I have a 2005 montana sv6 that the radio went out in. my wife would like a new head units so she can plug in her ipod too but we have the factory DVD player too. are there any option here? I can find the adapter that retains door chimes and such for the radio but i dont see anyway to hookup the dvd player. is there a wiring diagram somewhere? I only need to power the dvd player up and send audio through the speakers through an aux port but i dont know the wires.
