Garmin StreetPilot c580 GPS with MSN Direct in da house, er car

I boxed up the Q1B to ship back to Via today and immediately got another device in the review queue. Thanks to the folks at Garmin, I have a loaner c580; this is the portable GPS device that has the MSN Direct service integrated in as well. That integration adds real-time traffic, weather, and movie times for when you're on the road. As I look at the box, I see support for hands-free calling, voice announce directions, MP3 playback and more. Sounds like it has all the bells and whistles. Before I really hit the road for a full review, be sure to comment with any specific questions. I have a built-in nav system in the 2006 Toyota Highlander Hybrid, so it should be interesting to compare the two units.
