Resetting the NAV 350 
You may have to perform a reset if the device freezes (i.e., 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. 
To perform a soft reset:
•  Hold the device securely, and then press the soft reset 
button (1) on the bottom of the device.
