bought the metra kit for my g6 and the screen would like, scroll and look like it was going to burn out and was very dim....so they sent me another one and its doing the same thing, only now...its shorting out and shutting off the kit and my radio??? if i take out the radio fuse on the side of the console and plug it back it it will work again....any ideas? if it was a short you would think it would pop the fuse?
