Stoned 06, Not butting at all, We need all of the information we can get. Look up P.I.E. They have adaptors but they say they will not work if there is a factory DVD in the backseat but they will work if there are back seat stereo controls. Unless the Backseat DVD is using the Satellite button (switch) at the head unit I think that it still can be done but so far I have not found enough information to make a Aux in device to operate using that switch. P.I.E. devices sell for around $65 + installation if you don't want to do it yourself. I got a phone estimate the other day and they wanted about $250 for the device and installtion, but would sell me an aftermarket unit with GPS, MP3, phone and aux in capabilities for about $250 + installation. I realize these guys need to make a living, but being retired in this economy, I need to eat.
