Ram guys that like electronic toys -UPDATED!

Why on earth do these systems have to be hacked to get those features!? Obviously TV, music vids, etc are not a great idea, but this is the essential first step to implementing a rear view camera on your trailer. I would like to have a split screen for both video inputs, one on each rear corner of my trailer. If/when I finally get a new tow vehicle, something like this will be very high on my to do list.
