Dotted maps gives you an overview of the route.
After entering addresses in IBI, you can get an overview of the route in IBI Start and IBI Go. In one glance, you will see the whole route with stops.
The red, numbered points represent the stops to be visited. The green dots are the deliveries that have been fulfilled. If you click on a point, detailled information about that stop will be shown. In the IBI for Android, you can even start navigating from here.
