It's been about 3 weeks since my compass stopped working correctly, and instead just shows "--" where "N" or "S" etc should be. I tried holding 7 & 9 together on the radio buttons, to re-calibrate, but that didn't work. Also unhooked the battery to see if it would reset something, but that didn't help. The compass in my 2010 GT is on the lefthand side of the digital radio display. I never use the compass, but that fact that it just doesn't work now is frustrating me... Anybody have any idea on what I can troubleshoot or try to fix?
