Which radio is in your Peugeot RD3 and RD4?

Peugeot fitted different radios over the years. Find your RD3 and RD4’s years below, but go by the serial: radios are often swapped, and the free check reads it for you.

What is printed on the label

People look these up because they are the only numbers on the radio that mean anything. A part number identifies the unit and is the same on every one ever built; the serial is yours alone and is the one we need. They are easy to mix up, so here is what to expect on a Peugeot RD3 and RD4.

Printed on the unitWhat it is
PHAP123 1234567A Philips PSA serial — one we can look up.
22RC465/65The Philips chassis number for those units.
14 800 360 80The PSA part number for the same unit.
RD3-01, RD4-N1Model names on the later units. Not serials, and not ones we can do.

A part number on its own cannot produce a code — every radio of that model shares it. If the number you have is one of the part numbers above, keep looking for the serial: it is the longer one, and usually on a separate line or a barcode label.

How to find your Peugeot RD3 and RD4 radio serial number

The serial isn’t shown on the screen: it is printed on a label on the radio itself. The serial tells us exactly which code your radio needs.

Where it is

On the label

  1. It is not shown on screen, so take the radio out with radio removal keys.
  2. Copy the serial from the label: 14 letters and numbers starting PHAP.
  3. Radio says RD3? That is a different radio, so type in its own serial instead.

Take a photo of the label rather than copying it by hand: it’s easy to mix up 0 and O, or 1 and I.

RADIOPush both keys in until they click, then pull the radio forward

Most radios slide out with a pair of radio removal keys (a few pounds from any car parts shop). Push them into the slots on the front until they click, then ease the radio forward. Some have screws to undo first.

Tips for your Peugeot RD3 and RD4

  • Look at the label before assuming. A fourteen-character serial starting PHAP is one we hold; an RD3 or RD4 model name is not.
  • On the later units the code sits with the car rather than the radio, which is why a dealer is the route for those.
  • A Boxer or a Bipper is a different story — those carry Fiat radios and we do them instantly.

How to enter your Peugeot RD3 and RD4 radio code

Once you have your code, key it in like this. Your order page shows the same steps next to your code.

Peugeot / Citroën Philips 22RC465

  1. The steps vary from radio to radio (they are not the same as the RD3).

If your Peugeot RD3 and RD4 radio says LOCKED, WAIT or SAFE

Each wrong code makes the radio wait longer before the next try, and some radios lock for good after too many. Don’t guess: get the right code first, then follow the steps for your radio.

Why we use your radio’s serial, not your number plate

A radio code belongs to the radio, not the car. A dealer usually looks it up from the Peugeot RD3 and RD4’s number plate or VIN (the 17-character number in your logbook), which only works if the car still has the radio it left the factory with. Radios are often swapped under warranty, upgraded, or changed by a previous owner.

The serial number is printed on the radio itself, so the code we give you matches the radio in front of you. It is also how we can check it for free before you pay. Main dealers often charge £30–£130, and you usually have to book the car in.

Peugeot RD3 and RD4 radio code questions

Can you do an RD4?

Not at the moment, and we will not pretend otherwise. If the label gives a fourteen-character PHAP serial instead, that one we can.

What about my Boxer van?

The Boxer shares the Fiat Ducato’s radio, and those we do instantly — see our Peugeot page.

How much is a Peugeot RD3 and RD4 radio code?

£9.99 per code. The free check comes first, so you only pay once we know we can do it, and you get your money back if the code doesn’t work.

How long does it take?

Most Peugeot RD3 and RD4 codes appear on screen the moment you’ve paid, and we email you a copy. If yours has to be looked up by our team, we email it within 2 hours and tell you before you pay.

What if the code doesn’t work?

Check the serial first: 0 and O, or 1 and I, are easy to mix up. Still stuck? Tell us from your order page and we’ll put it right or refund you in full.
