HELP* Strange on-board wiring harness (AUX problem)
 

Hi everyone

Iam trying to add AUX input in my 2001 e39 m5, I have done this before in my 2006 4.8 x5 and it was easy to do.
But in this car i cannot find the AUX cable that come with the wires for on-board monitor , I have the original bmw part for the AUX to be connected in this area.
In the X5 i find the AUX cable and i just connect it with my AUX part.

So what do you think.

Is there any other solution.

I have tried to use the CD changer cable in the back but it doesn't work.

Tell me about the other solutions.

I want to install AUX input so i can connect my world space satellite radio.
looking now for any solution. I just want to found any wires that carry the sound in the car so i can connect my part.
No need to change the whole wiring harness .. There is sound signal moving in the car(from CD changer& navigation unit& radio)
I just want to find the cable that carry the sound signal.
I don't have any problem in putting the AUX instead of CD changer or radio(because I don't use them at all)
