Garmin Mini 3 vs 70mai M310: Garmin offers optional connected parking while M310 focuses on local phone access
Quick verdict
Garmin is the choice for the integrated polarizer, refined voice workflow and optional connected parking features. The M310 fits when you just want a hidden front camera with local app access for the lowest sensible cost.
Before you buy
Why, and what it costs you
Where these two really part ways
Garmin Dash Cam Mini 3 is the better match for “The windshield shows reflections of my dashboard”. 70mai M310 is the better match for “I want to record locally with no cloud plan”.
Where this comes from
This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.
The catch
Garmin Dash Cam Mini 3
With no screen, settings and local playback on your phone go through a compatible Garmin Drive app, and playing back footage stops recording and alerts. You don’t need a Vault plan for ordinary local recording and playback, and once setup is done the camera records without a constant phone connection. Neither GPS nor LTE is built in. To get location data, you would have to buy a separate GPS-enabled camera that sits in the Garmin multi-camera network. A compatible card and a parking-power accessory are also separate purchases.
The catch
70mai M310
It has no GPS and no rear-camera input.

Option A
Mini 3
Garmin, Mini 3
Dash Cam Mini 3
Garmin Mini 3 is a front-facing 1080p camera with no screen. It has a built-in polarizer but no built-in GPS or LTE, and you adjust its settings through Garmin Drive. Local recording and playback work without a Vault plan. Remote access is a different matter, since it needs paid Vault in a supported country, a compatible app, continuing power and internet Wi-Fi. The card and the parking power are bought separately.

Trade-offs
What each pick costs you
With Garmin Dash Cam Mini 3
Remote live view, Vault uploads and remote parking notifications all depend on an active paid Vault plan offered in your country, a compatible Garmin Drive app, continuing power and usable internet Wi-Fi. Local Parking Guard incident capture is a separate thing from those remote services. It requires suitable always-on power or the separate parking-mode cable. A timer, a low battery, temperature or network limits can end operation. Overnight coverage is not promised, and neither is remote browsing of the whole card gallery.
With 70mai M310
A supercapacitor design copes better with a hot cabin day after day than its internal battery does.
