Global Positioning System Module: Service and Repair
COMMUNICATION INTERFACE MODULE REPLACEMENT
REMOVAL PROCEDURE
IMPORTANT: The vehicle communication interface module (VCIM) has a specific set of unique numbers that tie the module to each vehicle. These
numbers, the 10-digit station identification and the 11-digit electronic serial number, are used by the National Cellular Network and OnStar(R) to
identity the specific vehicle. Because these numbers are tied to the vehicle identification number of the vehicle, you must never exchange these parts
with those of another vehicle.
1. Remove the I/P center trim panel.
2. Remove the screws that hold the communication interface module to the I/P.
3. Disconnect the antenna and the electrical connections from the communication interface module.
4. Remove the communication interface module.
