- Attach Camera:
- For cameras with adhesive tape (e.g., Figure 2), peel off the protective backing and firmly press the camera onto the desired surface.
- For cameras requiring screws (e.g., Figure 2), mark the screw positions, drill pilot holes if necessary, and secure the camera with the provided screws.
- Route Cables: Carefully route the camera cables to the main dash cam unit. Ensure cables are tucked away neatly and do not interfere with vehicle operation or safety features. Avoid sharp edges or areas with high heat.
- Connect to Main Unit: Plug the camera cables into the corresponding ports on your T66/T88/T99/T3/ZW3 dash cam unit. Refer to your main dash cam manual for specific port locations.

3.2 GPS Antenna Installation
- Choose Location: Mount the GPS antenna on the dashboard or windshield, ensuring it has a clear view of the sky for optimal signal reception. Avoid placing it under metal objects or near other electronic devices that might cause interference.
- Attach Antenna: Use the adhesive backing on the GPS antenna (e.g., Figure 6) to secure it in place.
- Route Cable: Route the GPS antenna cable to the main dash cam unit, ensuring it is neatly hidden and does not obstruct vision or controls.
- Connect to Main Unit: Plug the GPS antenna cable into the dedicated GPS port on your dash cam.

3.3 Center Console Base Installation

These accessories function as input devices for your main Android rearview mirror dash cam. Once properly installed and connected, their operation is managed through the main dash cam unit's interface.

- GPS Functionality: The GPS antenna provides location data to the dash cam, enabling features like GPS tracking, speed display, and route logging. Ensure the GPS function is enabled in your dash cam's settings.
