Axxess GMOS-LAN-03 LAN OnStar Interface for Non-Amplified Systems
The Axxess GMOS-LAN-03 wiring interface lets you replace the factory radio in select OnStar-equipped 2006-up GM vehicles using the existing wiring and connectors. Even if you don't subscribe to OnStar, you'll need this interface to connect an aftermarket stereo. Connect the GMOS-LAN-03 to your aftermarket radio, mount the module, and plug it into the existing factory plug. Get the great sound you want, and keep all of the important safety features intact. You can adjust volume settings for OnStar as well as the safety chimes. In addition, this interface lets your new receiver work with any existing factory amplifiers. This interface gives you convenient plug-in connections for the Axxess steering wheel control adapter (not included) that works with most aftermarket stereos -that means less wiring work for you. This interface even includes a relay that enables you to keep the audible "click" for your vehicle's turn signal.
