Bests & Worsts Reviews from Amazon

Be warned: by Microsoft's own admission, there is no way to update the maps provided with this product and Microsoft doesn't much care about them anyway (deferring to an unnamed "third party" when confronted with inaccuracies). That wouldn't be a problem if care had been taken in ensuring that the product ships with accurate maps, but it doesn't. Though this is a recent release, its map data (again by Microsoft's own admission) is almost a year old. Worse than that, it contains fatal inaccuracies that are older: for example, the I-95, I-295, and I-405 in Maine are in the wrong places and don't reflect a "redesignation" of exit numbers that took place there last year. There's really nothing here that one of the many online map sources can't provide for free -- except interstates in the wrong place! (MapQuest gets Maine right.)
