enable in Options tab , advanced options,
open Split tab and compile it like it's shown here:
create a directory (here C:\Documents and Settings\Desktop\Bluechart for MS) and give your map a name the one you'll have in MapSource,
in Create window select "files for Mapsource",
check "Compile preview map" and "Create TDB for marine map"
set also mapset FID with the FID of your BC (in this case 2028).
Then run Split all.
GMaptool will create, in your created directory ,the files to install your BC in mapsource.
Open that directory and install it running install batch inside-
You'll have it installed in Mapsource
but also in Homeport and you can create routes and print your map with routes.
not all the Bluecharts features will be supported in this kind of maps, but we'll have printing enabled
