Installing Your Rexing M3 Mirror Dash Cam
Let’s get this thing into your car. The Rexing M3 installation is pretty straightforward, especially since it simply straps over your existing rearview mirror.
Step 1: Micro SD Card Installation
Before you do anything else, you need to get a memory card in there. This is where all your footage goes! Rexing V2 Pro Review: Is This the Dash Cam You Need for Your Ride?
- Choose the Right Card: You’ll need a Class 10 or higher Micro SD card, with a capacity anywhere from 32GB up to 256GB. Rexing specifically mentions that some cards, like SanDisk Ultra, might not be compatible, so it’s best to avoid those. High-performance cards like Kingston Canvas Go Plus are often preferred.
- Insert It: Push the Micro SD card into the slot on the dash cam until it clicks into place. Make sure the dash cam is off when you do this to avoid any damage.
- Format the Card: This is crucial! Once the card is in, turn on your dash cam and go into the settings menu to format the card directly on the device. Do this even if it’s a brand new card. It helps prevent data corruption and ensures smooth recording. You should probably format it regularly, maybe once a month, to keep things running smoothly.
Step 2: Mounting the Dash Cam
The Rexing M3 is designed to blend in, fitting over your existing rearview mirror.
- Secure the Main Unit: Use the provided rubber straps or bands to securely attach the M3 unit over your vehicle’s rearview mirror. Make sure it’s snug and doesn’t obstruct your view.
- Adjust the Front Camera: Once it’s mounted, adjust the angle of the front camera lens. You want to make sure it clearly captures the road ahead without any obstruction.
Step 3: Connecting the Cameras Rear and Interior
The Rexing M3 is a 3-channel dash cam, meaning it records from three perspectives: front, cabin, and rear.
-
Interior Camera: The interior camera is usually integrated into the main unit itself, so no extra steps there other than aiming it correctly if it’s adjustable.
-
Rear Camera: Route the rear camera cable from the main dash cam unit all the way to the back of your vehicle. This usually involves tucking the cable along the headliner and trim for a clean, discreet look. You can use the cable management tool for this. Mount the rear camera on your rear windshield, or near the license plate, depending on your preference and cable length.
- Optional: Parking Assist Function: The rear camera cable often has a small red wire. If you want the parking assist lines to show up automatically when you put your car in reverse, you’ll need to connect this red wire to your vehicle’s reverse lights’ power source. If you skip this, the rear camera will still record, but you won’t get the automatic parking guidelines.
Step 4: Power Connection
Powering up your Rexing M3 is pretty simple. Rexing V1LG Battery: Everything You Need to Know
- Standard Power: Plug the in-car power cable the one with the GPS logger into your vehicle’s 12V power outlet cigarette lighter socket. Connect the other end to the main dash cam unit.
- Automatic Start: The M3 is designed to power on automatically and begin recording when your vehicle’s ignition turns on and it receives a charge. If you ever need to turn it on manually, just press and hold the Power button for about 3 seconds.
Optional: Rexing Smart Hardwire Kit Installation
If you’re serious about parking surveillance, you’ll want to install a hardwire kit. This allows the dash cam to draw power directly from your car’s fuse box, enabling the 24-hour parking monitor feature even when your car is off. A standard power cable won’t keep the parking mode active unless the car’s ignition is on.
Here’s how a basic hardwire kit installation works refer to the specific Rexing Smart Hardwire Kit instructions for your model:
- Locate Your Fuse Box: This is usually under the dashboard on the driver’s side or in the engine bay. You might need your car’s manual to find it.
- Identify Fuses: You’ll be looking for two types of fuses:
- Switched Fuse: This fuse only gets power when your car’s ignition is on. Connect the red wire from the hardwire kit to this fuse.
- Constant Hot Fuse: This fuse has power all the time, even when the car is off. Connect the yellow wire from the hardwire kit to this fuse.
- Quick Tip: Use a fuse tester to figure out which fuse is which. This step is super important, as reversing the red and yellow wires can lead to problems like the camera staying on constantly or parking mode not working.
- Ground Connection: Connect the black wire from the hardwire kit to a grounded bolt or metal part of your car’s chassis, usually near the fuse box.
- Connect to Dash Cam: Plug the other end of the hardwire kit into your Rexing M3.
- Enable Parking Monitor: Once hardwired, go into your M3’s settings and enable the Parking Monitor feature. You’ll often have options like Time-lapse Recording records at 1 frame per second to save space or G-Sensor Trigger Recording only records when impact is detected.
Note on GPS: The standard M3 power cable includes a GPS logger. If you’re using a hardwire kit, make sure it’s a Rexing Smart Hardwire Kit or one specifically designed to maintain GPS functionality, as some generic kits might cause the dash cam to lose its GPS capabilities.
Diving into Rexing M3 Basic Operations and Settings
Now that your Rexing M3 is installed, let’s explore how to actually use it and customize its settings. The 12-inch IPS touch screen makes navigation really intuitive. Rexing M4 Dash Cam: Your Ultimate Road Guardian?
Screen Navigation and Views
- Turn Screen On/Off: Just tap the screen to turn it on or off. If the icons are hidden, tapping the screen brings them back.
- Switch Camera Views: Swipe left or right on the screen to cycle through different camera views: Front, Rear, Cabin, or a multi-view showing all three.
- Adjust Visual Range: When you’re in a specific camera view, you can swipe up or down to adjust the visual range or angle of that camera. This is super handy for fine-tuning your view.
Key Settings to Configure
Accessing the settings menu is usually done by tapping a gear icon on the screen.
- Resolution: The Rexing M3 records all three channels front, cabin, rear in 1080p Full HD. You might have an option to lower the resolution to 720p if you want to save memory card space, but for clear footage, 1080p is the way to go.
- Loop Recording: This is a must-have feature for any dash cam. With loop recording enabled, the dash cam continuously records, and when your memory card gets full, it automatically overwrites the oldest unlocked video files. You can usually set the clip length to 1, 2, or 3-minute intervals. I usually prefer 3-minute clips. it helps avoid having too many tiny files on the memory card.
- G-Sensor Gravity Sensor: This sensor detects sudden movements or impacts, like in an accident, and automatically locks the current video file, preventing it from being overwritten by loop recording. You can set the sensitivity low, medium, high. If it’s too high, even a bumpy road or a car door closing can trigger it and fill up your card with “event” files. I recommend starting with a medium setting and adjusting if you get too many false positives.
- Parking Monitor Parking Mode: As we talked about, this needs a hardwire kit to work when the car is off. Once enabled, you typically have two main options:
- Time-lapse Recording: Records video at a very low frame rate e.g., 1 frame per second. This saves a lot of storage space and lets you review many hours of parking footage quickly. This is often the recommended option.
- G-Sensor Trigger Recording: The dash cam stays off until it detects an impact or vibration. It then wakes up and records a short video clip.
- Screen Saver: You can set the screen to turn off after a certain period e.g., 1, 3, or 5 minutes while the dash cam continues recording in the background. I like to keep my screen on, but if you prefer a less distracting display, this feature is great.
- Date and Time / Date Stamp: The M3’s built-in GPS usually handles the date and time automatically, which is super convenient. You can also choose whether to display the date and time on your recorded videos. This is crucial for evidence, so I usually leave it on.
- GPS Info & Speed Compensation: The GPS function records your location and speed. If you find the speed displayed on the dash cam doesn’t quite match your car’s speedometer, you might be able to adjust a “speed compensation” setting.
- Language, Volume, Plate Number: You can change the display language, adjust the device’s beeping volume, and even input your vehicle’s license plate number to be stamped on the videos.
- Camera Flip Rear Cam Flip Horizontal/Vertical, Cabin Cam Flip Horizontal: These settings are super useful if your rear or cabin camera ends up being installed upside down or mirrored incorrectly. You can digitally flip the image to get the correct orientation.
Viewing and Managing Your Footage
What’s the point of all this recording if you can’t easily access your videos?
On the Device
- You can playback recorded videos directly on the M3’s touch screen. Just tap the playback icon on the home screen and select the file you want.
On a Computer
For a more detailed review, especially with GPS data, you’ll want to use a computer.
- Using an SD Card Adapter: The easiest way is to remove the Micro SD card from the dash cam, insert it into an SD card adapter, and then plug that into your computer. Your videos are typically stored in a
\Videofolder, with locked “event” files in a\eventfolder. - Using the USB Cable: You can also connect the dash cam directly to your computer using the included USB cable.
- Rexing GPS Player App: To see your driving route, speed, and other GPS information alongside your video, you’ll need the Rexing GPS Player App for your desktop. This app, powered by Google Maps, provides a comprehensive view of your trip data. You can usually find a download link on Rexing’s website or by scanning a QR code in your manual.

Troubleshooting Common Rexing M3 Issues
Even the best tech can sometimes act up. Here are a few common issues users face with Rexing dash cams and how to tackle them:
- “SD Card Error” or Recording Failures: This is one of the most common issues.
- Solution: First, make sure you’re using a compatible Class 10 or higher Micro SD card within the 32GB-256GB range, and avoid those SanDisk Ultra cards if you can. Always format the card directly in the dash cam before its first use and periodically thereafter like once a month. If the card is old or has been used extensively, it might be worn out – try a new one. Also, ensure your dash cam has a stable power connection.
- Dash Cam Not Turning On or Randomly Rebooting:
- Solution: The Rexing M3 is powered by a supercapacitor, meaning it needs to be constantly connected to a power source to operate. The small internal battery is just for emergency file backup. Make sure you’re using the Rexing-approved car charger or a compatible hardwire kit, as your car’s USB port might not supply enough power. Check your cables for damage and try a different power source if possible. Sometimes, an outdated firmware can also cause power issues, so checking for updates is a good idea.
- Poor Video Quality Blurry, Dark, Overexposed:
- Solution: First, ensure your camera lenses front, cabin, rear are clean! A smudge can make a big difference. Check your resolution settings – make sure you’re set to 1080p for all channels. You can also adjust the exposure setting in the menu. if videos are too dark, increase exposure, and if they’re too bright, decrease it.
- GPS Not Working or Inaccurate Speed:
- Solution: Ensure the GPS logger integrated into the power cable for the M3 is properly secured and has a clear view of the sky for optimal signal reception. If you’re using a hardwire kit, double-check that it’s a Rexing Smart Hardwire Kit or one that supports GPS, as some hardwire setups can interfere with GPS functionality if not designed for it. Also, try checking your GPS Info in the settings to see how many satellites it’s connected to.
- Parking Mode Not Activating:
- Solution: Remember, parking mode requires a Rexing smart hardwire kit installation. If you have one, double-check that the red, yellow, and black wires are correctly connected to the appropriate fuses and ground in your fuse box. Sometimes users accidentally reverse the constant and switched power wires, which can prevent parking mode from working. Also, make sure the Parking Monitor feature is enabled in your dash cam’s settings.
- Firmware Updates: Rexing is always improving its products with firmware updates. If you’re experiencing persistent issues that aren’t resolved by basic troubleshooting, check the Rexing website for the latest firmware for your M3. Make sure to follow their instructions carefully, as installing incorrect firmware can render the device unusable.
Maintaining Your Rexing M3
Keeping your dash cam in top shape is pretty easy and ensures it’s always ready when you need it.
- Regular SD Card Formatting: This is probably the most important maintenance tip. Format your Micro SD card at least once a month directly on the dash cam. This helps clear out fragmented files, prevents data corruption, and keeps the card performing optimally. Just remember to back up any important footage first!
- Keep Lenses Clean: Use a soft, lint-free cloth to gently wipe the lenses of your front, cabin, and rear cameras. Dust and smudges can significantly impact video clarity.
- Check Cable Connections: Periodically ensure all cables – power, rear camera, and hardwire kit if applicable – are securely connected and haven’t come loose from vibrations.

Rexing V1 Loop Recording: Your Ultimate Guide to Never Missing a Moment
My Rexing M3 keeps turning off or rebooting. What’s wrong?
This often happens because the dash cam isn’t getting a stable or sufficient power supply. The Rexing M3 uses a supercapacitor and needs to be continuously plugged in to work. Make sure you’re using the original Rexing car charger or a compatible hardwire kit, as your car’s built-in USB ports might not provide enough power. Check the power cable for any damage, and try a different 12V power outlet in your car if you have one. A depleted internal battery which is mainly for emergency file backup or outdated firmware can also contribute to this.

This app will display your route on a map, your speed, and other details synchronised with your video. Just make sure the GPS logger is positioned correctly for optimal signal reception.
Can I connect the Rexing M3 to my phone or use an app?
While the primary way to manage and view footage with GPS data is through the desktop Rexing GPS Player App, Rexing often offers firmware updates and support through their website. The M3 generally doesn’t have Wi-Fi for direct phone app connectivity for live viewing or immediate downloads like some other models, but you can always take the Micro SD card out to review footage on a computer or use the included USB cable to connect the dash cam to your computer.
My rear camera image is upside down or mirrored. How do I fix it?
Don’t worry, this is a common fix! Head into your Rexing M3’s settings menu. You should find options like “Rear Cam Flip Horizontal” and “Rear Cam Flip Vertical” and similar for the cabin camera. You can toggle these settings on or off to correctly orient the image on the screen, making sure it looks just right, whether you installed the camera upside down or not.
