I buy the Garmin nuvus 1300lm 4.3-inch portable GPS navigator with lifetime map update . I have have it about a week and have only use it in area that I be familiar with . I do not want to even think about travel in a unfamiliar area with it and surely will not do that without a backup map . several time the direction could have get I into a awful situation . once I be direct onto a minor side street that would have make I miss my freeway entrance . another time I be direct onto the wrong interstate . if I have not be familiar with the proper route , no tell how much I would have have to go out of my way . other direction have be marginal . direct I to a street name , which be not post instead of a highway number that be and other thing like that . hopefully on the next update these thing will be improve . I do like some of the other feature that be not available on my old Garmin . my old Garmin be much better at give correct route , so I know they can do it . I be go to keep my new one and hope for the best . I will be travel with auxillary map though !
