One other thought - on my 1999 V70 I was able to pop out the radio and the code was written on top of the radio.
You can locate the radio code, for your 1991 Volvo, by consulting your owners manual. The owners manual should have all of the vehicle codes.
You need to enter your radio code, it should have been supplied with the vehicle and or written in the front of the owners manual.
Check Owner's Manual. If you do not have one.Check Related links below.
There should be a acura business card in the owners manual that has a reset code
if the code is not located with your owners manual, go to a Lexus dealership to get a code. they may charge you for it.
I had the same problem with mine, I found a web sit with all the codes, all I did was google "codes for daewoo radio" and I found it.

There is no activation code from Volvo, but from individual radio manufacturers. There were many different brands of radio installed in Volvo cars that year, and not only does each brand differ, but each radio has a unique code. What you should do first is look in the owners manual, because it should have been written down. If not, then you need to go to some place that sells that brand of radio, and have the code in it changed. They can't tell you the old code, but they can tell you the new one. It is supposed to be free, as long as you can show ownership.
every radio has its own code it should be in your radio manual
It is part of the security on the car, if someone pulled the radio they could never get it to work. When the car loses power, it resets. The code is in your owner's manual for your car.
try 3523, it worked on my radio.
need to get the security code from a licensed Volvo repair. code is by VIN.
