It's a fantastic unit. You can choose Fastest, Shortest, No Tolls, various vehicle typre (for access to different roads if you have a truck), pedestrian (for use in cities it ignores one ways). The maps and points of interest (over 2,000,000) I've found to be very up to date. Loaded with all 50 states. The size of an ipod...makes for easy carrying from vehicle to vehicle.
I love mine!
