Loading Routes/Tracks to SD Card vs Internal
1. Create track in My Drive
2. Save but do not select "Sync this route as a track with my devices"
3. Once saved, I can then select "Share Route" and download GPX file
4. Transfer GPX file to Rider 550 SD card via File Explorer (as it shows under Rider 550 in File Explorer) via USB connection. I would assume this would just be a direct copy into the SD card
I have a Garmin XT as well, and I do prefer using the TomTom Rider as My Drive makes it easy to create routes vs Base Camp or the other options I have used for the Garmin. Now I have to test if My Rider will import over correctly as a GPX file to the Garmin (perhaps best of both worlds?).
