Citroën calculators
| Calculator | Use it for |
|---|---|
| Blaupunkt Citroën | most Blaupunkt-made Citroën radios |
| Blaupunkt Citroën (1/0 variant) | radios where the first code digit can only be 0 or 1 |
| Blaupunkt Citroën (older units) | older Citroën cars |
Enter 10 digits for all of them: the last 3 of the 4 digits after BP and the last 7 digits of the serial. Check the serial twice before entering a code – wrong codes block the radio for a while (locked radio help).
