When trying to update the maps on my Edge Touring device I'm getting a message saying 'Oops, there's not enough space.' When I continue and select 'Choose a region' it sits spinning and nothing appears. I have disassociated and re-added my device in Garmin Express but there was no change.
Is there any stuff in your "trash can" on your Mac that might be from the Edge Touring? If so, empty it. OSx doesn't actually remove a file and free up the drive space until it's been emptied from the "trash".
