A few weeks ago I purchased a vivofit so I was required to update my Garmin software to Garmin Express to support the vivofit. I was able to pair both the vivofit and the 910 without problems but I have had no luck with consistently being able to sync the 910. Usually what happens is that it will say it is "preparing for transfer" but then I get an error message that the device wasn't found. On the 910, I can see the signal on the top right corner that I believe means it is trying to transfer the data but it won't work. This morning I tried at least 4 times before having to give up and get ready for work. So frustrating! My usual fix is to reinstall Garmin Express. I did that tonight (after a couple of more failed attempts) and I finally got this morning's run to upload on my second attempt.
Before changing to Garmin Express, all I would have to do is walk in from a run, get near my computer and "beep" my Garmin was automatically transferring the data. This is so frustrating to have this problem so I would appreciate any suggestions! I have had problems with it not finding the vivofit as well but I can sync that easily with my iPhone so that isn't an issue.
Garmin Express tells me that my 910 is running Version 3.0 and is current. My Mac is a MacBook Pro running OS X 10.9.5.
Thanks so much!!
