Hello Everyone,

I just bought a 2005 BMW X5 4.4 and it is an incredible machine. I really have enjoyed the V8 power and its smooth handling. I'm coming from a 2003 330i in which I installed a OEM AUX input with no issues whatsoever. I ordered a OEM AUX cable for my X5 with Business CD, no NAV and DSP and have attempted to install it over the weekend but have had no success despite instructions and general DIY knowledge. I only have one plug going into the head unit that has 12 pin connections. I figured I would have to pull some pins from the AUX cable and insert them into the radio harness cable since there in so plug for me to plug into but have had no luck. I have attached some pictures to help anyone identify my problem. Please help so I can finish this project. Any help is greatly appreciated.
