I have created a route in My Drive and wish to save routes to the SD card if possible and desired. It seems the option to do this would only be via manual process as I could not find a setting or preference on device or the app/site to default to an SD card rather then the Rider 550 unit drive/storage. It seems I need to follow this process if creating in My Drive to store to the SD card:
- Create track in My Drive
- Save but do not select "Sync this route as a track with my devices"
- Once saved, I can then select "Share Route" and download GPX file
- Transfer GPX file to Rider 550 SD card via File Explorer (as it shows under Rider 550 in File Explorer) via USB connection.
