Hands Free Phone Mic - quality / performance / position, is unacceptable.

So how big a job is this? How easy is it to run the new cables in?

It's all pretty easy - i soldered the new cables in but you could crimp them. It would be a definite warranty issue though, you need to cut the loom in three places, including around the ecall unit. I routed them from the roof console down the driver's side A pillar and into the head unit.

Do you know where the head unit is ground to and do you have any pictures of the grounding point? I’m wondering if this can be improved rather than reroute the wire from outside the harness.

It has a chassis ground connection directly behind the head unit in the driver's side footwell. Unfortunately the issue isn't poor grounding, it is crosstalk between wires in the loom. At least it was on mine.

Would attaching some of those circular magnets around the cable make a difference?

I don't have the guts to do that while the car's under warranty, but great to know there's a fix.

Today I removed the panel and fitted some sound deadening and sound absorption materials. Currently, my hands free experience has been mixed. Always easy to understand but sometimes I have complaints concerning quality of the call. I am hoping that reducing resonance around the mic might help. Will update over the coming days.

I see there is a microphone to the E call? Where is the microphone to the infotainment system located, do you know?
