How to play iPhone music through maserati grandturismo stereo system?

Hello
I have connected my iPhone trough bluetooth. Please can you say what to do next.
Thanks everyon.

Call Apple and get them to make you an iPhone with full Bluetooth rather than the crippled version they install. iPhone Bluetooth won't do music this way. But of course you don't need BT, the 2010-13 gts have the dock. Press the button next to the ac memory that has a letter A on it and the tray will slide out.
