Android Auto has always been a little funky.
I used it with my 2015 Accord just before turning it in and now with my 2018 Accord.
First with my 6P and now with my 2xl (waiting on my 3xl next week).
Every once in a while it disconnects randomly or some other flaky thing, but it's rare.
Before a long trip I'll reboot my phone and I never have a problem.
Again, it's rare and it is one of my favorite phone related things.
I love the hands free aspect of navigation, phone calls, text messaging and on a recent trip I actually streamed play music as I was in my wifes CRV that doesn't have xm and finding radio stations as you go state to state is an effing hassle.
Also use mlb at bat over android auto. Very cool stuff.
