Hi, I have a 1999 CLK 320. I disconnected the battery to clean off the terminals and now it wants a code for the stereo to work again. Can anybody help me here? I have no idea what to do next.
Thank you very much.

Welcome to the forum

Check your owner's manual set for a separate piece of paper with a code.

If you don't have one, see - it's a "sticky" at the top of this forum page, placed there so it is easy to find.

If you experience problems actually entering the code, your radio manual should also tell you how to enter it. Alternately, see post #2 at, or - or search the forum for code entry. Different radios have different ways of entering the code.
