The Garmin Dash Cam Mini 3 is one of the most compact dash cams you can buy today, with a chassis that measures just 2 inches wide by 1.5 inches tall . This tiny camera is designed to hide discreetly behind your rearview mirror, making it nearly invisible from the driver’s seat. The trade off for that small size is that there is no screen, so you will have to view footage via the Garmin app or a computer. There is only one big Save button on the backside of the device, which you will not need to fiddle with much thanks to accelerometer powered automatic event saving . For drivers who value discretion and simplicity over bells and whistles, the Mini 3 is a compelling option.

Design And Footprint

The most obvious selling point of the Garmin Dash Cam Mini 3 is its size. At just 2 inches wide and 1.5 inches tall, it is small enough to tuck behind your rearview mirror without obstructing your view of the road . The camera uses a sturdy adhesive mounting system that keeps it shake free and securely in place. Unlike bulkier models with built in screens, the Mini 3 is designed to be seen and then forgotten.

The lack of a screen is a deliberate choice. It keeps the device small, reduces distraction while driving, and simplifies the user interface. The only physical control is a large Save button on the back, which manually locks the current recording so it is not overwritten. For everything else, you will rely on the Garmin Drive app or simply let the camera do its job automatically.

Video Quality

The Mini 3 records in 1080p Full HD resolution . While this is not the highest resolution available on the market, it is generally sufficient for capturing the details needed for insurance claims, such as what happened during an accident and who was at fault. For reading license plates, the quality is adequate in good lighting conditions. However, users who need 4K clarity for plate capture may want to look at larger, more expensive models.

In daylight conditions, the footage is clear and detailed. At night, the camera performs decently but cannot match the low light performance of larger cameras equipped with larger image sensors. For the average driver whose primary concern is proving fault in an accident, the 1080p quality is typically sufficient.

Automatic Event Recording

One of the biggest advantages of the Garmin Mini 3 is its hands off operation. The device includes an accelerometer that automatically detects sudden stops, impacts, or collisions . When an event is detected, the camera automatically saves the footage and protects it from being overwritten. You do not need to press any buttons or remember to save anything after an incident. This feature is critical because the most important footage is often captured in the seconds immediately following an unexpected event.

Garmin Drive App

Because the Mini 3 lacks a screen, the Garmin Drive app is your primary interface for viewing and managing footage . The app connects to the camera via Wi Fi and allows you to preview live video, download saved clips, and adjust settings.

However, user reviews of the Garmin app ecosystem have historically been mixed. Owners of previous models like the Mini 2 frequently reported that the app connection can be spotty, slow to connect, and sometimes requires multiple attempts to establish a link with the camera . While Garmin has likely made improvements with the newer Mini 3, it is reasonable to expect that the app experience may still be less polished than what you would get from a smartphone native device. For users who prefer to manage footage by removing the microSD card and plugging it into a computer, this limitation is less of an issue.

What Is Missing

The tiny size of the Mini 3 comes with compromises beyond just the lack of a screen . There is no built in GPS, meaning your footage will not have speed or location data overlaid unless you purchase a separate accessory. There is also no option to add a rear camera, so this is strictly a front facing solution. If you want dual channel recording with front and rear coverage, you will need to look at a different product.

Additionally, the camera relies on an internal lithium ion battery rather than a supercapacitor. This can be a concern for drivers in extremely hot climates, as heat can degrade lithium ion batteries over time and potentially lead to malfunction.
