I don't think you'll get one. The majority of Mercedes units use an
optical cable for CD changers e.t.c. and these haven't been developed

These 3 companies are the main ones for aux-in adators in the U.K. -
They may be able to help.

If you had an Audio 10 or 30, you could use this for normal CD:-
