The 140 car is set up to work with a becker 980 10 cd changer that is out of production. There is a way to add an alpine m-bus 6 cd changer to the factory system controlled through the stock radio. The plug in is at the tuner box(1532) in the trunk behind the left side trim panel. It requires three cables from PIE a translator box from mbz and an alpine cmh-s620 cd changer.
