Apologies if this has been covered before I tried to search any outstanding threads!
I get an error message when trying to sync a newly created course with my Edge 810. It just says there is a 'transfer error'. I've tried rebooting the Edge, rebooting the MacBook, deleting & re-plotting the course. Nothing works.
How can this be fixed please? The Edge & the Garmin Express/Connect are all up-to-date with patches.
Any advice please?
Many thanks
