93 mercedes

Can anyone give me the procedure for coding the stock radio in a 1993 Mercedes C280. I've got the code but dont know the procedure for entering it into the radio Local dealership wont tell me the procedure to do this. Any help would be appreciated.

Wow that's kind of messed up they won't even tell you the procedure.... ANYWAYS, usually it's pretty simple just enter the code and it will beep or just start operating normally.  Most of the time they will tell you how to do it in your owner's manual.  Unfortunately, some radios have a lockout feature where if you enter in an invalid code a certain number of times (sometimes within a certain time period) it will eventually just lock up and you have to take it in to the dealer to have them reset it.  Others only lock up for like an hour or two.  But hopefully yours hasn't locked up yet.
