Any advance on this issue? I created a sub-folder from my PC in the courses folder on my Garmin 1030 and it's invisible to the device! Why oh why is this so difficult! It's a peanut addition to the device facilities and I would expect that cutting it out probably requires more work than leaving it in.
I find my iPhone a much better place to manage courses. I regularly delete them from the edge. I send them when I need them. On the iPhone it is easier to filter Sort and visualise courses. I do the edits on garmin connect website. Any GPX I get I import it to connect before using it as a proper course. Works better for me than than doing any management on the edge.
Good Idea. I can do way points on my Montana 610. Categories for points of interest. Or at least have th eoption to show the closest routes and tracks.
