hi to all:

i was talking with another technician re: my Hualingan problem, theres video but no sounds coming out. He said maybe the other installer removed my Alpine BMW iPod interface cable of which should have not been remove in the first place. I browse xoupost and saw a link of the said BMW iPod interface, but it didnt show or instruct where to put those 4 color pin into the 40 pin harness. ( http://www.xoutpost.com/articles/x5/...ion-guide.html )

Does anyone have a link or guide on where to put these 4 colors pin into the 40 pin harness. Thanks in advance

Wow, I had no idea you had to rewire for this iPod connector. I learn something new about this vehicle everyday. Sorry, I can't help on this one. But at least it looks like you have narrowed down the issue.

I think the other technician is wrong on leaving the iPod connector in. More than likely it is designed to only work with the MID and radio. I think you are going down the right path trying to figure out the original location of these wires.

So the installer removed the iPod connector and just left these wires hanging free?

Hi NextGen:

Yes, I believe the problem is the other technician removed these 4 pins where in fact he should not and done so. Also, he didnt make any notes on which color is for which pin etc.

So when the Hualingan unit doesnt have any sound, I ask him to put back the original stereo and it was not functioning anymore ( radio not working) as he have no idea on how to put these 4 pin back. Lesson learned, don't just trust any so called " expert" on X5 even no matter how nice is their shop.

Upon talking with another technician and explaining to him on what happened, seem he make more sense as he suspect the problem is on the 4 pin being removed. Another thing that concern me is that for these 4 pins, he said 3 are positive and one negative and the first technician just leave them as is without putting any electrical tape on each pin/s.

At any rate, so excited to have stereo again in X5. Currently using iPod while driving *wink

I hope someone will have an instruction on how to put those 4 pin back.
