Which radio is in your Vauxhall CDR500?
Vauxhall fitted different radios over the years. Find your CDR500’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 CDR500.
| Printed on the unit | What it is |
|---|---|
| GM0205Y9019162 | The serial. Fourteen characters, usually starting GM. |
| 7 649 200 324 | The Blaupunkt part number, when Blaupunkt built it. Nine digits in threes. |
| 24 434 773 | The GM part number for the same unit. |
| GM0203, GM0205 | The first six characters of the serial, which name the unit rather than your copy of 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 CDR500 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
- The serial is not shown on screen.
- Take the radio out with radio removal keys (some have extra screws to undo first).
- Copy the serial from the label: 14 letters and numbers starting GM.
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 CDR500
- The CDR500 will not show its serial. Take it out with radio removal keys and read the label on the top or side.
- A serial starting GM goes to our code lists. One starting BP is a Blaupunkt-built unit and is worked out instead — the free check sorts out which you have.
- You get ten tries on these and then the radio locks for good. Never guess.

How to enter your Vauxhall CDR500 radio code
Once you have your code, key it in like this. Your order page shows the same steps next to your code.
- 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.
- 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.
If your Vauxhall CDR500 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 |
|---|---|
| Vauxhall CDR500 / CDR2005 | You only get 10 tries before the radio locks for good, so please don’t guess. |
| 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. |

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 CDR500’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 CDR500 radio code questions
Where is the CDR500 serial?
On the label on the radio, so the unit comes out on removal keys. Fourteen letters and numbers, usually starting GM.
How many tries do I get?
Ten. After that the unit locks permanently and needs replacing, which is exactly why we show you the first digit free before you pay.
How much is a Vauxhall CDR500 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 CDR500 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.
