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?
