Code on radio fix ..?

See owners manual for explanation... Full index is in back of book.

When you lose power to the radio, normally due to a dead battery, this message will appear. There's a unique 4-digit code that needs to be entered using the radio preset buttons. You may find this code in your owners manual, and if not you will have to contact a Volvo dealership. Be careful though, if you enter the incorrect code 3 times it will switch to "OFF". Then you have to reset the radio by leaving it on for an hour or so. Good luck

You might find the code written down in the manuals by the old owner, or yu need to contact volvo for the code based on the vin number
