Hello,
I have a FR110. I think it has done a good job on elevation, but today it didn't do too good :)
I uploaded the file to garmin connect, but I had two elevation spikes. I exported the file as .gpx and manually entered the correct height for the two spikes. I deleted the old activity, and imported the file. It imported fine, but the spikes were still there. I then try to export as .gpx again (the activity that I had manipulated), and the elevation spikes were back in the file again...
How did garmin connect now that the spikes were there in the first place, when I have manually removed them from the file?
My theory was that the activity was never actually deleted, just removed from my list. So I tried using a different file name, but that didn't help. I also tried to change the start time, but no luck there either.
I have tried searching the forums. Most advice is pointed at calibration.
