Reference the previous reply from "john sergeant" - that's a good reply. I also had radio problems with the code - I had some body work done on my front right side. When I got the car back, the radio had been zeroed, as the battery had been disconnected. The body shop contacted Volvo and gave us the code (I had bought the car second hand and knew nothing about a radio code!). Since this time, I have changed car batteries, and Volvo radios myself - therefore I've dealt with radio codes. I have acquired 2 radios from salvage yards (pullapart & u-pull-it). The radios were 15 bucks both times. I did find the 4 digit radio code written in black ink on both radios. THIS IS VERY COMMON - Look on your radio for a 4-digit code number, and try entering this,...if that does not work, give the radio serial number to someone at ANY car dealership, (that will help you on this - like JOHN SERGEANT REPLY), and they should be able to get Volvo to yield the number. It should not cost you a cent!
