Has anyone seen any detailed info about Sync 4 or the 12" Screen. I would love to see the 12" screen have the ability to use various screen setups instead of just single use. For example If you are using Android auto for Waze or Google maps have that on one window of the screen but then have the radio display on another. I guess it would be like having the home screen layout of just Sync but with more functionality

 

My understanding is that that is one of the major improvements. AA / CarPlay only take a section of the screen and don’t gobble the whole thing.
