I have a 2005 F250 FX4 CC lariat 6.0L It seems my compass is not working. When i go to reset it, it says in the display: check compass module, does anyone have a clue as to where this might be or is it something i have to take to the dealership for?

 

Before I paid the dealer to fix it (unless its under warranty) I'd buy me one of the ones that stick on the windshield for a couple of bucks and be done with it.
