BMW audio question

[Priit Varik <Priit.Varik@xxxxxxx>]

Hi,

I was reading the 530i specifications on the 530i site (http://www.530i.
org/530i-Stats.htm).
An excerpt from the spec sheet:

"10 x 25-watt (250-watt peak power) amplification, 10 speakers, diversity
antenna system"

Now my questions:
1) what is the diversity antenna system? I've seen on my BMW Bavaria CDII
also
the diversity connector, but it is unconnected. Is it possible to install
the
diversity antenna afterwards?

2) where are the 10 speakers fitted? Counting the ones in my car I end up
with
only 8 speakers: 2 on the front door triangles, 2 on the dashboard,
2 in the
front side panels and 2 in the rear shelf. Where are the missing
two?

Thanks,
Priit.
