On the Home page, click Deliveries then Scheduling
Click on the Optimise Route tab
Use the search filters to find the sites that you want to optimise, for example a route or everything with a postcode starting "NR1"
Click the Options button on the toolbar and click the Optimise button
All sites currently in the grid will be optimised and the map will be displayed
Use the tabs underneath the map to view either the original route or the optimised route.
On the optimised route tab, you will be able to hide the markers and show the original route at the same time using the checkboxes in the bottom right.
