Navi Professional and travel book via ConnectedDrive

In the multimedia equipment manual, especially for ConnectedDrive[CD], the option “travel book” is described. However, I don’t find this option in the CD menu. Is this a special equipment that you have to book extra (but I didn’t find anything in the CD’s online portal), or do I need the Navi “Business”? Or did BMW even throw out this option tacitly in order to sell their “electronic travel book” better? I’m a bit confused… Did any of you have the “online travel book” via ConnectedDrive and can explain it to me?
