As a followup, my car has 6NF - Smartphone integration, check with dealer to see if the 6NF base plate has the wiring for video and they said yes. So I ordered 6NR retrofit software only from Bimmertech and bought a Media snap-in adapter.
After Bimmertech installed the software, it turns out the 6NF is NOT wired for video feed to the CIC. So I have all the BMW Apps functionality except no video feed, which also means Plug-In doesn't work because you can't see.
I am ordering the video cable from Bimmertech to add the wire from the base plate. It is backordered however.

Lessons learned, trust Bimmertech when they say you will need the wire from the base plate, even if you have 6NF, and you don't want to change the USB/AUX to USB/Video (i.e. only have the video through the snap in adapter).

Another big lesson learned, don't forget to add BMW Apps when ordering, hardware is involved and it is not just a software coding exercise. It is also an expensive retrofit.
