3. Setup and Installation
Follow these steps for proper installation of your dash cam:
- Prepare the Windshield: Clean the selected area on your car's windshield thoroughly with the provided cleaning wipes and lint-free cloth. Ensure it is dry and free of dust.
- Apply Electrostatic Film: Peel off the protective layer of the electrostatic film and apply it to the cleaned area of the windshield. This prevents adhesive residue on your glass and allows for easier removal.
- Mount the Front Dash Cam: Peel off the 3M adhesive tape from the front camera bracket. Firmly attach the adhesive mount onto the electrostatic film, ensuring the camera's field of view is not obstructed. Adjust the camera angle as needed.
- Connect Power: Insert the USB-C power cable into the dash cam's GPS mount and route the cable along the windshield edge, down the A-pillar, and to the passenger side floor mat. Use the pry tool to tuck the cable neatly under the trim. Insert the car charger into your vehicle's cigarette lighter socket.
- Install Rear Camera (Optional): Peel off the 3M adhesive from the rear camera mount. Attach the rear camera to the rear windshield, ensuring a clear view. Route the rear camera cable along the ceiling and side panels to connect to the main dash cam unit.
- Power On: Start your vehicle. The dash cam will automatically power on and begin recording.
