I did a search here and did find what I was looking for so, here it goes. I did the Scion radio swap in my Taco and a coworker has a 04 Runner and wanted to do the same his question was he has the rear radio control's will they work if he does the swap? Also he asked about the surround sound setting's if he would lose that. Thank's for all the usefull info that I have found here It has gave me some new Idea's on how to hook up my Ipod.
