The built-in map detail level in the 695/696 is the same as the what comes in the Mapsource Worldmap CD. This is a lot more map detail than came with the older 296 which already had more than the panel-mount 530. You have to go to even better maps like the US or Canada Topo to gain any further detail by burning the map blocks to the SD card.
The IFR plates are for the US only. Anyone outside the US gets no benefit at all. They are called "FliteCharts" and appear to be some kind of .pdf copy of the National Aeronautical Charting Office (NACO) paper charts. They come from Garmin. Too bad the Jepps can't get in there for the rest of us.
