About: PAC LCGM24 Radio Replacement Interface for Select GM Vehicles

The entry-model LCGM24 provides a warning chime retention with an onboard buzzer and 12v ACC output. It does not provide navigation outputs such as VSS, Reverse Output, or Parking Brake Outputs; please see the GM1A-R for a full-featured solution. Does not retain OnStar®. Please see OS-2X for an OnStar® solution.

The LCGM24 allows the replacement of a factory radio in select General Motors vehicles with Class II radios. Using this interface will retain factory features such as warning chimes, factory amplifier, and provides a data-bus generated 12-volt retained accessory power output (RAP). RAP keeps the radio powered after key-off, just like the factory system. The LCGM24 also issues data commands that maintain a “healthy” system status to other vehicle systems.
