The app passes the GPS heading (whatever GPS reports) to routing service. Then routing service is responsible to calculate a route in preferred direction. I mentioned how to test those routing services with the “heading” parameter: > [@Navigation stops after several rerouting attempts](https://forum.kurviger.com/t/navigation-stops-after-several-rerouting-attempts/4952/41): > > [GraphHopper routing API](https://docs.graphhopper.com/#tag/Routing-API) (and Kurviger) support heading directions. If I remember correctly BRouter does not support heading directions? (so the preferred starting direction of the route can be any) Please check carefully the calculated (re)routes and reproduce them in Kurviger / BRouter sites. If a routing service insists calculating a route, the app can receive and use it or ask a new one. --- _[View the full topic](https://forum.kurviger.com/t/navigation-announcement-incorrect-when-driving-the-wrong-way/4989)._
