Check with Gmaptool what is this map FID.
Drag the gmapsupp.img in Gmaptool window and hit Detail tab, in log you'll see map FID.
If it's greater than 2200 your map won't work without a file mamed gmapsupp.gma.
You must unlock the gmapsupp.img by gimgunlock.
After that remove gmapsupp.unl from the sd.
