Customer Ratings & Reviews

I was very impressed with the ease of installation for the Garmin 66W Dashcam. The picture quality is excellent and the user interfaces, both on the Dashcam and the app, are very intuitive. The video is true 180-degree left to right and vertical video is sufficient to catch traffic lights, etc until almost under the light. Note that a memory card does NOT come with the Dashcam and must be purchased separately for the Dashcam to work. I got the largest that would fit, 512GB. I am happy with the ease of viewing videos via the Dashcam or the app. File transfer via the app to my iPhone was very lengthy. I won’t say it was slow due to file size; it just took a long time. I have not removed the memory card for file transfer on my desktop but would be a computer limitation anyway — not related to the Dashcam. My installation is very clean in my 2016 F-150. An adapter cable for the rear view mirror added a USB connection usable for the Dashcam. Works great, automatic power-on with ignition, and no wires in the way or routed to power outlet. Overall, I am very happy with the Garmin 66W Dashcam and would recommend it to anybody.

I am very happy with the video quality and the 66W is the reason. I wanted 1440 pixel resolution. It is instant proof of how poor many other drivers are. The camera needs a SD card (about the physical size of a finger nail). I had to spend one day solving the 32GB SD card limit. Larger capacity SD cards do not use FAT32. Larger SD cards must be reformatted with FAT32. The camera should be sold with an available choice of SD cards (size in GB) all pre-formatted in FAT32. Of course, the higher the capacity, the greater the cost. It is easy to connect to your laptop (use your cell phone charging cable, not the cables with the camera). You can view the MP4 files (about 1 minute each). Each is numbered and follows sequentially in the unsaved folder. Simply erase unneeded files, or allow the camera to overwrite. With a $33.00 SD card of 128 GB (reformatted to FAT32), I expect to get about 10 hours of camera time before overwriting begins. The save video option becomes less important with a high capacity SD card.

Awesome dash cam, easy to setup with app or without the garmin app. Quality is good to be a back dash cam. I currently have this a front dash cam with warning sounds off because it can't tell the difference from painted street lines to covered street lines/cracks. That's probably the only downside.

Easy to install and operate. Nice clear picture with an amazing wide view. Links easily with phone. Have the volume muted as the lane divergence warning was too sensitive. I chose to hide the unit from the driver's direct view, thinking the screen was always on and would be a distraction, but it goes off after a few seconds, so no need to do this!

It’s a good camera. Lane departure feature is not accurate and annoying. I’m not a fan of the mounting. Have to stick it in window and can’t move it from one vehicle to another. If there were other mounting features this thing would be great! Other than that it does what it says it does.

exactly what I was looking for especially with a WIDE view! be sure to set camera video quality to 1440 as it defaults to 1080. when parked remove camera or keep out of direct sunlight! otherwise the camera is exactly what I was looking for. HIGHLY recommended

The camera was very easy to set up and quick to install. The accompanying mobile app is also easy to use. The video quality is excellent, you can choose to record sound or not and display mph. The camera powers on and begins recording automatically when you power on your car as long as you leave it plugged in. Overall very pleased.

I got this as a replacement for my dash cam 55. Quality of the cam and the wide view is very nice. The onboard options are even better, you can update the firmware from your phone without connecting to the computer, the live view from phone is a nice feature. Option for a bigger memory card for more recording is a plus. The new feature to allow you to link u multiple dash cam so they can synchronize record with picture in picture is pretty cool.

Great picture quality and super wide point of view. If recording 4K get a fast high capacity microSD card (camera does not come with one). Optional parking mode cable is a must, get it professionally installed by Best Buy, fantastic service!

I have used several dash cams over the years. Rexing's failed within a year in the AZ heat as did a couple of other brands. Garmin has been the best as of this writing. Very easy to install and use.

Best dash cam I've ever used! I used a 128 gb sd card and is able to capture all of what i need it for. This one has a very wide angle lens and can also take voice command prompts to capture images and start time lapses. This also has a GPS to show the coordinates of where the recordings take place and also records speeds. Also has lane detection, traffic camera detection, collision warning, and traffic moving detection. Overall i love this dash cam compared to some of the other ones i've used

Very satisfied with my Garmin 66w dash cam! Very easy to set up and navigate on the website! High quality video!

Unfortunately one thing I don’t like so far is that it makes a beep when you’re over the lane’s line even if you’re not on top of it and/or merging into another one.

Does everything a dash is suppose to do and plus easy install. Garmin drive app works really well too. Great dash cam.

there are a lot of negative reviews on this and i think a lot is due to the problem with the time it takes to sync up with a phone. Normally im not in a HUGE rush to see anything so i don't mind the few minutes it can take to sync up. The quality of the images is good, but YOU MUST have the filter to make it work good on the front window, otherwise its all glare. For the cost i would expect them to add this filter with it.

We love it. The video quality is very good. And it's so small

compact size and alerting is good. video quality is great

I had a hit and run while my car was parked at the air port. Now I can see who hit me.

I was able to simply plug it in, hang it on the window, and quickly download video and pictures as needed from my dash cam.

Great camera just takes a little time to get used to it then you want me to do nothing but just sit back and enjoy it I have to micro SD cards that I switch back and forth so I could save my videos and pictures that I want to save
