i was changing the deck in my truck and then all of a sudden shit stopped workn. the deck was getting power(lights on) but wouldnt do anything and the screen was off. the same thing happened when i tried the other deck then nothing. no power no nothing. i checked all the fuses and i even did some sort of reset i was told to do where i disconnected my batter and no luck. could anyone please help me, it would be much appreciated.
