Insert radio release keys into the four pinholes at each corner of the fascia and apply gentle outward pressure. The unit slides forward. You do not need to disconnect any wires.

The serial number is on the sticker label on the back or side of the unit casing. It starts with BP followed by 12 to 14 digits, for example BP62034596031.

The serial number is on the label on the back of the unit casing. It starts with A2C followed by digits, for example A2C53387511. This is the most common type on C3, C4, C5, Berlingo, Dispatch and Picasso models (2004 to 2015).

The Becker RNEG is the factory navigation head unit fitted to C4 and C5 models with built-in sat nav (approximately 2008 to 2014). It has Harman/Becker Automotive Systems printed on the label and carries both the Citroën and Peugeot logos.

Remove the unit using a pry tool and screwdriver to release the surrounding trim. The label on the back shows a Model No. (e.g. BE 6450) and a separate Serial No.. this is a single letter followed by 7 digits, for example A5180162. Enter the serial number only, not the model number.

FAQ

Frequently asked questions

Why does my Citroën radio ask for a code?
Citroën radios have a factory security lock that activates when the power supply is interrupted, for example after a flat battery, a battery replacement or a service. The radio locks itself and displays a code prompt until the correct 4-digit code is entered.
How do I find my Citroën radio serial number?
Depending on the radio type, the serial is either printed on a label on the back of the unit (requires removal with release keys or a pry tool) or displayed on screen. The guide above explains each method step by step.
What Citroën models does this cover?
We cover all Citroën models including C1, C2, C3, C3 Picasso, C4, C4 Picasso, C5, C6, C8, Berlingo, Dispatch, Relay and Nemo, for radios manufactured up to approximately 2018.
What happens if I enter the wrong code too many times?
After a number of incorrect attempts the radio will lock and display a waiting period. Do not keep trying, wait for the lockout to clear before entering your correct code.
