I think farsal confuses technilogical innovation with technical changes. I've been trying to figure out how to do what you're considering for a long time - and let me tell you that in terms of the 1991-93 systems they're certainly not "plug and play" compatable with the '94+ systems.
Some basic differences - in the older model the "head" unit is more of a "display" unit, with the tuner, amps etc. in the trunk, and the head unit acting like a remote control (& physical cassette tape player). The setup us entirely different in the 94+'s.
I'd do a search for this yourself, but the consensus seems to be that if you want to upgrade this system, start from scratch. Crutchfield, and some others sell/sold some conversion wiring for a 1991-93 190E, but it seems to be very MB model-specific (and out of stock).
I've come to the conclusion that (even installing a newer changer) jumping through all the hoops just to install an "old" technology isn't worth it, and I'd be better off to just figure out how to install a MP3 player, since I don't want to start over. First I'll have to get an MP3 player and hope that I can do it with copper!
Sorry, I haven't been pleased either.....Scott
