I've got a F500BT and the cables for it are different than anything I saw on the Apple website.
The Pioneer cable came for free with the package deal, along with the amp I was hoping to stuff in my wife's 6 (mine will have audio mini jack), but sounds like that wont happen with her factory Bose system. It seems to do alright but still waiting on delivery of my car to test the quality through a real stereo (only tried on built in speaker so far ).
