Help I am trying to decide between the f90BT and the DNX8120 I was told that the 8120 can do dual zone I can play a movie in the back and listen to my music in the front..

 

Can the F90BT do that, Also Can I do NAV in front and movie in back at same time also??

It is not dual zone, so you can't play a movie and listen to something else.

You can use the nav and play a movie at the same time though. The audio from the movie would be the only thing you could listen to though
