are you using it in another or in the same plotter ?

same one, I copied contents of SD BEFORE I put it in the plotter & only see GMAPSUPP.GMA, GMAPSUPP.IMG, GMAPSUPP.UNL, GUPDATE.GCD from factory card. I thought maybe another file Windows can"t see, But why would that be??

If the map is unlocked no need gma and unl files-
Gmapsupp.img must be alone in a Garmin directory in sd, if it's not the original sd, you have to unlock the chart and remove .unl and other files
