Are you sure that the code you have entered is correct? If you have entered the code more than 3 times incorrectly, it will refuse any code after that (even the correct code). In this case you will have to disconnect your battery to erase its memory of the wrong input(s) and try again. If that doesn't work, you will have to take your car to your Mercedes Dealer- they will have to pull the radio to get the serial number off of the back of the unit- then using that number they will be able to retrieve the actual code for you. (note: some dealers will charge you for labor if the radio does have to be pulled
