Stock Business CD - What is this cable for?
I have a 2001 330i and recently replace the stock Business CD with a 2003 Business CD that will support the Sirius radio add-on. I replaced the antenna cable in doing so, but I'm left with a cable that has no place to fit in on the new Business CD. What is this cable for (I've outlined it in blue...sorry for the bad angle)?

Hard to tell from the picture what the cable goes to. Could you snap another pic? My guess the cable is the second antenna?

Diversity Antenna
The older Business HUs had two antenna leads. The "extra" antenna lead you have left over is the diversity antenna which is not used on the newer 2002+ Business HUs. I just tucked it back when I replaced my older Business HU with a newer 2002+ Business HU.

Cool, I've also tucked it behind with the rest of the wiring. Radio seems to work fine. Thanks for the replies.
