Head-to-head
VIOFO A329S 2CH vs Garmin Dash Cam X310: A329S records the rear road, X310 avoids that cable and mount
The short answer
The first decision is whether you need rear-road footage. A329S 2CH includes a 2K rear camera for the standard inside-window installation, alongside its 4K front camera. X310 is front-only, avoiding the rear cable and mount while adding a 2.4-inch touchscreen and integrated polarizer. Choose the recorded directions and controls you need before considering extra storage.
Before you choose
The reasoning and the trade-offs
Match front-frame size to the view you actually need
A329S 2CH and Dash Cam X310 have the same 8.3-million-pixel front frame. Their included channel counts are 2 and 1, so coverage and the selected modes deserve more attention than the equal front label.
What this is based on
3840 × 2160 = 8294400 pixels. 3840 × 2160 = 8294400 pixels. This compares output dimensions, not sensor size, shutter speed, compression or readable plate distance.
Main trade-off
Garmin Dash Cam X310
It is a front-only camera despite its premium price.

- Choose it for
- You need a rear-road camera
- You want to retain footage on an external SSD. An A329S SSD driving archive needs a separately purchased compatible drive and VIOFO cable, suitable GPS-mount power, SSD selected and Privacy Mode off. One target records, and explicit card-to-SSD copying is separate, not simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.

Winner by situation
Start with what you need it to do
A trip where the recorded directions matter more than the headline 4K label
A329S provides 4K front plus 2K rear. X310 is front-only and offers 4K recording in a touchscreen device. Decide whether the rear evidence is worth the additional cable and rear-window mount.

A long shift with a defined clip-retention requirement
A329S has a 4TB SSD option while both support up to 512GB microSD. The external drive must be powered and secured appropriately, and low-power VIOFO impact clips still use the card. An A329S SSD driving archive needs a separately purchased compatible drive and VIOFO cable, suitable GPS-mount power, SSD selected and Privacy Mode off. One target records, and explicit card-to-SSD copying is separate, not simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.

A parked car that needs the correct power and trigger behavior
A329S’s 4K60 setting requires HDR off. Garmin offers its own lower-resolution high-frame-rate choices, so compare the exact desired resolution and mode instead of assuming that any high fps label means the same output.

The A329S 4K60 option records twice as many front frames per second as 4K30
At the chosen 4K setting, A329S can supply 60 front frames per second with HDR disabled, while X310’s 4K mode is 30fps. Garmin’s faster lower-resolution modes are a separate choice.

What matters in practice
The differences that matter
Match front-frame size to the view you actually need
A329S 2CH and Dash Cam X310 have the same 8.3-million-pixel front frame. Their included channel counts are 2 and 1, so coverage and the selected modes deserve more attention than the equal front label.
How we reached this conclusion
3840 × 2160 = 8294400 pixels. 3840 × 2160 = 8294400 pixels. This compares output dimensions, not sensor size, shutter speed, compression or readable plate distance.
Normalize storage without promising a recording duration
A329S 2CH has a checked 4000GB external SSD ceiling versus 512GB microSD for Dash Cam X310. The larger nominal option is 7.8 times the smaller, before formatting and protected-file use. An A329S SSD driving archive needs a separately purchased compatible drive and VIOFO cable, suitable GPS-mount power, SSD selected and Privacy Mode off. One target records, and explicit card-to-SSD copying is separate, not simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.
How we reached this conclusion
Use decimal capacity, with 1TB = 1000GB. 4000 ÷ 512 = 7.8. Capacity is not a bitrate or runtime measurement. A329S Hybrid and Low Power Impact stay microSD-only.
The A329S 4K60 option records twice as many front frames per second as 4K30
At the chosen 4K setting, A329S can supply 60 front frames per second with HDR disabled, while X310’s 4K mode is 30fps. Garmin’s faster lower-resolution modes are a separate choice.
How we reached this conclusion
60 ÷ 30 = 2. This compares the stated 4K modes, not shutter speed or every supported recording resolution.

What you give up
Every choice has a cost
If you choose VIOFO A329S 2CH
- A329S Hybrid and Low Power Impact need a separate compatible high-endurance microSD and compatible GPS-mount hardwire power. Set Hybrid time or voltage, and voltage control needs HK6.
If you choose Garmin Dash Cam X310
- Vault storage, remote live view and Parking Guard may require a subscription and constant networked power.
Recommendation switch
The decision flips if...
You need a rear-road camera
Choose VIOFO A329S 2CH. A329S provides 4K front plus 2K rear. X310 is front-only and offers 4K recording in a touchscreen device. Decide whether the rear evidence is worth the additional cable and rear-window mount.
You want to avoid rear-cable routing
Choose Garmin Dash Cam X310. A329S’s 4K60 setting requires HDR off. Garmin offers its own lower-resolution high-frame-rate choices, so compare the exact desired resolution and mode instead of assuming that any high fps label means the same output.
What matters in practice
How to make the call
Choose the recorded directions first
A329S provides 4K front plus 2K rear. X310 is front-only and offers 4K recording in a touchscreen device. Decide whether the rear evidence is worth the additional cable and rear-window mount.
Plan local storage around the selected settings
A329S has a 4TB SSD option while both support up to 512GB microSD. The external drive must be powered and secured appropriately, and low-power VIOFO impact clips still use the card. An A329S SSD driving archive needs a separately purchased compatible drive and VIOFO cable, suitable GPS-mount power, SSD selected and Privacy Mode off. One target records, and explicit card-to-SSD copying is separate, not simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.
Check controls and the parked-car installation
A329S’s 4K60 setting requires HDR off. Garmin offers its own lower-resolution high-frame-rate choices, so compare the exact desired resolution and mode instead of assuming that any high fps label means the same output.
What this comparison cannot tell you
- No real-world plate-reading, night-vision or reliability test is claimed.
- Capacity calculations do not promise retention days. Bitrate, protected clips, formatting and parking use change the result.
- Parking features require appropriate constant power. Low-power wake-up modes should not be assumed to preserve footage from before an impact.
