The Y connector does the decoding of the mp3 data to audio (and outputs to the AUX socket) as well as charging the iPod/iPhone, and it also manages the interface so that you can control track selection and see track information displayed on iDrive. Unless you use something else that does all of this, it won't work.

Cars with nav have the decoding and interface built into the iDrive and so don't need the Y cable to do these things, just a USB connection
