The Seattle Avionics CharData Manager will load the FAA airport diagrams, and if selected, will load the SA airport diagrams on the memory stick too.

When both FAA and SA diagrams are loaded, it seems the 5600 shows the SA diagram when the MAP-> AP DIAGRAM button is pushed. Is there a way to get the AFS to show the FAA diagram instead?

I like having the SA diagram when the FAA diagram is not available, but the SA diagrams have caused me too many headaches and issues when taxiing. I've come across so many instances of taxiways not labeled, or worse, incorrectly labeled. FBO/landmark data is sometimes a decade out of date. Maybe in the settings somewhere we could choose priority?
