Hi,

This is my first post on here and I need help. Iv been a browser/reader for ages.

i have a 2006 120D, I have installed a pro HU which has bluetooth built in, i can pair my iPhone and make and receive calls using the stereo but no one can hear me.

Im guessing I don't have a mic or its faulty?

I have found the upgraded mic part number but before I order that, where and how do I wire it into the loom?

Will the mic come with the relevant wire/cable to do I need to fabricate it? if so, where do I splice it into the loom?

Any help with this will be much appreciated.

Also I don't have mulf.

Thanks
