Information about Navi 9-3 II

Hello! Is there any information about the navigation system for the 9-3 II. Above all the following topics would interest me: Which countries includes the Navi? Are the maps on DVD or directly in memory? How current are the maps and are there updates? Can you listen to CD next to the Navi? Can you load Point of Interest? Is there a 3d function? What functions does the Navi have? How is your experience with the Navi, is it reliable and accurate? My dealer unfortunately doesn’t really know and The navigator didn’t work in the front of the car?
