I have similar trouble, but my device it is a FR 310XT, truly im already think i made a terrible mistake with this device, about 80% of the offered characteristics doesnt work, im not able to transfer workouts and routes to my device, i contacted garmin support, "all the "simple" explanation and procedures" doesnt works, there are someone fix a similar trouble in their devices? im already use mozila firefox, im not use internet explorer. Thank for the help
