Just bought an A3 that has the concert system in it. I really want to play my iPod through it so was wondering if changing the head unit is the way to go. It must look original, be simple to operate and sound good. I already have a Parrot system in the car for the phone so that side of it is not important. If changing the head unit is not the way to go, what should I do? Money is not really the overiding factor.
