Head-to-head
Choose a small screenless front camera or 4K recording with touchscreen and GPS.
Before you choose
Dash Cam Mini 3 records 2.1 million pixels per front frame and Dash Cam X310 records 8.3 million. The larger front frame has 4 times the pixel count, without proving a matching increase in useful detail.
What this is based on
1920 × 1080 = 2073600 pixels. 3840 × 2160 = 8294400 pixels. This compares output dimensions, not sensor size, shutter speed, compression or readable plate distance.
Main trade-off
Screenless settings and local phone playback use compatible Garmin Drive, and playback stops recording and alerts. Ordinary local recording and playback need no Vault plan. Recording needs no constant phone connection after setup. There is no built-in GPS or LTE. Location data needs a separately purchased GPS-enabled camera in the Garmin multi-camera network. A compatible card and parking-power accessory are separate.
Main trade-off
It is a front-only camera despite its premium price.
Compare Dash Cam Mini 3 and Dash Cam X310 by recorded views, card capacity, parking setup and clip review before choosing a dash cam.

Winner by situation
Both are front-only Garmin cameras with an integrated polarizer. Mini 3 keeps the installation small and relies on the phone for review, while X310 adds a 2.4-inch touchscreen and a 4K front stream.
Both support microSD cards up to 512GB. The higher-resolution X310 mode can use different bitrates, so equal card limits do not establish equal retained hours. Plan the archive around the exact recording setting.
X310 records GPS data, while Mini 3 does not include GPS. A smaller device may be enough for a simple road view, but a buyer who specifically needs route or speed data should not expect the Mini to gain that feature through its polarizer or Wi-Fi.
Both Garmin units record one front view and need no separate rear-camera cable for that selected configuration. X310’s upgrade buys touchscreen, GPS and 4K, rather than a second road direction.
What matters in practice
Dash Cam Mini 3 records 2.1 million pixels per front frame and Dash Cam X310 records 8.3 million. The larger front frame has 4 times the pixel count, without proving a matching increase in useful detail.
1920 × 1080 = 2073600 pixels. 3840 × 2160 = 8294400 pixels. This compares output dimensions, not sensor size, shutter speed, compression or readable plate distance.
Dash Cam Mini 3 has a checked 512GB microSD ceiling versus 512GB microSD for Dash Cam X310. The equal capacity makes bitrate and channel count decisive for retention.
Use decimal capacity, with 1TB = 1000GB. 512 ÷ 512 = 1. Capacity is not a bitrate or runtime measurement.
Both Garmin units record one front view and need no separate rear-camera cable for that selected configuration. X310’s upgrade buys touchscreen, GPS and 4K, rather than a second road direction.
Included view count is 1 versus 1. Difference = 0. A separately added camera is outside these single-unit configurations.
Garmin, Mini 3
Garmin Mini 3 is a screenless 1080p front camera with a built-in polarizer and no built-in GPS or LTE. Garmin Drive configures settings. Local recording and playback need no Vault plan. Remote access needs paid Vault in a supported country, compatible app, continuing power and internet Wi-Fi. Card and parking power are separate.
Garmin, X310
The X310 adds native 4K and a responsive 2.4-inch touchscreen to Garmin’s compact, voice-controlled camera format.
