I've installed BT in my E46 but i have the mic poking out of the headliner in front of the Mirror. Its barely noticeable but its annoying my OCD.

What is the OEM location for a non-sunroof headliner ?

Ive seen a little speaker grille in the sunroof panel on some cars and the Vert has a different dome light with a speaker grille. What about the non-sunroof saloon?

Cheers.
