Welcome to, my name is Dustin.
I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.

Expert:  Dustin replied 7 months ago.

I know the exact issue you are facing and how to resolve it, as this is something Ive been handling and fixing for the last 15 years.

The main question I have is how do you want to work through this.. I can either guide you via written support through steps you have to carry out yourself.

Or, I can connect to your mac or pc and fix the entire issue for you, and make sure the actual maps do u pdate to your garmin.

How do you want to begin?

Ok, the steps below assume you have a windows PC.. If you have a mac, let me know as these steps wont apply.

first thing to do Is close garmin express. Then connect the garmin to your computer.

Then, hold down the windows key on your keyboard and press R, type in %appdata% and hit enter.

Now, in the appdata local and appdata roaming screens, we need to delete anything that is garmin related.

Then, go to this folder %temp%\img delete the img folder

Next, click this pc, you should see the garmin listed as a drive.. We need to open it, and then locate and delete this file inside the garmin if its present


Then, instead of garmin express, lets try an alternate program.

Download install and run the garmin webupdater

Let me know if that will successfully update your garmin, or if it gets stuck too.

I strive to provide great service, and greatly appreciate a 5 star rating clicked and submitted when you are satisfied.. I always answer follow up questions.

I ran out of time. I work two jobs and have only limited time to fix these stupid problems. I started looking into your ideas. So far they seem to be on the right track. You seem t have much more knowledge than the typical help clerk. I will get back when time permits.
Expert:  Dustin replied 7 months ago.

If time is an issue, this is something I could connect and fix for you at a reduced fee. ( the site normally charges 39$ )

All I would need you to do, is connect the garmin to your computer, then run my connection file so I can connect to your computer. And then through my connection I could do the work for you, while you watch tv, eat dinner, etc..

Ill send that offer to you now so you have an idea of the fee for that offer, but please dont take this to mean that you have to accept the offer. If you want to continue via written support as / when your time permits, thats absolutely fine.
