have you seen one installed???

So if an ipod is connected to the AUX it would be a "stupid" connection. Meaning all the controls would HAVE to be made from the ipod...??? Correct???

Thanks to all for your comments on this issue...

that's correct... into the aux is nothing more than connecting a generic head set type input plug.. everything is controlled through the iPod itself..

it will still work, and the sound will come through your system but not controls..

wife has this on her car and it works well for her....

me, I rather have the steering & idrive controls that come w/the factory installed 6Fl option

what about "ipod your BMW" ???? that does not work either??

I have bought the OEM iPod adapter accessory and it is fully functional, menu is displayed, iDrive controls and the cable charges the iPod.
6FL USB is a factory option, cannot be ordered after the car has been delivered - this iPod adapter can be ordered instead.
The only limitation is the lack of connectivity with other USB devices, such as pen drives (it comes with the iPod proprietary connector)

Is this the same option that the e53 has?? You know, BMW1,BMW2, etc..???

I have no idea about the one for E53 - might be. Here is how it looks like. Btw it is an Alpine product (written on the unit), but listed as BMW original part.

Thanks for the diagram!!! A part number would be nice...
On the e53 solution , you only have access to 6 playlists which you have to pre-name to BMW1-6...
