1998 Volvo S90 Q&A
1998 Volvo S90 Question: I have an S90 with the original cd/radio/tape in it. The display reads "OFF"?
Do you have your pass code? - Hyedegha
You'll need to leave the radio on for an hour or so, until the display reads "CODE". Then enter the 4 digit code. If you don't have it, you can get it from your Volvo Dealer. - Bret Bodas
