You can do it a few ways:
Using the Wahoo or ELEMNT app on your phone; this will then sync with the head unit.
Using any of your connected accounts: RWGPS, Komoot, Strava, whatever.
You can also use a GPX file - open it in your ELEMNT app and then use it as a route.
I usually use Strava or RWGPS.
How do I download/transfer a GPX file to the Elemnt app?
I plan a ride in Cycle.Travel, download as gpx, open in the Elemnt app, load route onto headset.
Hi there
I've just recently bought a Wahoo Elemnt Bolt V2.
I've paired this with the following apps on my phone: Strava, RidewithGPS, Komoot and Relive.
How do I create and upload routes, etc and transfer routes that others have set up?
