Android auto is, to put it lightly, shit. The compatibility issues itself are enough to make one vomit (try finding out what’s required to use wireless connection) but once you manage to connect it it just gets worse and worse. I would not put it on my main phone even if it did work. Instead I bough cheap stock android phone and got a cheap, data only SIM (€2/month). The phone stays in my car, is not used for anything else and doesn’t have any personal accounts. I’m fairly happy with this setup.

You can say what you want, but using a phone instead of the integrated dashboard of your car is not a better experience. I kinda like android auto. My stupid car didnt support android auto wireless (only cable), but I bought a device that acts as a bridge. So now my phone automatically connects to Android auto and it just works every time. I can open my calendar on my dashboard and navigate to the addresses of my appointments with one click.
