2008 Chicago Auto Show : Acura and XM Announce Acura RL to Offer XM NavWeather

Ground-Breaking, Real-Time, Weather Tracking Service for GPS Navigation Unveiled in 2009 Acura RL at 2008 Chicago Auto Show

CHICAGO, Feb. 6 -- Acura and XM announced today that the 2009 Acura RL will offer XM NavWeather(TM) featuring Threat Matrix(TM) technology as a part of its AcuraLink(R) service. The new Acura RL was unveiled today at the 2008 Chicago Auto Show and will be on display in the Acura booth. Acura is XM's first automotive partner to debut the XM NavWeather service.

2009 Acura RL drivers will be able to experience real-time, personalized weather tracking service directly through the in-dash navigation system. XM NavWeather utilizes exclusive "Threat Matrix" technology to track and provide drivers immediate alerts on developing weather threats, such as hail, floods, tornado and storm warnings. To help inform RL drivers of weather conditions at a glance, the easily understood icons are integrated into the luxury sedan's large map display.

XM NavWeather transmits detailed nationwide weather information for more than 20 different weather conditions, scaled and customized for the driver's specific route and displayed on the vehicle's navigation screen. XM NavWeather also provides multi-day forecasts based on weather monitoring stations across the U.S.

XM NavWeather was developed with Baron Services and utilizes Baron's exclusive Threat Matrix technology. Baron Services is also XM's weather partner for its award-winning XM WX Satellite Weather, a trusted information source for professional pilots and mariners. XM NavWeather builds upon the success of this professional grade service by providing a "driver friendly" interpretation of the dynamic weather data direct to the vehicle's navigation screen.

"Acura was the first automotive partner to debut our award-winning real- time XM NavTraffic service, which makes it fitting that they are first to offer XM NavWeather," said Steve Cook, executive vice president, Automotive, XM Satellite Radio. "Drivers will soon find the convenience of both services impossible to live without."

"Acura is a leader in developing the latest in customer relevant technologies that advance the driving experience," said Dick Colliver, executive vice president, Acura sales. "The real-time weather system featured on the new 2009 Acura RL further connects the driver to the world around them, allowing them to get where they need to go more quickly, safely and efficiently."

"Drivers don't have time to scrutinize every bit of weather data, so we've done all the analysis before it reaches their vehicles," said Robert O. Baron, President and CEO of Baron Services. "This streamlined, driver-centric philosophy helps drivers stay informed about perilous road and weather conditions, while being able to focus on safely reaching their destinations."

XM NavTraffic, powered by NAVTEQ Traffic, is the nation's leading real- time traffic service that offers the most comprehensive information and coast- to-coast updates every minute, ensuring that the driver has the latest and most detailed information at his or her fingertips. XM NavTraffic is now available in 80 major North American markets.
