You can upload the GPX routes via the portal and adapt them as required. When the Nyon is connected to your smartphone via a Bluetooth connection or WiFi, the saved routes are automatically transferred to Nyon.
Once the routes have been transferred, they can be started via the Navigation menu > My routes.
If your track cannot be displayed, Nyon will neither give you navigation instructions, nor calculate the distance or time. The track will be displayed on the map in the on-board computer.
If your track can be displayed, Nyon will guide you on your way with turn-by-turn messages.
