Radio/Audio System Description and Operation: Notes
WARNING: This page is about a different car, the 2008 Chevrolet Malibu Classic. However, it is still accessible from the selected car via links, so may be relevant.
The entertainment system is configured with either a base or an uplevel system. Both the base and uplevel systems contain a radio, antenna, and speakers.
The uplevel system differs from the base level system by providing enhanced audio system features. These features may include the radio data system (RDS), and two additional speakers. The uplevel radio units are also OnStar® and XM Radio compatible.
The radio head includes the driver information display (DID). Driver information is provided to the radio head via GMLAN serial data link to the body control module (BCM).
