Solution/Answer
Take your PND out of parking garages and away from tall buildings
and trees. Remain stationary for several minutes.
Hold your finger on the lower-right corner of the PND's screen while
it is turning on. Keep your finger pressed until the message appears.
Touch Yes to clear all user data.
If the PND screen stops functioning, turn the PND off and on again.
If this does not help, slide the
seconds. Turn the PND back on. The PND should operate normally.
Turn the PND off and then back on. Slide the
(lock). Hold your finger on the screen for about 30 seconds until the
calibration screen appears. Follow the on-screen instructions.
Allow the unit to fully discharge, and then fully charge it (without
interrupting the charge cycle).
When your PND is in USB mass storage mode, a picture of a PND
connected to a computer is shown. Also, you should see two new
removable disk drives listed in
1. Unplug the USB cable from your computer.
2. Turn the PND off.
3. Plug the USB cable into your computer and your PND. The PND
automatically turns on and goes into USB mass storage mode.
If you have several network drives mapped on your computer,
Windows may have trouble assigning drive letters to your PND
drives. See your operating system's Help file to learn how to map/
assign drive letters.
