Wireless AA is currently in the works through an add-on kit and seems to be progressing well. I don't know the status of it with CP.

The kit is out (if you're talking about the proper OE retrofit kit) and sadly no you arent going to easily put the 2021 radio into an older car. The wiring is missing, heck the entire bus is missing, the correct cluster is missing, the correct onstar module is missing etc. We did one for a company in Russia and had to custom program a few modules and they had to basically rewire the entire infotainment. I want to say around $5K job and it was still hacked together.
