Park Distance Control aftermarket options?

I just purchased a '16 M235i Xdrive, which is on it's way over to the United States and should arrive at the dock next week. The one package I kind of regret not getting is the Driver Assistance Package with the rearview camera and Park Distance Control features.

I saw on here that Bimmer-Tech.net offers a rearview camera option. Are there any options for Park Distance Control?
