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?

Much improved when compared to my older Garmin unit.
The DriveSmart 76 is my second Garmin GPS. My first one was the DriveSmart 61 that I bought in 2018. The 61 and the 76 look virtually identical. They both have the same screen size (6.95” diagonally), and they both have the same screen resolution (both screens look very sharp). I’ll be comparing the two in my review. My older model 61 still works fine after six years of use. So, you may ask, why did I feel the need to upgrade to the model 76? Quite simply, the voice recognition on the model 76 is significantly better. Voice recognition is very important to me. I don’t use my GPS while mounted on the windshield or the dash. In my opinion, the moving-map display on a GPS is a major distraction. I see people all the time weaving in traffic because they’re playing with their phone and not watching where they’re going. A few years ago, a driver who was texting crashed into my car. I don’t want to be guilty of that kind of behavior. So when I’m driving, I keep my eyes on the road and my Garmin GPS laying facedown. Because I depend entirely on verbal commands from the GPS when driving, the voice-recognition of the device is very important to me. Voice Recognition: To begin a verbal search on my older model 61, say “Voice Command.” How well does it understand my request? On a scale of 1 to 10, I’d give it a five (5). Some searches are OK. But about half the time it thinks I'm requesting something completely different. This happens even though I’m speaking very clearly and distinctly, or even after repeating the name of a business or a restaurant numerous times. Quite often, the verbal search results on the model 61 are ridiculous, frustrating, and so bad they’re comical. To begin a verbal search on my new model 76, say “OK Garmin.” How well does it understand my request? On a scale of 1 to 10, I’d give it an 8.5. It’s not perfect, but it’s significantly better than the model 61. As a test, I drove around one day with the 61 and the 76 side-by side. The model 76 can usually understand my search request on the first try. However, there were many times when the model 61 failed to understand the exact same request after numerous attempts. Search by Category: Depending on the name of the place you’re looking for, some searches are easier to find on the model 76 by category. For example: You may be looking for a specific German restaurant. If the GPS is having a hard time finding the name of a particular restaurant (because of your pronunciation or some other reason), try requesting “German Restaurant”, followed by the name of the city and state. If there are any German restaurants in the requested area, you’ll be presented with a list to choose from. Improved Voice: Another thing that I like better about the model 76 is a much improved voice. For “American English” (with full “OK Garmin” capabilities), Garmin uses a female voice named Zoe. It’s more clear and natural-sounding than the voice on the model 61. Battery Life: The 61 and the 76 both have a rechargeable internal battery. When fully charged, you can expect the battery to only last about an hour. That’s not very long. But keep in mind that the unit will be plugged into a 12V outlet in your vehicle when in use. The internal battery is really only necessary to power the unit while it’s connected to your computer with a cable (or Wi-Fi), while downloading updates and maps. I find it very helpful to use an AC adapter when downloading updates. Amazon sells them, and they’re not expensive. What you want is an AC adapter that plugs into a standard home 110V AC wall outlet, and has a cigarette lighter socket that supplies 12 volts DC. This allows you to charge the GPS in your home, and also provides you with all the time you need to download updates without running out of power. Tip: When you press the power button on the model 76, it turns off the display and it appears to be off. Not so. It’s only sleeping. To completely turn off the unit and preserve maximum battery power, hold down on the power button. After a few seconds the screen will ask if want to turn off the device. Tap “OFF”, and the unit will be turned completely off. Note: When connected to an outlet supplying 12 volts, the internal battery will still be charged even though the unit is turned completely off. Note: After about five years of use, my model 61 got to the point where it wouldn't hold a charge for more than a few minutes. I replaced the internal battery myself. But to do so, you need the right tools, and you need to be comfortable with taking it apart and putting it back together. I expect the longevity of the model 76 battery to be about the same. Model 76 Likes: 1. Big and clear display. 2. Much improved voice-recognition. 3. Once you learn a few basics, the operation of the unit is pretty intuitive. 4. It has a more pleasant and natural-sounding voice than older models. 5. Free map and software updates. 6. You can sync this device with your mobile phone for phone calls and music. However, I use my model 76 as a stand-alone device. Model 76 Dislikes: 1. The voice-recognition is very good, but it’s not perfect. There are times when I have to repeat or rephrase my request. 2. The one-hour battery life isn’t any better than my older unit. 3. Garmin only provides one voice selection for American English that has all of the “OK Garmin” capabilities. Again, the voice is pleasant and natural-sounding. But it would be nice if they offered other voices for download. 4. Battery replacement could be easier. Garmin knows that no rechargeable battery lasts forever, and that at some point it'll need to be replaced. The internal battery in my model 61 needed to replaced at five years. I did it myself, but it required the right tools, and I was OK with taking it apart and putting it back together. Not all consumers may want, or otherwise have the skill to tackle the job. In five years or so, I expect the model 76 will also require a new battery. Garmin, why not make it easy for the consumer to replace the battery without the need for any tools or skill when the time comes? Final thoughts: I like the Garmin model 76 very much. In fact, I sold my model 61.

Best of both worlds (dedicated vs. smartphone)! Google traffic/POIs, Garmin nav
I've been using this for over a year, and it's been fantastic. In case this review is appearing in the wrong place (because for some reason, Amazon is grouping reviews for different Garmin devices together), I'm reviewing the Garmin DriveSmart 86. If you think this is your dad's Garmin, you couldn't be more wrong. It merges the best aspects of smartphone navigation (traffic updates, points of interests (POIs)) with the excellent Garmin features. If you don't drive a lot or don't use a GPS a lot, you don't notice the problems with smartphone navigation. But use it enough and you'll notice how much better Garmin is. Do I always think Garmin navigation is always better? No. But on average, I feel 60-70% of the time it's better. Now, if I'm in a heavy traffic situation or if I'm in a very unfamiliar location, I will run both at the same time and then decide based on my prior knowledge of the area and my instincts to determine which one to trust at any given moment. Here's some pros for the Garmin. You don't need any cellular reception in order for the navigation to work. This came in quite handy when I was in areas of poor reception like rural areas. Sure, with smartphones you can download maps but that requires some preplanning. The Garmin is still the best for letting you know ahead of time what lane you should be in which comes in handy when you need to switch multiple lanes multiple times in short succession. You can also have both the map and some text turns at the same time so you can see ahead of time what your turns will be. The 86 has a fast CPU so it doesn't get laggy like older Garmins. It looks great in both vertical and horizontal orientations and for the first time, I feel like the 86 works better in the vertical orientation because of the better viewpoint. The screen is beautiful. The response and touch is great. If you connect the 86 to your smartphone via the Garmin Drive app, you now get all the benefits of the smartphone with realtime traffic (provided by Google I think) and the much bigger database of points of interests. So if you ever thought the Garmin POIs were too small or out of date or if you thought the search engine in the Garmin device was too weak, you can search in the Garmin Drive app and push that location to the Garmin GPS. Same for traffic. Garmin real-time traffic was often too slow to update but now with Garmin Drive, you never miss out on traffic alerts. If it's in Google, you'll find it in Garmin Drive. Of course, if you use Garmin Drive, you will need cellular reception but only while you're searching initially for the location. Once the Garmin is navigating, no cellular needed. The Garmin has so many options on how to pipe the audio. You can separate what type of audio goes through the Garmin and what goes through your car. So if you want phone to go through the car but nav instructions to go to the Garmin, you can. If you want everything to go to the car, you can. If you want phone and music to go to the Garmin but nav instructions to the car, you can. I send nav audio to the Garmin and everything else to the car because I've always hated the up and down volume when smartphone nav sends out nav instructions. You don't have to worry about draining your phone battery. It's easy to use the phone while navigating on the Garmin. The Garmin now uses USB C and the car charging cable also has a USB passthrough if you wanted to charge something else. The only negative (and I don't know if the situation has changed) is that at the time, there was no dashboard mount for the 86. Only the included window mount. The window mount is good but if you don't regularly clean the windshield and the mount, the Garmin will fall off.

Horrible Bluetooth and phone support
Updated score to one star from two stars. This device is Bluetooth is one of the worst I've ever seen. It takes ages to connect to Apple and Android devices. Every time you leave your car and come back it will have a problem connecting it doesn't seem to be a fix either. You have to restart your device, restart your phone, clear the app data, turn the Bluetooth, on turn it, off forget the device, and re-pair the device. I've had cheap $20 Bluetooth devices that have better connectivity than this. You need to be able to pair Bluetooth so that you can enter addresses from your phone, trying to enter an address into the devices self is slow and clunky. If you're only buying this to enter addresses directly into the device I would avoid because it just takes too long and does not work well ********** I do a lot of driving to different addresses and wanted something other than Google Maps which would constantly give me bad voice directions. I don't have an in screen Dash navigation system so I wanted something I could just have up to look at the directions instead of listening to them from my phone, or having Google Maps displayed on my phone if I am playing music. As navigation it does pretty much what I want it to do. The only issue is the absolutely terrible support with phones. Trying to search for an address on the unit itself is cumbersome and annoying, and much quicker to do it from the app and send that to your phone. Unfortunately it always loses Bluetooth connection and will not connect. You have to turn off Bluetooth turn it back on. Unpair and repair. Turn the GPS off turn it back on. This happens twice a day at least for me. I tried a different cell phone I had and had the same issues. If that app worked and the Bluetooth worked I would probably keep it but as it stands now it's far too annoying everyday to mess with the connection so I'll probably be returning this

Excellent GPS System
This is exactly what I needed. Was tired of relying on cell service to find address. I am a service technician and the voice control along with the Alexa integration is excellent. Gives phone alerts and hands free access from my personal phone. I live in area without alot of radio stations. The Alexa integration allows me to access all my listening needs and GPS services are spot on. I would highly recommend this unit to everyone.
