Garmin Dash Cam 57 Review

We learned the value of using a dash cam and wanted one for RVing. We selected the Garmin Dash Cam 57 for our truck and travel trailer. Check out our review.

Why Use a Dash Cam

We sometimes find that driving an RV can be a bit challenging. Our combination of a 3/4 ton pickup and travel trailer are relatively heavy. It takes longer to accelerate, merge, or stop than it would in a car. And yet, drivers often merge in front of us with limited space. After a highway accident in one of our cars, we discovered that the kind of video a dashcam can provide can be very useful. A dash cam won’t prevent an accident. However, should you be in one, having video that shows the incident could be helpful.

Another reason to use a dash cam might be to get video footage to share. Since we create RV travel YouTube videos, some road trip videos might be a good addition.

Selecting a Dash Cam

After getting a dash cam for one of our cars, we thought it would be good to have the same for our truck. Initially, I planned to just move the dashcam to whichever vehicle we were going to use for a road trip. However, the dashcam we had could only be installed in one vehicle. It required a special mounting bracket and wasn’t available for purchase.

A few of the things that seemed important to us for a dash cam are:

  • Ability to use the dash cam in more than one vehicle
  • A wide field of vision – so that you can see cars merging into your lane
  • Ability for the dash cam to automatically save video related to an accident
  • The ability to capture high quality video – good enough to include in a YouTube video

How Does a Dash Cam Work

A dash cam is a small camera mounted to the windshield of a car or truck. In some cases, a second camera is mounted on the rear window to capture footage from the rear of the vehicle.

A dash cam typically records video on a loop. The camera uses a small memory card, often a micro SD card. It records short sections of video. Once the card is full, it starts overwriting older recordings.

Some dash cameras have advanced features like incident detection that will automatically save video just before an after a detected incident. This content doesn’t get overwritten like the rest of the recordings.

Why Did We Select the Garmin Dash Cam 57

Several manufacturers make good dash cameras. The things we liked about the Garmin Dash Cam 57 are:

  • Small size that doesn’t interfere with our ability to see the road
  • High definition video. The Garmin 57 records in 1440p which provides great video quality. It is also recording at 60 fps (frames per second) which enables the video to be smooth compared to 24 or 30 fps.
  • Incident detection. When the Garmin detects a significant bump or fast movement, it automatically saves a section of video just before and after the event.
  • Updated safety features. Our older vehicle doesn’t have lane departure or forward collision warnings. It’s nice that the Garmin enables us to get those safety features without having to upgrade our vehicle.
  • A second vehicle mount is provided. The Garmin dashcam has a second magnetic mount so that we can easily use it in more than one vehicle.

Does Garmin Make Other Dash Cams

Garmin has four dash cams in their lineup. The 47, 57, and 67W are all similar. Key differences include the video quality and the width of the viewing angle. Garmin also makes a very small dash cam, the Garmin Mini 2, which is about half the size of the others but has no screen.

How to Install the Garmin Dash Cam

Three of the Garmin Dash Cams install the same way. The 47, 57, and 67W are pretty easy to install. Here are the basic steps.

How Well Does the Garmin Dash Cam 57 Work

We’ve had the chance to use the Garmin Dashcam 57 on several trips. So far, it works great.

The Garmin Dash Cam continuously records video as you drive. It saves the video in one minute files. Once the mini SD storage card is full, new video begins to replace old video. The high definition video is clear. While the 140 degree field of vision is pretty good, you might choose to opt for the full 180 degree view available on the Garmin Dash Cam 67W.

If the dash cam detects an incident, like a short stop, it will automatically save video from before and after the event.

The included safety features are nice. When a potential safety hazard is detected, the dash cam emits an audio alarm and the screen shows a message for the warning.

The three alerts we appreciate are:

  • Traffic is Moving
  • Lane Departure
  • Forward Collision Avoidance

If you want to see these alerts demonstrated, check out our YouTube video review.

It’s great that Garmin included a 16 GB mini SD card with the unit. About the only improvement we would like to see is to have more storage included. We plan to upgrade to a 256 GB card.
