ok heres the deal... im an idiot! I was doing my stereo install.... I accidentally connected the blue amp remote wire to the blue power antenna wire... so at first my new head unit turned on but now it doesnt. Then i tried to reconnect the stock head unit... that didnt work either!! So im checking the fuses and I pull out the radio fuse in the interior fuse box by the dead pedal. It's fine, but i see a disconnected red wire right next to it... can this have anything to do with it? The only other thing that I can think of is that something went wrong with the stock harnass... any suggestions?

 

You might want to check the fuse box under the hood there is a 7.5 fuse that controls the radio it my be blown

 

thanks man.... it was the backup radio fuse that was blown... holy crap this head unit is hotttttttt... sony m800... DSO is awesome
