The rear view system that I bought has spots to hook up two more cameras. I think a nice addition would be a couple of side monitors aimed at my blind spots that are always on the split screen. I normally try to know exactly what is in front, behind and on both sides at all times when I'm driving, where they would really come in handy is maneuvering through congested traffic when I have to merge left or right to stay on my designated route.
