You're right, it's not only not easy, it's almost impossible. There is no way to have AA wireless in the Kona because you need WiFi for that which the Kona doesn't have. https://www.lifewire.com/android-auto-wireless-4176354 That's the reason that there is almost no Android Auto Wireless out there.

Does Apple Car Play work without requiring a USB connection ? I haven't had an iPhone since the IP4 but this sounds like a good reason to reconsider.
CarPlay requires the direct connection. I switched from android to iPhone and I do prefer CarPlay over AA.
