Any ideas? There are three of them on the interior roof of my Ford Fusion.

Thanks!

 

Alright...I have an answer for you. It's a microphone for the hands free calling. I asked why there would be three of them and he said his guess would be so that the caller on the other end could hear you no matter where you are in the car. He said his pickup has the same thing but only has one of them and its right above the drivers seat

 

thanks for the information Adam..
