Notice

The user menu is to be set up in non-video mode. If the device is in video mode, please proceed only after stopping the video recording.

Memory Card: Using a new MicroSD card always requires formatting it to your device. Regularly clear the memory card, as continuous video recording for an extended period may produce some protected files that are not subject to long-term protection (these files may not be overwritten during loop recording), and some storage fragments, which must be cleared regularly to save usable storage space.
Time-lapse photography should not be enabled while driving. This function captures images more slowly than normal but plays in speed-up mode, which may affect the integrity and continuity of your video.

On-board Charger: The standard input voltage is configured to 12V. If a voltage is greater than 12V, contact the store of purchase or our customer care via care@rexingusa.com to replace it with a replacement charger.
The features described in this operation manual are available for all products of the same type. The device you buy may be a model with optional or additional functions. Menu operations may vary. Please refer to your actual product.

Pay attention to the mounting position, which must not interfere with driving or lead to unsafe driving operations. Make sure it is safely secured.
A standard 6-meter cable is provided for the rearview camera. It is not recommended to install this type of dash cam if your car is larger than the connection cable range.

Get Started

Memory Card Installation

Step 1. Insert a Memory Card
- You will need to insert a memory card before beginning recording. Push the memory card into the slot until it locks in place.
- The M2 MAX PRO dash cam accepts memory cards with a maximum capacity of 256GB. Depending on the memory card’s manufacturer and type, some cards may not be compatible with the dash cam.
- Using an incompatible card may damage the device, and the memory card, or corrupt the data stored on it. For reliable operation, use a Class 10 memory card with a capacity of at least 32GB.
- Note:
  - DO NOT insert or remove a memory card while the device is in operation.
  - It is recommended that you reformat the memory card every time images are transferred to the computer, or at least once a month.
  - Reformatting a memory card keeps important elements of data and also a cleaned file structure which helps to prevent error messages and missing images. Reformatting also restores the memory card, which can help prevent it from becoming corrupted.

Step 2. Formatting the Memory Card
- Tap the icon to stop recording
- Tap the icon to access the settings
- Toggle down to Format
- Tap OK to format the card

Please format the card on the dash cam before using it. Before formatting a memory card, always remember to make backup copies of all important data stored on the device. The manufacturer’s warranty does not cover loss of data resulting from user actions.

Note Removing the memory card

Before removing a memory card from your dash cam, you must first unmount it for safe removal.

Tap the icon to stop recording
Press and hold the power button to turn off the device
Gently push the memory card in and let go until it releases

Do not remove the memory card while the device is transferring or accessing information. Doing so can result in data loss, corruption, or damage to the memory card or device. Rexing is not responsible for losses that result from the use of damaged memory cards, including the loss of data.

Dash Cam Installation

Strap the dash cam to the rearview mirror of your vehicle with the rubber mounting strap. Adjust the angle of the cameras to ensure that it captures your desired view.
Mount the rear camera as shown below and then connect the rear camera to the main unit. Carefully route the power cable around the door and tuck it under the trim.
- The rearview camera has two wire routing options as shown in the above figure. The first part of both options is characterized by concealing the wire routing against the edges of the door(s).
- The device is configured with a streaming media rearview camera that provides a clear traffic view behind the car. To obtain clearer and more intuitive images, it is recommended to mount the camera above the license plate (as shown by option B).
The device will be automatically powered on when plugged into a 12V accessory socket or cigarette lighter and received a charge (i.e.: the vehicle is started). To turn the device on manually, press and hold the Power button for 3 seconds until the welcome screen appears. The dash cam will automatically start recording when powered on.

The red wire of the rear camera cable provides 12 Volt power to your rear camera. It is not necessary to connect the red wire to the power supply. But if you want to use the parking assist function, it’s recommended to connect to the power source of your reverse lights, so the screen will display the image of the rear camera automatically when the vehicle is in reverse. If you need more installation information, please reach out to care@rexingusa.com for assistance.
- Note: The optional rearview camera is mounted on the rear of the car. Pay attention to its orientation during installation. Plug the rearview camera connector into the corresponding port of the dashcam once the installation is completed. Adjust the position of the lens to ensure that it aligns horizontally with the ground. Start the engine to check the video functionality of the device.
Plug the GPS module into the GPS port and secure the module to a position close to the A-pillar of the car. The antenna receiver side (the side without 3M adhesive) faces the outside and the side with 3M adhesive faces down. It should be properly secured.

When connecting the charger to the vehicle’s 12V DC outlet, be sure to use only a Rexing-approved charger. The charger should be at least a 2.5A charger which is designed and supplied specifically for use with your device. Using an incompatible charger can cause serious personal injury or damage to your device.
- Note: Due to unstable voltages caused by starting the car engine, a voltage fluctuation in some vehicles may be especially obvious. If a flashing screen or some other unforeseeable operating problem occurs when you start the engine, it is recommended to unplug the device from the charger before starting the engine, and then reconnect it after the engine is running.
- Note:
  - Press the Power Button to turn On or Off the screen
  - Press and hold the Power Button for 3 seconds to turn the device on or off
  - We kindly suggest taking a moment to watch our tutorial video. It’s designed to help you have a smooth and successful installation experience. We believe you’ll find it very helpful!

Basic Operation

Video Recording Operation

With a MicroSD card inserted in the device, it will record automatically in video mode after starting. A red indicator will flash in the upper left corner of the screen during video recording.

Home Interface

Choosing the home button brings you to the home screen where you can find the smart drive, file explorer, camera settings, and system settings

Smart Drive

Outline

RCW refers to Rear-End Collision Warning. This warning system will trigger an alert when an object or vehicle is detected by the rear camera.
ADAS, or Advanced Driver Assistance Systems, enhances vehicle safety and supports the driver during operation. Key features include forward collision and lane departure warnings.

BSD refers to Blind Spot Detection, which monitors in real time any vehicle in the blind spots on both sides during driving. It gives an alert to reduce the risk of traffic accidents that are likely to occur when you intend to shift to another lane. It is also called LCA (Lane Change Assist).
RCW and BSD systems may be interfered with by sunlight, inadequate lane lines, rain, and fog, Certain impacts may be affected by these inaccuracies, and some collisions may not be avoidable. Currently, the RCW provides a rate of accuracy between 80 to 90 percent during the daytime and 60 to 70 percent at night. BSD provides a rate of accuracy of around 90 percent during the daytime and around 80 percent at night.

Disclaimer:

The system is a safe driving assistant system and it cannot be used as proof of the liability of traffic accidents.

ADAS / RCW / BSD Calibration

The Rexing M2 Pro MAX is equipped with an auto-calibration feature that activates during the first few minutes of driving, optimizing device performance.

Parking Monitor (On, Off)
- This feature is on when you see the illuminated icon in the status bar on the video recording interface, and it is off when you see the grayed-out icon. When the parking monitor is activated, its standby state will be activated after the engine is turned off. When the car is shocked by an external force and the sensor detects the impact, the system will begin video recording (Intelligent hardwire kit required).

The characteristics and precautions of the parking monitor are as follows:

With the use of the smart hardwire kit (sold separately). After the car engine is turned off, the smart hardwire kit detects the power loss and sends a command to the host device. The system enters a standby state. The Type C plug must always be kept connected to the USB port of the device to ensure a constant power supply to the smart hardwire kit.

In parking mode, the dash cam will turn on, record a 15s video, lock the video, and then turn off again. When a recording is started, the screen does not light up and there is no booting sound.
When the engine is restarted and the parking monitor has been activated, a prompt will be immediately indicated as shown below:

Parking Monitor (Parking Surveillance Mode)

A parking monitor provides surveillance on your parked vehicle.

Vibration Detection

Please select your preferred mode from the camera settings, it will allow the dash cam to switch to parking mode automatically if the vehicle’s engine turns off and switch back to the normal recording after vehicle’s engine turns on.
Rexing Smart Hardwire Kit with Type C port is required (Package Included).
This feature will allow the dash cam to switch to parking mode automatically if the vehicle’s engine turns off and switch back to the normal recording after the vehicle’s engine turns on.
- Note: Please DO NOT ENABLE the Parking Monitor function in the settings of the dash cam WITHOUT connecting a smart hardwire kit. They may cause a malfunction.

Gravity Sensing Record

Gravity Sensing detects significant or sudden movement (such as an impact or collision), and it will trigger an event recording. We suggest setting the “Gravity Sensing” to High sensitivity for Parking Mode Recording.

Note

If you do not use the parking mode function, please change the Gravity Sensing sensitivity to low.
Otherwise, the video will easily be locked and the video cannot be deleted by the loop recording function.
This will cause the memory card to be full of locked videos and cause the recorder to fail to work normally.

Monitoring files are saved in the folders VIDEO_F_LOCK

Check Recorded Files with a Computer

Unplug the used MicroSD card and place it into a card reader
Connect the card reader to the USB port of the computer. Open the removable disc and you will see the following file folders
- PICTURE: Pictures saved
- VIDEO_F/VIDEO_R: Video records of front and rear road tracks
- VIDEO_F_LOCK/VIDEO_R_LOCK: locked video records of front and rear road tracks
- Note: Be careful when deleting any locked video. Important videos, if any, should be backed up.
To play videos or browse pictures, your computer must have the necessary software available.
Backup Files
- If you intend to keep important and memorable videos and pictures for a long time, we suggest that you make a copy of each file from the card to your computer.
- Do not save them in a new folder created in the same storage card; doing so will reduce the available space on the card.
