Setup and Installation
The Tefola Car HUD Head Up Projector is designed for non-destructive, plug-and-play installation. Follow these steps to set up your device:

- Position HUD: Place the HUD unit on your dashboard in a suitable position where the projected display is clearly visible on the windshield without obstructing your view of the road. Ensure the unit is stable and does not slide during driving.
- Apply Reflective Film (Optional): For optimal clarity, especially in bright conditions, apply the included reflective film to the windshield where the HUD projects. Clean the windshield surface thoroughly before application.
