Unlike in most sedans, mounting the rear camera in a vehicle with a rear liftgate does require a few extra steps, and the best way to run the cable is to go through the hoses between the chassis and liftgate. If there is any trim on the liftgate, it's best to remove them to hide the rear camera cable under it.
Typically, there are 1 or 2 hoses that connect to the liftgate, and it's best to give them a squeeze to check which one has more wiggle room before attempting to run the wire.
Tips and tricks? You can use a long zip tie, a coat hanger, or any variation of a long wire to guide the front-to-rear cable through the headliner and the rear hatch grommet before connecting to the rear camera.
Plug the connecting cable into the 2K UHD rear camera and power your car to turn on the U1000. You will hear a Thinkware greeting prompt. Suppose you haven't done so, download and install the Thinkware Cloud app on your smartphone. Once your U1000 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 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.
