The Settings Wizard is designed to help new and infrequent users to configure Vehicle Tracking correctly. The wizard does not allow you to edit all settings, but on every page there is an Advanced button that takes you to the appropriate page of the Settings dialog for more detailed settings.
Also on every page is a Finish button. This applies any changes made so far for the current session only. If you want to make the changes apply to future sessions then click Next until you get to the Finish page.
