very nice setup , come with ac adapter , car charger and window suction mount . if you do not follow it be direction it recaluclate almost immediately with new one . huge pre-built datum base of gas station , restaurant , hotel etc. . type in any address and it find it . come with entire US build in , so you do not need to upload map to it as you travel to new area . only negative be that it be a little hard to read in direct sunlight and like all similar product it sometimes miss a more direct route . I be very impressed with it .
