Im guessing someone has did this same thing. I have no excuse but, not paying attention to what I was doing. I connected my Pioneer AVH-P1400DVD in dash player with reverse polarity, It sparked a bit and now it does not work. Does this mean its trash or can I salvage it ? Actually what had happened I was changing coach batteries in my motorhome from a single 12v deep cycle to, two 6v golf cart batteries. The radio was hooked to a hot wire so it would play with out the key on. The battery cables were not identified well (red and black) and they were installed in reverse. When the cable sparked I realized my mistake. Now I need to have it repaired or buy a new one. Does anyone know what I might have blown out, maybe a fuse. I appreciate any assistance to this problem.
