So I just moved to Arizona from Oregon and when I get here I changed the compass to the appropriate zone but the compass still displayed incorrectly. I did the recalibration of the compass and that seemed to fix the compass...but I have noticed it is messed up again. Sometimes the compass displays the wrong direction and other times the compass display won't change at all (it will just stay on the same direction no matter how much I turn). Any ideas????
