I have a tom tom multisport cardio watch. For the last week the watch syncs with the sports app but the data is not transferred. The watch loses the data but the app shows that the watch has been synced but with no data.

    Did you get any error messages while syncing or did it hang up at all? Have you first installed the Connect software and is it running? The software must be installed and running prior to plugging in the watch. If you are using the phone app, once you have synced by phone you cannot also sync by computer, it is either/or. Once the watch thinks it has a successful upload it clears the memory (what you are seeing in the History is just summary data points, the actual activity is deleted once synced). If using an app to upload, the app needs to be open and active. Also make sure you do not separate the watch and the phone during the sync process. You should put the watch on top of the phone and leave it there. If you get out of BT range it will fail. Make sure you have strong signal on the phone (Wi-Fi is even better). A weak signal will slow the process and can cause failures. I recommend using the computer to sync as it is much more reliable and much faster. Also, when you upload activities using the TomTom Sports app for phones and mobile devices, backup data files for manual import like fit or tcx files are not stored on your computer so it is best to use Sports Connect on your computer if you need those file types for manual uploads or you want a more reliable syncing process.

    If you can find the ttbin file you can force an upload (if there is no ttbin it is lost). To force Sports to reupload an activity you need to do the following:

    1 - Exit Sports Connect on your computer (you must use a computer to reupload – right click on the tray icon and select Exit).

    2 - Locate the ttbin files (if they are not there the activity is lost and not recoverable - what is on the watch is just summary data, all the detail is gone). On a PC the ttbins are saved in a dated folder for the date of the activity under C:\Users\{User Name}\TomTom Sports\{Watch Name}.

    3 - On Apple Devices, connect your device to the computer, open iTunes, select your device in the iTunes sidebar, select Sports on the Apps tab under File Sharing and the ttbin files are listed on the right-hand side. Right-click (Mac: ctrl-click) a file to copy it and save it to your computer. In Android, the ttbin files are stored on the internal SD in (/sdcard/TomTom_Sports/[serial number of watch]/workouts/uploaded/).

    4 - Copy them to your computer

    5 - Place the ttbin files in the serial number directory:
    Windows: C:\Users\[user name]\TomTom Sports\[serial number]
    Mac: [home dir]/TomTom Sports/[serial number]

    6- Restart Sports Connect and connect your watch

    7 - Go the Settings page (click the gear icon on the top right) and press the 'Try again' button to re-upload the files.
