Radio Replacement

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. 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 Special Functions section on the scan tool. Cycle the ignition when complete.
