I know there are many posts about this, but few solutions seem to work. I recent transitioned from a Pixel 7 to a Pixel 9 Pro. On the 7 AA worked fine. The 9 not so much.
Running e/os 3.1.4-a15-20250917526795-community-caiman on Pixel 9 Pro
I tried installing as per the official instructions no go
I tried the stub apps, same error
I tried side loading AA as a system app, same error
Help 
It was working with e/OS 3.2 with Android 14. Now I upgraded to Android 15 and itās broken.
Looks like we will have to wait for it to be fixed. For the FP6 they mention a fix being pushed out to the next version.
Just bought a FP5 and installed /e/OS on my own.
I was so stupid to think it would easily work with my car.
But forgotten how bad Google can be.
i can only pray and beg murena will soon bring out a update which makes Android Auto work in A15.
I cross my fingers for all holen also.
Took a look in the development anouncements.
Android Auto seams to come tin the end of November!
So you can use your de-googled phone when ādriving home for Christmasā! 
Many thanks to the engineers and contributors.
