GMC Lucerne Automobile User Manual


 
Three types of traffic information for
major roadways are displayed on
the navigation system:
Unscheduled traffic incident data,
such as accidents and disabled
vehicles
Scheduled traffic incident data,
such as road construction and
road closures
Traffic flow information (rate of
speed data)
Traffic information is delivered to the
vehicle by the XM™ Radio satellites.
XM NavTraffic makes it possible for
the navigation system to provide
continuously updated traffic
information personalized for a
driver’s needs.
XM NavTraffic currently broadcasts
the traffic information for many
markets nationally, and the service
may be available in more cities
in the future. Visit xmnavtraffic.com
for more details on local coverage.
A service fee is required in order
to receive the XM NavTraffic service.

when it is active.
Selecting Alert for Approaching
Traffic Events enables the
system to show a pop-up screen
