Applying Reflective Film (Optional):

For enhanced clarity of the projected display, you may apply the included reflective film to your windshield. This step is optional but recommended for optimal viewing.

3. Apply Film: Carefully apply the reflective film to the cleaned projection area on your windshield.
4. Remove Second Layer: Tear off the remaining No.1 protective film completely. The film will automatically adhere.
5. Exhaust Air: Use a soft cloth or squeegee to gently push out any trapped air bubbles from under the film.
6. Final Peel: Tear off the No.2 protective film. Your reflective film application is complete.

5. Operation

Power On and Satellite Acquisition:

Once connected to a 5V power source, the HUD will power on. The satellite icon on the display will initially flash. This indicates the device is searching for a GPS signal. Wait for the icon to stop flashing and become solid before relying on the speed and compass readings. If the icon continues to flash, move your vehicle to an open area to improve signal reception.

Display Modes and Settings:

The HUD displays real-time speed and compass direction. Specific settings for speed unit (MPH/Km/H), alarm thresholds, and manual brightness adjustment can be accessed through the device's control buttons (Set, Minus, Plus). Refer to the detailed instructions in the included English manual for specific steps on navigating the setting menu.

6. Maintenance

To ensure the longevity and optimal performance of your MAIMEIMI M1-White HUD, follow these general maintenance guidelines:

• Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods when not in use.
• Ensure the power supply does not exceed 5V to prevent damage to the unit.

7. Troubleshooting

Speed Display Inaccuracy / Manual Speed Correction:

If you notice a discrepancy between the HUD's speed display and your vehicle's speedometer, you can perform a manual speed correction:

1. Initial Check: Ensure the satellite icon on the HUD is solid and not blinking, indicating a stable GPS signal. If it's blinking, move to an open area.
2. Confirm Speed Unit: Enter setting mode 5 (refer to the full manual for navigation) to confirm your desired speed unit (MPH or Km/H) is selected.
3. Speed Fine-Tuning: Enter setting mode 1. You will see an initial value (e.g., 107). If your car's meter reads 100 MPH and the HUD reads 105 MPH (5 MPH faster), you need to adjust the HUD's reading down by 5. Subtract 5 from the initial value (107 - 5 = 102). Set the new value to 102. This adjustment compensates for the difference.
4. Factory Reset (if needed): If the speed reading remains inaccurate after adjustment, enter setting mode 6 to restore factory settings. Then, repeat the speed correction steps.

Other Troubleshooting Tips:

• No Signal / Satellite Icon Blinking: If the satellite icon continues to blink, move your vehicle to an open road or area with clear sky visibility to help the device acquire a GPS signal.
• Interference: The presence of other GPS devices in your vehicle may interfere with the HUD's signal acquisition. Try operating the HUD without other GPS devices active to diagnose.
• Power Issues: Ensure the HUD is connected to a stable 5V power source. Using a voltage higher than 5V can damage the device.
