I have a 99 V70 with 3 disc in dash CD player and a connection to add a 6 CD Changer. I'd like to find out what the pin out is for that connector so I can hard wire my iPOD into that input. How do I get the head unit to activate that input without the changer being there, is there a way to fool it? If I push the 6 disc button nothing happens because nothing is connected. Anyone?
