CD Changer interface/protocol

[Speedy]

I am looking for any and all info on interface protocols for car head
unit CD changer control. I have a new Blaupunkt head unit, so this would be
preferred but any info would be helpful. I have designed a MP3 player, and
even a user interface, but CD changer option would be excellent. I believe
the Blaupunkt uses the Philips D2B interface, is this true? Thanks in
advance!

All these are incomplete, but you might find some useful info :

This one uses DMS (I think that's blaupunkt)

I my self is looking into this right now. I have bougt me an older
Blaupunkt changer (CDC A05) and in the near future im going to try
figure out the protocol. I think Blaupunkt is using a bus interface
called CAN-bus developed by Bosch (ISO 11898). Try to look into this
integrated circuit PCA82C250. Im in the early stages of these matters so
this is without 100% certainty.

btw... my headunit is a Blaupunkt Acapulco (RDM168)
