I be reluctant to pay more money , consider I see other price hundred less . I recently move to a new state , and need something short of hijack a local to get around . I like to expandability of this middle of the road model . I especially like the portability of it , that I can carry it in my pocketbook or mount it on the car . although I find turn it on take a few hard push on the button-but it still be a great device . it have prove itself especially in traffic when I hit the detour button . it be well worth the money !!!
