CRUX Wiring Interface

Crux's CS-GM43 wiring interface lets you install a new radio in select 2019-up GM vehicles while retaining many of your vehicle's important features. You'll be able to keep your steering wheel audio controls as well as your warning chimes, retained accessory power (R.A.P.), and backup camera (in select models). The interface module also provides 12V accessory, illumination, and reverse outputs. The package includes two wiring harnesses to connect your new radio to the factory wiring and two steering wheel control harnesses for different brands of aftermarket stereos. This interface is designed for vehicles that will have the factory amp bypassed or have unamplified systems. Note: does not retain Bose factory amp or OnStar. Please contact an Advisor at 1-888-955-6000 to see if the CS-GM43 interface is compatible with your vehicle.
