VW/Audi Concert (etc.) Arduino CD Changer Emulator

My long-time faithful automotive companion, the 1982 300SD, is on its way out as a 1998 A8 Quattro comes in. It's just old enough (and low-spec enough) to have come with an ordinary radio instead of a LCD navigation unit. Unlike the 1997 which became the parts car when I got this car, the CD changer at least speaks an ordinary and boring protocol and it can be emulated away for those who would like a line input instead.
