How do I clear all of 

my user data?

Hold your finger on the lower‑right corner of the 

nüvi screen while it is turning on. Keep your finger 

pressed until the message appears. Touch 

 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 

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 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.
