XM NavTraffic™ information is a subscription
service offered by XMTsatellite radio.
This service provides real time information re-
garding traffic flow, accidents, road construction
and other incidents, where available.
XM NavTraffic™ combines quality tested infor-
mation from commercial and public traffic data
providers including government departments of
transportation, police, emergency services, road
sensors, cameras, and aircraft reports. The traf-
fic information is broadcast to the vehicle by the
XMTradio satellites. Current traffic information
on the route the driver selected is shown on the
navigation screen so traffic conditions between
you and the destination are known. Three types
of real-time traffic information for major road-
ways are shown on the navigation system:
cUnscheduled traffic data for example, acci-
dents and disabled vehicles.
cScheduled traffic data, for example road con-
struction and road closures.
cTraffic flow information (rate of speed data) .NOTE:
Flow information is provided for only
roads equipped with traffic sensors. Flow
data may not be available on portions of a
road that is under construction.
XM NavTraffic™ information is available in limited
markets. To subscribe or to check if this service
is available in your area call 1-800-XM-RADIO
(1-800-967-2346) or see
www.xmradio.com/xmnavtraffic/

DISPLAY OF CURRENT VEHICLE
LOCATION
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 throughout route guid-
ance to a destination.
WHAT IS GPS (Global Positioning
System)?
GPS is a position detecting system that uses
satellites deployed by the U.S. government. This
navigation system receives radio signals from
three or more different satellites that orbit
13,049 miles (21,000 km) above the earth in
space, and detects the position of the vehicle by
utilizing the principle of triangulation.
Positioning adjustment
When the system judges that the vehicle posi-
tion information is not accurate based on vehicle
speed and gyro sensor data calculations, the
system will automatically adjust the position of
the vehicle icon using GPS signals.
Receiving signals from GPS satellites
The reception of GPS signals can be weak, de-
pending on the environment. Vehicles in the fol-
lowing areas/environments may not receive GPS
signals.

Symptom Possible cause Possible solution
Names of roads and locations differ between Plan
view and Birdview™This is because the quantity of the displayed information is
reduced so that the screen does not become too crowded.
There is also a chance that names of the roads or locations
may be displayed multiple times, and the names appearing
on the screen may be different because of a processing
procedure.This is not a malfunction.
The vehicle icon is not displayed in the correct
position.The vehicle was transported after the ignition switch was
pushed off, for example, by a ferry or car transporter.Drive the vehicle for a while on a road where GPS signals can
be received.
The position and direction of the vehicle icon may be incor-
rect depending on the driving environments and the levels of
positioning accuracy of the navigation system.This is not a malfunction. Drive the vehicle for a while to auto-
matically correct the position and direction of the vehicle icon.
“CURRENT VEHICLE LOCATION” (page 10-4)
When the vehicle is traveling on a new road, the
vehicle icon is located on another road nearby.Because the new road is not stored in the map data, the sys-
tem automatically places the vehicle icon on the nearest road
available.Updated road information will be included in the next version of
the map DVD-ROM.
The screen does not switch to the night screen
even after turning on the headlights.The daytime screen was set the last time the headlights were
turned on.Set the screen to the night screen mode using the Day/Night
button when you turn on the headlights.
“DISPLAY SETTINGS” (page 8-3)
The map does not scroll even when the vehicle is
moving.The current location map screen is not displayed. Press the MAP button.
The vehicle icon is not displayed. The current location map screen is not displayed. Press the MAP button.
The location of the vehicle icon is misaligned from
the actual position.When using tire chains or replacing the tires, speed calcula-
tions based on the speed sensor may be incorrect.Drive the vehicle for a while (at approximately 19 MPH [30 km/h]
for about 30 minutes) to automatically correct the vehicle icon
position. If this does not correct the vehicle icon position, con-
tact a NISSAN dealer.
The map data has a mistake or is incomplete (the vehicle
icon position is always misaligned in the same area) .Updated road information will be included in the next version of
the map DVD-ROM.
