4. Operating Instructions
Automatic Operation
The M2 HUD features an automatic switch function. It will automatically turn on when your car starts and turn off when your car stops, conserving power and ensuring a seamless user experience.
Display Features
- Speed Display: The primary function is to display your current speed in large, clear KM/H digits.
- GPS + BEIDOU Dual Data: Utilizes both GPS and BEIDOU satellite systems for accurate and reliable speed tracking.
- Automatic Brightness Adjustment: Equipped with a fully automatic light sensor, the HUD adapts its brightness to ambient light conditions. This ensures the display is clear enough during the day and not dazzling at night.
- Integrated Hood: The unit comes with an integrated hood design that covers the lights of the display panel, further reducing glare and ensuring no dazzling when driving at night.
- High-Definition Experience: The front side of the display adopts metal nanotechnology to eliminate unnecessary reflections, making the projected image clearer and sharper.

5. Maintenance
To ensure the longevity and optimal performance of your RYSJM M2 HUD, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry, or slightly damp cloth to clean the exterior of the HUD unit. Avoid using harsh chemicals or abrasive materials, as these can damage the surface.
- Reflective Film: If the reflective film becomes dirty or damaged, gently clean it with a soft cloth and mild glass cleaner. If severely damaged, it can be replaced.
- Storage: When not in use for extended periods, store the HUD in a cool, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
- Incorrect Speed Display: The M2 HUD is a GPS digital speedometer, meaning its speed data is collected from satellites. If you are testing the device indoors or in a parking lot with poor satellite signal, the speed may not be displayed correctly or at all. For accurate readings, conduct tests outside the vehicle in an open area with a clear view of the sky.
- Display Not Turning On/Off Automatically: Ensure the USB cable is securely connected to both the HUD unit and a functioning power source (cigarette lighter or USB port). The automatic switch relies on the car's power supply.
- Display Too Dim/Bright: The HUD features automatic light sensitivity. If the display brightness is not optimal, ensure the light sensor on the unit is not obstructed.
- Display Reflections/Ghosting: Ensure the reflective film is properly installed on a clean, smooth part of the windshield. Adjust the angle of the HUD unit slightly to minimize reflections.
- Device Overheating: While the product is designed for automotive use, prolonged exposure to extreme direct sunlight in a closed vehicle can cause high temperatures. If you notice excessive heat, consider repositioning the device or providing shade.
