I have been looking for information and/or any advice on installing aftermarket
rear parking sensors on my 2013 Convertible.

I came across a system out of the UK from Parking Dynamics

Assuming it actually functions as described, it looks like one of the nicest possibilities out there.

Has anyone installed this, or know anyone who has, perhaps on another non-Mini vehicle?

I am pretty sure I going to give this a try, at the cost involved, it looks like a good possibility.

I could also use some pointers on removing the rear bumper as well….
