iPhone integration

[jmiller427]

What am I missing here?

I just traded up my '07 for a 2010 with the newer iDrive.
I'm trying to get my iPhone 4s to play music via iDrive.
I have the Y cable plugged into both the aux and USB in the center console, and the other end into my iPhone but its not working. When plugged in I go to "Music" on the iPhone and it will flash every few seconds or so "accessory connected" but then goes back to the iPhone music screen. I never get the connection in the iDrive system.
I've tried the same with an iPod (4th gen), my old iPhone 3G, and an iPad 2 and all 3 of these devices connect, show the name of the device on the iDrive, and allow control from iDrive.
I have rebooted the iPhone.

I've searched and searched and can't find any compatibility issues.
My build sheet shows both "music interface for smartphone" (6NF) and USB audio interface (6FL)
Production date is 11-24-09.


Any help is appreciated.
Thanks!
