Just ordered 545i 6-Speed with DVD Nav and Sirius Radio (along with many other options), but factory sent invoice back to dealer advising Sirius was incompatible with DVD Nav...anyone else hear anything like this...they make a rather big deal about it's availability effective Dec '03 on BMW Buzz at BMWUSA.com and further expand on new "sharkfin" antenna as being larger than on 7-series to accomodate gamut of GPS for Nav, Telematics, Cellular Phone and Sirius Satellite Radio...what gives?

 

Does the fin antenna not come only with bluetooth or bmwgsm?
or will my car, with Nav and no bluetooth, still sport the fin?

cheers
