Error loading waypoints from device

etrex 30 with factory firmware (mar 2012 I believe it was 2.30).

I believe you have a corrupted GPX file and until you fix it or remove it, you will continue having problems.

I have since updated the Etrex 30 firmware to 2.7 and have not had any difficulties yet, but I am not using the device the same way so I do not know if the file corruption problem is fixed.

I have just now extracted and save all my data and am about to do a complete reset on the device, and will take many waypoints per day for several days to see if the problem persists.

Upon reflection I realize that I may have played some part in the corruption of the GPX files:

Being in heavy use for over two weeks, the batteries were naturally being replaced/recharged on an almost daily basis. It was not my intention to capture tracking data and I did not know that tracks were being recorded.

It is quite possible, even likely that during the many battery changes I may have yanked the batteries without powering down or that the batteries ran down. Had I not been recording tracks, that would be immaterial, but since I was, it is just possible that the batteries go yanked while the device was updating a track.

It would be an extraordinary coincidence of events, and indeed, for this recording schema I think there is an onus on the device to recover gracefully so it is still a system software defect.
