I am getting ready to purchase a 2007 X5 with almost every package except Sirius. It is pre-wired for Sirius however. I do plan on "doing it the right way" and get a fully integrated system, but I am picking my X5 up from a dealer in CA and driving it back to AZ. I was hoping to hook my current Sirius Stiletto 2 up for the drive back. Is there anyway to plug in the antenna, so you can use the Shark Fin? Or will I be relegated to using the round antenna on the dash?

Thanks
