Sync microphone please help

[Mitch12]

Hello there, this is my first post on here so first off apologize if anything is wrong. Ok, I have a 09 Ford Focus coupe SES which I bought used this summer. Sync worked great. I just had the windows tinted, including a 'visor strip' on the front windshield. Ever since this (yesterday) the Sync system will not head my voice at all. It seems clearly a microphone issue. I dont think the tint could somehow be blocking the microphone. Am I correct in that the mic is located in the rear view mirror? Could the tint affect it? or is it more likely the installers somehow broke/damaged/stole the mic? the mirror was twisted all the way down when I got my car back. I can't see much wrong however there is a whole on the back where something seems like it should be plugged in and nothing is plugged in. However, I have no idea if anything was ever plugged in there or if that is something different/extra.

Thanks for your help!
