Help!

My 2009 2500hd 6.6 LMM won't crank. Somehow it got put in compass calibration mode and won't exit out of it. Lost on what to do. Everything is reading at 0. I can't drive in circles because it won't start but everything works..lights, key fob, battery is good. Everything was good until this calibration mode stuff got pressed.

Remove both negative cables on the engine compartment batteries for about 10 minutes. Then re-attach and see if any difference. Kind of like re-booting your computer for comparison.

Moved to LMM section.
