That needs to be updated !!!!!!! (new version is 5.12)

Note: I had troubles with my 500 Ez-guide unit, with planter row clutches and didn't realize I needed an update done to my "new-to-me" 500 unit(came with used JD8410 tractor) ( = I was stealing the GPS signal from the "new-to-me" 500 unit/tractor and entering it into my Ag Leader Integra, to operate row clutches.)

I only had 2-3 acres left to plant, of soybeans, when I finally got the new software updated, into the 500 unit; thus I don't honestly know if it fixed my problem. (My scenario was at one end of the field, the row shutoffs seem to be fine, but at other end, it was off by as much as 4 feet.) Note: previous years had been close to perfect, with using ALL Ag Leader equipment [Integra and 1600 receiver on JD4440]

 Knowing this was unacceptable(during planting for 2019), I shutoff "AutoSwath" and just planted corn and soybeans the old fashion way, using "Stop and Drop" method and "Stop and Raise" method.
