Ive got a Sony CDX-M600R head unit and am looking to fit a cd changer that will go with it.

Can you use pretty much use any sony changer with this head unit or does it have to be a certain range of models that sony did a couple of years ago?

 

Virtually any Sony CD changer will be fine.

 

The 10 disc changers are a bit on the hefty side, 6 disc changers are a lot easier to find a home for. and will fit under front seats (on a classic anyway).
