Navigation System 101
System Setup
Auto Daylight
Sets automatic daylight saving time ON
or OFF. If set to ON, the clock will
automatically “spring ahead” or “fall
back” by one hour when a daylight
saving time change occurs. If you reside
in a state or area where daylight saving
time is not used, then you may want to
turn this feature off.
NOTE:
If you set Auto Daylight to ON, the
daylight saving time function is
activated even in an area that does not
use daylight savings time.
The federal government mandated that
starting in 2007, daylight saving time
begins in March and ends in November
instead of the old schedule from April to
October. The new schedule is subject to
review and possible cancellation in
2008-2009.
The schedules for the time changes are
stored in the software and can be
selected in the DST schedule
selection screen. Therefore, your clock
will change based on the daylight saving
time schedule.
NOTE:
The automatic clock setting feature
relies on a satellite signal. It will not
work correctly in Hawaii and Alaska.
Auto Time Zone
Sets automatic time zone selection by
GPS to ON or OFF. If you are driving
across the country and passing through
time zones, then this feature will
automatically set the time to the time
zone you are traveling through.
However, if you live and work in two
different time zones, you may want to
turn this feature off.
NOTE:
When driving near a time zone
boundary, the displayed time zone may
fluctuate between the two zone times.
