1999 323i Dashboard Schematic

Does anybody have any links or PDF files for a dashboard schematic for a 1999 323i?

I would like to try to install an FM Modulator for XM receiver myself and I am curious how to go about doing this. I figure, the first thing I should do is figure out where the antenna connection is located.

Any and all help will be most appreciated.

Thanks

Mark

Try gettin a BMW Manyal by Bently. They are the most comprehensive. I'll check my Haynes manual when I get a chance.
