I really did not like the radio/camera system that came with the rig and when the rear camera went out I replaced it with a
Kenwood DDX9707S and paid my local installer to set it up. It has Appleplay as well as the Android play system. I use the rear view camera to check on the guy following me so close in the Jeep but to get a constant look at the Jeep I use a Bluetooth dash camera and one of my Iphones that I replace with new to run a constant feed. That camera is in the back window and the phone is on the dash.
The first time we towed the Jeep my wife was talking with one of our daughters who was asking how the trip was going and she said "fine but some AH in a Jeep is right on our tail and won't back off" That cracked us all up.
