My nav is out and my check sa awd is on my dash display but i dont feel any problem

 

Ok sorry does anyone have an idea about how to fix nav that doesnt intail pulling dvd and sending in to alpine and any idea what i should be looking for that migyt ne an issue with awd system

 

More details please. Did both these issues appear at the same time? Do you suspect they are related or are they totally separate. I doubt they are related. I would eject the nav disc and make sure it's clean and no scratches. Then try again. But it's also common for the nav units to go bad, requiring a repair.
