Functional description

If an external audio source is connected to the AUX-IN connection via the jack plug, the audio data are transferred to the headunit via an audio line. The audio source is selected via iDrive. The tracks are selected on the external audio source.

The AUX-IN connection with a USB port can be used to connect suitable MP3 players (e.g. Apple iPod) and USB sticks to the vehicle via a USB interface and to play back the audio files stored there. The data is transferred from the USB interface to the telephone control unit. The mobile phone control unit transmits the data to the head unit on the MOST bus.

The tracks can either be selected on the external audio source or via iDrive. To facilitae selections with iDrive, a playback list is displayed in the Central Information Display.

Apple iPod devices are connected to the vehicle using the adapter for Apple iPod (Y-adapter 30 pins connector on USB and AUX-IN) available as a parts accessory from the BMW Group. It enables rapid access to the audio files on the iPod and also recharges the iPod.

Other MP3 players or USB sticks are connected to the vehicle via a bidirectional data line. This line is also used to charge the external device (with max. 500 mA). To avoid malfunctions, do not connect to the 12 V socket of the vehicle at the same time.

The playing back of music files saved on mobile phones with a USB interface is not recommended with the USB interface. Because some mobile phone models cannot be used with Bluetooth at the same time, it cannot be ensured that calls can be placed or received.

To link the MP3 player in the mobile phone, an audio connection for Smartphones is available (optional equipment (SA) 6NF "Extended connectivity of the music player in the mobile phone").

The connection of an MP3 player in the mobile phone is integrated in the vehicle system in such a way that audio playback is still possible via an external audio source (e.g. MP3 player, iPod, USB stick, etc.) but now can also be obtained via the Smartphone contained in the snap-in adapter. This connection of the MP3 player in the mobile phone is necessarily established when using the optional equipment (SA 6FL "USB audio interface").

In combination with both options (SA 6FL and SA 6NF), the vehicle is now equipped with a new AUX-IN connection that has an internal switching function. It switches the audio signal to the telephone control unit; this audio signal either comes from the eject box or, in the second switch position, from an external audio system via the jack plug or Y-cable. The second switch position is triggered when a jack plug is plugged in. Operation and navigation in the menu of the respective Smartphone is performed via the iDrive menu. Unlike optional equipment SA 6FL "USB audio interface", an additional adapter is not needed. The required connection to the USB hub and AUX-IN connection is already integrated in the wiring harness. The control electronics are contained in the eject box.
