CUSTOMIZING THE ZŪMO
Changing the System
Settings
Touch > System.
GPS Mode—enable and disable GPS
and WAAS/EGNOS. Turning on the
WAAS/EGNOS setting might improve
GPS accuracy, but it consumes more
battery power. Go to
www.garmin.com/
aboutGPS/waas.html for information
about WAAS/EGNOS.
Safe Mode—turn Safe Mode on or off.
When your vehicle is moving, Safe
Mode disables all functions that require
significant operator attention and could
become a distraction while driving.
Garmin Lock—turn on Garmin Lock
™
to lock your zūmo. Enter a 4-digit PIN,
and set a security location. For more
information, see page 10.
About—display your zūmo’s software
version number, unit ID number, and
audio version number. You need this
information when you update the system
software (see page 49) or purchase
additional map data (see page 50).
Restore—restore the default system
settings.
