I've explained why the documentation doesn't match the display. I'm not sure what it is you don't understand. The published document is for old version of the software on the touch screen. You are probably running version 2.10. Before I upgraded the software in my icon cs matched the document. They changed the user interface drastically but they didn't change the document.
My display is all digital (no tach needle or replica gauges). It looks just like the 3.5 cs only not in color and with several different screens.
I am most concerned that winterization is just selecting that option and following the on screen instructions. :-)
