This means, however, that you can not switch individual TYP files on and off: you can only switch entire families (i.e., maps) on and off. (Unless there is a clever way of doing this which I am not aware of.) If you wanted to have the same map but with different TYP files, you would need to add multiple copies of the map, each with its own ID and corresponding TYP file, to the gmapsupp.img file. (And as far as I know, TYP files must have both a Family ID and Product ID equal to those of the map. Is this correct, or is it possible to have a TYP file with only a Family ID?)
