Telephone Assembly, USA From 11/03/2008
The telephone system consists of the following components:
- Cell phone preparation (CAN)
The CAN bus connects the Telephone Transceiver -R36- to the Infotainment system (radio). It also has a Bluetooth Antenna -R152-.
Operation is performed via the Radio -R- or the Cellular Telephone -R54-.
The microphones for the Microphone Unit In Front Roof Module -R164- are integrated in the Front Interior Lamp -W1-. One microphone is connected (Left Front Microphone -R140-) with the Telephone Transceiver -R36-.
- Telephone Baseplate -R126- with Cellular Telephone -R54- (through MY 2008)
- Radio -R- in the Instrument Panel
- Sound Systems
- Bluetooth Antenna -R152- at Telephone Transceiver -R36-
- Telephone Transceiver -R36- under the Front Passenger Seat
- Microphone Unit in Front Roof Module -R164- in the Front Interior Lamp -W1-
- Radio/Telephone/Navigation System Antenna -R52-
- Cell phone preparation in the Information Electronics Control Module 1 -J794- (MMI)
The cell phone preparation does not have a separate control module (Telephone Transceiver -R36-), but rather all the functions are integrated into the Information Electronics Control Module 1 -J794-. The telephone is operated either by the Infotainment system MMI or by the Cellular Telephone -R54-.
The microphones for the Microphone Unit In Front Roof Module -R164- are integrated in the Front Interior Lamp -W1-. One microphone is directly connected to the Information Electronics Control Module 1 -J794-.

Notes on Bluetooth Technology
A standardized radio connection is used to transfer data between the Information Electronics Control Module 1 -J794- and Cellular Telephone -R54- - Bluetooth Technology.
An additional transmitter/receiver unit is installed in the Information Electronics Control Module 1 -J794-. A separate Bluetooth Antenna -R152- connects the Information Electronics Control Module 1 -J794- and Cellular Telephone -R54-.
The range of the radio connection is approximately 10 m.
