The all new 2009 Acura RL - which was also unveiled today at the 2008 Chicago Auto Show - will be offering XM NavWeather as a part of its AcuraLink service.

Acura is XM's first automotive partner to debut the XM NavWeather service.

The real-time, personalized weather tracking service is delivered directly through the Acura RL's in-dash nav system, and uses XM's "Threat Matrix" technology which provides alerts on weather threats (like hail, floods, tornado and storm warnings).

XM NavWeather also provides multi-day forecasts based on weather monitoring stations across the U.S.

The 2009 Acura RL also unveiled a new feature called "XM Note."

Developed by Acura, specifically for use with XM Satellite Radio, Note lets users record 10 seconds of live XM music along with the name of the artist, song title, and even the XM channel name that can be referred to at a later time. It's essentially a "tagging" feature built into the vehicle. Acura's Note also allows you to store up to 30 songs through the audio system.

The RL comes standard with the all-new Note function for XM.
