I was trying to update the USA map on my 1040 non-solar and got an error part way in to the process. I assume it was because I had insufficient space for the map to be downloaded.
I looked around, and found the suggestion to delete the .IMG files from the 1040 and reload the maps using Garmin Express. I now have tons of space, but Garmin Express is not offering to update maps. Do I need to delete other file types? I also did a device reset. Garmin Express still does not offer maps to be added to my device.
What do I need to do to get to the point of loading maps onto my device?
