I noticed that this case was still not closed. I thought I would offer advice on the subject:
When dealing with an update for your Garmin device, it is best to simply download, install, and use Garmin Express.
and (if you have a Windows PC) click on the big blue Download button at center bottom of the page. (If you have an Apple, click on the nearby Download for Mac link.)
And download Garmin Express' installer to your computer, save it, then double-click upon it to install Garmin Express.
Then start the program, Garmin Express. Then connect your Garmin device. Then use Garmin Express to update your device.
(Garmin Express, and the use of it, is all free of charge, of course.)
If this answers your question, please rate my answer. A five-star rating would be appreciated!
