Great post & thanks for all the details!!!
Below is the link which says wireless backup camera. Like to have your opinion on using this.
Wireless CCD Car Rear View Camera for BMW 1 3 5 7 Series x3 x5 x6 Z4 E39 E53 E46 | eBay
If i use the above can i pass the cables through the existing square hole? by replacing the left side reverse light?
I have attached 3 photos showing plastic weld. Please confirm i have to cut them.
Many thanks
