If the device still does not power on, or if the screen has become frozen and will not power off, a soft reset can help by forcing the device to reboot.
To Perform a Soft Reset:
Connect the device to a power source with its Vehicle Power Cable.
An A/C adapter may also be used, but if the problem persists, the Vehicle Power Adapter will need to be used.
Press and hold the power button or hold the power switch in the "on" position, and slowly count to 30.
The device should now turn on. Leave the device connected to power to give the battery time to charge.
If the device "freezes" on a single screen and will not respond to your touch, the device may have run into a software "bug", "glitch", or other similar types of problems.
Since all electronic devices do a large number of tasks and calculations every second, it is always possible for the device to get stuck at one point or another while in use.
This problem may be solved with a software update. See the applicable FAQ below for instructions:
