catching up on the thread. I wouldn't be too sure about working with a Porsche. I bought the carplay2air to use with my 2018 991.2 and the wife's 2017 Macan. Neither work. The PCM thinks an iPhone is connected and I can see the menu, but on the iPhone I never see a SSID. The PCM never display the SSID name it's using. Unit also doesn't work in my F150, same issue.
carplay2air folks were useless and only said to return it to China. If the unit worked, I would be charged a restocking fee. I would avoid them. Website has a US address, which is just a UPS store mailbox.
