How to use the Volvo truck calculator
- Take the radio out (or read the label if it is accessible) and find the serial number.
- Type all 16 characters – they start with 89F – without spaces.
- Enter the code on the radio and confirm as shown in your owner’s manual.
A single wrong character gives a different code, so compare the serial twice before entering it. If the radio still refuses the code, send us the serial.
