We have 3 of these gps heads and one of them seems to be no longer able to record data. While the gps is on and operational you can use it normally and any save data can be retrieved, however if you bring up an old field and add more data to it, or even start a new field, the next time you start up the unit those fields are now corrupt and contain no data. On the load screen the acres will show as the exact same amount as all of the corrupt ones below it. as soon as you find a field farther down that shows a different acre amount that is the first uncorrupted file.
These machines are no longer supported, so I was wondering if NAT had some insight.
I have reset this gps to the newest firmware and I have tried to go back a few firmwares to see if it is just a bug in the newest firmware, i have had no luck
