iPhone music connection
 

Hi I'm hoping someone can help, I've just purchased an Audi A4 2.0 TDI SE (58 Plate)
I cannot find any way to play my iPhone through the sound system. There is no aux socket or usb sockets, even in the glove box. The only option is an sd card or CD player. My phone calls work perfectly through Bluetooth. I need a solution, which doesn't involve ripping anything out. Any help would be appreciated. Thanks
