I have a 2004 S4 with integrated I-Pod controller, so it has the i-pod type lead within the glovebox that plugs straight into the bottom of the I-pod.
I don't have an i-pod so use the wife's - this drives her mad so she got me an MP3 player for my birthday today!! Problem is, it's a Zen one, so not I-pod connection but a normal USB type connection. To save her taking it back and breaking the bank getting me an I-pod, is there a USB connection anywhere? I have a couple of SD card slots under the Nav screen if that help????
