I just made a aux input cable for BMW E46. 
Last time I checked from dealer, they asked for $60.
Seriously, I don't want to spend about $60 for a stinking cable.
Before start, you must have a OEM Business deck with MODE button.
Let's get started.
1. This was male on both end and I just cut one side.
2. Close up
3. Some people might wonder what this is.
This is a cable that I found from my old computer I was about to throw away. This pin connects to motherboard for power switch, reset switch, hdd led, power led, etc.
Do not cut the other end of this cable, just pull the pins out. It will help you to solder it.
4. Getting prepared for soldering.
red/black(sound left/right) goes into pin 8/9 and yellow(grounding) into pin 4.
5. 3 small and 1 big heat shrink tube.
6. Ok. It is done.
7. From HU, pin 8,9(left,right or right,left don't care too much. ) and pin 4(ground) need to be connected.
You will be surprised how well it fits.
8. Finished
Total cost $0. Because I found everthing I need at home and it works great.
