This has got to be the most frustrating thing about Apple Maps & the iPhone. I am driving down the road, and I take a call (using the steering wheel buttons, using bluetooth, or even answering using an AirPod in one ear), the call screen takes over the map, not letting you know where to exit or where the turn is! Is there a way to make it so the call screen doesn't take precedence over the map? They should make the map absolute priority! Now couple this with Face ID to just get the map to come back up up during a call is a driving disaster!
