Haven't used my VIA 53 in about 8 months. Need it now. Connected to computer via USB cable for greater than 3 hours. Turned it on and it just cycles through trying to boot (light blue screen with countries and a white progress bar at the bottom), screen goes blank and tries to boot again. Boot fails and screen now shows window with computer & GPS unit NOT attached to computer (Windows 10 64-bit). Tried a soft reset and then a hard reset (get the screen with white text on a black background), press 3 times quickly, connect to computer and start process all over again. Never will boot up.
