I have a 2018 Jeep with UConnect 4 (8.4" display). A week or two ago, Android Auto stopped connecting to it on my new Pixel 3. I plug the phone it, and it notifies me that it's charging, but that's it. It has worked before - maybe before the most recent security update.
With this particular head unit, there's no way to start Android Auto without plugging the phone in. (The icon doesn't appear when a phone isn't plugged in.)
Android Auto still works without any issues on my older Nexus 5x (Android Oreo 8.1), with the same head unit and cable.
Any idea how I can fix the problem to get Android Auto working on my Pixel 3? Any idea how I can debug it?
