Parking Sensors / Cam Retrofit

[bspaulsen]

As my carbon parts start to roll in, I'm looking to retrofit some parking protection that didn't come with my 2017 F80. As for options, I'm only aware of Bimmertech's PDC option, their front + rear camera + MMI kit, and a slew of other cheaper ultrasonic sensor kits on Amazon.

Do any of y'all have any experience with either of the Bimmertech kits?
Installed any of them before?
Do you prefer front/back PDC over dual cameras or vice versa?
Does PDC do a good job of picking up parking blocks/curbs/objects that a lip may impact?
