Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
To get started, I need to know what type of computer you're using.
Windows XP, Widows Vista, Windows 7, Windows 8, Or a Mac.
If it's a Mac, please check the OSX version as follows.
Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
Also, if you would prefer I can connect to your computer from here during a screen sharing session. This will allow me to access your garmin device through the computer, and then update it directly on screen.
Would you like to try a screen sharing session so I can fix this in person? Or would you prefer that I assist you via written support only?
Thank you for your response,
Senior Technician and Network Switching Systems Operator / Maintainer.
