How to Find your Mercedes Radio Code

It is quite simple to remove your Alpine radio. You will need a set of radio release keys (PC5-132). These are inexpensive and are around £3 – £5, you can obtain them from a local car audio shop or Online.

Once you have the radio release keys, push them into the 2 holes in each bottom corner of the radio (See image), apply a little pressure and the radio will release from the dashboard. The radios label is located on the radio’s casing.
