Can I use a route created in an online route planning tool in my ConnectedRide Navigator?

Yes!
You can use any online route planning portal (e.g. Basecamp, Calimoto, Komoot, Kurviger etc.), as all these tools have agreed on the so-called ".gpx file standard" to exchange their geo data.
You can therefore use these .gpx files on the ConnectedRide Navigator without any problems. The following functions are available for route import:

• Routes can be imported via the device.
• Routes can be imported via the ConnectedRide app

This is how the route import works.
