Hi there and welcome
What you need to do is download Garmin Express from my link below
Install it on your computer, then connect the device to the computer and you can perform your updates via the software
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know please how you go
Sorry about the delay, it was 2 days before you replied and I was not online
Within 2 minutes of you posting the question,. I sent a detailed response explaining the answer. It appears you missed this? But you will see it when you scroll up on this web page.
No problem though, I will repeat it below
Let me know please how you go
