There is not any problems any windows version if you just make Maps subfolder where ever your basecamp is....
copy GMAP folders to Maps directory.... just like picture show it
If I copy to C:\Program Files\Garmin\BaseCamp\Maps it works.
But I have other maps in C:\Program Files\Garmin\Maps which work to and in this folder I can use in both Basecamp and Mapsource.
Why can't I use Garmin\Maps\ for this map?
Now I can open the map in Basecamp but can't transfer to the unit!
When I go to MappInstall it says that the device already has the last updated maps and it doesn't let me select the Europe NT 2014.40 only the other map I have in the Garmin\Maps\ directory.
And yes, I'm pretty sure I don't have Europe NT 2014.40 on the device yet.
You have to navigate to get to the good.
