   Best mobile navigator I’ve owned.
   I’ve been a TomTom customer for at least 30 years so I was very disappointed with my inability to find new product on Amazon. Tried a generic brand mobile navigator which worked OK but got tired of searching for audio route directions via FM radio signal. I chose Garmin as a last resort because I’ve always been biased toward the brand due to my preference for TomTom. After purchase I was quite surprised with the variety of features it has and how user friendly it is.• This model is the first mobile navigator I’ve owned which features Bluetooth compatibility. I really enjoy not having to sacrifice listening to my music playlist or music app to hear route instructions. THEY PLAY SIMULTANEOUSLY via my Android!• This Garmin even remembers locations I visit around the same time daily and issues a text prompt on the screen upon startup should I choose to visit the location prompted.• I also like the ease of inserting stops along the route to my final destination.• I originally feared the 6 inch screen would be too small since the generic brand screen of my previous navigator was huge. I needn’t had worried. The screen image is clear, offers needed map information without excess and audio guidance is precise.At first I couldn’t understand why I heard no audio instruction at all. (I’m one of those people who reads instructions as a last resort.) Took me a week to discover the mute/unmute setting in one of the menus.The only thing about using this Garmin that annoyed me was the windshield mount. I quickly replaced it with a compatible dashboard mount. Otherwise I have nothing but praise for the Garmin Smartdrive 66. Highly recommended.

   Worth the money.
   I use this Garmin daily and is a great product. I enjoy the combination of dash cam and gps map all in one. The size makes it easy to see. It has an alarm for forward collision and lane drift. I have used this Garmin on a 6 state vacation road trip and it’s accuracy was spot on. It also had a speed display of my vehicle and a posted speed for that section of road and the speed display turns red when I go faster than posted speed limit. The mount to window surface is secure and much better than earlier models. This Garmin is user friendly. Originally I had both a dash cam, and also a GPS which took up 2 locations on my windshield. The video from the dash cam part is great. This combination brings 2 items into 1 and keep my windshield view open and unobstructed. It is worth the price.

   Nice bright display, responsive touch screen, fast routing
   I got this to upgrade my very old Nuvi model. On those old GPS displays, the touch screen is SO frustrating and you have to really press and wait for it to recognize each tap. The old one was also frustratingly slow to recalculate the route if I detoured for something like a rest area or exit to get gas. The voice saying “Recalculating” becomes a running joke on long road trips.So, enough about the old one… the new Garmin models have a much more responsive touch screen just like cell phones. The processor in there is a lot faster to recalculate if you’re doing a detour (and without the annoying voice telling you about it). It also supports extra nav systems besides GPS which seems to help it be even more accurate (with 10 feet is usually what I got). The old one would sometimes lose signals in valleys or downtown between buildings and might show me a hundred feet away, but this model does a great job of showing where I really am.The voice navigation is amazing. It was so cumbersome to type in addresses on the old one but with the nice touchscreen, that’s a breeze, but what I really loved was being able to say “Okay Garmin, go to Walgreens” or something and then pick which one I wanted to go to from the list. I don’t know how thorough the database of locations is, but on my recent 3500 mile road trip, I rarely asked it for something it couldn’t look up. Fast food and gas stations are just fine, I even asked it to go to a Verizon store when we needed a new phone and it pulled up the nearby locations.My one gripe is probably about the connectivity to my Android phone. The Garmin Drive app works, but the GPS keeps wanting to change the volume of my phone on its own. I also connect to my car radio over bluetooth to play music, and I’ve setup the Drive app and GPS appropriately for that case, but it seems like when the GPS connects it wants to lower the volume of my phone (and thus how loud it plays music to the car stereo). I can turn it back up, but that only lasts until the next time I get going again. Very weird.I also had problems where the GPS would keep showing “Galaxy S8+ disconnected” over and over. I think that was the power savings on my old phone putting the Drive app to sleep… maybe? I disabled it from being able to sleep, but I haven’t driven long enough after that to see if it helped, and then I updated to a newer phone anyway so the jury is still out on whether that’s still an issue. That doesn’t concern me too much because when I’m driving, I don’t really need the GPS linked to my phone although, if I understand correctly, it can get data through that phone connection for even minor things like weather updates or road conditions that maybe the traffic data doesn’t get? Or using that tether for software updates too if I’m not within range of my wifi (which really only happens when it’s parked in the garage anyway).Overall I’m very happy I splurged for the update. I miss my old Nuvi 1390’s ability to connect to the ecoroute module plugged into the OBDII port so I could see the real time gauges right there on the GPS, but I do have a bluetooth dongle for OBD that I can use to see that on my phone. It was just handy because I’d use that whole ecoroute stuff on the GPS to keep track of my gas usage between fillups and it would show my MPG. I got an app for that now, it just means manually putting in my mileage instead of having the GPS already know that. It’d be cool if Garmin added a gas tracker app directly on the GPS… shouldn’t be that hard?

   Okay so I bought this cause it was on sale and it works awesome in the car…no complaints. Then I 3D printed a mount for my motorcycle. Yes I know it’s not meant for this but I’m not paying over $800 for a bike gps.I use this Garmin every trip. Bluetooth to my helmet and phone with Google drive so I get up to date traffic. 10,000kms and still amazing. When it rains I eather put it away or put a zip lock bag on it.If you need a GPS for whatever this one is fantastic.

   On top of purchase price you then have to purchase at great cost NZ Maps.

   Muy bueno, no tan intuitivo en su manejo como los viejos Nuvi y es algo difícil de registrar el dispositivo y actualizarlo via Wifi, yo lo hice todo con el cable USB conectado a la computadora y con la aplicación de garmin (garmin express). SI TRAE MAPAS DE MEXICO. 100% recomendado.

   No anuncio do produto está descrito que o adaptador 12V teria DUAS SAÍDAS USB e recebí um adaptador com UMA saída… O resto do GPS está OK.

   The item was excellent! Large, clear screen, easy to read, and provides all the important points of interest on the map.
