Just got an email from Garmin with info on their new 2013 lines. They have some potentially nice features like directions based on street views rather than only street names which can be hard to find at times. The HD traffic in theory gives better traffic jam info and rerouting. In theory the screens are sharper and clearer and some views are given in actual street views. They aren't giving them away but they aren't as expensive as I thought they'd be given all the features. Here's the kickoff point.
