The audio system operates on a non-switched fused B(+) battery current source and is turned ON or OFF by electronic messages received over the Controller Area Network (CAN) data bus. The system will only operate when the status of the ignition switch is RUN or Accessory.

The radios can be identified by their sales code. An optional navigation radio is available on this vehicle; for more information, see. Refer to NAVIGATION/TELECOMMUNICATION, DESCRIPTION .

All of the radios have an integrated Hands Free Module (HFM). There is no external HFM because all hands-free functions are integrated into the radio.

The audio system includes the following components:

• Antenna and Antenna Module, if equipped, (radio, satellite, GPS, cellular). Refer to ANTENNA, SATELLITE, AUDIO, DESCRIPTION  or ANTENNA, SATELLITE, AUDIO, DESCRIPTION  or MODULE, DIGITAL AUDIO BROADCASTING ANTENNA, DESCRIPTION .

Certain functions and features of the audio system rely upon resources shared with other electronic modules in the vehicle over the Controller Area Network - Interior High Speed (CAN-IHS) data bus. The data bus allows the sharing of various kinds of information. To diagnosis these electronic modules or the CAN data bus, the use of a scan tool and the proper diagnostic procedure information is recommended.
