Garmin Please Have Some Mercy

If something is so large that may takes too long to download, there are several ways of doing that, like having a button to pause/resume download, use offline installer, and download by segment. However, Garmin be like "you didn't finish the download in three hours then better luck next time".

I feel like I need to move to somewhere with better internet to update my devices.

Edit: during my first stall, my task manager shows like 80 kb receive.

Generally you can pick up where you left off.  But I think you need to investigate the cause, otherwise it might just result in a repeat situation.

A few questions:

1.  What is the device you are updating?

2.  Do you have additional memory added to the device?  This is typically a microSD card?

3.  Have you tried other USB ports on the computer.

4.  In a laptop, power management may shut off power to some USB ports so make sure you are plugged in.  Check the USB ports for power settings.

I was having trouble with this, too, and decided it was the horribly narrow bandwidth of my home Wi-Fi network that was responsible. Took "forever," but it finally finished.

Mine started over from the beginning, didn't save from before.
