Product Identity

The PAC LCGM24 is a radio replacement interface designed for select non-amplified Class II GM vehicles. It uses a 24-pin connector to link an aftermarket head unit with the factory wiring harness. The module retains all original safety warning chimes and supplies a 10-minute retained accessory power output after the ignition is switched off. Firmware updates can be applied through the PAC-UP USB adapter when required.

Fitment Guidance

This interface suits installers replacing the factory radio in compatible non-amplified Class II GM vehicles while keeping chimes and RAP functionality. It is not intended for vehicles equipped with factory amplified audio systems or those using a different data-bus architecture. Buyers who need integration with an amplified system or a non-Class-II platform should look at a different interface.

Sustained Operation

During continuous use the module maintains chime playback and accessory power timing without interruption. The retained accessory output stays active for the full 10-minute period after key-off, then shuts down cleanly to protect the vehicle battery. No thermal throttling or signal degradation occurs during extended driving sessions.
