Getting to Know Your Rexing M2: Key Features

Before we get our hands dirty with installation, let’s quickly run through what makes the Rexing M2 tick. Knowing its capabilities will help you appreciate why we set things up a certain way.

The Rexing M2 is generally a dual-channel mirror dash cam, meaning it records both the front and rear of your vehicle simultaneously. Most standard M2 models capture footage at Full HD 1080p resolution for both cameras, though some variants like the M2 MAX can go up to 4K for the front.

Here are some of the standout features you’ll find:

• 12-inch IPS Touch Screen Display: This isn’t just a regular mirror. it’s a vibrant touchscreen that gives you a wide, real-time view of traffic behind you and lets you navigate settings easily with a swipe of your finger.
• Dual-Channel Recording: As mentioned, you get coverage for both the front and rear of your vehicle, which is super important for comprehensive incident documentation.
• Built-in GPS Logger: This handy feature tracks your driving route, speed, and location, stamping this data onto your recordings. It’s incredibly useful for providing context if you ever need to review footage.
• G-Sensor Gravity Sensor: This smart little sensor detects sudden movements or impacts, like a collision. When it does, it automatically locks the current video file, preventing it from being overwritten by loop recording.
• Loop Recording: You never have to worry about your memory card filling up. When it reaches its capacity, the M2 automatically overwrites the oldest, unlocked files, ensuring continuous recording.
• Parking Monitor Parking Mode: This feature is a lifesaver for when you’re parked. With it enabled, the dash cam can automatically turn on and record a short video if it detects vibration or motion, keeping an eye on your car 24/7.
• Blind Spot Detection BSD & Advanced Driver Assist System ADAS: Some M2 models, like the “M2 Smart BSD ADAS Dual Mirror Dash Cam,” include advanced radar sensors to help monitor your blind spots and even assist with lane changes by alerting you when it’s safe. ADAS features can also help detect nearby cars or obstacles.
• Auto Backup Camera: The rear camera footage can often double as an auto backup camera, giving you a clear view when you’re reversing, eliminating blind spots.

Knowing these features, you can see why the M2 is more than just a camera. it’s a robust security system for your car.

Rexing M2 Dash Cam Installation: Getting It in Your Car

Installing your Rexing M2 might seem a bit daunting at first, especially with all those wires, but trust me, it’s totally doable. We’ll break it down step-by-step to make it as straightforward as possible.

Step 1: Mount the Main Dash Cam Unit

The M2 is a mirror dash cam, so it straps right over your existing rearview mirror. Mastering Your Rexing Dash Cam App: A Complete Guide

1. Strap It On: Use the provided rubber mounting straps to securely attach the main dash cam unit to your car’s rearview mirror. Make sure it’s snug and doesn’t wiggle.
2. Adjust the Angle: Once it’s in place, adjust the angle of the front camera lens. You want it to capture a clear, unobstructed view of the road ahead, typically centered. Remember, this camera can be angled independently of your actual rearview mirror.

Step 2: Powering Up Your Dash Cam

This is where the main unit gets its juice.

1. Connect the Power Cable: Take the in-car power cable and plug one end into the Type-C port on your dash cam.
2. Plug into 12V Outlet: Route the other end of the power cable to your car’s 12V power outlet cigarette lighter socket and plug it in.
3. Cable Management: This is crucial for a clean look and to prevent distractions. Use the included cable management tool or just your fingers to tuck the power cable neatly along the edge of your windshield, down the A-pillar the frame next to your windshield, and under the dashboard trim towards your power outlet. Most car interiors have little gaps where you can tuck wires, making them almost invisible.

Step 3: Installing the Rear Camera

This part can take a little more effort, but it’s worth it for that rear coverage.

1. Route the Rear Camera Cable: This is often the most time-consuming part. You’ll connect the rear camera cable to the main unit, then carefully route it along your vehicle’s headliner the ceiling, down the side pillars, and towards the back of the car. You can usually tuck it under the trim panels for a professional look. For the very back, you have a couple of options: run it through the trunk lining or even consider mounting it above your license plate for a clearer view, which might involve a bit more work.
2. Mount the Rear Camera:
   • Inside the Rear Window: Many people mount it at the top of the rear window. Clean the surface thoroughly before sticking it on.
   • Outside Above License Plate: For some models, or if you prefer a backup camera view, you can mount it outside your car, typically above the license plate. If you go this route, ensure the area is clean before applying any adhesive. You might also need to find a grommet or drill a small hole if comfortable to pass the cable through to the car’s interior.
3. Connect the Red Wire Optional but Recommended for Parking Assist: The rear camera cable often has a small red wire. If you want the parking assist function where the screen automatically displays the rear camera image when you shift into reverse, you’ll need to connect this red wire to the power source of your car’s reverse lights. This usually involves tapping into the reverse light wiring. If you’re not comfortable with this, a professional can easily do it, or you can skip it and still have rear recording, just without the automatic parking assist.

Step 4: Connecting the GPS Module

The GPS logger usually plugs into a dedicated GPS port on the main dash cam unit.

1. Plug It In: Connect the external GPS logger to the designated GPS port.
2. Position It: Secure the module to a position near your car’s A-pillar, ensuring the antenna receiver side the side without adhesive faces outwards for the best signal reception.

Once everything is plugged in and tucked away, start your engine to make sure the device powers on automatically and starts recording.

Rexing M2 Dash Cam Setup: First Power On & Essential Settings

With your M2 physically installed, it’s time to get it configured. This is where we make sure it records exactly how you want it to.

Step 1: Inserting and Formatting Your SD Card

This is probably the most critical step for proper recording. Without a good SD card, your dash cam won’t work reliably, and you might encounter “rexing dash cam memory error” or “rexing dash cam not recording” issues.

1. Get the Right Card: The Rexing M2 requires a micro SD memory card with a Class 10 / UHS-I or higher speed rating. It supports cards up to 256GB. It’s really important to use a high-endurance card specifically designed for dash cams, as they withstand constant overwriting better. Brands like Kingston Canvas Go Plus are often preferred over others like SanDisk Ultra, which Rexing sometimes doesn’t recommend for reliability in dash cams.
2. Insert the Card: Gently push the microSD card into the designated slot until it clicks and locks into place. Never insert or remove the memory card while the device is in operation, as this can corrupt the card or damage the dash cam.
3. Format the Card Crucial!: This step prepares the card for your specific dash cam.
   • Power on your dash cam.
   • Stop any ongoing recording tap the record icon if it’s flashing.
   • Go to the dash cam’s Settings menu.
   • Look for the “Format” option sometimes found under “System Setup” or “Driving Setup”.
   • Confirm the format. This will erase all data on the card and optimize it for your M2. Always format the card inside the dash cam, not on a computer, for best compatibility.

Step 2: Basic Settings You Need to Adjust

Once the card is formatted, let’s tweak some settings.

1. Date and Time: This is super important for accurate incident logs. Navigate to the “Date/Time” setting and set it correctly.
2. Video Clip Length Loop Recording: The M2 records in intervals. You can usually choose 1, 2, or 3-minute intervals. This setting determines the length of each video file.
3. Resolution: For the M2, you’ll likely have options for 1080p for both front and rear. Stick with the highest resolution available for the clearest footage.
4. G-Sensor Sensitivity: Remember the G-sensor that locks files on impact? You can adjust its sensitivity Low, Medium, High, Off.
   • Driving: For everyday driving, a “Medium” or “Low” setting is usually fine to avoid locking files from minor bumps or potholes.
   • Parking Mode: If you’re using parking mode, setting the G-sensor to “High” sensitivity is often recommended to capture any slight vibrations or impacts while parked. Be careful: if the G-sensor is too sensitive in normal driving mode, your card can fill up with locked files that won’t be overwritten by loop recording, leading to memory errors.

Step 3: Getting Familiar with the Touch Screen

The M2’s 12-inch IPS touch screen is pretty intuitive.

• Switching Views: You can usually swipe left or right on the screen to switch between views front, rear, or split-screen.
• Adjusting Visual Range: Swiping up or down can adjust the visual range of each camera.
• Accessing Icons: If the icons are hidden, just tap the screen to bring them up.
• Start/Stop Recording: There will be an on-screen icon for this. The dash cam should automatically start recording when powered on, but you can manually stop/start if needed.

Using Your Rexing M2 Daily: More Than Just Recording

Your M2 isn’t just about passive recording. it’s an active tool for your driving safety.

Recording Modes

Beyond continuous loop recording, your M2 offers specific modes:

• Normal Recording: This is your everyday driving footage, constantly looping over old files.
• Emergency Recording: Triggered by the G-sensor during an impact, these files are locked and protected from being overwritten.
• Parking Monitor Recording: As discussed, this activates when your car is parked and the engine is off, recording if an event is detected. You might need a hardwire kit for continuous parking mode.

Connecting with the Rexing Connect App

Your M2 features Wi-Fi connectivity, which is awesome for reviewing and saving footage without pulling out the SD card.

1. Download the App: Grab the “Rexing Connect” app from your smartphone’s app store available for iOS and Android.
2. Enable Wi-Fi on Dash Cam: Go into your M2’s settings and turn on the Wi-Fi function. The Wi-Fi name SSID and password will appear on the screen.
3. Connect Your Phone: On your smartphone, go to your Wi-Fi settings, find the dash cam’s Wi-Fi network name, and connect to it using the password displayed on the dash cam screen.
   • Quick tip: Some phones might give you a “no internet” warning since it’s connecting directly to the camera, not your home Wi-Fi. Just choose to “Keep Trying Wi-Fi” or ignore the warning.
4. Open Rexing Connect App: Once connected, open the app. You should now be able to see a live view, access your recordings, and download them directly to your phone. This is super convenient if you need to quickly show footage to law enforcement or an insurance agent.

Accessing Your Footage

You have a few ways to check your recordings:

1. On the Dash Cam Itself: Use the playback mode on the M2’s touchscreen to review files.
2. Via Rexing Connect App: As just described, this is often the easiest and quickest method.
3. Through Your Computer: Remove the microSD card from the dash cam and insert it into a card reader connected to your computer. You can then access the video files directly. For GPS data playback, Rexing usually provides a separate GPS player software for Windows and Mac, specifically for M-series dash cams.

Troubleshooting Common Rexing M2 Issues

Even the best tech can have its hiccups. Here are some common problems Rexing M2 users face and how to fix them.

Rexing Dash Cam Not Recording

This is a big one. if your dash cam isn’t recording, it’s not doing its job.

• SD Card Full/Corrupted: This is the most frequent culprit. Even with loop recording, if your G-sensor sensitivity is too high, it can fill the card with locked files that won’t be overwritten.
  • Solution: Format the SD card regularly within the dash cam’s settings. I’d recommend doing it at least once a month, especially if you’re driving a lot. Also, ensure you’re using a high-quality, high-endurance Class 10/UHS-I or U3 microSD card up to 256GB. If the card is old or faulty, replace it.
• Improper Formatting: If you formatted the card on your computer, it might not be compatible.
  • Solution: Always format the memory card inside the dash cam.
• Power Issues: Insufficient or unstable power can interrupt recordings.
  • Solution: Make sure your power cable is securely connected and isn’t faulty. Use the Rexing-approved charger.
• Loop Recording Off: Double-check your settings to ensure loop recording is enabled.
• Firmware Problems: Outdated or buggy firmware can cause recording failures.
  • Solution: Visit the RexingUSA website for any available firmware updates and follow their instructions carefully.

Rexing Dash Cam Memory Error

This usually points back to the SD card.

• Incompatible or Faulty SD Card: As mentioned before, some cards, even branded ones, just don’t play nice with dash cams due to the constant read/write cycles.
  • Solution: Try a different high-endurance, Class 10/UHS-I or U3 microSD card from a reputable brand like Kingston Canvas Go Plus.
• Card Not Inserted Correctly: Sometimes it’s as simple as the card not being fully seated.
  • Solution: Push the card firmly until it clicks. If you’re struggling, a coin can help gently push it in.
• Card Needs Formatting:
  • Solution: Go to your dash cam’s settings and format the memory card.

Rexing Dash Cam Not Turning On / Keeps Rebooting

Power problems are often at play here.

• Insufficient Power: The internal battery in most dash cams is for emergency recording, not continuous operation. They need constant power from your car.
  • Solution: Ensure the dash cam is continuously connected to a reliable 12V power source using the included car charger or a hardwire kit. Try a different power source or cable if you suspect a fault.
• Depleted Internal Battery: If it keeps rebooting, the small internal battery might be low.
  • Solution: Ensure it’s connected to power for a while to let the internal battery charge. If the issue persists, it might be a faulty battery or charger.
• Firmware Glitch:
  • Solution: A firmware update or a factory reset found in settings can sometimes resolve unexpected reboots.

Rexing Dash Cam Rear Camera Not Working

• Loose Connection: The cable connecting the rear camera to the main unit might be loose or damaged.
  • Solution: Check both ends of the cable to ensure they’re securely plugged in.
• Faulty Cable or Camera:
  • Solution: If connections are good, the cable or the rear camera itself might be faulty. Contact Rexing support if it’s still under warranty.
• Firmware Issue: Sometimes firmware updates can cause specific features like the rear camera to stop working.
  • Solution: Check Rexing’s support site for specific firmware versions or solutions.

Rexing Dash Cam Wi-Fi Not Working

• App Permissions: Sometimes your phone’s operating system might restrict the app.
  • Solution: Check your phone’s app settings to ensure “Rexing Connect” has all necessary permissions, especially for Wi-Fi and local network access. Some users found Android put the app to sleep or removed permissions.
• Incorrect Connection Steps:
  • Solution: Make sure you’ve enabled Wi-Fi on the dash cam first, then connected your phone’s Wi-Fi directly to the dash cam’s network SSID and password displayed on the dash cam screen, and then opened the Rexing Connect app and tapped the connect icon.
• Wi-Fi Interference: Other wireless devices or signals could be causing interference.
  • Solution: Try connecting in a different location.

Is Rexing a Good Dash Cam Brand?

This is a question many people ask, and it’s a fair one. My take? Rexing offers a mixed bag, but generally, they provide a lot of value for their price point, especially if you’re looking for feature-rich mirror dash cams.

On the positive side, Rexing dash cams, like the M2, are known for their:

• Feature-Rich Design: They pack in things like dual-channel recording, GPS, Wi-Fi, G-sensor, parking mode, and even advanced driver assistance systems in some models.
• High-Resolution Video: Many models offer clear video quality, with options for 1080p, 2K, or even 4K in their higher-end devices. This is essential for capturing details like license plates.
• Ease of Use: Their touchscreens and relatively straightforward installation especially for the mirror-style cams are often praised.

However, you’ll also find some users mentioning concerns. On forums like Reddit, some people have reported issues with reliability over time, video quality not always meeting expectations for license plate readability in certain conditions, or frustrations with app connectivity. A common theme is the importance of using a high-quality, dash-cam-specific SD card to avoid recording issues, as generic cards can lead to problems. Rexing customer support

Overall, if you’re looking for a dash cam that offers a lot of features without breaking the bank, Rexing is a competitive option. Just remember that, like with any tech, some users have different experiences. The key is to follow the setup and maintenance guidelines, especially regarding your SD card, to get the most out of your device.

Frequently Asked Questions

How do I hardwire my Rexing M2 dash cam?

To hardwire your Rexing M2 dash cam, you’ll need to purchase a separate Rexing hardwire kit either a Smart Hardwire Kit for auto event detection or an Intelligent Hardwire Kit for collision & motion detection. The general process involves connecting the hardwire kit directly into your car’s fuse box. This typically requires identifying a constant fuse for 24/7 parking surveillance and an accessory fuse that only powers on with the ignition. The hardwire kit will then plug into the dash cam, freeing up your cigarette lighter port and providing continuous power for advanced parking modes. Rexing provides tutorial videos on their website and YouTube channel for a step-by-step guide on how to install their hardwire kits. If you’re unsure about electrical work, it’s always best to have a professional install it.

What kind of SD card should I use for my Rexing M2?

You should use a microSD card with a Class 10 / UHS-I or higher speed rating, and it should be specifically designed for dash cam use often labeled “High Endurance”. The Rexing M2 supports cards up to 256GB. Using a high-endurance card is crucial because dash cams constantly write and overwrite data, which can quickly wear out standard microSD cards. Some users and Rexing itself have noted that certain popular brands like SanDisk Ultra might not be as reliable in dash cams, with others like Kingston Canvas Go Plus often performing better.

How do I format the SD card on my Rexing M2?

Formatting the SD card is a critical step. First, ensure your dash cam is powered on and stop any active recording. Then, navigate to the dash cam’s Settings menu on the 12-inch touch screen. Look for an option like “Format” or “Format SD Card” it might be under “System Setup” or “Driving Setup”. Select this option and confirm. The dash cam will then erase all data on the card and optimize it for use with your device. It’s important to always format the card directly in the dash cam, not on a computer, for best compatibility and to prevent “memory errors.” Rexing Companies Reviews: Are These Dash Cams the Right Fit for Your Ride?

Why is my Rexing M2 dash cam not recording?

There are several common reasons why your Rexing M2 might not be recording:

1. SD Card Issues: The most frequent cause. The card might be full of locked files due to a high G-sensor sensitivity in normal driving, corrupted, incompatible, or improperly formatted.
2. Power Supply Problems: Insufficient or unstable power can interrupt recordings.
3. Loop Recording Disabled: Ensure the loop recording feature is turned on in your settings.
4. Firmware Glitches: Outdated or faulty firmware can sometimes lead to recording failures.

To troubleshoot, first format your SD card in the dash cam, ensure you’re using a compatible high-endurance Class 10/UHS-I or U3 card, check your power connection, and confirm loop recording is active. If problems persist, consider checking for a firmware update.

How do I connect my Rexing M2 to Wi-Fi?

Connecting your Rexing M2 to Wi-Fi allows you to view and download footage via the Rexing Connect app. Here’s how:

How often should I format the SD card in my Rexing M2?

It’s highly recommended to reformat your microSD card at least once a month. This practice helps maintain the card’s health, clears out any accumulated file fragments, and ensures consistent, reliable recording. Dash cams constantly write and rewrite data, which can lead to card degradation and performance issues over time. Regular formatting from within the dash cam itself keeps everything optimized.

Where can I download the Rexing M2 manual PDF?

You can usually find the official Rexing M2 manual PDF on the RexingUSA website under their support or downloads section. Many product support pages will have a direct link to the user manual. Alternatively, websites like ManualsLib also host the Rexing M2 user manual for free viewing and download.
