I don't believe an 85 needs a code, 1990 was the first year for an actual numbered code for an MB.
There was about 2 or 3 years, I know it was later than 85, where if the radio were disconnected from a power source too long, it had dashed lines across the radio faceplate. The dealer needs to reset this with a special tool. If your radio is inoperative, it needs to be diagnosed, may just be a fuse is blown, could be lots of different things.
