I have just received a refurbished Edge Explore back from Garmin after a USB issue with my original unit.
The maps on it are described as 2017.10 but I'm sure my old one had the 2019 maps on it even if I hadn't been able to updated it for months because of the USB issue.
I tried "check of updates" nothing found and a "reinstall maps" and after 2 hours they are still 2017.
How do I update them?
