Rear crossing warning

Is it possible to code the rear crossing warning? What physical equipment do I need?

BMW's cross traffic alert is not very good. Save your money.

If I haven't got what I require I won't pay for it, just wondered if I can code it? I already have rear camera and sensors, but don't know if I have everything needed? There are at least 4 sensors on my rear bumper.

I know there are 2 different versions of the PMA ECU. A high and a low version. The LOW version is for vehicles with PDC and the HIGH version has another connection point for the 4 additional PDC side sensors(for cars with parking assistance package). I'm not sure if the HIGH version also includes additional logic to allow for emergency braking.

We also have a 2020 X3 and the emergency braking feature always activates while backing out of the driveway. It's a little too sensative.

I seem to have parking assistance, but don't think I have the parking assistant professional? So not sure...The car will find a space and park itself. What's the code I need on my FA?
I also have something in the iDrive called Emergency Braking. I don't think it's the same as Rear Crossing Warning, think it's just for parking? Certainly the other day I was backing out of somewhere where my view from the drivers seat was blocked by a bush and I nearly hit a police car that was going past. Well that's an exaggeration, I was going slow and saw it in time to slam my brakes on...but no warning from the car.
