I've been using Basecamp for years. Recently switched from a 64ST to a 66SR. Nearly everything is working as expected.
But the 66SR constantly has old GPX files from trips I made on my bike months ago. They appear in the "internal storage" of the "device" within Basecamp.
I can delete the GPX files on the device, and they do not show up with Windows "File Explorer".
But the GPX files are still there.
As soon as I plug the USB cable into the 66SR and fire up Basecamp, the tracks/GPX files are back.
How do I delete them, really?
What is restoring them?
Is there some setting I am missing?
