I’m wondering something about android auto.

With iPhone auto, your car stereo can only do that one thing, whatever app is up on the screen with iPhone auto. For example if I am running the iPhone maps application with iPhone auto then I can’t play music from another source such as Bluetooth. Either I’m on the car’s Bluetooth audio screen, or I’m on the Apple screen. I can’t do both. I can’t have the screen of one and the audio of the other.

If android auto was the same way, then that would negate the usefulness of having the app run on android auto.
