Currently to synchronize your marks, tracks, etc., you would have to exchange files. You would save your information onto an SD card or jump drive using the “Import/Export Wizard” under the Maxsea logo. Then bring that storage devise with you to the boat and upload it into TZ using the same “Import/Export Wizard”. Could you save this information to a cloud server, yes, but if you are the only one using it then I don’t see how that would make synchronizing your information any easier. Automatic pushing of user information and data to, say a “My Maxsea site”, is for possible future development.
