Security code reset after buying used 2005 Mercedes M Class

Asked by Mar 26, 2017 at 04:27 PM about the 2005 Mercedes-Benz M-Class

Question type: Car Customization

I bought a used Mercedes and cannot access the Radio/Navigation system as it is asking for a 5-digit security code and I am unable to find it in any of the manuals.  How do I get the code so I can use the radio/navigation system/CD, etc.?

You'll need to visit your local Mercedes Benz Dealer with your vehicle identification number (VIN) and proof of ownership (your driver's license and the vehicle registration). HTH. -Jim
