I am installing an aftermarket gps in my gc, i took the old head unit out, installed the new one. Now nothing works even the stock head unit. I have checked every fuse with no luck. If you look in the manual there is no battery fuse. I am assuming something blew somewhere just cant figure it out.

Anybody have any suggestions??

Thanks

What do you mean when you say nothing works? Does it power on and no sound, or is there no power at all?

What factory sound system did you have in the vehicle?

Thanks for the response; however, i figured it out. It was the #28, 20amp fuse under the hood in the first fuse box. Not sure if this will help anybody out because it does not show a fuse for the radio in the manual.
