I had much better luck with the old way of uploading.......I have the 305 and the 310 xt....I sometimes have to wait days for my data to upload....sometimes it will not sync at all. Very frustrating.....maybe my gps devices are too old, my wife's pretty little pink "whatever ever it is" uploads instantly. I am running windows 8 and she is running windows 7
If you were previously uploading data with the ANT Agent and had started having trouble after installing Garmin Express, delete the device from Express then clean up the left over ANT Agent data. Pair the device with Express again and your uploads should resume. I recommend doing the 310XT first. Make sure that is working properly and then proceed to the 305.
1. Delete the contents of the C:\Users\yourusername\AppData\Roaming\Garmin\Devices\
1. Press the Windows Key + R key together
2. Type this exactly, %Appdata%
3. Click OK
4. Open the Garmin folder
5. Open the Devices folder
6. Delete the numbered folder(s) (unit id of the fitness device)
2. Delete the contents of the LegacyProxy folder located in C:\ProgramData\Garmin\LegacyProxy folder
1. Press the Windows Key + R key together
2. Type this exactly, %Programdata%
3. Click OK
4. Open the Garmin folder
5. Open the LegacyProxy folder
6. Delete the numbered folder (unit id of the fitness device)
3.Go to this location and delete any files in the sync folder: C:\ProgramData\Garmin\Core Update Service\Sync
4. Restart the computer
5. Pair the device and creating a couple of short 1 min test activities.
