2004 corolla with avic-d1 1 sub amp hooked to sub output, parking brake gorunded, open spot next to ground grounded, no dvd player, no extras at all except for amp and the attempt to make unit nav work while driving during driving.

funny so i have no option but to accept that my unit is bad ok thats not funny if you have any advice it would be useful

but me and my friend checked that at the ground and at the connection to the radio harness and both checked good what is the possibility that the input for the bypass went bad

sorry for the last post little misworded so what would would happen if the input for the bypass went bad

what would happen if the input form the input for the bypass next to the ground went bad
