My 2007 X3 3.0si comes prewired for sat-radio, according to the specs. This is an X3 without any options added. My questions are: What BMW part number kit do I buy? Does the kit uses the same "shark-fin" antenna and radio that came with my X3? Thanks to all in advance.

SIRIUS can be installed on the following vehicles: - 12/2003 - On without navigation
- 03/2004 - On with navigation
Restrictions? All X3’s must have SA 693 (Satellite Radio Preparation) or satellite radio cannot be retrofitted in any way.
