XM NavTraffic Adds Two More Cities

XM Satellite Radio said its traffic service would expand to Orlando and Tampa, Fla. June 15. Right now, XM NavTraffic is in 20 metro areas.
Using XM’s satellite signal, the XM NavTraffic service delivers traffic data to factory-installed and aftermarket GPS navigation units. XM NavTraffic can provide an overlay of color-coded traffic flow information on the map of a navigation system, which indicates how fast the traffic is moving on a driver’s chosen route.
NAVTEQ Traffic aggregates the traffic data from multiple sources, including police and
emergency services, commercial traffic data providers, road sensors, traffic cameras, eyewitness reports, and aircraft surveillance reports.
XM NavTraffic debut in fall 2004 as a standard feature on the 2005 Acura RL and is now available as an option on the 2005 Cadillac CTS.
Pioneer Electronics recently introduced its first aftermarket in-car navigation systems compatible with XM NavTraffic, the Pioneer AVIC-N2 and the AVIC-D1.
XM NavTraffic is a premium data service for an additional $3.99 per month when packaged with the XM Satellite Radio audio subscription.
