Is the Z4 you just bought also a 2011? This may help answer your question about whether wiring for a backup camera is in place. I have my doubts on a 2011 but I have no definitive facts one way or the other.
PS-I've also seen wireless backup cameras that bluetooth to your phone but have no direct experience with one.
