i know sattelite radio makes a thing where you take over a certain station which for me is 88.7 and you can play an mp3 player through with the 3.5 mm jack they provide. and i remember seeing one from pep boys where as long as you dont have the 6cd changer unit, u could use that one. If you want the exact name of the sattelite radio one, please let me know and ill look it up for you
