This service for FIAT cars is no longer available. As an alternative service we recommend Restored Classic: restoredclassic[at]aol.com

Labels applied to the case of the radio will often overlap the back and top, or top and side panels. Look to see if such a label is torn along the line where the panels meet; this might indicate the radio has been previously repaired and the code reset from the original on FIAT's database.

You will need to pull the radio from the dashboard to read the serial number from its chassis - this will be on a printed label, engraved on the metal case, or both. Most of the units fitted to Fiat are extracted using 'keys' - if this is the case with yours, you will see small slots each side of the faciaplate. Don't be tempted to try removing the radio another way or force it as you may damage the surrounding dashboard trim. The keys make it very easy - you can find them in motoring stores or online (most Fiat radios require the commonly used DIN type release keys shown here, but there are 2 or 3 different types so ensure you buy the correct ones).

Magnetti-Morelli Sat-Nav models fitted to Fiat cannot be decoded outside of the authorised Fiat service agents.
