I was just updating the Maps of the Garmin Express Nuvi 2589 map/navigation unit and the download stalled or stopped completely.
The solution for me was to go in to the Windows Defender Firewall and add Garmin Express to the list of allowed apps to go through the firewall. As soon as I did that, the download resumed.
I had previously downloaded updates without any problems so not sure what changed – but if you see a similar problem (and many do from what I saw online), try adjusting your firewall settings.
