So if you have a business CD, you need an update before you can fit.
Isn't the only change with the Business CD the way you wire in the passive crossover? Oh, and the switch on the amp? Either way, it doesn't take any more time than any of the other source options.
Looks to me like BMW may have twigged this is a popular upgrade (hence the price increase) and are now allowing dealers to make more margin out of fitting it.
Has anyone got an electronic copy of the new fitting instructions? Did the OP get the whole pdf from the dealer or just that snippet?
