When I talk about the "AA/CP" app, I'm referring to the app that provides Android Auto/CarPlay. It's one of three shortcuts on the EV Play taskbar - the white icon with the green phone - when EV Play turns on. Pressing on this icon brings you to a blue screen that usually says "Connect to Phone" or "Insert Product."
This app also contains numerous settings, which are accessed by pressing the gear icon at the top left corner. Note that you must be disconnected from Android Auto/CarPlay to access these settings.
Here is how they should be set:
Decoding Method: Software
Advanced Settings > Media Delay: 750 (Android Auto only)
Advanced Settings > Audio Channel: Bluetooth (if CarPlay) or Box (if Android Auto)
Advanced Settings > App Full Screen: On
