connection between their cellular telephone and the Bluetooth

control unit. Hands-free cellular telephone

calls can be sent and received. Some Bluetooth

cellular telephones may not be recognized by the Bluetooth

control unit. When a cellular telephone or the Bluetooth

Steering Switches

When buttons on the steering switches are pushed, the resistance in steering wheel audio control switch cir-
cuit changes, depending on which button is pushed. The Bluetooth

• Initiate self-diagnosis of the Bluetooth

telephone system

• Start a voice recognition session

• Answer and end telephone calls

• Adjust the volume of calls

Microphone

The microphone is located in the roof console assembly. The microphone sends a signal to the Bluetooth

control unit. The microphone can be actively tested during self-diagnosis.

Audio Unit

The audio unit receives signals from the Bluetooth

control unit and sends audio signals to the Bose speaker

amp. The Bose speaker amp. then sends the audio signals to the speakers.

SPEED SENSITIVE VOLUME SYSTEM
