Today I did most of the install of the FieldLevell II stuff on my tractor.  The tractor has our disc on it right now so I didn't move the GPS receiver from the roof yet but I have a calibration question.  I went into the calibration section and pressed start and it just stays at zero.  There are no errors.  If I go to diagnostics and press the up or down button it does accuate the hydraulic on remote number one.  Does the FMX have to have a GPS fix and sense the receiver moving for the calibration process to work?
