I have no problem uploading my workouts off of my Garmin 510 but when I try and transfer my workouts over from my 910 it wont transfer over. It shows the 910 device but when I go to upload it eventually says "no new activities found"
He's asking what software you're using to do the transfer. Garmin Express is the new software. If you're using a PC, you most likely have an icon in the system tray (down by the clock) or on your desktop that looks like this...
If you are using ANT Agent, you'll likely have an icon that looks like this in the system tray...
If you are unsure still, you can go the the Add-Remove Programs/Programs and Features control panel and look for anything from Garmin.
