Trying to help out a friend who has a E46 with BMW Navigation System with cassette player, one of the text type and some sort of player (not sure if it cd or dvd player, no mention of dvd on it) in the boot. She was thinking of buying a different headunit as they can't even listen to cd's in the car, a colleague has an ipod connector from his old E46 which she can have. what are her options? she doesn't want the navigation thing, is there anyway she can just unplug the older player in the boot and plug in a cd changer or connect the ipod adapter?
