General

The unit contains a mobile phone as well as a GPS receiver and is connected to the radio, microphone, control panel, GPS/mobile phone antenna as well as data link connector via the car's wiring harness. The unit is equipped with a 12-pin and a 16-pin connector as well as an antenna connection.

The main functions of the system are as follows:


To communicate voice and data over the mobile phone network.

To receive data signals from the GPS and the calculation of the car's position. The position of the car is sent using data communication to the OnStar Call Center.

To send a bus message to activate the car's horn and hazard warning lights.

To receive bus messages when airbags are deployed in order to automatically phone for assistance.

To relay telephone conversations via the system speakers.

To switch off other sound from the audio system when making a telephone call. This is effected by feeding a "mute" signal from the OnStar unit to the audio unit which then disconnects the normal audio inputs to the speakers and the signal to any external amplifiers.

Diagnostic communication.
