CHICAGO, IL., Dec. 14, 2004 -- NAVTEQ (NYSE: NVT), a leading global provider of digital map data for vehicle navigation and location-based solutions, has been selected by SIRIUS Satellite Radio (Nasdaq: SIRI), a premium satellite radio provider known for delivering compelling commercial-free music and sports programming to cars and homes across the country, as the traffic data provider for the SIRIUS traffic service.

SIRIUS' new service will provide consumers with regularly updated traffic information, such as accidents, scheduled road closings, traffic flow data or other traffic-related incidents to help them select the best available route. Traffic information will be integrated into new in-car navigation systems combining route guidance and mapping with traffic. Initially, SIRIUS' service will cover 30 markets and is expected to expand to over 50 markets.

"This new data service will complement SIRIUS' First Traffic audio service by providing a visual representation of current traffic conditions. Over time, additional features will be added to help determine estimated drive times on a given route, based on historical traffic patterns," said Jim Meyer, President of Operation and Sales for SIRIUS. "Combined with an in-car navigational system, consumers will be able to accurately determine the most direct routes through the mapping function, while being continuously informed about potential delays or incidents that could disrupt their travel plans."

"Delivering traffic information via satellite radio brings a new dimension to the navigation experience," said John MacLeod, Executive Vice President - Global Marketing and Strategy for NAVTEQ. "Together with SIRIUS, we will offer a traffic service that assists drivers in making informed, time-saving routing decisions,"

SIRIUS automotive and retail partners have shown a high level of interest in the new service, and plan to offer it as a product upgrade for their upcoming navigational systems.
