- Position the HUD: Place the non-slip mat on your dashboard in a position that allows for clear projection onto the windshield without obstructing your view of the road.
- Route the Cable: Carefully route the connecting cable (OBD or USB) along the dashboard and tuck it into the A-pillar seal or other trim to keep it tidy and secure, preventing interference with driving controls.
- Apply Reflective Film (Optional): If the projection on your windshield appears blurry or has a double image, apply the reflective film to the windshield directly above the HUD unit. Clean the windshield thoroughly before application.
- Power On: The HUD will automatically power on when your vehicle starts.
