If I understand correctly you are trying to install a personal MapSet using MapInstall and the Maps on PC (.gmap folder).
If this is what you want to do then follow the steps below:
- Open MapInstall but DO NOT connect the Nuvì 765, let MapInstall save the Map somewhere on HD with the name gmapsupp.img
- Once the Map has been created, Unlock it with Tool:
- Copy the Map to the \Garmin folder of the Device (or to an external microSD)
I remember you that Nuvì 765 manages without problems the entire NA Map, if you put it on external SD
Furthermore, the Device manages gmap3d.img and JCV Full-Screen too
