This may be a silly question but what exactly does updating the software do? Is it just a cosmetic change as far as how options are displayed on the Idrive screen or does it change how your car drives or performs?
I have a pre-facelift too and the idrive "theme" from 2002 is getting boring to me, Ive been looking at the same one for 4 years. And how much do dealers normally charge for this?
