We pulled into the field and the yield monitor is working in all respects (auto section, yield, moisture, etc.) except that on the map window it is not mapping. I think it is logging data and when I pull out where I've already been the thing knows it. But it won't show the yield map on the screen. It's probably something simple stupid but I'm stumped. Tried the obvious stuff (turning on and off, yelling, swearing off all new tech) but now I'm wondering if anyone else has this problem?
