I use button #1 to call up "sport mode configuration".
It's very handy if you have the adaptive suspension, as you can switch between modes by easily and quickly accessing the config screen.
#2 is radio/sat stations
#3 is tone/eq settings
#8 is the trip info
The rest are some random things.
I don't have NAV.
Great functionality to cut down on having to scroll and push a number of buttons just to get to what you use regularly..
The light touch to show function is very cool and handy.
