I am looking to install 4 cameras to my 2018 JKU (F,B,L,R)… and would like to be able to record video from each. Most all mobile DVR's come with a separate monitor. I would like to instead have this displayed and accessible through a head unit, with the ability to switch from one camera view to the next. Surely this has been done, but I have been unable to actually locate anywhere online where it has. Simply put, id like to use the head unit as a monitor, possibly by using an AUX Video input. Can someone point me in the right direction as to what head unit (or dvr for that matter) to purchase? I can care less about sound as I am not an audiophile. I have looked at the seicane android unit and it seems good, but surely there are other options.
