Not all navigation systems are plug & play!
General Motors (GM) automobile brands --Buick, Cadillac, Chevrolet, GMC --, Ford Motor Company & Lincoln Motor Company radio navigation systems require reprogramming before being used in a vehicle not originally installed in from the factory. The systems optimal functionality is determined by the VIN of the vehicle, which when searched produces the necessary RPO codes to program the radio navigation system with.
Common symptoms your radio needs to be reprogrammed are:
GPS does not track properly--lags behind current location
DVD movies will not play on factory rear entertainment system
Steering wheel controls will not function
No sound out of speakers
Turning the volume knob produces no response
