Just purchased my first Audi, a used 2010 A3 2.0T Premium Plus. I can link my Android phone for phone audio, no problem. However, is there a way (without replacing the whole head unit) to easily upgrade either the firmware of the stereo or other to play the MUSIC from my phone as well? There's no ipod connector in the glove box so can't use Tune2Air or similar.

I've searched but haven't found anything so far. Help appreciated!
