He was likly refereing to the AUX input that is standard on the E70 (in the center console)...which allows an audio only connection to the stereo. I am currently using this for my Ipod, and yes I have to control the Ipod from the device itself.

The 6FL option add a USB connection to this input which allows full control of the Ipod or certain other MP3 devices.
