Just a quick note: if you're on Android, the only versions that work with Android Auto are OsmAnd+/Maps+; the Free version can use Android Auto to, provided you have activated a Pro subscription.
OsmAnd~ from F-Droid, hoewever, will NOT work with AA: actually it's AA's "fault", since it only recognizes the signatures from Play Store and the app from F-Droid is therefore unauthorized to run.
I remember that, long time ago, there was some kind of trick to make it run, involving changing the app signature, not sure if that would still work today.
