I had everything working with my new Garmin Forefunner 910XT. After yesterdays run, it automatically transferred via Bluetooth by Garmin Express. There is a bar that says You need to log in to Garmin Connect to sync this device. I click on log in, I get a box Garmin Accout Sign In, I enter email and password into boxs, the next screen says "There is a problem with our servers which means express is temporarily unavailable. I have a huge event this weekend and need this to work.
Forerunner 910XT on bluetooth???? That must be ANT i think. 910XT does not have bluetooth....... servers temporarily off line is quite common, just wait a view hours, sometimes a day or so. No reason for panic :-)
Perhaps you can be more specific? Note that if it is a problem with Express there is now an Express forum staffed by members of the Express team, you will get fairly quick help if you post there.
