After running to the store earlier today, my F700BT seems to have become unfunctional. My unit will turn on when I turn on the car, show the splash screen for about 20 seconds then shut off. The lights for the buttons shut off as well and pressing the buttons does nothing. My unit is un-hacked, the only changes I made were to use custom images for the splash screen and menu icons, and replace the navigation sounds with blank sound files. After some searching on the forums, I found several other threads with similar problems so I've been trying to work through the various fixes posted.
