It's OK-ish, but two things made it unusable for me. Firstly, the fact that you cannot just lock your route - they will keep trying to "optimize" your route, no matter what. I wish you could turn off this behaviour in settings. Most of the time I select specific routes for a reason and I don't want the app to mess with my selection! Secondly, the black screen issue in Android Auto hasn't been solved for years now. I feel like they're taking a mickey with it by now.
