I just wanted to let everyone know that I was able to install the AUX Connector along side with the iPod Connector in my Car, both of which are the factory connectors from BMW.
The iPod disables Sirius and the 6 Disc Changer; bu the Aux disables nothing. I had to remove the black connector from the back of the radio move the yellow and black power cables into my new connector as per BMW's instructions.
Both operate 100%, the only issue I have is I will need a ground loop isolator as there is a definite whine on the AUX linked to my gas pedal.
Just wanted to let everyone know that both BMW Factory connectors can be installed on the Business CD Radio in my 06 BMW X3.
