Metra's GMOS-01 interface lets you replace the factory radio in select
OnStar-equipped 2000-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.
Hook the GMOS-01 to your aftermarket radio, mount the module, and plug
it into the existing factory plug. Get the great sound you want, and
keep all important safety features intact. And you can adjust volume
settings for OnStar as well as the safety chimes. Also, once you turn
off the ignition in these GM vehicles, the radio continues to play until
you open the door. This interface maintains that function with your new
aftermarket radio.
This interface is compatible with select 2000-up GM vehicles. If you
haven't done so already, please enter your vehicle information or call
an Advisor at 1-800-297-9469 to find out if this item is compatible with
your vehicle. Warranty: 1 year.
