Metra's GMOS-100 adapter allows you to retain the factory satellite radio tuner when you install a new car stereo in select General Motors vehicles. Their 99-3010S adapter package allows you to do the same thing with 2010-up Chevy Camaros. If your vehicle doesn't have GM's Driver Information Center and satellite radio information displays on your factory radio's screen, you'll lose that display when you install a new car stereo.
You can solve that problem with this XIA-LCD LCD screen, which attaches easily to your dash with four adhesive strips. Once connected, you'll see all satellite radio station, artist, and song info on its 2-line display, while the "Up" and "Down" buttons allow you to move from station to station. You'll also see iPod info on the screen if your iPod's connected to the GM factory input, and the "ENT" and "ESC" button help you navigate your playlists.
