I used to have a 310XT that never wanted to upload data to my pc laptop. Now I have a Fenix 2 and am having the same problem w/ Garmin Express. I plugged in the USB cable and it just sits there, searching. I looked at the other recent thread on this issue and the link provided by the mod was the same one I'd seen elsewhere which pertained to other models and just aimed you toward making sure the device was paired. That never did me any good w/ my 310XT and I don't even know how or IF you have to pair w/ the Fenix 2. Any ideas? And I'm on the most recent iMac running the latest OSX version.
