OVERVIEW | XM Satellite XM NavTraffic System

1st Nation-Wide Data Traffic Service
XM NavTraffic, powered by NAVTEQ Traffic, is the 1st nationwide satellite-based data traffic information service that enables an overlay of current traffic conditions. The best available traffic information, aggregated by NAVTEQ Traffic from multiple sources, is provided via continuous satellite broadcast to an on-board vehicle navigation system.

Traffic Between You & Your Destination
Previously, GPS navigation systems calculated routes to a destination, with no knowledge of true traffic conditions along the planned route. XM NavTraffic provides detailed NAVTEQ Traffic information overlaid on the navigation road map, allowing the navigation system to show the traffic conditions between you and your destination.

XM NavTraffic Information
Roadways for which traffic flow information is available are shown by color-coding to indicate directional traffic flow speed. Accidents, road construction or other incidents affecting traffic are graphically represented on the navigation map with an icon at the location of the incident. Information relating to a traffic incident is also available including the precise location, lanes affected, and the predicted duration.

Benefits of XM NavTraffic:

• Traffic flow data, indicating the average traffic speed along major highways (where available)
• "Personalized Traffic Information" for current location and destination
• Visual presentation for clear "at-a-glance" communication
• Advanced notification of congestion along traveled route
• Aids a driver to re-route around upcoming congestion

Traffic Aggregator: NAVTEQ Traffic
NAVTEQ Traffic delivers seamless traffic flow and incident information for the XM NavTraffic service. NAVTEQ Traffic provides data that has been aggregated from multiple sources across the country, including the leading commercial traffic data providers, government departments of transportation, police & emergency services, road sensors, cameras and real-time aircraft reports. NAVTEQ Traffic performs extensive data quality processing to provide the most complete and accurate nationwide traffic information feed. The traffic data is continuously broadcast via XM's network of satellites and ground-based repeaters, ensuring that the latest information is available to the driver.

Designed as the Industry Standard
The XM NavTraffic service has been designed as an industry standard for flexible integration into a variety of navigation platforms regardless of map database support. The new 2005 Acura RL will have the XM NavTraffic service as standard equipment. Other new vehicle announcements as well as aftermarket products supporting the XM NavTraffic service are expected in the near future.

20 Market Launch and Growing
XM NavTraffic, supported by NAVTEQ Traffic, will broadcast nationally the traffic information for 20 markets with the launch of the new 2005 Acura RL.
