Here is some more information and pictures of installing the AUX connector at the radio module iteself, instead of upfront behind the nav screen.

DIY Aux connection at the radio module

Yes, it is from september 2003, and has NAV. I just checked a pdf file in the articles, and it seems that the aux cable which needs to be connected in front (behind the nav screen) has another connector than the trunk-mount version... So I do not see how I can connect the first one in the trunk ...

Ah ok, this makes it clear, thanks, ignore my other post then :)

Drex is right on. If you have a Sept 2003 X5 then you should have a connector in the front for the AUX. That means you can choose where you want the connector to go: in the front (for a glove box install, etc) or in the rear at the radio module. You can do either one.

one more question here : how can I solder RCA female jacks onto the AUX connector end ? Split the brown cable ?

Thanks!

basically, cut off the phono plug and solder ground to the white/brown, left to the white/red, right to the white/blue

sorry for thread hijacking but im looking for a temp fix in connecting my ipod [ had dension ice link in last car ] .
ive got the tv function with the sat nav option and have aux in and out ant the rear foot well [ see pic ] .
now can i link my ipod with stereo jack leads from the out in the ipod to the in on the panel here to get sound .
i know i cant use the steering wheel controls and im getting sick of the radio after 3 days all ready no single cd/ changer.
Was a demo car and the garage blew there budget before they could fit a cd changer

thanks for any info

ok, but I have two grounds (one for the left RCA, one for the right RCA), so I just split that brown cable ?
