Mercedes-Benz E-Class Radio Code

Every Mercedes-Benz E-Class from 1995 to 2009: which radio was fitted, where its serial number hides, and what we can do with it.

Your code comes from the serial number of the radio, not from the car — so the first job is getting that number off the unit. The table below is your E-Class, generation by generation.

Already have the serial? Type it in and we will tell you straight away whether we can answer it.

Count the numbered station buttons. The code is typed on them, so a four-button radio can only take a code made of the digits 1–4.
That does not look like a Mercedes-Benz serial — check the table below for where to find it.
We never ask for the code you are missing — only the serial.

Radio names are what is written on the fascia, not the name of the company that built the unit — a “6000 CD” or an “RCD 300” is what you see in the car. Unit fitment varies by market and trim, so treat the list as the usual case and let the serial decide: it is the serial that determines the code, not the model.

How to enter the code in your E-Class

  1. Switch the radio on — the display asks for CODE.
  2. Each preset button enters its own digit: button 1 types a 1, button 2 a 2, and so on. A four-button radio therefore only takes codes made of the digits 1–4.
  3. Press the buttons in the order of your code, then confirm — usually by holding the rightmost preset or pressing OK.
  4. Your code email spells out the steps for your exact unit.

Careful: most units lock for good after about ten wrong attempts. If a code does not take, stop and email us before trying again.
