The Good The Garmin Nuvi 3597LMTHD boasts a premium design with a sharp 5-inch capacitive screen and a thin metal chassis. Voice command makes the already intuitive interface easier to use on the road. Search-based destination input and natural spoken directions smooth things further.

The Bad The Smartphone Link feature doesn't really do anything aside from serving as a portal for additional paid services.

The Bottom Line The Nuvi 3597LMTHD continues to refine Garmin's brand of navigation with premium design and one of the best interfaces in the business.

After years of reviewing PND after PND, it's hard to get excited about a GPS device's physical form. However, the Nuvi 3597LM has managed to capture my attention with its glossy, black face and slim chassis.

The Nuvi looks slimmer than it actually is thanks to tapered edges that visually shrink the device's profile and make it easier to slip in and out of a pocket. Strategically placed black panels on the top and bottom edges also aid in visually slimming and classing-up the silvery metallic device. However, at its thickest point, the 3597LM is about as thick as the rest of this class of portable navigation devices.

The hardware
On the face of the Nuvi 3597LM, behind a capacitive glass panel, shines a crisp 5-inch TFT screen that is gorgeous. The 800 by 480 pixel resolution isn't as hypersharp as today's Retina-class smartphone displays, but its brightness and clarity are better than on nearly every other portable navigation device that I've ever tested. Being capacitive, the glass can register swipes and pinches as well as taps, and the Nuvi's interface takes advantage of these new input types. Just to the right of the screen, you'll find a pinhole cut into the glass bezel for the Nuvi's microphone.

The Nuvi features an internal accelerometer of some sort and its display can rotate between portrait and landscape orientation for the maps and menus.

Along the bottom edge of the Nuvi 3597LM is a small slot where a microSD card can be inserted to increase storage for downloadable maps and updates.

On the back panel is the Nuvi's single physical control: a power button. Tapping the power button suspends the Nuvi, shutting down its screen. Tapping it again causes the device to instantly reawaken. For those times when you need to shut the Nuvi down for extended periods of time, such as when packing it for travel, holding the power button for a few moments will totally shut down the device.

Also on the back panel is the Mini-USB port for charging the Nuvi 3597LM and updating the software with the aid of an Internet-connected computer, Garmin's proprietary 12-pin dock connection, and a very tiny integrated speaker behind a drilled grille.

The integrated speaker isn't nearly loud enough to be heard over the levels of road and wind noise and car audio that you'll experience while driving, but it doesn't need to be because the 3597LM's cradle-and-suction-cup mount features a speaker of its own that is plenty loud. The cradle attaches to the Nuvi with a powerful magnet, for easy one-handed mounting and dismounting, and attaches to the windshield or other smooth, nonporous surfaces with a strong lever-activated suction cup.

The last bit of hardware is the power cable, which converts your car's 12-volt power source into a 5-volt charge usable by Nuvi and connects to the cradle with a Mini-USB connection. The cable also powers the cradle's loudspeaker and integrates the FM/HD Radio antenna that receives the free, lifetime over-the-airwaves traffic data that transforms the Nuvi 3597LM into the Nuvi 3597LMTHD that I tested.

The upside of integrating the antenna into the cable is that it makes a thinner device possible. It also means that with no cable, you also get no traffic data, though the Nuvi still remains usable for navigation for a few hours via its internal battery.

The firmware
The 3597LM features wireless connectivity with a smartphone via Bluetooth. That connection enables hands-free calling using the PND's microphone and speakers, and a feature called Smartphone link, which we'll get to momentarily.

Upon pairing with a smartphone, the Nuvi will attempt to sync the phone's address book -- although just the numbers, not the addresses -- which can be accessed via a phone menu. The reasoning behind Garmin's decision to hide the phone menu under the Apps subcategory rather than putting it in the main menu like in previous Nuvi models escapes me. Fortunately, there is an easier way to access those contacts.

This Nuvi includes a great voice command system that is truly hands-free. It isn't even activated by a button, instead being awakened with a customizable spoken command -- by default this is, "Voice command."

When the Nuvi hears you speak that command, it responds with onscreen and audible prompts that guide you through spoken address input, points-of-interest search, and dialing contacts for hands-free calling. The system is remarkably accurate; I particularly appreciated the almost conversational way that I was able to speak to the device, inputting full addresses in one go rather than wading through a half-dozen prompts.

I also appreciated the conversational tone of the Nuvi's spoken turn-by-turn directions, which call out landmarks and use natural language. Rather than say, "In a quarter mile, turn left," the Nuvi may say, "Keep straight past the hotel and turn left at the traffic light." When on the highway, the Nuvi may tell you to "Stay in any of the three left lanes" when approaching an exit, which helps me, the driver, to better avoid last-minute hustles to get in or out of a valid lane for the trip. It also meant that I didn't have to watch the screen for lane guidance, which allowed me to keep my eyes on the road.
