With my 910 it was working fine until a few days ago it just stuck at the splash screen. Once I restarted it stays at the splash screen for a couple seconds then it comes up like saying its reflashing the gps firmware and once it installs it turns it else off. I cannot get it out of this cycle no matter if I do a hard reset or not. The unit can be seen in windows when plugged in via usb but I do not have a copy or backup to restore to. Any suggestions would be greatly appreciated.
