when the item work it be great . I have have problem from the first . screen go off . part of picture not there . after 2 hour it just go out . it do not like heat . if you get one without problem it work great . if you follow what it say to go you will not get lose . it do sometime go to place in some different way then I would go . Garmin have state they would fix or replace it if what they tell I to fix it do not work . I would buy again maybe . I have hear of greater problem with other that be not Garmin .
