for the money I do not think you can do better than the Garmin c330 have to offer . I purchase a couple and return of other prior to come back to this unit and for ease of use and accuracy , nothing beat it . the only knock I have on it be it be size compare to some of the other with the same size screen . it would be much easier on air travel if you could pack it away in you laptop case like some of the other . I recently use it on a vacation which involve several move to different place on the west coast and this thing be a super time saver , not to mention the tension of plot out you trip and try to make head or tail out of those internet provide drive direction .
