PPENDIX

My battery gauge does not 

seem accurate.

Allow the nüvi to fully discharge and then fully 

charge it (without interrupting the charge cycle).

The touch screen is not 

responding to my taps 

properly.

Calibrate the screen. On the Menu page, touch 

 > 

. Touch the 

 button 

and follow the on-screen instructions. 

Your nüvi contains an internal (non-removable) lithium-ion battery. Contact your local 

waste disposal department for information on properly disposing of the nüvi. 

•  Your nüvi’s battery should last 4 to 8 hours, depending on usage. 
•  To extend the battery life, reduce the time the backlight stays on. On the Menu 

page, select 

> 

 > 

 to change the setting.

•  Close the antenna when you do not need to receive GPS signals. 
•  To increase the accuracy of the battery gauge, fully discharge the battery and 

then fully charge it. You should not need to do this very often.

•  Do not leave your nüvi in direct sunlight, and avoid prolonged exposure to 

excessive heat.
