Now you should be able to zoom in and out and see 1' contour lines.
It does not matter which card slot you put the card in and it does not really tell you it is working or anything. It just adds a ton of detail to your base maps in the SI unit.
If you do not figure this out let me know. I can walk you through it on the phone.
