Three steps to get going.
Set up while parked. Back up anything you want to keep before formatting a memory card.
01 / PREPARE
Fit the memory card
Use a Class 10 microSD card, 32–256GB. Switch the camera off before inserting or removing it. On the touchscreen, stop recording, open Settings, select Format, and confirm.
02 / CONNECT
Mount & supply power
Secure the camera to your mirror with its straps. Connect the supplied vehicle charger to the Type-C power port, then connect the rear-camera cable to the AV port. Keep cables clear of airbags and moving parts.
03 / CHECK
Check both views
Adjust the lenses while parked. Swipe left or right to change between front and rear views. A flashing red indicator shows recording. Check the date, time and a short test recording before driving.
Use the supplied Rexing power adapter. A connector that fits does not guarantee that an unrelated adapter can supply the camera correctly.
02 / Everyday operation
Your screen is the control center.
Tap the screen to reveal the controls. Make adjustments while your vehicle is safely parked.
A dark display alone does not mean recording has stopped. Check the recording indicator or review a test clip.
Power & display
Hold the power button for about three seconds to turn the device on or off. A short press toggles the display backlight; tap the screen to wake the display.
Front, rear & driver assistance
Swipe horizontally between camera views. Calibrate blind-spot and rear-end collision warnings before relying on them. These alerts assist you; always check your surroundings directly.
Play back & preserve clips
Open File Explorer. Look for VIDEO-F, VIDEO-B, VIDEO-LOCK or IMAGE. Copy important footage before formatting. Locked clips also consume storage, so back them up and remove unneeded files.
03 / Connected features
Connect your phone.

- Open Rexing ConnectChoose Connect to access the camera. Download useful clips to your phone before sharing them.
If the phone reports “no internet,” it may still be connected correctly to the camera. Keep that local Wi-Fi connection active while using the app.
04 / Protection while parked
The kit changes the setup.
Engine-off recording needs a compatible hardwire kit. Check the kit’s label and the M2 Max power connector before purchasing or installing.
Intelligent Hardwire Kit
The guide identifies UPC 810046603178 for motion detection. With this kit, leave the camera’s Parking Mode setting OFF, as instructed in the M2 Max guide.
Motion kit: camera Parking Mode OFFWhy parking recording may stop
When a hardwire kit’s low-voltage protection cuts power, the camera cannot record or wake for another event. Frequent triggers can use up the available battery reserve. Restore the vehicle battery’s charge and check the kit’s wiring and settings; do not bypass the protection.
Normal driving
Confirm reliable vehicle power and recording before testing parking behavior.
Engine off
Test the kit’s intended trigger while safely parked. Impact recording may occur without lighting the screen.
Reverse assistance
The optional rear red-wire connection switches the reversing view. It is separate from engine-off parking monitoring.
05 / Troubleshooting
Find your next step.
Start with power, storage and the selected mode. These checks help narrow down the cause.
The camera will not turn on. What should I check?
Try the supplied charger in a known-working vehicle outlet. Check the Type-C connection and hold the power button. For a hardwired installation, check the fuse, ground and kit status; low-voltage protection can intentionally remove power. Contact support if normal vehicle power does not restore operation.
Why does it show a card error or stop recording?
Back up recordings, then format the card in the camera while recording is stopped. Confirm the card is suitable and within the supported capacity. If errors continue, try a known-good card. Preserve any footage needed before replacing or reformatting it.
Why is the rear view missing?
Turn the camera off and check the rear cable connections. Restart and swipe left or right to select the rear view. For automatic reversing view, have the optional trigger wiring checked by a qualified installer.
Why does my phone disconnect from the camera?
Reconnect to the camera’s Wi-Fi and reopen Rexing Connect. Phones may switch to another network when the camera connection has no internet. Keep the camera connection selected and grant the app the local-network permissions your phone requests.
Can I use another model’s firmware or instructions?
No. Use the M2 Max guide and confirm the exact model and current firmware with support before updating. The M2, M2 Max and M2 Max Pro are different models.
Parking mode does not wake the camera. What next?
Confirm which kit is installed and use its matching settings. Check whether the kit still supplies power after ignition-off. If low-voltage protection has activated, charging the vehicle battery is the next step. Send support the kit label, wiring details and camera settings if the issue continues.
