I know you have a US 265W, but others may not. Always best to say which unit you have, because map image naming capability does vary depending on model.
You can use on an SD card in a root folder named Garmin, two map names: gmapsupp.img and gmapsup1.img only. This is assuming recently updated fw as you have. If not, only gmapsupp.img will work.
