The Hyundai Palisade is one of the most family-friendly three-row SUVs money can buy. It tows, it carries eight people, and it coddles everyone in ventilated leather. But like almost every modern Hyundai, it leaves one thing out of the standard equipment list: a dash camera. When a parking-lot door ding happens, when a light turns red three seconds before the truck behind you decides to stop, or when a deer decides the road is its runway, you have no footage — only your word against theirs.
You could bolt a universal dash cam to the windshield with a suction cup and drape a power cord across the cabin. Millions of people do exactly that, and there's nothing wrong with it — until you actually look at the interior and see a plastic brick hanging off the glass with a cable snaking toward the cigarette lighter. For a vehicle this premium, there's a better answer. A vehicle-specific dash cam replaces the factory rearview mirror housing cover with a camera that looks like it was installed in Ulsan alongside the rest of the car. Its single power cable tucks invisibly into the factory gaps along the headliner and door seal, down to the OBD port — no visible wiring, no suction cup, no trim panel removal. This guide walks you through fitting the Mercylion G444 — a hidden dash camera purpose-built for the 2023 Hyundai Palisade dash cam market — in under half an hour, with nothing more than the included pry tool.
Quick Answer: Yes — plan on about 25 minutes with zero wiring experience. The Mercylion G444 is an OEM Style replacement for the rearview mirror housing. Pop off the plastic cover, snap the camera into the mirror base, tuck the included power cable along the headliner and door weatherstrip, and plug it into the OBD port under the dash. Plug & Play means exactly that: no wire cutting, no fuse taps, no trim panel removal, no permanent modification. Difficulty: 2/5 — if you can change a lightbulb, you can install this.
Here's the honest truth about universal dash cams: the recording quality is often fine, but the installation is where they fall apart. Let's look at the three biggest problems owners run into.
Problem 1: The suction cup becomes a heat grenade. Leave a cheap suction mount on a summer windshield and the adhesive softens, the cup pops, and your $80 camera becomes a missile aimed at your passenger's head. The integrated housing of an OEM Style dash cam clips directly onto the mirror base — there is no mount to fail, because the camera is the mount.
Problem 2: The cable clutter. A universal cam needs 12V power, which usually means running a wire from the dash cam, along the headliner, down the A-pillar, and into the fuse box — or worse, dangling it to the cigarette lighter. That's the "I can see your dash cam wire from three cars away" look. A direct fit camera hides its one power cable in the factory gaps instead: behind the headliner edge, inside the door weatherstrip, all the way down to the OBD port. No splicing anywhere, no wire across the cabin, nothing visible from any seat — a genuine no wiring look without cutting or tapping a single circuit.
Problem 3: It looks aftermarket. If you care about resale value or just about not making a $50,000 SUV look like a rideshare beater, a glass-mounted camera with a cord is a constant eyesore. An integrated unit restores the factory cover, so a passenger — or a parking attendant, or a thief — has to look twice to even notice there's a camera.

The Palisade's rearview mirror housing changed with the 2023 facelift, which is why Mercylion builds separate SKUs for each generation. Do not try to force the wrong-year cover onto your car — the clips and contours are different.

Compatibility checklist before you order:
Trim coverage: SE, SEL, Limited, XRT, and Calligraphy facelift models are all supported as long as the mirror housing matches. Mercylion's pre-order check (send your model, year, and a photo of the mirror area) takes the guesswork out entirely.
The G444 draws power through the included OBD power cable. One end plugs into the camera unit, the other into the OBD-II diagnostic port under the driver-side dash, and everything in between hides completely in the factory gaps along the headliner and door weatherstrip. You never cut a wire, tap a fuse, or expose a terminal — and because the OBD connection keeps the camera powered even with the ignition off, it doubles as your 24-hour parking monitoring source with no extra hardware.
The G444's packaging is straightforward: the camera ships with the cable you need and the tools you don't want to buy. Depending on the bundle you choose, expect:
Standard package (4K Front with 64G):
Front + Rear package (4K Front + 2K Rear with 128G), add:
Total time: about 25 minutes for the front camera; add 10-15 minutes if you're routing the rear camera cable. Tools needed: just the included pry tool and a clean microfiber cloth. Let's go.
Park the Palisade in a shaded spot and let the interior cool — the plastic clips behave better when they're not baking in the sun. Shift the mirror so you can see the housing behind it clearly. You should see the factory plastic cover that wraps around the mirror stem where it meets the windshield. Take a moment to compare the cover against the G444's housing — the clips and contours should mirror each other exactly. If anything looks different, snap a photo and send it to Mercylion before you start.
Pro Tip: Roll the seat all the way back and tilt it down. You'll spend most of this install with your chin near the headliner, and the extra room makes every step easier.
Using the included pry tool, gently work the factory cover loose, starting at the front edge nearest the windshield. The cover is held by a series of plastic clips; apply steady outward pressure and work your way around rather than yanking one corner. Once the front edge releases, slide the cover forward and off the mirror base. Some facelift Palisade housings have a small separate piece over the sensor area — pop that off first if yours does. Set both pieces aside in the box lid; you'll want them safe in case you ever need to revert to stock.
STEP 2: Removing the factory mirror cover with a pry tool
Pro Tip: Push, don't pry. If the cover resists, you're catching a clip — move two centimeters and try again. Scratched trim is the only real "oops" in this install, and it's 100% avoidable with patience.
Take the G444 out of the box and connect the power cable's small plug to the port on the back of the unit — it's keyed, so it only seats one way, and you'll feel it click. Then line up the G444's rear clips with the mirror base and push the unit onto the stem until the rear clips click, followed by pressing upward on the front edge until the front clips engage. The camera should sit flush with the trim, with zero gaps and no movement when you wiggle it. The lens faces the windshield on the passenger side of the housing, just like the factory sensor module.
Pro Tip: Before you push the front clips home, make sure the camera's power cable isn't pinched between the housing and the mirror base. Tuck it into the channel above the clips so it routes cleanly toward the headliner.
Starting at the mirror, run the power cable behind the headliner edge along the top of the windshield on the passenger side — press it into the gap between the headliner and the roof with your fingers or the flat edge of the pry tool; friction holds it in place with no clips. At the corner of the windshield, gently peel the door weatherstrip (the rubber seal running up the A-pillar) away from the frame, lay the cable into the channel behind it, and press the seal back. Keep the cable inside that channel the whole way down: the A-pillar houses the curtain airbag, and the weatherstrip channel keeps the wire clear of it — no trim panel ever comes off. At the bottom, feed the cable behind the dash trim toward the driver's footwell where the OBD port lives.
Pro Tip: Don't pull the weatherstrip off its mounts — just open its lip far enough to drop the cable in. The seal should press back flush by hand. If anything needs force, stop and re-check the channel.
Under the driver-side dash, find the OBD-II port — a trapezoid-shaped 16-pin connector, usually clipped to the trim below the steering column (kneel beside the car and look up under the dash). Plug the cable's OBD connector in; it only fits one way and clicks home. Coil any excess cable loosely and tuck it behind the dash trim so nothing dangles in the footwell. Because the OBD connection stays powered with the ignition off, this single plug is also what keeps the camera armed for 24-hour parking monitoring.
Pro Tip: The OBD port is designed for diagnostic scan tools, but the G444's draw is tiny (about 250mA) and the connector is keyed — you can't plug it in wrong. If your mechanic ever needs the port, the connector pulls straight out in two seconds.
If you bought the front + rear bundle, run the 5.5m extension cable from the G444 along the headliner: tuck it behind the front headliner edge, run it over the driver or passenger side (the side you'll mount the rear camera on), across the B-pillar area, and down to the top of the rear windshield. Use the included pry tool to tuck the cable into the headliner gap — it stays in place with friction, no clips required. Mount the rear camera on the rear glass with the electrostatic film (no adhesive residue), positioning it to see the rear window. Plug the camera into the extension cable and verify the rear channel appears in the app.
Pro Tip: Route on the passenger side so you never have to tuck cable while sitting in the driver's seat — the extra three minutes of walking around the car beats contorting yourself under the steering wheel.
Reinstall any small cover pieces you removed, and double-check that the power cable sits fully hidden along the headliner and weatherstrip. Start the Palisade — the G444 powers on automatically and begins recording (watch for the blue status light). Open the Mercylion app, connect to the camera's WiFi network (it appears as a "Mercylion..." SSID; default password 12345678), and check that the live view is level and centered. Format the MicroSD card through the app once before daily use to initialize the file system. Give the car a light tap to confirm the G-sensor saves an emergency clip to the locked folder.
Pro Tip: Download one clip to your phone during setup and check the date/time stamp. If the clock is off, the G-sensor timestamps will be too — a wrong time can hurt your evidence in an insurance dispute. Set the correct timezone in the app on day one.
The G444 records true 4K Ultra HD at 3840×2160P/30fps using a Novatek NT96565 processor and an 8-megapixel CMOS sensor with a bright F1.5 aperture. That aperture matters: the wider the lens opens, the more light reaches the sensor at night, which is exactly when dash cam footage usually turns to noise. The 2G4P+IR glass lens and WDR (wide dynamic range) processing balance bright headlights against dark plates so you can actually read what matters in the frame. At 145° diagonal field of view, you capture the full three-lane picture without the fisheye distortion cheap cams add to stretch their angle claims.
A dash cam that can't see the car pulling out of the corner lot is a dash cam that missed the accident. The 145° lens covers the entire front of the Palisade plus both adjacent lanes, while the F1.5 aperture and IR-coated optics keep low-light footage usable instead of a smear of pixels. This is the difference between "I have a camera" and "I have footage that an adjuster can use."
The G444 broadcasts its own WiFi network (802.11b/g/n/ac), so you don't need mobile data to review anything. Open the Mercylion app, connect, and you get live view, playback, downloads, and settings — including resolution, loop length (1/3/5 minutes), and G-sensor sensitivity. Footage downloads to your phone's album for instant sharing with your insurance company or the police. Critically, the camera keeps recording while you're in the app, and it doesn't interfere with Apple CarPlay or Bluetooth — it's a separate network, not a hijack of your phone.
Here's the feature that saves your bacon in the grocery store lot. Because the G444 draws its power from the OBD-II port, parking monitoring needs no extra hardware and no fuse-box work: the camera stays armed while the Palisade is parked. When the triaxial accelerometer detects a collision or impact — a door ding, a bumper tap, a hit-and-run — recording starts within seconds and saves the clip to a protected folder. No battery anxiety: the camera's low-power draw (about 250mA at 12V DC) and the vehicle's own battery management keep daily driving unaffected. Heading to the airport for a week? Pull the OBD connector before you leave and the camera powers down completely.
The built-in triaxial accelerometer detects sudden deceleration or impact and instantly locks the relevant footage into an emergency folder that loop recording will never overwrite. Routine driving footage loops continuously (1/3/5-minute segments), overwriting the oldest clips when the 64GB (or up to 256GB) card fills. The result: you always have the last several hours of driving available, and you never lose the moment that actually mattered.
Need more than video? The G444 supports an external GPS module (sold separately) that overlays speed, coordinates, and route data onto your footage. That's valuable if you ever need to prove where you were and how fast you were going — the app displays longitude, latitude, and speed during playback. It's a cheap add-on that turns a witness camera into a full evidence recorder.
The G444 draws roughly 250mA at 12V — about 3W. In collision-triggered parking mode it isn't recording continuously, so the load is minimal. Hyundai's battery management plus the low draw means a normal daily driver won't see a noticeable drop. For multi-day airport parking, simply unplug the OBD connector before you leave — parking mode pauses and the battery stays untouched.
Power comes from the OBD-II port rather than the mirror, so a non-auto-dimming mirror isn't a power problem — the G444 never touches the mirror's wiring. What matters is that the replacement housing matches your mirror's design. Send a photo of the mirror area to info@mercylion.com before ordering and Mercylion will confirm the right SKU for your trim.
No — and that's a feature, not a bug. The housing is vehicle specific, molded to the 2023-2025 Palisade's mirror base with 1:1 geometry. A universal cam transfers, but it also never fits anything perfectly. The G444's factory-matched cover is precisely why it looks invisible in the car. If you sell the Palisade, the camera is easy to unplug and resell to another facelift owner.
Yes, the G444 has a built-in 8Ω 1W speaker and a microphone, and audio recording can be toggled on/off in the app. If your state has two-party consent laws for recording, turn audio off and keep video only.
G443 fits the pre-facelift Palisade (2020-2022); G444 fits the facelift (2023-2025). The housing geometry changed with the 2023 refresh, so the covers aren't interchangeable. Choose by model year, and use Mercylion's pre-order check if you're unsure.
Mercylion's compatibility check before shipping (they ask for your model, year, and mirror-area photo) makes a wrong-fit near impossible. If anything doesn't click in cleanly, don't force it — contact Mercylion support; they'll sort out the correct SKU, and the 30-day return window covers you.
The 2023-2025 Hyundai Palisade is a flagship SUV that deserves a dash cam that doesn't look like an afterthought. The Mercylion G444 delivers exactly that: a hidden dash camera with a custom fit housing, true plug and play OBD power, 4K evidence-grade footage, and a 25-minute install that any owner can finish in a driveway. No suction cups, no dangling cables, no trim panel surgery — just a factory-finished camera that's recording the moment you start the engine. For families who park in crowded lots, commute on busy highways, or simply want to protect a significant investment, it's the right upgrade at the right price.
