Hi Guys,

Got a few problems with my factory bluetooth microphone. Will not pick up my voice unless my gob is literally an inch away from it!! It will then recognize commands. Seems like the mic is goosed.

Looking at the part number, its different from the one which i am seeing on other mic's

Mine is: GM AZ 10/09 13255447

The other one i have seen a picture of is: GM ES 09/05 13173659

I am guessing the 10/09 and 09/05 is the month/year of manufacturer?

Any ideas why the change of serial number for the same product?
