Phatbox in an X3 with premium sound?

[Larock22]

I have a phatbox in my 330 coupe, which I’m trading in for a 2006 X3.

I’m getting the Premium Sound with the X3 because I don’t want to fool around with any aftermarket sound improvements and my 330 HK system was always good enough for me.

The only problem (I think) is that I think I read on BMWUSA.com that the premium sound option has DSP and on the Phatbox website it says you may require a special adapter for BMW’s with DSP.
Does anyone have an X3 with Premium sound and a phatbox and can confirm that I need to buy the DSP adapter? If I do need the DSP adapter is that all I need or do I still need the regular adapter that I’m using now?

Also, if I have Nav and the satellite radio options will this affect plugging in the Phatbox?

I understand that the CD changer wiring is located in the center console, does the phatbox fit in the center console (or that wishful thinking), any suggestions on where I can put the actual Phatbox unit?

I hate to ask so many question but the thought of not having my phatbox in my vehicle is kinda scary, I have grown quite fond of it.

I may take this one to a car audio place to get done, does anyone know of a place in the NY (long island) area that knows about the Phatbox (especially if I need the DSP hook-up), my local guy doesn’t.

Thanks in advance for any help or suggestions you can offer, I really do appreciate it. Now my dealer said it's gonna be 6-8 weeks before my X3 arrives... (I can't wait) it's hard to believe that no dealers order X3's with premium sound.
