Introduction
The Riloer Universal Car HUD Display Phone Holder is designed to enhance driving safety by projecting navigation information from your smartphone onto a transparent panel. This allows drivers to view directions without diverting their gaze from the road, improving focus on traffic conditions. The device utilizes hardened organic glass to prevent scratches and optical reflection principles for clear display.

Setup
Follow these steps to set up your Riloer HUD Display Phone Holder:
- Choose a Location: Select a flat, stable area on your car's dashboard that does not obstruct your view of the road or interfere with airbags.
- Clean the Surface: Ensure the chosen dashboard surface is clean and dry. Use the provided cleaning cloth if necessary.
- Place the Non-slip Mat: Position the non-slip mat on the cleaned dashboard surface.
- Position the HUD Holder: Place the Riloer HUD holder onto the non-slip mat. The mat will help secure the device.
- Adjust the Reflective Panel: Open the reflective organic glass panel and adjust it to an angle that provides a clear reflection of your phone screen. A common viewing angle is approximately 45 degrees.
- Apply Reflective Film (Optional): If your smartphone screen's reflection is not clear enough, you may apply the transparent reflective film directly onto your phone's screen. Ensure the screen is clean before application.
- Place Your Smartphone: Securely place your smartphone onto the holder's base. Ensure it is stable and centered for optimal reflection.

Operating Instructions

- Adjust Phone Orientation: For optimal display, ensure your phone's screen is oriented horizontally (landscape mode) and the navigation display is set to reflect or mirror mode if available in your app settings. This will ensure the projected image is correctly oriented.
