Hello Roger and Welcome,
No worries about not being to "savvy" - I think I can help you with this issue.
The current program that Garmin uses for almost ALL updates is called Garmin Express, and I have a link to where you can get that program onto your computer below.
NOTE: There is a video on that page that shows how to get started with this program. Please take a few minutes to look at that video and then let me know if you have any trouble downloading and installing that program on your computer.

Please let me know what happens or if you have any more questions.
Thanks, ***** *****
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
