Navigation System 99
System Set-up
Auto Daylight
Sets automatic daylight saving time ON
or OFF. If set to ON the navi clock will
automatically “spring ahead” or “fall
behind” by one hour when a daylight
savings 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 Auto
Daylight function is activated even in an
area that does not adopt the Daylight
Savings Time system.
The federal government has mandated
that, starting in 2007, daylight savings
time will change in March & November
instead of the old schedule in April &
October. The new government daylight
savings time schedule is subject to
review and possible cancellation in
2008.
The dates that the navi switches between
standard and daylight savings time are
not triggered by GPS satellite signals.
They are stored in the navi software and
can be selected in the DST schedule
selection screen. Therefore your navi
clock will change based on the daylight
savings time schedule.
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.
