Radio Messages

Calibration Error: The audio system has been calibrated for the vehicle from the factory.

If Calibration Error displays, it means that the radio has not been configured properly for the vehicle and it must be returned to your dealer for service.

Locked or Loc: One of these messages will display when the THEFTLOCK® system has locked up the radio. Take the vehicle to your dealer for service.

If any error occurs repeatedly or if an error cannot be corrected, contact your dealer.
