Verify Data on Device
From MB Wiki
If you receive an error message such as, "File may be corrupt or MB may be experiencing technical difficulties, please contact customer support" or "Activities were discarded because they did not have enough GPS data", you can troubleshoot to see if it's a problem with your device or with MotionBased.
First, check to make sure your uploads to Training Center are correct (PC users only). Make sure you have a map and a graph of the data. If you don't, there could be a problem with the data on the device.
To see if there is data on the device (Mac & PC users), follow these steps (performed on a Forerunner 305):
- Select "History"
- Choose the appropriate activity
- Select "By Day"
- Select an activity
- Select"View Laps"
- Then select the highlighted lap
- From the drop down menu select "View on Map"
You should see a little map with the lap information on the right side of the screen.
If there is no map then there is a problem with the data on the device:
- Old data is being purged as new activities are completed; the device will make space for itself if you haven't deleted the history from your device.
- There may be a problem with the device.
- Clear all of the user data.
- Make sure you've installed the latest firmware version.
If after following the above procedures you find that the data on the device is still good yet are still having problems, contact customer support (mailto:support@motionbased.com)
