What is the code for a radio in a 1992 volvo 940 GL

Each and every stereo in each and every car has a different code usually a four digit one.Try looking in the owners log book case for the key code it may be written down on a small piece of paper or it could be hidden away in the glove box or in the little sleeves on the sun visors which is common.If you dont manage to locate the code im afraid to say it will have to be recoded but depending on the age of the stereo and the price of recoding sometimes its cheaper just to renew your stereo, Hop this helps!!!!!!
