Changed Battery. How to set radio codes?

4049 Views 4 Replies 5 Participants Last post by  UnlikeAnyOther

I recently changed the battery for my 1999 C230. After the battery change, my audio system will not play. The radio, whenever switched on, is asking for the code. I could not locate any radio codes in the owner's manual, or any other paperwork.

Can anyone please help me regarding this?

your choice is to ask the dealer for your Radio Code.

send me your vin number and i'll hook you up with the radio code.
I have the same problem with my ML430. I changed the battery and the radio wants the security code. I found the code card and entered the code, but the radio will not accept it. Now what?
If the code will not work, you need to remove the radio and have the dealer look up the code using the serial number. It sounds like your radio was replaced.
