I see a lot of SD cards for Sale on eBay which say they will add navigation to a CX 9. I am considering buying a CX 9 GS without navigation and am wondering is the SD card really all that is needed to support navigation or is there more to it?

If their screen is already there, is it easy just to get after market navigation without replacing the current system?

The car already has the navigation button and the screen for the rear view camera.
