The six new XM NavTraffic markets include: Fresno, CA; Jacksonville, FL; Montreal, QB; Salt Lake City, UT; Toronto, ON; and Vancouver, BC. In addition, Portland, OR now has expanded coverage with traffic flow data available allowing drivers to see how fast the traffic is moving.

XM NavTraffic feeds data on incidents, such as accidents and road construction, directly to a vehicle’s GPS navigation system via XM’s satellite pipeline. The driver is alerted to these blockages through the navigation screen, allowing him or her to route around a jam before getting caught in traffic. Where available, XM NavTraffic also provides information that allows users to view an overlay of color-coded traffic flow information, indicating the average speed of travel along the driver’s planned route. The traffic data is aggregated by NAVTEQ Traffic from data sources that include police and emergency services, commercial traffic data providers, road sensors, traffic cameras, eyewitness reports, and real-time aircraft surveillance reports.

NavTraffic is available as a factory-installed feature on new models from Acura (MDX, RDX, RL, TL), Cadillac (CTS), Infiniti (G35 Sedan), Lexus (LS 460 L, LS 460, LS 600h L), and Nissan (Altima), as well as through a number of aftermarket and handheld units from Alpine, Garmin, Kenwood and Pioneer Electronics. Selected as the 2005 “Best Consumer Vehicle Application” by Telematics Update, the leading telematics industry organization, XM NavTraffic is expected to be available in 200,000 vehicles by the end of 2008.

In addition to the six new markets available March 31, XM NavTraffic is currently available in the following 44 metro areas: Atlanta, GA; Austin, TX; Baltimore, MD; Boston, MA; Buffalo – Niagara Falls, NY; Charlotte, NC; Chicago, IL; Cincinnati, OH; Cleveland, OH; Columbus, OH; Dallas – Ft.
