Several radios are offered. The audio system uses a CAN B bus Ignition ON message so that the system will only operate when the ignition switch is in the RUN or ACCESSORY/ACCESSORY DELAY positions.
The audio system includes the following components:
- Amplifier

Certain functions and features of the audio/video system rely upon resources shared with other electronic modules in the vehicle over the CAN bus network. For diagnosis of the CAN bus network, the use of a scan tool and the proper Diagnostic Procedures information is recommended.
