Using this method, I was successful in using GE version 7.10.0.0 to update both the software and maps on my old nuvi 755. So I used the technique described in this earlier post to get around this problem. This version installed without problem, but when I launched it, it gave the message about the required update for GE and it wouldn't let me dismiss that message and go on. So I updated the PC to the other old version I had access to. Apparently Garmin has disabled their current servers from using a version of GE this old. Although the old version recognized my device and even gave an alert that updates were available for the nuvi 755, when I tried to update all it would do is give an error that the Garmin servers were unavailable and to try later. If you are interested in either of these versions let me know via PM and we can discuss the best way to get them to you.ĮDIT: I wanted to follow up on this to say that I tested my installed Garmin Express 5.5.0.0 with my old nuvi 755T to see if it would actually proceed with the map update. I had forgotten how different the user interface is on these old versions. I could try that with a clone if you wish. It installed and executed without any problem and didn't even force me to do a version upgrade, although I did not attempt to add my Garmin devices or do a map update. Interestingly, I installed the old 5.5.0.0 version on an old Windows 10 laptop I have that didn't already have GE installed. I don't know its release date but I think it is from somewhere in 2016/2017.

I also found a really old version 5.5.0.0.

JanJ, I have searched a couple of my Windows 10 PC's and have come up with 2 versions of the Garmin Express Installer.
