Garmin 310xt Sync Problem

For the last few months the Garmin has been playing up. It began by not automatically synchronising with the PC and then started failing to download workouts. I have no idea what the cause was, but after some web research, i found it was a fairly common problem. The explanation was that somehow the data on the 310xt had corrupted. I found this hard to believe as the device was quite happily storing run, bike and swim data. Following some frustrating screwing around, I found I could upload activities by re-pairing the device with the computer each time. There appeared not fix for downloading new workouts.

The suggested fix was to factory reset the device. This is accomplished by:

  1. Turn the device off
  2. Hold down the “MODE” and “ENTER” buttons
  3. Momentarily press the “POWER” button

I didn’t really want to do this – psychologically there is part of me that says “Well, its half working, perhaps i should just put up with it.”. But another voice says “Are you nuts? This watch cost and arm and a leg! It should work reliably and flawlessly.” Today, I had a some spare time to take a shot at it.

Be warned there is no “Are you sure?” prompt and the procedure above restores the device to an “out of the box” state. On powering on you have to fill in all your stats again and the workouts and activities are cleared. It effectively cold-starts the GPS too, so it may take a while to re-acquire the satellite lock.

After filling in my stats, I tried to pair the device to the PC. I set the ANT Agent to pair with new  devices and power-cycled the 310xt. When it came back up, the pairing process kicked off and I followed the prompts as normal. This resulted in the ANT Agent throwing an exception and crashing. “Great Start!”, I thought. The I remembered the corrupt data problem and renamed the Garmin folder in the “AppData/Roaming” profile area to something else.

Pairing the devices again worked and the crash did not occur. I started Garmin Training Centre and got a warning that it couldn’t find my old profile. I ignored this and entered a new one. It automatically found the device and created a set of default workouts. I then selected the send data to device option and waited for ANT to sync. Again, this happened with no issues.

It’s early days, but hopefully the problem is solved. I just need to reset all my preferences for displays, alerts, etc.… But hey, the probably needed a clean out anyway!
