Radio Theft Procedure
WARNING: This page is about a different car, the 2007 Pontiac Montana SV6, 2007 Chevrolet Uplander, and 2007 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
The radio theft will learn the VIN. Without learning the VIN, the radio will display a locked message (LOC or LOCKED).
If the radio is replaced, perform a VIN Relearn, located in the Module Setup section on the scan tool. Cycle the ignition when complete.
