I think since Android Auto compatibility requires proprietary Google binaries embedded in the apk, the degoogled version distributed on f-droid (as per f-droid’s terms) isn’t compatible. There’s a “full version” distributed in the github releases if you’re okay with those being included.
You can keep apps from github updated using Obtainium if you like.
You might still want to double check its the right version as the degoogled version is also distributed in the github releases alongside the “full” version.
If the package name is `com.eddyizm.degoogled.tempus" it’s the wrong one and won’t be compatible with android auto
