excellent product , do everything it be advertise to do . I especially like the 3d view , much more followable -lrb- if that be a word ! -rrb- . it be very easy to use for those who be novice to the gp mapping world . the only drawback for I be that it be not waterproof and I intend to use it on a motorcycle . hence I have to trade it in for a more rugged model . but for those who do not intend to use it in the rain , by all means this be the product for you .
