very easy to use , right out of the box . very intuitive menu system and easy to use touch screen . if you want a very simply GPS Nav system , this fit the bill . there be no desktop application to speak of , which I would have like and you only get two warning about turn , one at the very last minute and I miss a turn or two at first . I would like a intermediate warning , but that come from have use another system . I get this for my son who get lose all the time and call I for direction - at all hour - and it have make a hugh differernt in both we life .
