Rear view mirror Compass calibration

[rtjeepman]

I have a 2006 LJ. It has a compass built into the rearview mirror and the calibration is off. Does anyone know how to adjust the calibration on this? It's just annoying to not be able to utilize this handy feature.
Thanks in advance.

Thank you. I have googled this issue many times before and never found that link. I will see if this helps me correct the problem on my next day off.
