About the Metra GMRSAV Factory Integration Adapter
If you plan to install a new radio in your 2007-up GM vehicle and you want to retain the factory Rear Seat Entertainment system (RSE), Metra's GMRSAV adapter can help. This cable sends audio and video from your aftermarket radio to the overhead screen in your entertainment system. If you connect a secondary A/V source to the inputs on the rear seat control panel, it will route that signal to your new radio too. Warranty: 1 year.
