Using ant usb stick & garmin express with Garmin 910xt. garmin screen says "transferring data" but after few seconds, garmin express says synch failed and activites not downloaded to garmin connect. Watch goes back to main screen but then starts the "transferring data" again and keeps looping back to this.
I have done following:
reset computer
used ant usb stick in another port
deleted older activities from garmin 910
But still not synched.
