AUX port in E53 male to male connector part number

[bmwfreeq]

OK. my name is bmwfreeq but not in the e53.....lol
i had e36 1996 it was greate till i decieded taht i need a bigger car for the family. so i went stright to the e53.
now i have 2005 x5 3.0 loaded. very nice...but wait not fully loaded.
i have a nav system along with the tape, i installed my old 6 CD changer and it works fine, but the the iPod comes in place.
so i staterd to look around and signed up for this forum and found the following link http://www.xoutpost.com/electronics/...-input-x5.html which was a great tutorial for me.

So here is my case.
went to the dealer to get this part, the dealer said they have it but it wont fir my car. he tried selling me the BMW iPod interface kit for $310.00 plus tax plus the labor.

now i kinda belived him since he is the dealer, BS....
i went back to this forum adn searched a more and i found that i can use this part number 82 11 0 149 391.
Greate but my concern is..
on my car i have the male connector, and this cable comes with a mail conncetor too. so i would need a male to male 3 pin conncetor to connect to my system.
Part number???
i asked the dealer guy again and he made me look like i have 3 heads and came out of space..." we dont have such thing." " in my years working here, i never heard or seen something like that" then he cought an attitude and asked for a part number thats when i looked back at my self and said damn.

Please if anyone know thae part number it would be much appreciated.

i am trying to connect this Part# 82 11 0 149 391 to the car so i can listedn to my iPod.
am i missing anything???

Thanks in advance
