radio NISSAN SENTRA 2005 B15 / 5.G Owners Manual

ABOUT THE NAVIGATION SYSTEM
This navigation system combines the data ob-
tained from the vehicle (by gyro sensor) and from
GPS (Global Positioning System) satellites to
calculate the current location of the vehicle. This
position is then displayed on the screen, allow-
ing route guidance to a destination.GPS is a system developed and operated by the
U.S. Government, covering the entire planet.
This navigation system receives three or more
different radio signals from NAVSTAR (GPS
satellites) , orbiting the earth 13,049 miles
(21,000 km) above ground. The data from differ-
ent sets of signals are trigonometrically calcu-
lated to obtain the position of the vehicle.
INFO:
The tracking center in the U.S. controls signals
transmitted from GPS satellites. This control
sometimes results in reduced accuracy or no
signal received at all, in accordance with govern-
ment requirements. Consequently, areas such as
military bases may not accurately appear on the
navigation screen.
ACCURACY OF POSITIONING
The color of the GPS Indicatoron the upper
left corner of the screen indicates positioning as
follows:
cGreen: positioning is possible and accurate
cYellow: positioning is possible but accuracy is
minimal
cGray: positioning is not possible
INFO:
For approximately 3 or 4 minutes after system
startup, the GPS indicator
remains gray,
even if accurate positioning is possible.

By using the Avoid Area feature, you can identify
areas or freeways that you would like the
NISSAN Navigation System to avoid when plot-
ting routes. For example, if you know of a freeway
or area that is always congested with traffic, you
can program the NISSAN Navigation System to
plot routes that go around that particular freeway
or area.
For more information on the Avoid Area feature,
please refer to section 8.If you miss a turn while using the Route Guid-
ance feature, the NISSAN Navigation System
will automatically recalculate a new route to your
destination.
For more information on the Automatic Reroute
feature, please refer to section 9.If you hear about a traffic accident on the radio
that is 4 miles (6 km) ahead of you and traffic is
backing up fast, you can use the Detour function
to calculate an alternative route that will help you
avoid the gridlock caused by the traffic accident.
The NISSAN Navigation System has the ability
to find an alternative route using secondary
roads that will return you to primary roads after a
specified number of miles.
For more information on the Detour feature,
please refer to section 9.
