Vectorial charts work with several layers displayed according to the zoom. The more you zoom in, the more details you get. With Adrena, you get a control window of the different layers you want to display. When purchasing a CMAP chart, you receive a specific DVD covering your area. You get the NT/PC Selector interface to install your chart.
