My wife has a 2005 Trailblazer. The stock HU doesn't have controls for XM or a CD changer. Is there anyway that I can get an adapter that has a USB or headphone hook up to play either of these in the truck? I'm not looking to control it with the radio, just play.
If not will a newer stock HU plug right in?
