The rear cam is Joying's rear cam that I ordered with the head unit this past spring. There is a slight delay of approx 2s switching from rear to front to user-interface, but all in all it works well and I like it for parking and pulling into tight spots. Joying has a nice feat that you can set the front vid as front 'Cam' and then when reversing you get backup cam and when leaving reverse you get about 5s of front cam automatically. You can then access the front cam on Joying screen anytime using their camera app (1 press action). Like I also accessed and went through the grommet from under the car - no hood removal necessary for any of this install. It comes with a long enough cable to reach all the way through the main front tub grommet to plug into vid in of the joying head unit.
