Quick question:

I have a 2005 MINI Cooper S, which has the exact same MKIV navigation system that many of you have.

In many screenshots I've seen of the MKIV in BMWs, I see some extra options that aren't available on my Nav. I understand what most of them are for (Television, DSP, Aux. Ventilation, etc.), but the one that has escaped my mind is the one labeled "Code".

What in the heck is that one for?

Thanks in advance!
