Installation: Please test functionality before installation: connect the car charger, attach the rear camera, insert the SD card, and confirm the dash cam works properly. Step 1: Please install the dash cam in the middle of the windshield to facilitate DMS detection. Clean the mounting area on the front windshield. Apply the mounting sticker and remove bubbles. Let it sit for 30 minutes before attaching the 3M mount, then wait 12 hours before installing the dash cam for better stability. Step 2: Route the power cable along the windshield and roof with the included tool, hiding cables in gaps to avoid blocking vision. Step 3: Rear camera installation: Clean the interior rear windshield, apply the static sticker and remove bubbles. Attach the rear camera with the provided 3M adhesive to the prepared position.
