Fiat 500 Radio Code: How to Retrieve Your Stereo Unlock Code

The Fiat 500 is an icon — and enormously popular in the UK. Beneath the retro styling is a very modern anti-theft system in the head unit. After a battery change or power interruption, CODE appears on the display. Here is how to retrieve your Fiat 500 radio code.

Head Unit Types in the Fiat 500

Fiat 500 (2007–2015): Bosch or Delphi Grundig radio
Fiat 500 (2015–2020 facelift): Continental or Uconnect 5"
Fiat 500 Abarth: Same radio systems as the standard 500

The all-electric Fiat 500e (2020+) uses a modern infotainment system without a traditional stereo code.

Finding the Serial Number

To retrieve the Fiat 500 radio code, you need the serial number from the head unit. Find it by:

Removing the radio using Fiat DIN release keys.
Locating the label on the casing.
Noting the serial number.

Frequently Asked Questions

Does the Fiat 500 Abarth have a different radio code?

No. The Abarth 500 uses the same radio systems. The code is linked to the serial number of the unit, not the model.

My Fiat 500 has a Uconnect system. Does that have a stereo code?

The Uconnect 5" system in later Fiat 500 models may have a stereo unlock code. The method is the same: find the serial number and retrieve the code.

Could the radio code be in the owner's handbook?

Sometimes the stereo code is printed on a separate card inside the owner's handbook or service book. Check there before removing the radio.
