Here is the mirror I was considering using after I read about CDan adding it:
Rear Camera Display Mirror by Gentex
But I like the Audiovox one better. I like being able to have dual inputs. The only thing I wish the Audiovox had was compass and temp. My wife said she is open to me adding this as long as it has those two things. Our S4 has it and she is hooked.
BRIAN, what was the need for using two rear cameras? Especially given the wide angle view? And also why did you decide to not mount up front?
