marq2 Yes, there is an open pinned issue on GH. Right now for us GrapheneOS users, using Gearslip is the best option for getting an Android Auto experience in the car with Vela. Vela actually inspired the project, and the dev and I have been talking, and there is a big update coming hopefully soon that will improve compatibility with newer cars.
But either way, I am all for poking for ways to make Vela on AA work for others. It already works with stock Android if you use KingInstaller.
I don't personally use AA, so if you want to submit code to make the AA experience more like Gmaps, more functional, prettier, etc, all would be appreciated.
