For 2008 and later models, the radio consists of the Front Radio Control Module (FRCM) located in the center trim panel, while the radio itself is a separate component behind the FRCM. If replacement is necessary, it must be done by a dealer service department due to required module configuration programming.

The theft deterrent system, known as GM's "TheftLock," activates when the radio or battery is disconnected. It displays "LOC" to indicate power removal and requires a secret code for reactivation, which can be personal or obtained from the dealership if lost.
