Is there anyway to get the Nav Display to stay on the Radio instead of automatically switching back to the map or Menu? When I'm not using the map I would rather have it stay on the Sat screen to see the song title information.

 

Old post, but just in case anyone else encounters the same problem the setting is located at:
Menu -> Setup -> General -> Auto Screen Change

If this setting is set to 'Off' the screen will never switch back to the navigation screen automatically -- you'll have to press the Map/Voice button.
