Garmin Dash Cam Mini 3: The Tiny One, Compared for Australia
The short verdict. The Garmin Dash Cam Mini 3 is the smallest dash cam most Australians will seriously consider, and that is its real argument. It records 1080p, which is entry level in 2026, and Garmin does not list GPS in its specification. If a camera nobody notices is genuinely what you are after, it earns its place. If you are buying a dash cam to prove what happened, the missing speed stamp matters more than the resolution does.
Key takeaways
- The Garmin Mini 3 is genuinely tiny, and nothing we sell matches it on size.
- It tops out at 1080p and Garmin does not list GPS, and of those two, the missing GPS is the one that costs you on the day it matters.
- Size is the reason to buy it. Evidence quality is the reason to look at something else. Which of those you care about decides it, not the ticket.
You have probably found the little Garmin the same way most people do. Someone mentioned it, you looked it up, and the thing is about the size of a car key. No screen, nothing to catch your eye on the windscreen. Then you started reading the specification and the 1080p line gave you pause, because everything else in that part of the market seems to be 2K or better.
Cards on the table first. We stock VIOFO, Vantrue and WOLFBOX. We do not sell Garmin and we have no commercial relationship with Garmin. We have never had a Mini 3 on our bench, so everything below about the Garmin comes from Garmin's own published material, and we have said so where it matters. We are not neutral. We have tried to be accurate instead. Where the Garmin is the stronger choice, we have said so, and there is a section below where we say exactly that.
What is the Garmin Dash Cam Mini 3?
It is Garmin's smallest camera, and the whole design follows from removing the screen. Garmin describes the Mini 3 as car-key sized. Take away the display and you take away the reason a dash cam has to be big, so setup and playback happen on your phone in the Garmin Drive app instead.
Here is what Garmin publishes about it. Recording is 1080p at 30 frames per second, through a 140 degree lens. There is a built-in Clarity Polarizer, which Garmin describes as reducing windscreen reflections. Voice control is included, and Garmin lists it as working in English, German, French, Spanish, Italian and Swedish. There is Wi-Fi for the app, automatic incident detection, and microSDXC card support up to 512GB.
What Garmin does not list is GPS. That matters more than it sounds, and we come back to it below.
What should you expect to pay?
We do not publish prices in our articles, and the Mini 3 is a good illustration of why. Its price has moved a long way from Garmin's own recommended figure, it moves differently at different retailers, and a promotion can end the week after we write about it. A number we typed in August is not a number you can act on in November.
So check it yourself on the day, on Garmin's own Australian store and at the big electronics and auto retailers, and compare that against the front-only cameras we stock at whatever they are on the day too.
What does not move is the specification, and that is the part worth reading a comparison for. The Mini 3 is the same camera whatever it costs this week. The rest of this article is about what that camera can and cannot do for you.
The two cameras we would put against it
Both are front-only, both are small enough to hide behind the mirror, and both use a Sony STARVIS 2 sensor. That sensor family is the part of the camera that turns light into a picture, and it is the single biggest reason a number plate stays readable under a streetlight rather than smearing into a grey blur. We explain what it changes in our STARVIS 2 explainer.
The VIOFO VS1 Mini is the closer match on philosophy: screenless, discreet, 2K, and it ships with a 32GB card so you can fit it the day it arrives.
The VIOFO A119 Mini 2 is the one we would actually fit, because it will run 1440p at 60 frames per second. Think of video as a flip book. Twice as many pages a second means less blur on any single page, so a car crossing in front of you gives you twice as many chances at a readable plate.

Methodology note: we have not run a Garmin Mini 3 and a VIOFO on the same windscreen on the same night. Every Garmin figure above comes from Garmin's own published material, checked 6 August 2026, and every VIOFO figure comes from our own product listings. Nothing here is a Dash Cam Guys test result.
How much does 1080p versus 2K really matter?
More than the marketing suggests, and less than the spec-sheet arguments online would have you believe.
Resolution is how many dots make up the picture. 1080p is about two million of them, 1440p is about 3.7 million. When the thing you need is a number plate on a car two lanes over, or a plate on a car pulling away from you, those extra dots are the difference between six characters you can read out and a grey rectangle you cannot.
Where it matters less is the everyday case. If someone reverses into you in a car park at walking pace and stays put, 1080p tells that story perfectly well. Most incidents are like that.
So the honest framing is not "1080p is useless". It is that 1080p gives you fewer options on the day the incident turns out to be the awkward kind, and the awkward kind is exactly the day you bought a dash cam for.
The GPS question, which matters more than the resolution
Garmin does not list GPS in the Mini 3's specification. Both VIOFO minis have it built in.
GPS on a dash cam stamps your speed, your route and the time onto the recording. That sounds like a nice-to-have until you are the one saying "I was doing sixty" and the other driver is saying you were doing ninety. Without it your footage shows what happened but not how fast you were going, and speed is the single most argued point after a collision.
If your reason for buying a dash cam is protecting yourself in a dispute, this is the specification we would not compromise on. It is a bigger gap than the 1080p line, and unlike resolution there is no partial version of it. You either have the speed stamp or you do not.
Parking mode, and the subscription worth knowing about
Parking mode means the camera keeps watching after you switch off, so a trolley strike or a hit-and-run in your street gets recorded. Every camera here needs extra hardware for it, because the cigarette lighter socket in most cars goes dead with the key.
The fix is a hardwire kit, a thin loom that taps a permanently live fuse in your fuse box and feeds the camera directly. The safety net is the low voltage cut-off: you set a threshold, and when your battery drops to it the kit shuts the camera down so you still have enough charge to start the car.
The Garmin has one extra wrinkle. Garmin states that its parking alert feature, which pushes a notification to your phone, needs a paid Vault subscription as well as constant power and a live Wi-Fi or hotspot connection. The camera still records while parked without it. You just do not get told. That is worth factoring in if the phone alert was the part you wanted, and it is worth checking Garmin's current terms yourself, because subscription features change.
Pro Tip: whichever you buy, test the cut-off over a weekend before you rely on it. Park the car Friday night, leave it alone, and start it Monday morning. If it fires up without hesitation your threshold is right. If it labours, raise the cut-off voltage a step. Far better to learn that in your own driveway than in an airport car park after a week away.
Where the Garmin Mini 3 genuinely wins
Size, and we are not going to talk around it.
Garmin describes the Mini 3 as car-key sized. The VIOFO VS1 Mini and A119 Mini 2 are both small and both hide behind a mirror in most cars, but neither is that small. If your windscreen has a big sensor housing around the mirror eating the space, or if you simply do not want a passenger to notice there is a camera, the Garmin has the edge and no amount of resolution changes that.
There is a second win worth crediting, and it surprised us. Garmin publishes the Mini 3's battery type as "No (uses supercapacitor)". A supercapacitor holds just enough energy to finish writing the current file and shut down cleanly, and it copes with repeated heat cycling far better than a rechargeable lithium battery does. That matters in a car parked in the open through an Australian summer. Our supercapacitor explainer covers why. Worth knowing that Garmin publishes a rechargeable lithium-ion battery for its larger X110, X210 and X310, so on this one point the little Mini 3 is the better-suited camera of the Garmin range for our climate.
There is a third, quieter win. If you already run a Garmin watch or sat nav, the Mini 3 lives in an app you have already got. Not a specification, but convenience is worth something real to some people and we are not going to pretend otherwise.
Buy if, skip if
Buy the Garmin Mini 3 if the camera being close to invisible is the thing that decides it for you, your windscreen has little room around the mirror, or you are already in the Garmin app every day. Go in knowing you are accepting 1080p and no speed stamp, and that both of those are deliberate trades for the size.
Skip it if your main worry is proving fault in a dispute. The missing GPS is the real gap there, and the VIOFO A119 Mini 2 records 2K at 60 frames per second and logs your speed in a body that still hides behind the mirror. Skip it too if you want the option of reading a plate two lanes over, because that is where the extra resolution earns its keep.
What we could not verify
- The Mini 3's physical dimensions and weight. Garmin's Australian page describes it as car-key sized but publishes no measurements.
- Which image sensor Garmin uses. Garmin does not disclose it, so we cannot compare it like for like against STARVIS 2.
- Garmin Vault subscription pricing in Australia.
- Garmin's voluntary warranty period for the Mini 3 in Australia. Check Garmin's own published terms, and note that your rights under Australian Consumer Law apply on top of any voluntary warranty regardless.
- Whether a microSD card or a parking mode cable is in the Australian retail box.

Commercial disclosure
Obvious, but worth saying: we have a horse in this race. We sell VIOFO, Vantrue and WOLFBOX. We do not sell Garmin and we have no commercial relationship with Garmin.
So do not just take our word for it. Read what others have found, then make your own call. This is buying advice from a retailer, not a lab test.
Between us we have more than 15 years in dash cams, and we would rather lose a sale than fudge a number. We have never had a Mini 3 on our bench. Every Garmin specification above is published by Garmin and was checked on 6 August 2026. Anything we could not source came out, and it is listed above under what we could not verify. We are not neutral. We have tried to be accurate instead.
No brand paid for, sponsored or supplied anything for this article. We buy the cameras we review out of our own stock, the same stock we sell; we have not bought or tested the Garmin Mini 3. Where the Garmin is the stronger choice, we have said so.
