Pick up the rear camera connecting cable you have routed along the headliner with the power cable and run it along the A, B, and C pillars. Remember, don’t just tuck 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.
Suppose you haven't done so, download and install the FineVu app on your smartphone. Once your FineVu is powered on, press the WiFi button on the front unit to switch it to Wi-Fi mode and then connect to the dash cam using the app. Installation Angle Guide in the FineVu mobile app to check the angle of the front and rear cameras and adjust as needed.
And there you have it, a FineVu GX33 dashcam and Cellink NEO battery pack installed in a 2012 BMW M3. The installation took around 2 hours, including routing the cables, testing the battery pack power source, and checking the front and back cameras using the mobile app viewer.
From the outside, looking in from the front of the vehicle, the GX33 front-facing camera and external GPS module blend in well with the car.
