With a Mileage Book Subscription with accompanying tracker, you can set up schedules to control when your tracker should automatically register your trips.
Go to User Setup > Schedule
Here you can choose when your tracker should register driving. It is only possible to have one schedule and in the period you choose it will register all trips regardless of whether they are in connection with business or private. If you therefore run private tours within the time period you have chosen, you must remember to assign these tours to Private tours afterwards. Read more here about tour types.
