Which radio is in your Vauxhall CAR300?
Vauxhall fitted different radios over the years. Find your CAR300’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 Vauxhall CAR300.
| Printed on the unit | What it is |
|---|---|
| 7 640 852 520 | The Blaupunkt part number. The middle three digits reappear inside your serial. |
| 24 455 376 | The GM part number for the same unit. |
| GM030M | A serial prefix — it names the unit, not your copy of it. |
| A 14-character serial | If the label gives one of these, it is the shape our calculation reads. Type it in and the free check settles it. |
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 Vauxhall CAR300 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.
On the label
- Some radios show it: hold DISP or DISPLAY for a few seconds.
- Otherwise take the radio out and take a photo of the label.
- Copy all 14 letters and numbers, like BP3782R3701682.
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.
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 Vauxhall CAR300
- Take the unit out and read the label rather than going by the year. Plenty of Vauxhalls of these years are Blaupunkt underneath.
- If the label gives a fourteen-character serial, type it in — the free check settles in a second whether we can do it.
- If instead the car is matched to its Car Pass, no serial code exists and a dealer is the honest answer.

How to enter your Vauxhall CAR300 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.
- Buttons 1 to 4 each set one number.
- Hold button 5 (or the tuning knob) to finish.
- Won’t go above 1 for the first number? Use the second code we give you.
- Hold AS and switch the radio on. The screen shows SAFE, then 10 - - - -.
- Buttons 1 to 4 set each number.
- Hold AS until it beeps.
If your Vauxhall CAR300 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.
| Radio | What to do |
|---|---|
| Blaupunkt / Bosch | After a wrong code, most Blaupunkt radios make you wait before the next try, and the wait gets longer each time. Leave the radio switched on until it asks for the code again. |
| Vauxhall CDR500 / CDR2005 | You only get 10 tries before the radio locks for good, so please don’t guess. |

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 Vauxhall CAR300’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.
Vauxhall CAR300 radio code questions
Can you do a CAR300?
If it carries a fourteen-character serial, very likely yes, and instantly. The free check tells you before you pay a penny.
What is the number starting 7 640?
The Blaupunkt part number. It names the model, not your particular radio, so it cannot produce a code on its own.
How much is a Vauxhall CAR300 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 Vauxhall CAR300 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.
