Ok well it seemed I ran into a glitch somewhere but I will give my steps and maybe we can see if I am on the right track
Steps:
1. Download the .img file
2. Download GmapTool
3. Loaded the .img into GmapTool
4. Choose "Split", selected directory, and choose "Create: files for Mapsource", did not choose "Compile Preview Map" or "Set Mapset ID"
5. Choose "Split all" and let the process complete
6. Download MapSetToolKit.1.77(other versions might work but this is what I used)
7. Open MapSetToolKit.1.77
8. Press "Select Img"
9. Choose the folder that GMapTool output to(from step 4) with all the 12345678.img files
10. Then used the steps from this website...
[Please Register or Login to download file] Upon opening Mapsource it seemed to work. I had all the img files and the map dropdown contained the BlueChart v11 map.
However it seems that either the map has so much detail that my PC cannot load it all or this will just never work. This did show promise but not perfect.
Attached is a screen shot of what I get. If I zoom in on a piece of the map I loose the map all together. If I change the detail level from Highest to High I get some change but any zooming will loose the map.
I don't know if I am trying to put a square peg in a round hole here but this might be a start or maybe set some better minds to work
