Are you able to play music on the car speakers from your phone? The process on iPhone seems very awkward (talking to google assistant instead of just selecting a song).
I do it the awkward way too. But I typical play an artist that I loved two decades ago and crank the volume. So "My music" wasn't the best way to describe it. More music that is just for me. I don't find their inbuilt music channels you can play from the center console to be that good. There is lots of UX things that could be done with music that wouldn't be hard.
