Hi,
I own two devices. Garmin 510 for cycling activities, works fine with Garmin express.
Forerunner 305 has problems.
Other times writes sync errors
Other time sync successfully , however I don't see any new (untitled) activities in Garmin Connect.
I tried to completely uninstall Garmin express, including cache and library objects. Then I downloaded and installed again.
Again same problems, no luck
Any ideas?
Note>the same device FR305 syncs fine with Garmin Express for Windows. So, I believe that the MAC version has issues.
