Installation

Step 1. Install the RoadMate CPDuo

1.1 Prepare the Mounting Position:

Clean the dashboard or windshield: Ensure the area where you'll mount the camera is clean and free from dirt, oil, or debris. Use a mild cleaner to wipe the surface and dry it thoroughly.

1.2 Mount the Camera:

Positioning: Align the camera to get the desired angle and view of the rear. Rear dash cams come with adhesive mounts or brackets for attachment.

Secure: Use the adhesive or mounting bracket to securely attach the camera to the chosen spot. Ensure it's firmly fixed to avoid any movement or displacement.

Step 2. Install the Memory Card

The Rexing RoadMate CPDuo accepts Class 10/UHS-3 or higher Micro SD memory cards up to 256GB. You will need to insert a memory card before begin recording.
