drive a 1994 Volvo 850 Station Wagon, just to let you know what's happened, my friend Took off the face plate of the stock stereo and tried to pull out the radio but failed and set the viper alarm system off in the process. the stereo was finally put back in but there's just 1 problem.... It needs a code to reset the stereo so the stereo can fully function again. does any one know this code I'm looking for?
