Data Interface - GM 2016-2021

The AXGM data interface is engineered to retain OnStar® functionality and restore factory warning chimes when replacing the original radio. It also provides a 12-volt, 10-amp accessory output for powering an aftermarket navigation radio. Designed for select non-amplified GM vehicles, this interface includes a vehicle-specific harness for streamlined installation. Because compatibility varies by application, refer to the Vehicle Fit Guide to confirm whether an AXGM integration solution is available for your vehicle.
