While the map software is 2013, they still use some pretty old map data. This is the case with pretty much all map software - Garmin, Mapquest, Google, Microsoft Streets & Trips, you name it - they're all going to be pretty outdated. Neither of these have in the 2013 version discovered that the intersection closest to my house was changed from a 5-way to a 4-way -- almost 3 years ago. They all want me to drive through someone's lawn.
Why? Money, of course. Using up-to-date maps would be terribly expensive, so they mostly rely on older free maps.
