Count the preset buttons

Most Becker and Blaupunkt radios in older Mercedes cars enter the code by pressing the station buttons, so a radio with 6 preset buttons can only have code digits from 1 to 6. Count the numbered buttons on the front of your radio and choose the calculator with the same number. If a code is rejected, check that you picked the right number of buttons before trying again.

Entering the code

On Becker radios, each preset button usually stands for one digit value: press the buttons in the order of the code digits (for code 3142, press 3, 1, 4, 2) and confirm as described in your manual. Other units are covered in how to enter a radio code.

Frequently asked questions

Why do I have to choose the number of preset buttons?

Becker and Blaupunkt Mercedes radios type the code with the preset buttons, so every digit of the code is between 1 and the number of buttons. The calculator needs to know whether your radio has 4, 5, 6, 7, 8 or 9 presets.

How do I get the code for Mercedes Audio 10?

Audio 10 radios made by Alpine (MF2910, MF2199) are looked up by the 14-character serial starting with AL, or by the car's 17-character VIN.

Does this work for COMAND or NTG units?

No. COMAND and newer NTG head units do not use these codes. Use the request form for other Mercedes radios.
