- Add a Widget, go to its properties and enable the Track Map
- Set the Widget Data Set to trackmap
- Add a SubWidget (to this same Widget) which will act as the template, e.g. the SubWidget that will be displayed for each car on the track map.
- Go back to the Widget properties, under Track Map category select the Template Subwidget you just created.
- In the SubWidget add a Label and set the Data Binding to (for example) carnumber, or name or whatever fits.
That should be it, now just make sure at least one driver is "selected" to display on the map using the Track Map menu (both in ATVO and in the Theme Editor).
