Product Purpose

The Crux SOCGM-18 is a radio replacement interface for select General Motors vehicles built between 2006 and 2017. It allows owners to install an aftermarket head unit while keeping the factory safety and warning chimes active. The module is designed for vehicles using the LAN 29-bit data protocol.

Deciding Specification

The interface works only with compatible Buick, Cadillac, Chevrolet, GMC, Hummer, Pontiac, Saturn and Suzuki models that use the LAN 29-bit system. It supports Bose, non-Bose and Y-91 audio configurations. Vehicles outside the listed model years or those using a different data bus will not function with this part.

Installation Notes

The unit provides a 12-volt accessory output, retained accessory power, illumination output and a telephone mute trigger. Chime volume is adjustable on the module. Installers must verify the specific vehicle application against the compatibility list before wiring, as incorrect vehicle selection is the most common cause of failure.
