All of the other good reviews are spot on! I mean...its a real USA Road Atlas...just like the paper book ones...only better! You can set routes, re-route if necessary the same route, check mileage within a route, check certain "insets" for a major city, change route line colors and line types and much more. I just love it and cant believe that I dont miss the paper book one that always...gets wet, torn-up, lost in the car, out-dated, etc.....but surprisingly I dont miss it!!!
