After 3 days of struggles, I finally got the rear view camera installed! After trying to figure out why the RCA wouldn't work, turns out that the actual port on the head unit was faulty! Crutchfield is express shipping me a new one (Awesome customer service, that site) so hopefully it'll be a quick swap!
WOOOOOOOOOOOOOOOOOOOOOOOOOOOOHOOOOOOOOOOOOOOOOOOOOOOOO!
Cool! But that's one of the benefits you had better get by paying MSRP.
I realized that I drove my daily driver 750 miles over the last 3 months. I drove the 4Runner (my foul-weather car) 1500 miles over the same timeframe. I really need to ditch the stock head unit & upgrade. Maybe I will call Crutchfield.
