After installing a subwoofer and amp I reconnected the battery and ran into a problem. When I turn my car to on my navi and clock areas are blank and I cannot enter my code. Usually it says code but it's just blank. Anyone know what's going on??

 

Did you try turning the power on the radio? No offense...but sometimes it is the simplest thing, check your radio/nav fuse too.

 

I stemmed to figure it out already. I needed a bigger fuse on the # 32 slot since spliced in the remote wire.

 

Good deal...
