Axxess GMOS-LAN-08 OnStar Interface for 2012 - 2016 Cadillac, Chevrolet and GMC Vehicles

The GMOS-LAN-08 interface is designed to allow you to install an aftermarket radio and have it interface with the OEM vehicle and OnStar system. The GMOS-LAN-08 is designed for 2012 - 2016 Cadillac, Chevrolet and GMC vehicles that use the GMLAN data bus system. The interface retains full functionality of the OnStar system as well as all safety and warning chimes.

This interface has the capability of adjusting chime and OnStar volumes as well. In addition to these features, the GMOS-LAN-08 now has the required outputs for the installation of a navigation radio.
