"The Garmin nüvi 2597LMT inherits many of the positive characteristics of its more expensive sibling while leaving an extra $130 in your pocket. But the question we ask every time we review a GPS is whether it's worth it to buy a dedicated device rather than using a free app on a smartphone. In the nüvi 2597LMT's case, the answer is yes—especially if you don't have, or want to use a smartphone."
