As the title suggest I am looking for help into why my aftermarket radio blew the illumination portion of my dash. I checked the fuses and they were fine. The radio that I installed was a Sony explode model CDX-S2210, using an aftermarket wiring harness from a reputable dealer. During the installation I checked all wires more then once and am completely sure they were wired correctly. I brought the vehicle into my local dealership to ask them to see what was wrong. They were telling me that a ground wire within the dash had now become charged with positive power and it caused a short to occur which in turn blew a selonoid and the gauges were the clock is in the center console. In order to fix the problem they had to replace my entire gauge cluster. They blammed the problem on my radio and charged me $500 for repairs. I don't see how this is possible and am thinking there was a defect some place within the dash. I also think the dealership itself used the radio excuse so they wouldn't have to do the repairs under warranty. Has anyone else experienced any problems with the electrical within the dash?
