I personally find all the open source Open Street Maps based apps to be extremely lacking. 90% of the places I'd try to find aren't there and for some. of them navigation was off too. I use Here We Go.
Good: No missing locations. Uses Trip Advisor for reviews. Database & navigation is good. Less features than Google but low bs. Privacy policy states that no personal user data is collected without consent, and is pretty short & sweet. Telemetry is opt in, though you can't get traffic data without it. There is a toggle to run it entirely offline. There are buttons to delete history or delete all data collection taken. Based in the Netherlands. Owned mostly by German car manufacturers.
Bad: No search along route or Voice Assistant in Android Auto. Closed source. 2 trackers (Facebook login, Google Crashlytics, both optional though). Rarely any pictures. Requires you to download from the Play Store to use in Android Auto (no Aurora).
