Telephone connection

Telephone connection

General

The car is prepared for a mobile phone as follows:

•	Standard , standard provision, i.e., present in all cars.

•	Option , an option which means that the “handsfree” function can be used.

Standard

The car is prepared for the connection of a mobile phone with an 18-pin connector to which the phone is connected. The connector allows the audio system volume to be controlled (muted) and provides the phone with current (battery charging).

Cars as of model year 2001 and VIN 13047361 have an dummy antenna rather than an roof-mounted antenna. The dummy antenna looks the same as the previous antenna but has no connections.

Function

•	Voltage (+30) is supplied from fuse 8 to pin 11 for powering the mobile phone and charging its battery.

•	Voltage (+15) is supplied from fuse 21 to pin 10 for switching on the mobile phone.

•	Ground connection at grounding point G41P via pin 1.

•	Mute control for disconnecting normal sound via pin 4 of the 18-pin connector to pin 6 of the main unit.

Option (handsfree)

The car is prepared for the connection of a mobile phone with an 18-pin connector to which the phone is connected. This allows the “handsfree” function to be used.

The audio system's normal sound can be controlled (disconnected) and the power supply for the phone (battery charge) obtained via the connector. Incoming telephone sound is relayed through the audio system speakers and outgoing speech picked up by a built-in microphone in the car.

A coaxial cable is pre-routed and connected to the antenna on the roof.

Function

•	Voltage (+30) is supplied from fuse 8 to pin 11 for powering the mobile phone and charging its battery.

•	Voltage (+15) is supplied from fuse 21 to pin 10 for switching on the mobile phone.

•	Ground connection at grounding point G41P via pin 1.

•	Mute control for disconnecting normal sound via pin 4 of the 18-pin connector to pin 6 of the main unit.

•	Incoming phone sound (line output) via pins 7/16 to pins 22/23 on the main unit for relaying through the audio system loudspeakers.

•	Outgoing phone sound from microphone, signal via pin 18 and ground via pin 9.
