Bottom line

If you want the best portable car GPS system money can buy (and you're willing to pay for it), the Garmin nuvi 3597LMTHD is the hands-down winner. It's simple, elegant and crammed with every feature Garmin has to offer. It might be overkill for some drivers, though. Less expensive Garmin car GPS systems -- from the step-down Garmin nuvi 2597LMT (Est. $220) to the budget-priced Garmin nuvi 42 (Est. $110) -- navigate just as accurately.


Best-in-class navigation. In tests, Garmin GPS systems almost always navigate accurately (more accurately than other brands, some say). Still, GPS technology itself isn't perfect. In Jamie Lendino's test for, the Garmin nuvi 3597LMTHD did lose satellite contact in Manhattan's urban canyons, and it occasionally thought he was in an adjacent lane. But in CNET's test, it locks onto satellites instantly and navigates flawlessly despite San Francisco's tunnels and tall buildings. Its maps make it easier to negotiate tricky interchanges with features (like Active Lane Guidance) that you won't find on cheap GPS systems. The "LM" in the name stands for "lifetime map" updates, so you'll always be able to download the most recent maps.


Loaded with the latest Garmin frills. The nuvi 3597LMTHD is the only GPS system that includes lifetime HD Digital Traffic, Garmin's top-of-the-line traffic feature (you can get it on other Garmins, but it costs extra). Designed for quicker alerts and better coverage, it works well on New York City's major highways in's test, but "it's still not perfect," missing some congestion on secondary roads and city streets. Other features help you pick the best routes -- even complicated ones. For example, trafficTrends calculates routes based on predicted traffic flow. Auto Sort chooses the most direct route to hit multiple stops. Trip Planner lets you select your own order for multiple stops, set departure and arrival times, and more.

Ease of use

Pricey extras really make life easier. Here's where you really get what you pay for. The Garmin nuvi 3597LMTHD has the best screen of any car GPS navigator, reviews say -- a 5-inch, dual-orientation, multi-touch glass screen so crisp that it reminds testers of Apple's Retina displays (it can glare in the sun, though). Its elegant powered magnetic mount (no fiddling with a clasp or cord), voice commands, conversation-like directions (e.g., "Turn right at Starbucks," rather than just "Turn right on Elm Street") and intuitive search box (type in "movie theaters," and it shows the nearest ones) really make it easier to navigate, testers say.


So, is it worth a whopping $350? A basic car GPS system costs about $100. If you have a smartphone, you can navigate for free. So, are the Garmin nuvi 3597LMTHD's luxury features worth the luxury price? Yes, experts say -- if you're a road warrior who wants the smoothest navigation experience possible. But if you don't really need all the extras (or the price just isn't in your budget), you can certainly get an equally accurate GPS navigator for less.
