: Satellite Radio and the shark fin antenna

03-30-2007, 08:42 AM
Hoping someone may be able to help. I recently purchased a portable Sirius unit and am about to connect it to my 2004 X3. I have read several threads concerning the shark fin but am wondering exactly how to tie in to this antenna. And, if I do, will I need to install the Sirius antenna that comes with the car kit. Any and all help will be greatly appreciated.
thanks to you all
