4.2 Mounting the Main Unit
- Clean the area on your windshield where you intend to mount the dash cam.
- Apply one of the provided electrostatic films to the cleaned area. This protects your windshield and allows for easier removal.
- Peel off the protective film from the adhesive mount pad on the main unit.
