Not citable, but I have memories of a Garmin GPS-18 going useless and power 
cycling or anything else I could think of didn't fix it.  It did recover after 
sitting around for a month or 3.  I assume it has a supercap rather than a 
battery.

I think I was sending it stuff on the serial/usb port rather than it was 
attacked by nasty RF signals.
