis, Testing & Information SystemVAS5051.

Repairs on antenna wires, refer to ANTENNA WIRES, REPAIRING .

Repair to CAN bus lines, refer to CAN BUS WIRE, REPAIRING .

STEERING COLUMN ELECTRONIC SYSTEMS CONTROL MODULE

Description

The steering column electronic systems control module -J527- is a part of the steering column switch module. The steering column switch module consists of

1. Left and right steering column switch
2. Airbag spiral spring
3. Steering Angle Sensor -G85
4. Ignition/Starter Switch -D
5. Steering column electronic systems control module

The steering column electronic systems control module exchanges data between vehicle control modules (e.g. Vehicle Electrical System Control Module -J519-) and steering column modules (e.g. steering column switch) and steering wheel modules (e.g. airbag).

In addition, multi-function steering wheel button signals are process and relayed via CAN BUS.

Fault finding is performed via "Guided Fault Finding" using the Vehicle Diagnosis, Testing & Information System VAS5051.

Steering column switch module, removing and installing, refer to [For engine(s) CBRA, BPY, CCTA, CBFA] Removal and Installation .

Repair to CAN bus lines, refer to CAN BUS WIRE, REPAIRING .

MULTIFUNCTION STEERING WHEEL

Description

Buttons are integrated in the steering wheel for easier operation of the radio -R-, cellular telephone -R54-, navigation and CD changer -R41-.

With Tiptronic (automatic transmission), additional switches are installed.

The electronics integrated in the steering wheel take over signal processing from the buttons and transfer signals via the LIN data bus (single wire bus) to the steering column electronics control module -J527-. The conversion to CAN BUS (comfort) takes place there.

The multi-function steering wheel is part of the complete steering column switch module (SMLS) system and delivers data via the LIN data bus to the steering column electronics control module.

The individual button blocks and the Tiptronic switch can be replaced separately.

The electronics inside the steering wheel cannot be replaced individually. If faulty, the entire steering wheel must be replaced.

Fault finding is performed via "Guided Fault Finding" using the Vehicle Diagnosis, Testing & Information SystemVAS5051.

Repair to CAN bus lines, refer to CAN BUS WIRE, REPAIRING .

SATELLITE RADIO, ACTIVATING

When using for first time or when replacing satellite radio -R146- tuner, it must be enabled (activated) by the provider (XM or Sirius).

The subscription and application for activation can coincide with submission of all necessary data (US postal address, credit card number, radio ID (XM) or SID (Sirius)) to the provider's call center.

Only SIRIUS

SIRIUS sends the activation sequence 6 times within the first hour after apply for the activation. If no successful activation results, another activation sequence must be requested at the SIRIUS call center.

Requirements

1. Customer has subscribed to XM or Sirius.
2. Satellite radio is installed and connected.
3. The radio -R- /operating electronics/navigation system control module -J402- is adapted/coded.
4. Ignition switched on.

Procedure

Turn on the radio/operating electronics/navigation system control module and select a satellite radio -R146- reception range.

Attempt to receive "free" channels in XM (e.g. channel 1) or Sirius band (only channel 184).

Change location if necessary.

If free channels can be received clearly, the activation information sent by the provider (XM or Sirius) can also be received clearly.

A poor reception situation can prevent a successful activation even though activation information is being broadcast. In this case, vehicle location must be changed (an activation is also possible while vehicle is moving). There are e.g. workshops, garages, parking buildings, underground garages, fuel filling stations with extensive roofs and all other parking areas with signal shadows must be avoided.

In built-up areas with terrestrial radio system coverage (so-called terrestrial repeaters) as well as inner cities, activation via a repeater is possible instead of satellite.
