RESETTING Nav100 OR LOADING THE FACTORY
DEFAULT SETTINGS
You may have to perform a reset if the device freezes (i.e.,
the device no longer responds to the buttons on the
screen). A soft reset allows your device to get a fresh
start, similar to rebooting a computer. This will restart
your device and adjust memory allocation. All records and
entries are retained after a soft reset. GPS settings are
also retained.
1 Hold the device securely, and then press the soft reset
button »
Z« on the bottom of the device.
If you still encounter system errors even after soft
resetting the device, load the factory default settings to
correct the error. These default settings have been
selected to optimize your device’s performance.
2 Tap »Factory Reset« on the system info screen.
3 Tap »Yes« on the dialog box.
4 After the factory reset, reconfigure your device’s user
preferences.

navigation mode.
