Important Notes:

• GPS reading vs. vehicle speedometer: The HUD's GPS speed is a reference only. Your vehicle's built-in speedometer remains the calibrated, legal reference for traffic regulations.
  
• GPS coverage: Signal may be temporarily lost in tunnels, underground parking, or between tall buildings - display will resume once the signal is reacquired.
  
• Daytime visibility: Reflective film performance depends on ambient light. For best clarity, install on a clean glass surface and avoid direct sunlight on the unit itself.
  
• Power source: This model does not read OBD data. It only requires 12–24V power; no diagnostic port connection is needed.
