Every Citroën C5 from 2000 to 2017: which radio was fitted, where its serial number hides, and what we can do with it.
Your code comes from the serial number of the radio, not from the car — so the first job is getting that number off the unit. The table below is your C5, generation by generation.
Already have the serial? Type it in and we will tell you straight away whether we can answer it.
| Generation | Radios fitted | Serial | Where to read it | What we do |
|---|---|---|---|---|
| X4/X7 2000–2009 |
RD4, RT3 | PH… | label on the casing — the serial starts with PH (Philips-built unit) or C7 (Clarion) | Free — a share unlocks it |
| X7 2010–2017 |
RT6, SMEG | VIN (17 characters) | the screen carries no serial of its own: the code follows from the car VIN, and we ask which screen is fitted | Free — a share unlocks it |
Radio names are what is written on the fascia, not the name of the company that built the unit — a “6000 CD” or an “RCD 300” is what you see in the car. Unit fitment varies by market and trim, so treat the list as the usual case and let the serial decide: it is the serial that determines the code, not the model.
From 2000 to 2017 the C5 came in 2 generations, and the factory radio — and with it the serial you need — changed along the way. Find your year below.
