hey guys i have a question about my stereo. about a week ago i got into my truck and my stereo displayed the time @ 1:60. I tried to fix this but realized there was also no sound coming out. I cannot tune at all, turn volume up or down, get any of my presets to work at all. i tried to put another stereo in today (same kind) and the same problem appeared on it. I have a 1992 GMC 1500 4x4 with a western v-plow on it and the stereo is a stock ac delco original. I would appreciate any ideas to try as i hate driving when it is so quiet. thanks in advance ______________ work smarter not harder!!
