You can display the maps also on the Fitbit smart watch. But please don't expect the same maps app performance on the Fitbit as on a phone. The Fitbit is very slow and has very limited space. The Fitbit phone app "Sync" step, shown in the video, is very important. Don't skip it and make sure that the watch app Map Chart is closed during the Sync.
