I saw a couple of others confused about this as well, so I wanted to describe my discovery this morning for those that were as frustrated as me in trying to "see" their music content (ipod/XM/iphone).

Set your primary screen as Navigation/Trip Info/Whatever.

Right Click iDrive->Split Screen->Split Screen Content->Scroll down to Entertainment Information (voila!)

The system, apparently, won't be able to show entertainment information in the left side of the split screen, only the right, so GO FIGURE, at least I can have my navigation run on the left and see my XM channel info/Ipod music info on the right.

Hope this helps!
