It's not clear if Business Nav got the new iDrive controller at the same time.

Thanks.

And just saw that we can't use radio/cd while the Nav is on?
And the split screens in pro Nav allows you to perform two tasks at the same time, so, if it is just a business Nav, and while I am playing songs, I have to stop the music when I want to use the iDrive for something else, such as the "climate" or "communication" function?

If so, I think I will have to search for a pro Nav BMW instead of the business Nav....
