Which radio is in your Nissan Clarion PN-Series?

Nissan fitted different radios over the years. Find your Clarion PN-Series’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 Nissan Clarion PN-Series.

Printed on the unitWhat it is
PN-xxxxxA Clarion model number. It names the unit, not your radio.
The barcode numbersWhat a Clarion code is actually worked out from.
A Nissan part numberPrinted alongside, and shared across the model. Not a serial.

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 Nissan Clarion PN-Series 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. Take the radio out.
  2. Find the barcode label (use the bottom one if there are two).
  3. Type in its last 4 numbers.

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 Nissan Clarion PN-Series

  • Photograph the whole label. On a Clarion the barcode is what matters, not the model number above it.
  • A glovebox label with twelve characters is the immobiliser PIN rather than the radio code — different thing, different page.

How to enter your Nissan Clarion PN-Series radio code

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

DISPLAY~~~~~~~~~~~~~~~~!!!!!!CODE!!!!!!123456BUTTONS 1–6
Press button 1 twice for 2, button 2 four times for 4, button 3 once for 1, button 4 three times for 3, then confirm the way your radio’s handbook shows.

Clarion (barcode)

  1. Buttons 1 to 4 set each number. Clarion codes only use the numbers 1 to 6.

If your Nissan Clarion PN-Series 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 Nissan Clarion PN-Series’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.

Nissan Clarion PN-Series radio code questions

Can you do a Nissan radio?

The Clarion-built ones with a barcode, often yes. Nissan’s Blaupunkt MMR units are not ones anybody has published a method for, and we will say so rather than guess.

What is the twelve-character number in my glovebox?

That is the immobiliser PIN, not a radio code. We do those separately.

How much is a Nissan Clarion PN-Series 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 Nissan Clarion PN-Series 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.
