How do I find my car radio serial number?

The serial number is printed on a sticker on the side, top, or back of your car radio unit. You may need to remove the radio from the dashboard to see it. For many radios, the serial starts with a letter (M, V, L, or C) followed by 6 digits, or it is a 7-digit PCB number.

How do I enter the unlock code on my radio?

After receiving your 4-digit code, use the preset buttons (1–4) on your car radio to enter each digit. Press button 1 repeatedly until the first digit matches, then button 2 for the second digit, and so on. Finally, press and hold button 5 or the confirmation button to submit.

What if the code doesn't work?

Double-check that you entered the correct serial number. Make sure there are no typos and that you are using the right prefix letter. If the code still doesn't work, your radio may require professional service.
