You can flick between audio, navigation, MFD and setup.
Setup has things like your coming home lights etc.
Audio displays track names, radio station etc.
Navigation gives you the directions on the screen.
and the MFD has MPG, miles left in the tank, average speed etc.
I dont know how you will navigate it without a MFSW. Someone else will have to comment on that.
