Problem/Question Solution/Answer
How do I clear all of
my user data?
Hold your nger on the lower‑right corner of the
nüvi screen while it is turning on. Keep your nger
pressed until the message appears. Touch Yes to
clear all user data.
My battery gauge
does not seem
accurate.
Allow the unit to fully discharge, and fully charge it
(without interrupting the charge cycle).
The touchscreen is
not responding to my
touches.
Calibrate the touchscreen as described on page 51.
How do I know my
nüvi is in USB mass
storage mode?
When your nüvi is in USB mass storage mode, a
picture of a nüvi connected to a computer is shown.
Also, you should see two new removable disk drives
listed in My Computer.
My computer never
senses that the nüvi
is connected.
1. Unplug the USB cable from your computer.
2. Turn off the nüvi.
3. Plug the USB cable into a USB port on
your computer and into your nüvi. The nüvi
automatically turns on and goes into USB mass
storage mode.
