The battery icon 

 in the 

upper right corner of the Menu 
page indicates the status of the 
internal battery. 

Periodically, you might notice 
that the battery gauge is not 
completely accurate. To increase 
the accuracy of the battery gauge, 
fully discharge the battery and 
then fully charge it without 
interrupting the charging. For 
best results, do not unplug the 
nüvi until it is totally charged. 

Your unit contains an internal, non-removable, lithium-ion 
battery. Contact your local waste disposal department for 
information on properly disposing of the unit. 

•  Your nüvi’s battery should last 4 to 8 hours depending on usage. 

The battery gauge indicates the status of the battery.

•  To extend the battery life, close the antenna when you do not 

need to receive GPS signals. 

•  To maximize the life of the lithium-ion battery, do not leave your 

nüvi direct sunlight and avoid prolonged exposure to excessive 
heat. 

•  Do not leave your nüvi exposed in an unattended vehicle on a 

hot day. To prevent damage, remove it from the vehicle; or store 
it out of direct sunlight, such as in the glove box.
