now we have the same problem with Topo Fv4. Witch ImgTool you use, I only know the gmaptool, but there you cannot change header name.
I hope I am right here. I downloaded Topo4 for France with the SQL. I don't have a folder on my Garmin with SQL.
I created one and dumped the SQL (.db-file) file in it. Is this all what I have to do, please?
