20/20 is stuck on stupid. It likes to override the reported heading all the time. So it shows the combine as being in reverse despite the fact that autosteer works and the GPS signal is accurately reporting the heading. Reacquiring the GPS signal doesn't fix this because the it still overrides the reported heading so it shows the head as empty even if it reads bushels.
Is there a button or setting to fix this? On the planter you can go into advanced swath control and reverse direction.
