About the Garmin Dash Cam 20

The Garmin Dash Cam 20 is a premium camera that will help monitor your vehicle while you are away from it and will capture your daily drives and commutes.  This useful unit by Garmin is one of their first Standalone Driving Recorders which has contributed to the brand’s success and later evolutions of dash cams.

The Garmin Dash Cam 20 will keep you safe and protected as a driver, capturing collisions, driving incidents, or any other unexpected activity that happens along the way. This Garmin Dash Cam 20 model is designed to suction to your windshield and sits discreetly behind your rearview mirror with concealable wiring for stealth and reliable mobile security system.

Hands-Free Security

With the Garmin Dash Cam 20, you can count on an easy-to-use device which will ensure you and your family stay protected on the road, especially to capture an accident, road hazard, or bumper-to-bumper collision. Dash cams are hands-free recorders designed to capture unexpected situations on the road and to protect your parked vehicle while you’re away.

The Garmin Dash Cam 20 will record automatically once you start your vehicle, so long as its proprietary 12-volt power cord is plugged into your car’s power source. The Garmin Dash Cam 20 is also equipped with an internal rechargeable battery which will allow you to remove the cam from its mounting to help you capture more detailed footage of an accident or roadside incident.

Trusted and Discreet

The Garmin Dash Cam 20 is ideal for defensive drivers who are looking for a reliable, GPS-enabled, and discreet camcorder to monitor speed, suspicious activity, or a scenic drive. The special features of the Garmin Dash Cam 20 give you more flexibility while driving, knowing your moves behind the wheel are accounted for, and any collision is well-documented.

The unit is compact yet capable of shooting 720p at 30fps. The Garmin Dash Cam 20 is powered by Garmin’s renowned GPS technology which features the date, time, location, and speed as it compares to the recorded footage. The Garmin Dash Cam 20 is equipped with an internal, high-sensitivity G-sensor which will easily identify a small or large impact, such as a car tapping yours in the parking lot or a hit and run outside of your home. This G-sensor-activated footage from the Garmin Dash Cam 20 is automatically protected and saved to a locked folder specifically for collisions.

Product Specs

Now let’s look at more details of the Garmin Dash Cam 20’s design and product specifications. The body measurements of the Garmin Dash Cam 20 are 6.6 x 6.6 x 3.7cm including a 2.3-inch LCD monitor that gives the driver easy access to change settings or review footage. The device is programmed to reduce its screen brightness while driving to prevent it from being a distraction.

This Garmin unit has a red light on the monitor to signal recording mode. With the Garmin Dash Cam 20, you will record AVI formatted videos with a max-resolution of 1,920 x 1,080, shooting at 30fps. This video resolution is complemented by a 720p or WVGA shooting mode. Your videos will save into small clips of about  255MBs to avoid large file sizes.

Reliable and Easy-to-Use

[amazon box=”B00HFMN46S”]

Special Features

This is a GPS-enabled device with the ability to stamp your clips with the location, time, and date. Your speed can be recorded as part of its computing system, which helps with liability in case of an accident. The comprehensive unit that has everything you need and some extras. We wish that you could turn off the audio capture as it records audio from inside the car—stereos seem to blast and interfere with the footage playback quality.

Video Quality

Video quality is consistent and clear, up to 1080p or 720p. Files are broken up into small clips for easier sorting and clip identification. The highlight is that this cam records high-quality night footage even in low-light conditions.

Design Quality

It is easy to use straight out of the box and only requires a clean glass surface to mount without issue. Sleek design and compact for discreet recording either as extra accident liability coverage or a vehicle security system. The 12v cord that comes with the unit is useless for discreet wiring; we suggest replacing this proprietary cord for a longer 12v power cord. 


  • Video quality is clear and HD
  • Parking mode feature
  • GPS tags available for video captures
  • Can record even when the car is not on
  • Sensitive G-sensor for accuracy
  • One-hour battery life when disconnected from the power source
  • Comes with 4GB micro SD


  • No MacOS interface
  • User reports of device freezing or quitting after several weeks of minor use
  • Poor customer service
  • High-end price point

Video Quality

Overall, the image quality is great and consistent with even lighting. License plates are clear during the day and its night vision captures many elements even without direct light.

Design Quality

Quality build of the camera itself, with powerful Sony technology. The major design flaw is that this unit only works with proprietary SD cards—it will glitch if you try to use other cards. The mount is cheap, which compromises the quality of the device.


  • HD video, crisp and clean footage
  • Continuous shooting mode while parked and vehicle is turned off
  • Many features
  • Easy installation and simple interface


  • Poorly designed mount
  • Only works with proprietary SD cards

The next dash cam on our list is the BlackVue DR650S-1CH. This unit is equipped with a Sony EXMOR CMOS image sensor shooting full HD video at 1080p/30fps. The BlackVue captures your driving routes with a 129-degree angle for comprehensive footage that records more than what is just directly in front of you. You can easily share and store your footage with a free Cloud service addition.

  • Parking mode great for motion detection
  • High-resolution captures
  • Easy to operate with quick-access buttons for muting or emergency recording

Our final dash cam to review is the Z-Edge Z3. This unit is the most accessibly priced on our list and we like it for its simple interface yet inclusive system design. Its impressive Ambarella A12 processor and OV4689 Color CMOS image sensor give you crisp and clear footage day or night.

Equipped with Wide Quad HD (WQHD) 2560x1440P resolution and a 155-degree viewing angle,  you can easily capture your trajectory and surrounding environment with stunning clarity.
