Hello all. Hoping you can help. When I bought my Jeep there was an aftermarket radio in here that suddenly stopped working. I had another head unit from my compass and ordered the proper wire harness from Crutchfield. I have connected all the wires properly, wrapped the ground around a screw in the dash and.... Nothing. I checked the fuses under the dash and they are fine. I dont know if I'm missing a fuse but I didnt see one fall out.. Any ideas of what could be wrong? It's really like its getting no power through the factory wires/harness.
