A little background:

2012 DB60 hooked to Case450 Row Crop Quad.  JD2630 monitor in cab hooked through a seperate ISO plug to control planter.  When I fire up the tractor all units of measure are in US. except for the planter (ha, cm etc...)  If I go to the display tab and go to units of measure and switch from US to Metric then back to US the units change to US on the planter.  I lose this everytime I shut off the key.  Any suggestions?
