New Vehicles With XM Navtraffic Debut At New York Auto Show

XM NavTraffic Delivers Real-Time Traffic Information for Drivers in 31 Markets Across the U.S.

Washington D.C., April 13, 2006 -- XM Satellite Radio, the nation’s leading satellite radio company with more than 6.5 million subscribers, today announced that XM NavTraffic, the first nationwide satellite traffic information service for GPS navigation systems, will be available in the Acura RDX, the Infiniti G35 sedan, and the Lexus LS sedans beginning with the 2007 model year vehicles. XM NavTraffic is already a factory-installed feature on all Acura RL vehicles and every Cadillac CTS model equipped with on-board navigation.

The latest vehicles with XM NavTraffic are on display at the 2006 New York International Automobile Show at the Jacob K. Javitz Convention Center in Manhattan.

In-car navigation systems are among the auto industry’s most in-demand new vehicle features, but most navigation systems are blind to traffic jams around the next corner. XM NavTraffic empowers navigation systems by delivering real-time traffic information for drivers in 31 markets from New York to Los Angeles. The XM NavTraffic technology was recently selected as a 2005 “Best Consumer Vehicle Application” by the leading telematics industry organization Telematics Update.

Using XM’s coast-to-coast satellite signal, the XM NavTraffic service continuously delivers traffic data directly to GPS navigation systems. XM NavTraffic data enables an overlay of color-coded traffic flow information on the navigation map, indicating how fast the traffic is currently moving on the driver’s personal route. Accidents and road construction are identified on the map by icons.

XM NavTraffic can show at-a-glance traffic conditions between driver and destination, allowing the driver to avoid a jam before getting caught in traffic. The traffic data is aggregated for XM by NAVTEQ Traffic from multiple data sources, including police and emergency services, commercial traffic data providers, road sensors, traffic cameras, eyewitness reports, and real-time aircraft surveillance reports.

“XM’s strategic automotive partners are rapidly embracing XM NavTraffic,” said Roderick MacKenzie, XM’s vice president of advanced applications and services. “XM expects to expand the availability of XM NavTraffic in more new vehicles in the months ahead.”

In addition to vehicles with in-dash XM NavTraffic systems, XM NavTraffic is also available on a growing number of aftermarket navigation systems that are designed to fit virtually any vehicle on the road. Garmin International recently introduced the StreetPilot 2730, the first-ever portable navigation device to feature XM NavTraffic as well as XM Weather and XM Satellite Radio. Partners such as Pioneer Electronics and Alpine also offer XM NavTraffic-compatible systems.

Offered as a premium data service for $3.99 per month when packaged with XM Satellite Radio’s subscription of $12.95 a month, XM NavTraffic is currently available for the following 31 markets: Atlanta, Baltimore, Boston, Chicago, Cincinnati, Cleveland, Dallas/Ft. Worth, Denver-Boulder, Detroit, Houston, Los Angeles, Miami-Ft. Lauderdale, Milwaukee-Racine, Minneapolis-St. Paul, New York, Orlando, Philadelphia, Phoenix, Pittsburgh, Portland, Providence-Warwick-Pawtucket, Sacramento, San Antonio, San Diego, San Francisco/Oakland, San Jose, Seattle, St. Louis, Tampa, Washington DC and Wilmington, DE.
