Running a ez guide 500 with ez steer and have been having trouble with it wanting to wonder all over the place. Tried recalibrating,a hard reboot and it still wonders. When it is running it will start to get off line a couple of inches so it starts to adjust but it will over correct and then try to adjust really hard the other way and if you let it go it would actually turn the tractor around. It was running good this weekend but now can't get it to work. Tried our local dealer and all he said was to recalibrate and if that don't work reboot it. Running on waas and have the current software and firmware updates, have good sats. Anyone had this problem?
