It's definitely in the center.
I'm loving my new Z... I now like almost everything about it. But yeah, the backup camera I miss... unfortunately it made me so lazy... I could just glance at the screen and know nothing was behind me and go. Well, that doesn't work now. Forgot to look last night and almost backed into someone!
Here's a pic of the backup camera on my G37. I'm sure it should be placed similarly on the Z.
