Garmin RV 660LMT 6.1” GPS with Lifetime Traffic and Maps

Journey across the country with confidence thanks to the Garmin RV 660LMT, an intuitive GPS navigator with features built specifically for large recreational vehicles. Custom-planned routes, traffic alerts, and points of interest are clearly displayed on the full-color touchscreen display, and voice-activated commands help keep your hands on the wheel while driving.

Avoid RV Hurdles

Low overhangs, rickety bridges, and steep hills can all pose a hazard for towering RVs, but the Garmin RV 660LMT takes the guesswork out of planning your trip. Just plug in the size and weight of your RV or trailer, and the GPS will create a route that caters to your vehicle’s limitations. It also takes into account preferred destinations and cities, and displays a directory of RV parks for end-of-day respite.

Hear Where You’re Going

Keep your eyes on the road, not the map, with the aid of spoken turn-by-turn directions. A natural-sounding voice gives you plenty of advance warning when you need to make a turn, exit the highway, or stop at your destination, so you can drive confidently and safely.

Natural-Sounding Navigation

If you’re giving directions to a friend, you’ll often point out landmarks like the gas station on the corner to help them know where to turn. That’s the concept behind Garmin’s Real Directions, which goes beyond simply naming street names and distances by pointing out local landmarks as waypoints and using more natural-sounding language to guide you to your destination. These intuitive driving directions are brought to life by Real Voice speech technology, which makes the GPS’s voice sound less like a robot.

Steer Clear of Traffic Jams

Re-route around congested roads with built-in traffic avoidance. If it learns of an accident, a construction zone, or a whole bunch of chickens crossing the road for undetermined reasons, the GPS will let you know in advance about any upcoming delays and suggest alternate routes, helping you arrive on time.

About Garmin

“Ideas can come from anybody,” notes Min Kao. While sitting around a shabby card table with fellow engineer Gary Burrell, the two formed the navigation company Garmin—a fusion of their first names—in 1989. Its goal was to take highly technical GPS technology and transform it into a product for the everyday consumer. These days, Garmin continues to hone their state-of-the-art navigation technology for cars, planes, boats, and wealthy meteors.

I just received this unit and have not had a chance to use it on the road. I anticipate that it will be a good unit like other Garmin units I have owned. It was easy to update and set up my RV specs so the device will know how to route me. I like the overall size of the 660 vs. the 760. I don't need a big screen to see what I need to see.
