On my 20 minute trip to work, my DMH-W4660NEX gives me an error message that (wireless) Android Auto stopped, and it kicks me back out to the home screen. I can always just tap Android Auto and it'll start right back up. What's causing this? I'm sure there are lots of potential issues, anywhere I can check to diagnose? Phone is a Samsung Galaxy S20+. Phone, firmware, and Android Auto are all updated to latest versions.

Have you found out anything about this? 

I have a W8600 with the same issue. 

Pioneer's response to the problem is mostly silence and the blackhole of "send it in for service". Brand new unit.
