How to use the Alfa Romeo calculator
- Remove the radio and find the Blaupunkt label – the serial starts with BP.
- Type the last 3 of the 4 digits after BP, then the last 7 digits of the serial (10 digits in total).
- Enter the code with the preset buttons as described in how to enter a radio code.
If your radio shows a different maker, check the Fiat page – Alfa Romeo and Fiat often used the same radios.
