Check out the Vakry wireless system. Very inexpensive on Amazon. Easy camera install using 12v clearance light wiring, or entry point if you’re so equipped. HD video is great on dash mounted monitor. I installed this on my Micro Mini last month. Works great, but does require you to have your lights on while driving.
