Reverse camera install with Car's Gadget components

[Quidproquo]

Has anyone purchased and installed a backup camera upgrade kit from carsgadget.com?
I am considering adding this to my 2013 B8.5 S4's concert stereo, but am not sure if this works as advertised since I see nothing on this forum mentioning or reviewing the kit.

Thanks...

Ours is $350 + $100 and I need an install video so I'd install it for free. All the parts are in stock.
