XMTNavTraffic™ 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.
XMTNavTraffic™ combines information from
commercial and public traffic data providers in-
cluding government departments of
transportation, police, emergency services, road
sensors, cameras, and aircraft reports. The traf-
fic information is broadcast to the vehicle by the
XMTsatellites. Available 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) .
mWARNING
XMTNavTraffic™ information is not a
substitute for attentive driving. Traffic
conditions change constantly and
emergency situations can arise without
warning. Relying only on XMTNavTraf-
fic™ information may lead to a collision
and could result in serious personal
injury.
NOTE:
Flow information is provided for only
roads equipped with traffic sensors and is
not available in all markets covered by the
service. Flow data may not be available on
portions of a road that is under
construction.
XMTNavTraffic™ information is available in lim-
ited markets. To subscribe or to check if this ser-
vice is available in your area:

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.
