HELP! Which cable is Sat antenna in shark fin?

[x3and5]

Working on taking advantage of factory satellite pre-wire features to help me "hide" my aftermarket Sirius wires (Stratus 5) on my 2005 X3 with (SA 693, DSP I believe) Business radio/CD. I've read numerous threads, shopped at MyRadioStore and I think I understand how to get power to it w/o cigarette lighter. Also read tips and tricks to install aux input.

ISSUE remaining:
My understanding is that PRE-WIRE includes sat radio antenna in the shark fin which means I don't have to run wire or stick another antenna on the roof... where at the FRONT of the car is the beginning of the satellite antenna cable and how can I get it connected to the Stratus 5, cradled next to the dash unit? Cradle has "typical" male antenna connector that would take antenna wire.

Thanks!
