REMOVAL PROCEDURE
1. Remove the center console, if equipped.
2. Remove the HVAC control.
3. Remove the communication interface module screws.
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
identify 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.
4. Disconnect the mobile telephone antenna cable from the communication interface module by pulling outward on the square plastic housing.
5. Disconnect the electrical connectors.
6. Disconnect the navigation antenna coaxial antenna cable from the module.
