Sooo I installed my fuel pump which required me to move my amp a little and I guess this caused the antenna/remote wire to come loose.I turn my car on realize my amp is off and hook the wire back up, I accidentally touch the ground and BAMM! nothing works now. Navigation,radio and AC/radio/time etc display do not turn on.. fuse is still good. Has anyone had this problem?..I'm really hoping I don't need to replace it all.

 

I think you need to go through everything very thoroughly. Most likely it is a fuse blown somewhere. I think the chances are on your side that it is a fuse. Did you check your major fuses under the hood? Those are the big square ones in the box under the hood. Hopefully you blew one of those. Considering that your amp shouldn't be wired through the other devices you had to have blown something controls the juice to everything. So you should be looking for a fuse toward the "front" of the system.

 

Did you check the fuses under the hood as well?

 

Checked them all and they're good :/

 

First thing to do is check to see if you have +12V on the hot side of one of the factory devices. Do you have an ETM? If not you probably should get one.

 

Check the Accessory fuse, #32, inside the car near the driver's left foot. This is the last power stop before hitting the devices you mentioned. Good luck and keep us posted!
