I joined this campaign on indiegogo, which tries to provide an aftermarket solution to wireless AA: AAWireless
The problem is that they have had some delays... Currently the estimation for delivery is March 2021.
I'm hoping that this will work, especially since my Corsa-e provides wireless phone charging. It would be really nice to just drop my phone and get wireless charging and Android Auto, without the hassle of any cables.
But time will tell. I'll keep you guys updated when I receive it (hopefully).
