Has anyone seen the new Garmin Nav VI in the wild? Is it just an incremental improvement or does it offer a significant upgrade in visibility and routing options? They claim a new music streaming option, but I have no idea how well that works. My wife has a Garmin 590LM on her CanAm, which has a built in Pandora app, pretty cool, but I don't see that with the Nav VI. All I have seen to date are press releases.
