A:Answer Yes, you can link the TomTom data stream with the Map My . . . products.
No idea if it would also sync with FitBit -- but I would doubt it.
My recall is the syncing starts on the Map My Run end, eg you tell MapMyRun what device to sync with, and then a pairing commences.
Once you upload the activity data from the watch to your My TomTom site, the transfer to Map My Run seems to be instantaneous.
