I have some sound that plays during a phone call on my app. Its hard to test this on the desktop head unit but i'd like to know on a real device if i simply plug the phone into the car will my audio automatically play to the car speakers ? I notice when i use the DHU that it already sets the phone on speaker so im assuming it routes to the cars speakers but i wanted to make sure.
So to be clear, imagine i have an app that plays music based on some trigger, if i plug the phone into the car and execute that trigger will the audio get routed to the speakers of the car without the app needing to do anything ?
