For me to fully drop google someone needs to create something compatible with Android Auto in my car, it doesn't sound like a big deal but that's a big enough thing for me to need it now.
Pretty much, my car doesn't have navigation built in but supports android auto. I've tried a phone mount before but the experience is so much worse when it's not integrated with the car (volume of announcements and music can't be done independently, can't switch what music/podcast app's playing without grabbing my phone, etc) that I just went back to using it.
Is there an open-source alternative to Android Auto? It cannot be a regular tablet app, its UI has to be adapted to car driving (bigger buttons and simplified UI, at a minimum) and it should make use of the car ECU data.
