I bought JIMMY almost 6 years ago when I was like 12. I dont think my stereo is stalk after lkooking in my manual and not seeing its style in there. While installing my new steering column last year it seems I unplugged my stereo. I plugged it back in every fuse till I found one that worked. (i forgot where I unplugged it from) Ever since then my stereo doesnt remember the presets because I dont have it in a constant power source fuse. Finally last week I had time to re-connect the fuse with the right wire so I plugged the stereos wire into the radio fuse but still It isnt getting constant power it seems. What gives? 1985 k-5 gmc jimmy 4x4 sierra classic. 1970 cuda 440 6 pack executive edition steering column shift.
