have a 04 escalade with bose, nav, onstar and cd changer ect. thinking about installing my pioneer avic d3. searched on crutchfield, but they no longer sell the avic d3, so i cant figure out what harnesses ect im going to need for the install. does anyone know which gmos harness is needed? also, what else do i need to retain the factory door chimes, and steering wheel controls? also, i heard you need some kind of harness or adapter to be able to use the pioneer with the bose speakers? any information is appreciated
