I had a guy tell me this could be done.  Any one comfirm this or have done this?  Running a CFX 750 in the planter tractor and running a AFS 600 in combine.  Is there a cable that can be run between the two monitors to tie them together?  If so, what all can be done between the two?  Can we do a variety locator type feature since we planted with the CFX and marked varieties?  And if so do you know what cable I'd need to do this and install instructions?
