We installed the Green Fit on a Case 8250 to use for autopatch and machine sync.  The problem is we can't get the combine to show the grain cart as a follower.  Tractor is an 8R with a 7500 receiver on SF1 RTK using a Gen5.  The Combine has a 6000 globe on base station RTK with a Gen5 monitor.   The Green fit works for auto trac on guidance lines but we can't get it to link to grain cart for machine sync. Both monitors have the 25-3 software and advance license.  Both units have a MTG with the antenna.  Tractor shows linked to combine but combine shows 0 followers.  Any thoughts on what to check?

Thanks
