Plug the rear camera connecting cable into the front unit and run the cable through the roof console, headliner, and straight down the length of the car to the B and C pillars.
Again, don't just run the cable under the rubber seal because it will create a little gap that might prevent the door from sealing properly - you will get wind noise or worse, water can seep into the car. Take your time to guide the cable under the trim - remove the B pillar covers and use the pry tool to carefully tuck the cable underneath the panel covers.
When you get to the rear windshield, route the cable along the rear windshield headliner until you get to the rear camera.
Plug the connecting cable into the rear camera and power on your car to turn on the dash cam. You will hear a Thinkware greeting prompt. If you haven’t done so, download and install the Thinkware Cloud app on your smartphone. Once your dash cam is powered on, press the WiFi button on the front unit to switch it to WiFi mode and then connect to the dash cam using the Thinkware Cloud app on your smartphone.
Use the Live View feature to check the viewing angle of the front and rear cameras and adjust if needed.
