Your dealer will go over the options, but im not sure Id describe them as 'mods' unless something has recently changed. You can already control your windows for just about any bmw from the key, has been so for years already, and depending on which model and options, you can have a button in the car that allows you to fold in the mirrors, but they have nothing to do with a cpu mod, just normal operations of the cars
