True it went into the 740s, but it wasn't unlocked. Hummmmm

drag the gmapsupp.img in its window then push details and look if you can see if it's locked or not-
If unlocked probably you put it in the wrong place or it has to be renamed
eg of a locked map log

Your unit cant have maps in internal memory, just in sd- In sd maps for plotters are named gmapsupp.img and are in a Garmin directory, one per sd.
Enable extensions in Windows to see if it's not named gmapsupp.img.img
