Which number on the label should I enter?

The serial starting with AL, printed after S/NO. or stamped beside the label. Enter every character, including the letter in the middle. A Mercedes part number starting with A is not the serial.

Is MF2910 my serial number?

No. MF2910 is the model number. The code belongs to the AL serial of your radio, so we need that number.

When will I get the code?

If your serial is in our database, the code is sent by email right after payment. Otherwise our team reads it and emails it as soon as it is ready. If the code does not work with the serial you entered, you get 100% of your money back.

The radio needs a pause after incorrect attempts. Leave it switched on as instructed in its manual and wait until code entry is available. The wait depends on the model and the number of attempts.

Why your MF2910 asks for a code

The Alpine MF2910 is the Audio 10 CD radio that Mercedes-Benz fitted to many of its older models. Its anti-theft protection locks it whenever the power is cut, for example after a battery change or a repair, and it works again only after the code is entered.

Where to find the serial number

Switch off the ignition. Slide the radio out with removal keys, or remove the trim and mounting screws, depending on the car.
Look for S/NO. on the casing. The AL serial is printed on the label or stamped into the metal beside it.
Enter the whole serial, including the letter in the middle, e.g. AL2910X0505900. MF2910 next to Model No. is the model, not the serial.
