Will a Becker cassette radio from a '95 S Class fit in an ML? Apart from fiber optics, if the ML has it, is the wiring harness the same?
Does the ML use the ISO plug? Will it fit in the hole? What else should I know? Thanks a bunch.

The 95 S class has a DIN size radio, the 98-99 ML also is a DIN size. 2000 and new MSC units are double-DIN size, so if you have a 2000 or newer ML, it would need an adapter of some sort to fit the S class radio, usually a DIN-sized storage box is used in factory applications.
I think it would fit OK into a 98-99, but I'm afraid the wiring would be too different to make it a worthwhile swap (not worth the effort IMO).
