Garmin Dash Cam Reviews & Buying Guide

You might be wondering what the major differences are between all the Gamrin Dash Cam models. While many of the Garmin dash cameras share the same dash cam housing and body, some have subtle and major differences when comparing them together.

Below we will give you a review of each Garmin car camera as well as a comparison with similar Garmin Dash Cam models.

Garmin Dash Cam 66W Review

Garmin Dash Cam 66WThis is the updated version of the Garmin Dash Cam 65.

The 66W dash camera from Garmin is one of their higher end models for their single cam dash cams. It records video at 1440P which is often referred to as Quad HD (QHD). With its wide 180 degree lens angle it makes it one of the widest among comparable dash cams, ensuring you will have total video coverage of the entire front area of your car.

It comes with all the driver assist type features like forward collision alerts, lane drifting warnings and “Go” alert which tells you when the car ahead starts moving again at a stop light.

With the voice control feature you can start and stop recording, take a picture or disable audio recording among other commands.

With its built-in WiFi you can remotely connect to the dash cam using your Android smartphone or iPhone. This will allow you to directly download videos to your phone to share with others, or to make dash cam setting changes. In order to use this feature you will need to download the free Garmin Drive app. If you don’t want to use your phone to interact with the Garmin 66W, you can do so directly on the dash cam using the 2 inch LCD screen on the back, making it easy to enable or disable audio recording for example.

Garmin Dash Cam 65 VS Dash Cam 66W

What’s the difference between the Dash Cam 65 and the Dash Cam 66W models? The 66W model is the newer one with some updated features not found in the Dash Cam 65. The added features on the 66W include: Garmin High Dynamic Range (HDR) Clarity which helps in low light conditions, larger microSD capacity of 512GB and the ability to be used with the Garmin Drive APP for Android and iPhones.

Garmin Dash Cam 56 Review

Garmin Dash Cam 56The Dash Cam 56 has many of the same specs as the Garmin Dash Cam 46. One of the main differences between the 2 dash cameras is that the newer Dash Cam 56 has a higher video resolution of 1440P, while the Dash Cam 46 only has a 1080p video resolution. Along with improved video quality it also has a higher photo resolution of 3.7 MP. It has a 140 degree lens angle, while it should be wide enough to capture most of the front of your car and the road ahead, it’s not as wide as the newer models, like the Dash Cam 66W that has a 180 degree field of view. However, with a wider lens angle you do tend to lose some quality and get a fish-eye type look, so having the 140° lens angle might be a better option for you.

Garmin’s Dash Cam 56 is their mid-range dash cam both in price and features. An upgrade from some of Garmin’s older dash cam models is the ability to use a larger microSD card with the Dash Cam 56. It will take a 512 gigabyte microSD card, that’s more than half a terabyte of video storage. Chances are you probably won’t need a memory card this big though, as the dash cam will record over all your previous videos when the card gets full, so you would actually be fine with a 8GB card if you only wanted a short video clip in the case of an accident.

The Dash Cam 56 model comes with WiFi built-in so you can use the Garmin smartphone app to connect to the dash cam directly on your phone, letting you download videos or make changes to the general settings.

Garmin Dash Cam 56 VS Garmin Dash Cam 55

What are the main differences between the 56 and the 55 Garmin Dash Cam models? There are not many. The newer Dash Cam 56 has a wider lens angle of 140 degrees, while the Dash Cam 55 has a lens angle of 122 degrees. The other main difference is that the Dash Cam 56 can use a large 512GB microSD card, much bigger than the 64GB capacity on the Dash Cam 55.

Garmin Dash Cam 46 Review

Garmin Dash Cam 46The Dash Cam 46 is the successor to the previous Garmin dash camera models: Dash Cam 30, Dash Cam 35 and Dash Cam 45. Like the other previous Garmin dash cams listed they all offer 1080p HD video recording, however the Dash Cam 46 has a wider lens angle of 140 degrees, while the Dash Cam 45 has a 122° lens angle and the Dash Cam 35 and Dash Cam 30 have a smaller 100° lens angle.

With the Dash Cam 46 you can use all of the same features found on some of the newer and more expensive models like Voice Control and Garmin Drive APP use with its built-in WiFi.

If you’re looking for the best budget Garmin Dash Cam model, this would be it in our opinion, as it is only lacking a few features of the higher priced models, like a wide 180 degree lens angle that is found on the Dash Cam 66W (the Dash Cam 46 only has a 140 degree lens angle). This shouldn’t be an issue if you drive a standard size car or pickup truck, since you won’t need a large field of view on your dash cam. This might be an issue if you’re a trucker driving a big semi and need to have an extra wide lens angle to cover the full front and peripheral of your big rig.

Garmin Dash Cam 46 VS Garmin Dash Cam 45

What are the major differences between the Garmin Dash 45 and 46 models? If you were to compare the 2 side by side the only thing that is different is on the Dash Cam 46 you have a wider lens angle of 140 degrees, while on the Dash Cam 45 it is 122 degrees. The 2nd thing is that the Dash Cam 46 has a larger microSD memory card capacity of 512GB, while the Dash Cam 45 can take up to 64GB. Both models are usually sold around the same price, so we would recommend buying the Garmin 46 over the Garmin 45.

Garmin Dash Cam Mini Review

Garmin Dash Cam MiniGarmin has already had a line of small and discrete dash cameras on the market, but the Dash Cam Mini is even smaller. Garmin has photos of the dash cam next to a car key and the Garmin Mini is shorter than the car key, giving you an idea on just how compact the camera is.

Even with its small size, the Mini has many of the same features as the bigger and more expensive Garmin Dash Cam models.

With built-in WiFi you can use the free Garmin Drive app to connect your Android phone, iPhone or tablet directly to the Dash Cam Mini. Once connected you can download videos on to your phone and share them online. Because of the small shape of the Dash Cam Mini, you might want to mount it up and behind your rear view mirror, which is out of sight and sometimes hard to reach the buttons on the camera. Using your phone synced to the Mini, you can make all the dash cam setting changes right on your phone without having to reach up and behind your rear view mirror.

The Mini dash camera records in 1080p HD video and uses a 140 degree lens angle, which is somewhere in the middle in terms of wide and narrow, as the older models only had a 122 degree field of view and the newer models like the 66W have 180 degree lens angle. 140 degree lens angle should be wide enough for most cars and trucks.

An upgraded feature on the Mini compared to the older models is the larger memory card capacity. You can used a 512GB microSD card in the dash cam and this will give you nearly 50 hours of video storage, although this is not necessary unless you want to archive video. The dash cam will automatically record over the old files and keep recording.

Best Memory Card For Garmin Dash Cam

Memory Card for Garmin Dash Cams
Buy on Amazon

We recommend getting a “High Endurance” SD memory card that can handle video recording and the frequent overwriting of old video files like you have on a dash cam. It should be at least a “Class 10”, which is the write speed of 10Mb/s.

The Samsung PRO Endurance series of microSD card is a good choice for Garmin Dash Cams.

You will need to format the memory card before you begin to use it. To do this, simple insert the microSD card into the slot in the dash cam. Once it’s in, power the dash cam on and go to the basic menu settings and go to: “Settings > Camera > Format Card” and select OK to format. This should be done about once a month or so to ensure that you don’t have any corrupted files (be sure to backup any video you might want to save before doing so).

Using Garmin Voice Commands

Voice control commands will work with the following Garmin Dash Cam models: 54, 55, 56, 65W and 66W

How to use the Garmin Dash Cam Voice Commands, here is a list of commands:

To activate the voice control feature say:

“Save Video”
