Hello, I am facing the same issue. I want to upload my Tacx data .fit to my Garmin App. I go to Garmin Connect, and have look at all the sub- and sub-sub menu options and do not see that option. I am automatically signed into my Garmin Connect App. Considering Garmin now owns Tacx, one would think this would be straightforward, but apparently not. Please let me know exactly what I need to click on to be able upload my .fit file into the Garmin App. Thanks,
Please advise as to if there is a 3rd party app that can help me to connect my Garmin products. Thanks!!
This thread is 8 years old. A lot has changed. I'm not familiar with the Tacx, but have you tried a manual upload using the import data page of Garmin Connect Web.
