Key Features That Make the M3 Shine

The Rexing M3 isn’t just a pretty face. it’s packed with features that make it a seriously powerful tool for vehicle security. Let’s break down what makes this dash cam stand out.

Triple-Vision Protection: Front, Cabin, Rear

This is probably the M3’s biggest flex: three cameras recording simultaneously. Mastering Your Rexing V1-4K: The Ultimate User Manual Guide

  • The front camera captures the road ahead with a wide 170° angle, giving you a broad view of traffic.
  • The cabin camera keeps an eye on the interior. This is a huge bonus for rideshare drivers or anyone who wants an extra layer of security for their passengers and belongings. What’s cool here is that the cabin camera often comes with night vision, letting it see clearly even in complete darkness. Plus, it’s pretty adjustable, so you can point it exactly where you need to.
  • The rear camera handles what’s behind you, also with a 170° wide angle, and it’s even waterproof, meaning you can install it inside or outside your vehicle for the best possible view.

All three cameras record in 1080p Full HD, which means you get crisp, clear video, letting you make out crucial details like license plates or faces.

The Big Picture: 12-inch IPS Touch Screen

Forget tiny, fiddly screens. The M3 rocks a generous 12-inch IPS touch screen that replaces your traditional rearview mirror. This display is super intuitive – you just swipe and tap to navigate menus, switch between camera views front, cabin, rear, or a split view, and adjust settings.

Beyond just controls, this screen acts as a stream media display, showing you real-time video from the rear camera. This can virtually eliminate blind spots and give you a much wider, clearer view of what’s behind you, especially helpful in bad weather or at night when a traditional mirror might be lacking. It even functions as an auto-backup camera, displaying parking guidelines when you shift into reverse, making parking maneuvers much easier and safer.

Smart Surveillance: GPS and Parking Monitor

The M3 isn’t just about recording. it’s about smart recording.

  • Built-in GPS: This isn’t just for show. The integrated GPS module records your driving location, speed, and time data. This information can be a lifesaver if you ever need to provide evidence in an accident, proving exactly where you were and how fast you were going. You can review this data using the Rexing GPS Player App on your computer, which overlays your route on Google Maps. Just a heads-up: if you use the hardwire kit for power instead of the cigarette lighter, the GPS might lose its functionality.
  • Parking Monitor: This is where the M3 really steps up its game for vehicle security. With the parking monitor enabled, your dash cam keeps watching even when your car is off and parked. If it detects any vibration or impact, it automatically turns on and starts recording, giving you surveillance against potential damage or theft. To use this feature, you’ll need the Rexing hardwire kit, which powers the dash cam continuously from your car’s battery without draining it completely. You can typically choose between a G-sensor trigger recording records only upon impact or time-lapse recording records continuously at a low frame rate to save space.

Reliable Recording: G-Sensor & Loop Recording

These are standard but crucial features for any good dash cam. Decoding the Rexing R4 Dash Cam: Your Ultimate Road Trip Companion

  • G-Sensor Gravity Sensor: This clever sensor detects sudden movements or impacts, like a collision. When it senses an event, it automatically “locks” the current video segment, protecting it from being overwritten. This means critical evidence is safely stored and won’t be lost.
  • Loop Recording: You never have to worry about your memory card filling up. The M3 records video in continuous loops you can usually set these to 1, 2, or 3-minute intervals. When your Micro SD card reaches its storage limit, the dash cam automatically overwrites the oldest, unlocked recordings with new ones, ensuring uninterrupted coverage.

Other Noteworthy Features

  • Adjustable Camera Angles: Not just the main unit, but the cabin camera can be moved around to get the best possible view, even turning almost 90 degrees to capture interactions outside your side windows.
  • Micro SD Card Support: The M3 supports high-speed Class 10 or higher Micro SD cards up to 256GB, giving you plenty of storage for your recordings.
  • Audio Recording: The dash cam can record both video and audio, which can be an important piece of evidence in certain situations. You can toggle this on or off in the settings.
  • Adjustable Parking Guidelines: For the backup camera function, you can actually tweak the parking guidelines on the screen to perfectly match your vehicle, which is super handy for precise parking.

Getting Set Up: Rexing M3 Installation Made Easy

Installing your Rexing M3 might seem a bit daunting at first glance, especially with three cameras, but it’s actually pretty straightforward. Think of it like a fun weekend project for your car!

What You’ll Need

Before you start, gather these essentials:

  • Your Rexing M3 Mirrored Dash Cam Unit including the interior camera, rear camera, GPS module, power cable, rear camera cable, and mounting straps/bands.
  • A high-speed Micro SD card Class 10 or higher, at least 32GB, up to 256GB. This is crucial and usually not included.
  • A trim removal tool often included with Rexing products and cable hiding clips for a neat install.
  • Maybe some zip ties for extra cable management.
  • A microfiber cloth to clean surfaces before mounting.

Step-by-Step Basic Installation

This is for powering your M3 through your car’s 12V cigarette lighter outlet.

  1. Insert the Micro SD Card: Make sure your car is off. Gently push the Micro SD card into the designated slot on the dash cam until it clicks into place. Pro tip: Format the card directly on the dash cam before its first use, and regularly, like once a month, to keep things running smoothly.
  2. Mount the Dash Cam: The M3 is designed to fit right over your existing rearview mirror. Use the provided rubber straps or bands to securely fasten it. Adjust the front camera lens so it clearly captures the road ahead. You want it firmly attached and not obstructing your view.
  3. Connect the Cameras and GPS:
    • Plug the interior camera into the main dash cam unit and position it to get a good view of the cabin.
    • Route the rear camera cable from the main unit to the back of your vehicle. You can tuck this cable neatly along the headliner and down the A-pillar, then along the floor sills to the rear. Mount the rear camera on your rear windshield or near the license plate – it’s waterproof, so you have options!
    • Plug the GPS module into its port on the dash cam. Position it where it has a clear view of the sky for optimal signal reception, often near the A-pillar or tucked away.
    • Optional for Parking Assist: The rear camera cable has a small red wire. If you want the parking assist guidelines to appear automatically when you put your car in reverse, you can connect this red wire to your vehicle’s reverse light power source.
  4. Power Connection: Plug the included car charger into your vehicle’s 12V power outlet the cigarette lighter socket. The dash cam should automatically power on when you start your vehicle and begin recording. To manually turn it on, just press and hold the power button for about 3 seconds.

Advanced Power: Rexing M3 Hardwire Kit Installation

If you’re serious about your dash cam’s capabilities, especially its parking monitor features, a hardwire kit is a must. This provides continuous power, even when your car is off, and prevents your car battery from draining by cutting power if it gets too low. Plus, it offers a much cleaner, more discreet installation without a cable dangling from your cigarette lighter. Rexing L4 Dash Cam: Your All-Around Road Guardian

Why Hardwire?

  • 24/7 Parking Surveillance: Enables the parking monitor feature to protect your car while parked.
  • Cleaner Look: No visible wires running from your cigarette lighter.
  • Battery Protection: Smart hardwire kits include low-voltage protection to prevent your car battery from dying.

Understanding the Wires:
A standard hardwire kit usually has three wires:

  • Red ACC/Switched Power: Connects to a fuse that only gets power when your car’s ignition is on Accessory power.
  • Yellow B+/Constant Power: Connects to a fuse that always has power, even when the car is off.
  • Black GND/Ground: Connects to a metal bolt or screw on the car’s chassis for grounding.

General Steps for Fuse Box Connection:

  • Locate Your Fuse Box: This is usually under the dashboard, on the side of the dash when the door is open, or sometimes under the hood. Consult your car’s manual if you’re unsure.
  • Identify Suitable Fuses: You’ll need a fuse tester a small, inexpensive tool to find a switched power fuse and a constant power fuse. Turn your car on, test fuses until you find one that’s live. Turn your car off, test again to confirm it’s switched. Repeat for constant power should be live with the car off.
  • Connect the Wires: Use “add-a-circuit” fuse taps not usually included with the hardwire kit itself, but essential for a safe and easy connection to the fuse box. These taps allow you to connect the hardwire kit’s wires to existing fuse slots without cutting any original wiring.
    • Attach the red wire to your chosen switched fuse using a fuse tap.
    • Attach the yellow wire to your chosen constant power fuse using a fuse tap.
    • Secure the black ground wire to a clean, unpainted metal bolt on your car’s frame.
  • Route Cables: Carefully route the hardwire kit’s cable from the dash cam, along the headliner, down the A-pillar, and to the fuse box, tucking it behind trim panels using your trim removal tool.
  • Test Everything: Once connected, start your car to ensure the dash cam powers on. Turn your car off and wait a moment to see if the parking mode activates if enabled or if the dash cam stays on as expected for continuous recording.

Troubleshooting Tip for Hardwiring: If you find the camera stays on even when your engine is off, or the parking mode isn’t working, you might have accidentally swapped the red and yellow wires. A common mistake is connecting the yellow constant to a switched fuse and vice-versa. Double-check your fuse connections with a fuse tester.

Optimizing Your Experience: Rexing M3 Settings and Tips

Once your Rexing M3 is physically installed, it’s time to fine-tune it to get the best performance and make it truly your own. The 12-inch touchscreen makes navigating these settings a breeze.

Resolution and Loop Recording

  • Resolution: The M3 offers 1080p for all three cameras. While you might see options for lower resolutions like 720p, I’d strongly recommend sticking with 1080p Full HD for all channels. This gives you the highest quality footage, which is vital for capturing details like license plates or facial features, especially in an incident.
  • Loop Recording: You can set video clip lengths to 1, 2, or 3 minutes. There’s no “wrong” choice here. it really depends on your preference. Some people like shorter clips for easier review, while others prefer longer ones to have fewer individual files. I personally find 3-minute clips a good balance.

G-Sensor Sensitivity

The G-Sensor detects impacts. You’ll typically find settings like Low, Medium, or High sensitivity, or you can even turn it off.

  • If it’s too sensitive High, sudden bumps or hard braking might trigger it, filling your card with locked files.
  • If it’s too low Low, it might miss minor impacts.
  • Experiment to find the sweet spot for your driving style and vehicle. Most people find “Medium” works well.

Parking Mode Settings

Remember, you need the hardwire kit for this to work.

  • Parking Monitor Duration: You can usually set how long the parking monitor stays active, like 2, 8, 12, or 24 hours. I typically run mine on 24 hours for continuous coverage, but you can adjust based on your needs.
  • Parking Mode Type:
    • G-Sensor Trigger Recording: The dash cam stays off until an impact is detected, then records a short clip. This saves storage space and battery.
    • Time-Lapse Recording: The dash cam continuously records at a very low frame rate e.g., 1 frame per second, compressing many hours of footage into short, easily reviewable clips. This is fantastic for seeing longer events unfold. I often prefer the G-sensor trigger for parking mode, as it’s more direct for impact evidence.

Display & Audio

  • Screen Saver: You can set the screen to turn off after 1, 3, or 5 minutes, or keep it on constantly. This lets the dash cam record “in stealth mode” without the bright display being distracting or obvious. I like to keep the screen saver off because I like to see what’s going on, but it’s totally up to you.
  • Volume: Controls the volume for playback and startup sounds.
  • Audio Recording: The M3 can record audio inside the cabin. You can switch this on or off depending on your preference. Having audio can be critical evidence in an incident.

Time, Date, and Car OSD

  • Time Settings: Since the M3 has GPS, it usually pulls the date and time automatically. Make sure your time zone is set correctly, and consider enabling daylight saving time if applicable.
  • Date Watermark: This adds the date and time to your recorded video. I recommend keeping this on, as it provides undeniable proof of when footage was captured.
  • Car OSD On-Screen Display: You can input your license plate number or a custom name to be displayed on the video. This adds another layer of identification and evidence.

Reverse Guidelines

When you’re in reverse, the M3 can show parking guidelines. What’s neat is you can adjust these guidelines right on the screen to match your vehicle perfectly, helping you park with more precision.

Maintenance Tips

  • Format Your SD Card Regularly: This is a big one! Reformatting your Micro SD card at least once a month helps maintain its performance, prevents errors, and keeps the file structure clean. Always back up important videos before formatting!
  • Check for Firmware Updates: While not explicitly detailed in the provided search results, it’s generally good practice to periodically check Rexing’s website for any firmware updates. These can improve performance, add features, or fix bugs.
  • Clean Your Lenses: Dust and smudges on the camera lenses can drastically reduce video quality. A quick wipe with a microfiber cloth can make a huge difference.

Rexing M3 vs. M2: What’s the Difference?

If you’re looking at Rexing mirror dash cams, you might be wondering about the Rexing M3 vs M2. It’s like comparing siblings – they share a lot of family traits, but each has its own unique strengths.

Here’s the cool part: RexingUSA actually confirms that the M3 and M2 use the same power cables and rear camera. This means if you’re upgrading from an M2, you might be able to reuse some of your existing wiring, which is a nice convenience.

So, what sets them apart?

  • Channel Count: The most significant difference is that the Rexing M3 is a 3-channel dash cam, meaning it records from the front, cabin, and rear simultaneously. The Rexing M2 is typically a dual-channel system, focusing on front and rear recording. That extra cabin camera on the M3 is a big plus for rideshare drivers or anyone wanting interior monitoring.
  • Screen Size/Design: Both are mirror dash cams with large displays, but the M3 specifically highlights its 12-inch IPS touch screen, which offers a broad, clear view and intuitive touch controls. The M2 also features a large screen, usually around 12 inches as well, and offers similar streaming media and backup camera functionality.
  • Specific Features: While both have essential features like GPS, G-Sensor, loop recording, and parking monitor, the M3 emphasizes its comprehensive 3-channel coverage and the highly adjustable cabin camera with night vision. The M2 also had features like Blind Spot Monitoring BSD and Advanced Driver Assistance Systems ADAS in some variants, which aren’t always explicitly highlighted in the M3’s main feature list, though modern dash cams often share many core functionalities.

In essence, if you need that extra layer of interior surveillance and want the most comprehensive coverage, the Rexing M3 is likely the upgrade you’re looking for, building on the solid foundation of its predecessors with that crucial third camera.
