Crux SOCGM-17C Radio Replacement Interface with Chime for GM Class II Bose Amplified & Non Amplified Systems

The CRUX SOCGM17C Radio Replacement Interface is a dedicated wiring module designed to make upgrading to an aftermarket car stereo easy in select General Motors Class II databus vehicles (2000–2013). This interface retains important factory features that would otherwise be lost when replacing the OEM radio — including vehicle safety and warning chimes (such as seat belt, check engine, key-in-ignition, low fuel, low oil, and lights on) and retained accessory power (RAP). It supports both factory-amplified (Bose/Monsoon/Y-91) and non-amplified audio systems, with a built-in audio level adapter to properly match aftermarket head units to the factory amplifier if present.
