Description

The Metra Axxess GMOS-LAN-01 is a wiring interface designed for replacing the factory radio in select GM vehicles. It allows for the installation of an aftermarket receiver in non-amplified systems utilizing the GMLAN Data Bus. The interface retains the full functionality of the OnStar system, as well as warning and safety chimes with adjustable output levels. It also maintains balance and fade settings and retains the Retained Accessory Power (RAP) features.
