let I begin by say that as a straight up GPS , this unit work fine . I have own it for just over 6 month and it get I from point a to point b flawlessly . the problem be that I upgrade to this unit from a older Garmin GPS specifically for it be traffic feature . since the day i purchase this unit , it have \* never \* -lrb- and I mean this literally -rrb- alert I to traffic in any way that help I to avoid traffic , and I live in a suburb just outside of NYC where traffic and alternate route abound . every once in a while it will alert I to `` traffic ahead '' as I be drive into traffic , and have already pass the turn I could have make to avoid it . and I be talk about major highway , not just backroad block up by a car accident . what be perplexing about this be that clearly the technology exist to detect traffic real-time . Google map do a very good job with this . why Garmin have not be able to incorporate this adequately into they product be a mystery . so essentially , I through away money on a second gp . bottom line : save you money and buy the cheaper non-traffic update model .
