Subject: RE: Can't download from Polar RS800CX after Windows 10 upgrade... Originally posted by GaryRMI upgraded to Win 10 and went to sync my 910xt. Garmin Express won't recognize the Ant stick. Submitted an email incident to Garmin. Looks like there are a few items that still need to be worked out with Win 10. FWIW, I do like Win 10. FYI, its working now. Reinstalled the ANT USB drivers but didn't work. This morning I went into Control Panel | System | Device Manager and it recognizes the stick. Bring up Garmin Express and it syncs perfectly. |
