BMW serial number BP, 4 numbers, a letter, then 7 numbers

This unit does not show its serial on screen. Holding DISP, which you may have read about, puts the radio into code entry rather than revealing a serial, and wrong attempts can lock it for longer.

You will needA set of release keys (flat U-shaped pins), a few pounds from Halfords or any motor factor.

1Slide a release key into each of the four corner holes on the face of the radio.
2Push them in until the clips let go, then draw the unit straight out.
3The serial is on the label on the back or side of the casing, or engraved into the metal.

Take it off the radio, not off paperwork. The number in the handbook or on a dealer invoice is often for a different unit than the one actually fitted, and a wrong serial buys you a wrong code.

Frequently asked questions

Is the Business CD a factory-fitted radio? +

Yes. The BMW Business CD is an OEM (original equipment manufacturer) Blaupunkt radio that came standard on many BMW models from the 1990s–2010s. It is not an aftermarket radio.

Do you support BMW iDrive or navigation systems? +

No. Our service covers standalone BMW Business CD Blaupunkt radios only. If your BMW has an integrated iDrive system or modern touchscreen, that's a different system and we cannot help.

find your make on our brands page, or ask us and we will tell you if we can help. It may work for newer systems.

Do I need to remove the radio to find the serial? +

No. The serial is displayed on the locked radio's screen. You do not need to remove it. Just turn on the ignition and look at the display.

Can I get the code from BMW instead? +

Yes, but it's more complicated. BMW dealers can provide codes if you prove ownership with your V5C and photo ID. However, it usually takes several working days and there is usually a charge.

Our £4.99 service is instant, online, 24/7.

Is my data private? +

Yes. We do not store your serial, vehicle details, or personal information beyond what's needed to process your order. We use Stripe for payment. We never see your card details.

We do not sell or share any of your data.
