Mercedes Benz repair: radio codes, radio book, radio code

Question
i need the radio codes for my 1997 s420

Answer
Greetings!
  The radio code should be located in your owners manual,First, find the radio book and you should have it in there. If not, you will have to call your local dealer and may have to even go down there to prove that you are the owner of the car. Thanks and i hope this helps
