Thank you for all your help. After everything, it turns out that the solution lurked in a settings menu in sandboxes google play services.
For anyone else reading this who also doesn't read the fine print, go to settings, apps, sandboxes google play services, android auto, and toggle on USB access permission and audio permission.

Thank you, this is very actionable. I will try all of these once back in the car.
For clarity, it is the wire connection specifically that doesn't work. I can play audio over BT, but obviously, overusing wireless defeats the purpose of GOS.

Out of curiosity, what permissions do you grant AA? I only enable notifications and (since this thread) microphone.

I appreciate you taking a look for me. I did try the recommendations in that thread as well as several others. From what I've seen, this is a general connection/incompatibility/security error, but this only means that identifying the actual cause will be more difficult.

Certainly. The error reads as follows:

"The time on your vehicle system does not match the time on your android phone. Please move your vehicle to a location where it can receive GPS signal so the clock is set automatically"

It's worth noting that the clock has indeed been set automatically. Googling shows other people with this error both on GOS and stock Android, but I can't find a solution.

When the issue began, I tried uninstalling and reinstalling AA on my pixel 7a. After reinstall, AA simply doesn't connect to my toyota head unit. The car keeps popping up with a warning saying the time on the device does not match. Anyone know about this?
