Free Lifetime Map Updates

Roads change. Businesses open and close. nüvi 66LM enables you to keep your device up-to-date with the latest maps¹ that Garmin has to offer, with no fees. Map updates also contain fresher points of interest, so your nüvi can give results that are more relevant and have greater accuracy. With increased road detail and more points of interest, new maps could be larger in size; as a result, map updates may require a microSD™ card (sold separately).

Navigate Complex Interchanges with Ease

nüvi 66LM has lane assist with junction view that displays upcoming junctions and uses brightly colored arrows to indicate your proper lane.

Easier to Search, Quicker to Find

nüvi 66LM has a search field that makes it easy to find addresses and millions of points of interest, in a single place. Now, simply enter a category (like “pizza”), an entire address (“1234 Sycamore Lane, Anytown, USA”) or a proper name (“Starbucks”) and nüvi 66LM quickly returns your results.

More Information Right on Your Map

No need to search for a hard-to-read or nonexistent sign; with a glance at nüvi 66LM, you’ll see your current street. nüvi also displays speed limit, current speed and estimated arrival time.

With the Up Ahead feature, you can easily find places you want – like restaurants, gas stations, ATMs and shops – without leaving the map. Best of all, Up Ahead is customizable, so you can always know the location of favorite destinations along your route.

You can access Up Ahead and other useful information from the map tools panel. Conveniently remain on your map screen and still find places Up Ahead, change the volume and more.

School Zone Warnings

nüvi 66LM issues an audible alert and displays an onscreen warning whenever you approach a school zone.

One-stop Device Management

Use Garmin Express to keep your nüvi up-to-date. Garmin Express makes it easy to update maps and software, transfer favorites to and from devices, and install free custom vehicles and voices.

    Does what I wanted I have had it a couple of weeks, logged about 1,500 miles and been in 3 states. So far I have been very happy with this GPS.On the negative side the manual that comes with it is pretty useless. You really have to go to the Garmin site and download the manual. That one is fairly good, but I have still had to figure out several things by trial and error. For example it doesn’t explain how turning on and off power works very well. But it turns out that if it is powered from an outlet that turns off with the ignition, it turns on and off with the ignition, so you never have to touch the power button if it is just used in the car. (If you want to leave it on so it records your stopped time on a trip, you have to set the display not to turn off and then cancel the turning off display that comes up when you turn off the ignition.)Downloading Garmin Express, updating the firmware and the maps worked well. (I got a failed message once, but I don’t think it really…

    Great Device But Less Than Intuitive Activation A long time Garmin user, I just upgraded from a 765. Some observations: Upon (prompt) arrival, a Garmin sticker on the face of the device claimed it is ready to go out of the box. Sadly untrue. Upon turning it on, the 66LMT locks on a screen displaying a screen suggesting (not clearly stating) to go to Garmin support. The 66LMT did not function prior to going online and downloading software updates and maps. With my U-verse connection this took about one hour. Once the download completed, the device just “sat there” with the same “Garmin Support” screen. A reboot – not stated in the Very Unclear quick start sheet – was required.Once done, the 66LMT works like.a champ. The 6-inch screen is delightful. Deviating from the recommended navigation no longer brings a voice droning “RECALCULATING”. Nice. Navigation is enhanced with icons along the route showing the location of restaurants, gas stations, etc. a convenience which, if annoying, can be deactivated. Programming in…
