I have the 2010 and it is a Pain in the a$$ because I have trips where I cross from one disk to another. So If you are doing a cross country trip, you have to pick a point near the end of the map enter that location, get to there, stop the car, put in the new disk, let it sit for 5-10 min and then go on.... That is why I keep my 2009 disk in the car at all times.
