10.2" Rearview mirror monitor + Water Proof Camera + TS
All in one kit. I think this uses the same camera that Neil has, but has a wider monitor that clips on the factory mirror, and is "presumably" reflective enough to double as a mirror when it is off. This has the dual inputs, so you can buy 1 more camera and be set. What you get with 120 degrees of vision depends entirely on camera placement. This seems like a pretty compact solution. (I'm not a salesman for, or have ever had anything to do with whatever company this is.)
