Go 400 seems to keep rebooting
the device boots up fine, but when the time comes to switch to the map view, the screen goes blank, then device seems to reboot and keeps doing this.
it will connect to computer fine, can update maps, and the connected to computer screen stays on, whilst the device continues to seem to reboot in the background.
when the menu button appears i get about 5 seconds to navigate the menu before the screen goes blank and then seems to restart.
its like it cant access the map, and keeps trying.
ive restored the device and tried resetting with the power button, but its still the same.
Whats gone wrong?
