Some owners have managed to get AA working by using a third party adapter. These adapters basically connect to the car as if they were iPhones using the carplay protocol. I'm not sure whether it's a true AA interface or just screen mirroring, though

It's true AA and as you explained, the way it works is by making the car believe it's running apple carplay.

Could you indicate which adapter could be used?
I see several adapters to make a wireless connection to replace a wired connection, but a change in protocol (AA to CarPlay) i don't find.

Mine works with this adapter https://www.aliexpress.us/item/3256806281206441.html
