2011 BMW 128i 2D Convertible, N51, StandardFACTORY OEM SERVICE PROCEDURE

USB audio interface

With the Combox, an iPhone or iPod can now be connected using the customer's "original" white USB cable. This feature still requires the optional equipment iPod and USB adapter (option 6FL). In this case all data and other information, including the audio data, are transmitted via the USB cable. Because the device is now also charged via this cable the familiar Y cable is no longer needed.

NOTE: Non-compatible iPods (e.g. first-generation iPod Nanos) still have to be connected using the familiar Y cable.
