I've tried all suggestions about reset, cables, other notebooks, indeed OTG on my smartphone, but my Edge 530 just charge.
I would like to transfer files to my Edge 530, particularly a new map. I don't know another way to transfer a map.
The phisical connection with my smartphone via OTG cable keeps just charging. The try to change to transfer files manually failed.
Some updates before (actually 7.10) I have used to connect my Edge 530 to my notebook to transfer files.
The Garmin Express does not recognize my Edge 530 too, unfortunately.
Any kind of new tries? Anyone have passed by the same?
