From the Home Screen on the watch, scroll upward to ‘Settings’ and then scroll downward in settings until you find ‘GPS’. Press on ‘GPS and you will be able to choose between ‘Dynamic’, ‘Built-in’ or ‘Phone’. If you choose ‘Dynamic’, then it will use your phone if it’s close or switch to the Fitbit if the phone is not accessible. If you choose ‘Built-in’, then it will use the GPS in the Fitbit only (but this may have a greater impact on the battery level 🪫).
Hope this helps.
