I highly recommend you contact Patryk at Bimmertech. He sells a complete OEM kit and also other retrofit options.
oem solution requires PDC (Bumper sensors). Parts needed are as follows
New trunk handle and camera
camera module and bracket
wire harness for camera module (includes power wires, canbus wires and video signal to headunit)
HSD cable for camera to module.
once this is installed, you need to do VO coding to activate the option.
