So I just bought a used '03 G35 Sedan and not six hours (i wish i were exagerrating) after taking it home, the navigation system starts constantly showing a "Door Open" warning. The door sensor on the dashboard wasn't lit and I went around and firmly closed each door three more times, and it still says door open. It always kicks in when the car starts moving, when it stops, it goes to the default screen. Not off to a good start here. Since it is a used '03, it is not under warranty. Anything I can do?

 

close the trunk..........

 

I'm not sure how it is setup in the g's, but it might be talking about the door on the player, if there is one.
