Yes. Please insert the microSD card first. When your car powers the dash cam, it will turn on and start recording automatically. If it doesn’t, please check the power connection and SD card status.

Please adjust the cabin lens so it can see the driver/passenger area clearly without pointing directly at bright reflective surfaces. If you use rideshare, please aim to capture both front seats and the main cabin area.

Please mount it high on the windshield (near/behind the rearview mirror). This helps reduce glare, keeps your view clear, and gives the camera a centered road view.

Yes. Please rotate the rear camera (up to 360°) and adjust the cabin view (up to 270°) to match your vehicle layout and desired coverage.

No. A 64GB microSD card is included and pre-installed.

Yes, please format the microSD card in the app settings before your first use. If the dash cam shows a message asking you to format the card, please press the Function button once to start formatting.

Please look for the recording indicator (LED icon/light) and the recording status on the mini screen. If you connect the app, you can also see the recording status there.

Clean the glass with alcohol, let it dry fully, and apply in a warm environment. Press firmly for 30–60 seconds. Avoid installing on dusty/curved areas.

Please use a stable 5V / 2.5A power supply (Type-C). Low or unstable power can cause reboots or recording issues.

Yes. You can use a USB power option if your vehicle doesn’t have a cigarette lighter socket.

If you’re using the cigarette lighter power cable or a USB power cable, this is normal. When your car stops supplying power, the dash cam will save the current file and then shut down automatically after a short time.
If you want the dash cam to keep recording after the engine is off, you’ll need the GKU hardwire kit connected to your vehicle’s fuse box.

With the regular car charger, no (it turns off with the car). For 24/7 parking monitoring, you need a hardwire kit and proper installation to protect the battery.

You can power the dash cam with a compatible USB power cable. If you don’t have a USB cable, or your cable can’t provide enough power, please contact the GKU support team—we can provide a USB power cable for you.

Yes, it can. Please use the original car charger whenever possible. Unstable power may cause recording issues or unexpected restarts.

Yes, but please note: you will need a hardwire kit connected to the fuse box. Plug-in power usually turns off with the car.

It supports 3-channel recording: Front 4K + Inside 1080P + Rear 1080P. It also supports alternative modes like Front 2.5K + Inside 1080P + Rear 1080P, plus dual/single modes.

Please press OK to switch the screen view while recording (front/inside/rear and multi-view).

Please do the following while the dash cam is recording:

Please press the yellow Emergency Lock Button once.

After you press it, the dash cam will start recording an Emergency (Locked) video.

Please look at the screen—the red recording icon will turn yellow, and you will hear a voice prompt confirming the video is locked.

Please note: Locked videos are saved in the “Locked” folder and will not be overwritten by normal loop recording. To free up space, please remember to back up important clips first, then delete locked files manually when needed.

Yes. Please press the Function button once to lock a video. After you press it, the dash cam will start recording an emergency (locked) video. You’ll see a lock icon on the screen and hear a voice prompt confirming the video is locked.
Locked videos are saved in the Locked folder and won’t be overwritten by normal loop recording, so please remember to delete locked files manually after you back up anything important.Please note: Only the video recorded after you press the button will be locked. The footage recorded before you press the button is normal loop recording and can be overwritten.

It records in short clips (1/3/5 minutes). When the card is full, it overwrites the oldest unlocked clips so it can keep recording.

That’s how loop recording works. Short clips are easier to save, search, and protect during incidents.

Yes. You can turn audio recording on/off in settings.

No. Please note: locked videos are protected and won’t be overwritten by normal loop recording.

Yes. The cabin camera has 4 IR LEDs and will switch to IR night vision automatically in low light, so it can capture cabin footage even in darkness.

Please don’t worry—IR night vision is typically black-and-white. That’s normal and helps improve clarity in very dark environments.

32GB–512GB.

Please use a Class 10 U3 (or faster) microSD card from a reliable brand (Samsung/SanDisk are common good options).

Yes. New cards should be formatted in the GKU GO app.

Format the card to FAT32 on a computer first, then format it again in the app.

Usually the card is missing, unrecognized, or faulty. Format or replace the microSD card.

No. Locked videos won’t be overwritten by normal loop recording. Locked clips are saved in the Locked folder, and they will not be replaced by the loop function. If you need to free up space, you’ll need to delete locked files manually (after backing up any important clips).

If you use the camera daily, backing up important files and formatting periodically can help keep recording stable.

Please check the app’s Camera Files first. If needed, please remove the microSD card and use a card reader to view files on a computer. If there are still no videos, the card may be faulty—please format the card or try a better card (Class 10 U3 or faster).

Yes. Please back up important videos before formatting.

Use the GKU GO app on iOS/Android.

First, make sure the dash cam is powered on and Wi-Fi is turned on. You can tap the Wi-Fi icon on the dash cam screen to turn Wi-Fi on/off.
Then open the GKU GO app → tap Add Dash Cam. On your phone, go to Wi-Fi settings → connect to GKU-D700-XXXXX → enter password 12345678.

This is normal. The dash cam’s Wi-Fi is only for live view, downloading videos, and changing settings—it does not provide internet access.
When you disconnect from the dash cam Wi-Fi, your phone will go back to using cellular data or your home Wi-Fi normally.

No. It records normally without Wi-Fi. Use Wi-Fi only when you want to view/download footage or change settings.

Stay within 3–5 meters, and try turning off Bluetooth + cellular data while connecting.

The default password is 12345678.

Open GKU GO → Camera Files → select a clip → download. Keep your phone close for faster transfer.

Yes, when GPS is active it can record speed/location/route for playback.

GPS needs an open area to receive satellites. Indoors/garages may block the signal.

Use the app, or use the GKU Player on a computer for GPS track playback.

Enable Speed Watermark and GPS Coordinates in settings, and give it time to get a GPS lock in an open area.

GPS speed can differ slightly from your car’s speedometer. That’s normal.

Yes—but it requires a separate hardwire kit (not included).

Impact detection (G-sensor trigger) and Time-lapse. Both require the hardwire kit.

After you turn off the engine, the dash cam will power down automatically (this feature requires the hardwire kit ).
If the camera detects an impact while parked, it will turn on automatically, start recording, and save the clip as a locked video.

Time-lapse recording will start only after you turn off the engine (parking mode requires the hardwire kit ).
It records at a lower frame rate to save power and storage, so you can keep monitoring your car while it’s parked for longer.

Install a compatible hardwire kit first, then enable parking features in settings.

They are saved on the microSD card like other recordings.

Time-lapse parking videos are saved in the Loop (normal) folder.

Impact/event videos (triggered by collision detection) are saved in the Locked folder.

Please don’t worry—our parking mode is designed to help reduce battery drain.

After you turn off the engine, time-lapse parking recording uses a low frame rate, which helps save power.

Our hardwire kit includes a low-voltage protection feature. If your vehicle battery voltage drops too low, the kit will automatically cut off power and shut down the dash cam to help prevent the battery from being drained.

Please don’t worry—this hardwire kit is designed specifically for vehicle use.

Input voltage: It supports 12V–24V vehicle electrical systems, which works with most cars, SUVs, and trucks.

Output voltage: It converts vehicle power to a stable 5V output, which is the voltage the dash cam needs.

Fuse amp rating: The dash cam’s power draw is very small, so a 2A or 3A fuse is enough for normal use.

Step 1: Locate your vehicle’s fuse box
Please find your fuse box using your vehicle’s Fuse Box Diagram (owner’s manual or fuse box cover diagram).
Please open the fuse box cover. Some covers lift by a small tab; others may require gently prying a panel—please use the included trim tool if needed.
 If you have trouble locating the fuse box, please let us know and we’ll help.

Step 2: Identify the correct fuse slots (ACC + Constant Power)
You will need two fuse slots:
 Constant Power fuse (Yellow wire): provides power all the time, even when the engine is off. (Required for parking mode.)
 ACC fuse (Red wire): provides power only when the key is in ACC/ON. (Used for normal driving recording.)

Step 3: Connect the Red & Yellow fuse taps (Add-A-Fuse) and verify with a voltmeter

Please use a voltmeter to confirm you picked the correct fuse slots:

Red Wire (ACC): Please turn the car key to the ACC position.Please test the aluminum end of the RED Add-A-Fuse with a voltmeter.If you see voltage, it confirms this slot is powered in ACC.

Yellow Wire (Constant/B+): Please turn the car off. Please test the aluminum end of the YELLOW Add-A-Fuse with a voltmeter. If you still see voltage, it confirms this slot is constant (always-on) power.

Step 4: Locate a good ground point (Black wire)

Please connect the Black wire (Ground) to a solid metal screw/bolt on the vehicle chassis. We strongly recommend using a proper ground point for stable power.

Please note: an improper ground connection may cause the dash cam to malfunction or restart intermittently.

After wiring, please power on the dash cam and confirm it records normally.Please check that Parking Mode appears in the app/settings after a correct hardwire installation. If your fuse type doesn’t match the fuse taps you have, please contact us

No. It’s recommended to install it inside the vehicle.

Yes. The rear view can be flipped in settings for flexible installation.

The rear camera cable is 19.69 ft long. If the cable isn’t long enough for your vehicle, we also offer a rear camera extension cable. Please contact the GKU support team, and they can send you one.

Please re-seat the rear camera cable on both ends and restart the dash cam. If it still shows no signal, please contact GKU support.

Yes. Use a card reader to view files, and use the GKU Player for GPS track playback.

Try playing the video with the GKU Player or another video player. Some built-in/default players don’t work well with dash cam video formats, which can cause playback issues.

No. The camera Wi-Fi is short-range local Wi-Fi. It does not support cloud/remote viewing.

-4°F to 158°F (-20°C to 70°C).

Yes, it supports dual-band Wi-Fi (2.4GHz/5.8GHz).

Yes. It’s designed for standard 12V vehicles (car/minivan/SUV/truck).

The standard warranty is 1 year, and we also provide lifetime technical support. If you register your product, you can extend the warranty by 1 additional year (for a total of 2 years).

Make sure your car power is on and the charger is plugged in securely. Then try powering the dash cam using the included cigarette lighter power cable or a USB power cable to check whether the issue is related to the power source or cable.

Please don’t worry—this is usually not a dash cam problem. If you’re using the included cigarette lighter power cable (or a USB power cable) and the camera is still recording a few minutes after you turn off the engine, it usually means your vehicle’s power outlet is constant power (always-on).
In other words, the dash cam is still receiving power, so it will keep recording.

Please try one of the following options:

Please use a different power outlet in your vehicle.
Some cars have one outlet that stays on all the time and another outlet that turns off with the engine. If you switch to an ignition-switched outlet, the dash cam will shut off automatically after the car powers down.

Please use another power method.
If your outlet is always-on, you may want to use a different power setup that turns off with the vehicle.

Please unplug the power cable after you turn off the engine.
This is the simplest way to make sure the dash cam stops recording and helps prevent battery drain.

Confirm Wi-Fi is connected, close/reopen the app, and close other apps in the background.

Try these steps in order:

Use the original car charger cable that came in the box. Non-original power accessories may provide unstable power, which can cause system issues.

Test a different power method: use a USB-A to USB-C cable (standard USB-A on one end, USB-C on the other) to power the camera for testing.

Avoid USB-C to USB-C (C-C) cables for testing. Many C-C cables won’t power the device unless they support PD (Power Delivery). A USB-A to USB-C cable is the most reliable way to test stable power.

Remove the microSD card, then try powering on again.
If the camera is stable without the card, the issue may be related to the memory card.If the issue still continues, please contact the GKU support team for help.

Yes. Unstable power is a common cause. Please use the original cigarette lighter power cable first. If you want to test USB power, use a USB-A to USB-C cable (avoid C-C cables unless they support PD).

Gaps can happen with a slow or failing memory card, or if power briefly drops. Use the original power cable and a higher-quality microSD card.

Please try the steps below:

Please open the app and check Camera Files to see if your clips are listed there.

If you still can’t find the videos, please remove the microSD card and use a card reader to check the files on a computer.

If there are still no videos, please note the microSD card may not be saving properly. Please try formatting the card in the app, then record again and re-check.

For best results, please use a Class 10 U3 (or faster) microSD card. Samsung or SanDisk are great choices.

Please try these steps:

Please make sure the microSD card is fully inserted into the dash cam (push it in until it clicks).

Please use a name-brand microSD card with Class 10 U3 or faster performance. We recommend 64GB or 128GB cards. Samsung or SanDisk are great choices.

Please open the GKU GO app → go to Settings → find Format microSD Card and try formatting.

If you can’t tap “Format” or you see an error, please remove the card and use a card reader to format it on a computer first (FAT32). Then insert it back into the dash cam and please format it once more in the app.

If formatting still fails, please try a different/new microSD card.

Please try the steps below :

Please reset the dash cam.
Please press and hold the Function button for about 5 seconds until you hear a beep or the device restarts. This means the dash cam has been reset.

If you connected before, please also go to your phone Wi-Fi settings and Forget the dash cam Wi-Fi network first.

Please reinstall the app.
Please delete the GKU GO app and install it again. Please also make sure your phone system settings and app permissions are allowed.

Please reconnect to the dash cam Wi-Fi .
Before connecting, please turn OFF your VPN, cellular data, and Bluetooth. Please keep Wi-Fi only.

Please make sure the dash cam is powered on.

On your phone, go to Wi-Fi → find the network name like GKU_XXXX_XXXXX → tap Connect.

Please enter the default password: 12345678.

Please try the steps below:

Please make sure Wi-Fi is turned ON in the dash cam settings.
Please use the buttons on the dash cam to enter the Settings menu, and confirm that Wi-Fi is enabled.

Please switch the Wi-Fi band to 2.4GHz.
In Settings, please change the Wi-Fi band from 5GHz/5.8GHz to 2.4GHz. (Some phones detect 2.4GHz more easily.)

Please restart both the dash cam and the app.
Please reboot the dash cam, then fully close and reopen the app. After that, please refresh your phone’s Wi-Fi list and look again for the dash cam network.

Please try another phone (if possible).
If you still don’t see the dash cam Wi-Fi, please try searching with a different phone to confirm whether it’s a phone compatibility/setting issue.

If it still doesn’t appear, please contact GKU support.
Please reach out to the GKU support team and share your phone model and iOS/Android version—we’ll help you troubleshoot quickly.

Please try the checks below:

Please make sure you are using the GKU hardwire kit.
Different brands may use different voltage settings or communication methods, and they may not be fully compatible with your GKU dash cam.

Please check the fuse box wiring (very important).

Please connect the Yellow wire to a Constant Power (BAT) fuse — this fuse stays powered even when the engine is off (required for parking mode).

Please connect the Red wire to an ACC/ignition fuse — this fuse is powered only when the ignition is on (for normal driving recording).

Please connect the Black wire to a solid metal ground point on the vehicle chassis.

Please check the app settings after wiring is correct.
Once the hardwire kit is connected correctly, you should see the Parking Mode / Parking Monitor option appear in the GKU GO app settings.

Please don’t worry—this is usually a phone Wi-Fi behavior, not a dash cam issue.

A phone can normally keep only one Wi-Fi connection at a time. If your phone is already connected to your car’s Wi-Fi, it can’t connect to the dash cam Wi-Fi.

Also, the dash cam Wi-Fi does not provide internet. It’s only used for the app (live view/settings) and video transfer. Because of that, your phone may prefer another Wi-Fi network (like your car’s Wi-Fi) that has internet access.

Please try one of these options:

Please turn off your car’s Wi-Fi temporarily, then connect to the dash cam Wi-Fi.

Or please go to your phone Wi-Fi settings and disable Auto-Join for the car’s Wi-Fi (or tap Forget This Network).
