Quick question for a nav system guru. When I'm using the nav system and receive a phone call, as soon as I accept the call the display automatically returns to the map and nav voice prompts continue. But when I'm using the nav system and make an outbound call, the phone screen stays active and the display doesn't automatically return to navigation while I'm hands-off talking. I'm assuming there must be a preference to allow an automatic return to the navigation screen once the phone connection has been made but haven't been able to find that addressed in this 2018 owner's book.

Any help, please?
