1996 A4 2.8: what radio for the trunk CD changer
 

I bought an A4 that has an aftermarket radio and the original trunk CD changer. I would rather have the OEM unit, but don't know what model to look for.

Can someone help me with specifying what model was in the are (or what OEM model can be used to control the trunk CD changer and fit into the dash)?

Maybe someone even has one laying around?

Thanks.
