VOLVO do not make radios .They only affix their badge onto radios made by the large manufacturers (ALPINE , DELCO etc).
Supplying the VIN Number is only required when asking at your Main Volvo Dealer (who need it to look up the code on the original database)
In order for us to attempt to calculate your code , please supply your radio MAKE+MODEL plus ALL the NUMBERS+LETTERS on ANY LABELS , BARCODES or STAMPED IN THE METAL CASING
