I found this on this site US Pacific Topo and downloaded it from
gmaptool.eu/en/content/usa-pacific-osm-topo-routable
This website gmaptool.eu is a linked I got from this site gpsfiledepot.
It did not have an installer, just .7z and no executable file. I did this in July and some how got it on basecamp.
Needless to say basecamp can see the map and It's routable but when I click Map>install maps mapinstall I do not see the map. It sees my other 2 custom topo maps I have.
I plan to install this on a Garmin drivesmart 71, same as a 65
Any help is appreciated
