Radio Replacement
WARNING: This page is about a different car, the 2007 Hummer H2. 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.
