Thanks!
BTW... no need to unlock for HomePort use, but if I do, Fast IMG Unlocker does unlock all images for me.
Setting the transparency with GMapTool was the only step I needed for HomePort to display this particular chart.
Having to use GMapTool to do this should not be needed though.... an over-site on Garmin's part I guess.
