Easy to use right out of the box !! once I upload the latest map , enter several location for future use I start use it the next day . I always end up close to the desire destination even if it have little `` alley be '' for access . the traffic update be nice to see in yellow or red accordingly along with a delay clock to the top left . the only downside I have notice -lrb- but nothing for I to return the unit about -rrb- be that the indicate speed be a `` on and off '' thing . sometimes it be accurate at a couple other time I would be drive 45-50 mph and the unit say I be go 25 or some other random number . the unit have show I drive to the side of a road before but I be underneath of a main highway for the area so not sure what that be about . overall a great deal for a great product !! would recommend for the professional or one constantly need direction . also , Garmin be the only gp unit I have find to be usable in Hawaii due to the way we put address ... . 45-xxx , 96-xxx 91-xxx -lrb- whatever street -rrb- .
