Garmin Dash Cam Mini 3 vs Garmin Dash Cam X310: Mini hides away without a screen, and X310 checks 4K clips by touch
Quick verdict
Pick a small screenless front camera, or go for 4K recording with a touchscreen and GPS.
Before you buy
Why, and what it costs you
Pick a front-frame size that fits the view you really need
Per front frame, Dash Cam Mini 3 records 2.1 million pixels and Dash Cam X310 records 8.3 million. The larger front frame has 4 times the pixel count, which does not prove a matching increase in useful detail.
Where this comes from
1920 × 1080 = 2073600 pixels, and 3840 × 2160 = 8294400 pixels. This puts output dimensions side by side and leaves out sensor size, shutter speed, compression and readable plate distance.
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
Garmin Dash Cam X310
Despite the premium price, it records the front only.

What this page compares
Before you pick a dash cam, weigh the Dash Cam Mini 3 against the Dash Cam X310 on recorded views, card capacity, parking setup and clip review.

Which one fits
Pick the situations that sound like you
A trip on which the directions recorded count for more than the headline 4K label
Each is a front-only Garmin camera with an integrated polarizer. The Mini 3 keeps the installation small and depends on your phone for review, whereas the X310 brings a 2.4-inch touchscreen and a 4K front stream.

Depends
A long shift that comes with a defined clip-retention requirement
MicroSD cards of up to 512GB work in both. The X310’s higher-resolution mode can use different bitrates, so equal card limits don’t establish equal retained hours. Build your archive plan around the exact recording setting.

A parked car that depends on the correct power and trigger behavior
GPS data is recorded by the X310, but the Mini 3 does not include GPS. A smaller device can be enough for a simple road view. Still, anyone who specifically needs route or speed data should not expect the Mini to pick up that feature through its polarizer or Wi-Fi.

Going with X310 does not give a front-only installation a second direction
In that selected configuration, both Garmin units record one front view and need no separate rear-camera cable. What the X310 upgrade buys is touchscreen, GPS and 4K, and not a second road direction.

Differences you will notice

How we worked this out
1920 × 1080 = 2073600 pixels, and 3840 × 2160 = 8294400 pixels. This puts output dimensions side by side and leaves out sensor size, shutter speed, compression and readable plate distance.
02
Put storage on a common footing without promising how long it records
Dash Cam Mini 3 has a checked 512GB microSD ceiling, and Dash Cam X310 has 512GB microSD. Equal capacity leaves bitrate and channel count to decide retention.
How we worked this out
Capacity is decimal here, with 1TB = 1000GB, and 512 ÷ 512 = 1. It is not a bitrate or runtime measurement.
03
Going with X310 does not give a front-only installation a second direction
In that selected configuration, both Garmin units record one front view and need no separate rear-camera cable. What the X310 upgrade buys is touchscreen, GPS and 4K, and not a second road direction.
How we worked this out
Included view count is 1 versus 1, so the difference = 0. A camera added separately falls outside these single-unit configurations.

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 Garmin Dash Cam X310
A subscription and constant networked power may be needed for Vault storage, remote live view and Parking Guard.

4K front recording and GPS are what you want
Go with Garmin Dash Cam X310. GPS data is recorded by the X310, but the Mini 3 does not include GPS. A smaller device can be enough for a simple road view. Still, anyone who specifically needs route or speed data should not expect the Mini to pick up that feature through its polarizer or Wi-Fi.
Decision guide
How to decide
01
Start with which directions get recorded
Each is a front-only Garmin camera with an integrated polarizer. The Mini 3 keeps the installation small and depends on your phone for review, whereas the X310 brings a 2.4-inch touchscreen and a 4K front stream.
02
Match your local storage to the settings you choose
MicroSD cards of up to 512GB work in both. The X310’s higher-resolution mode can use different bitrates, so equal card limits don’t establish equal retained hours. Build your archive plan around the exact recording setting.
03
Look at the controls and the parked-car install
GPS data is recorded by the X310, but the Mini 3 does not include GPS. A smaller device can be enough for a simple road view. Still, anyone who specifically needs route or speed data should not expect the Mini to pick up that feature through its polarizer or Wi-Fi.
Check these before you buy
On the listing you select, verify the exact camera channels, the inside-window rear mounting and which accessories are included.
Ask the installer to verify power-kit compatibility and to check battery protection, cable routing and airbag clearance.
Once the cameras are fitted, test the real view, the reflections and clip export.
What this page can’t tell you
This page makes no claim of any real-world plate-reading, night-vision or reliability test.
A capacity calculation can’t promise a number of retention days, because bitrate, protected clips, formatting and parking use all change the result.
Parking features depend on the right constant power. Don’t assume a low-power wake-up mode saves footage from before an impact.
