Depending on the telematics/mobile integration, exporting a route may be a requirement to get route plans to the drivers. Also, depending on the integration, preassignment may be a required step before exporting routes. 

To export a single route, right-click on the route line and click Export. Depending on the integrations available, a list will appear allowing you to select which device type to export to.

To export multiple routes, select the checkboxes to the left of each route and click Export. The same dropdown with available integrations will be displayed allowing you to select the correct device types to export to.

You can also re-export a route via the same process.
