Battery Information
Your unit contains an internal (non-
removable) lithium-ion battery. The
battery should last up to 8 hours,
depending on usage.
The
battery icon in the corner
of the Menu page indicates the status of
the battery. If the icon is not present, the
nüvi is connected to external power.
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.
Contact your local waste disposal
department for information on properly
disposing of the unit.
Maximizing the Battery Life
Turn off GPS Mode when you do not
need to receive GPS signals, or use
normal mode when you do not need
to use WAAS or EGNOS.
Turn the backlight brightness down
(on the Menu page, touch ).
