IPhone 5 playlist and mercedes comand APS

Hi,

I have an IPhone 5 and a Mercedes with comand APS and media interface (not the comand online, the previous version buth with the same graphical interface).

Everything works perfectly when I connect to the comand with the adaptor. But all the playlist are empty:

+ I can browse them, but when i select one, there is no tracks at all..

I synchonized with my Ipod 5th gen with the same track, and I do not have any problem with the ipod.

Any idea?
