I have a 2007 NBS silverado with Onstar.

It looks like there are microphones overhead to the left of the driver and in the center console.

Has anyone tried to tap into these speakers and use them as the microphone for the bluetooth module?

Is there any tips/ issues?

Is it as easy as running a wire with a 1/8 jack from the BT module and then splicing into the existing microhpone?

Have you done this yet? I am trying to figure out if it is worth it to tap into the ONSTAR mic of my 2002 Saab 9-3 CNV. I have a Avic 700bt and I one, don't know if the finished product will work, and (2) how to go about splicing and stuff.

DId you do this... or give up on this dream like I am very close too. Spent 2 to 3 days scouring the interest for this...nadda yet.

I gave up.

The sound of the stock mic is so much better and looks better but I wasn't sure how to do it myself....so I just went with the pioneer one.

Do you still use OnStar? If not, you could always pop open the mirror and install the Pioneer mic in its place. I'm sure it could be done with little effort and a small amount of ingenuity.

Lots of questions and few answers. I have a C6 Corvette w/o OnStar, but I purchased new A pilar trim to build custom tweeter mounts. The new pilar pieces have the 2008 OnStar mic with two wires: one red, one blue.

We know the Pioneer uses a mono 2.5mm jack. I just need to know which wire should go to the tip of the 2.5 mm and which goes to the base. I've read that the OnStar mic is pretty good and I like the OEM look and placement.

My initial thought was to dremel the factory mic to pieces until all that remained was the grill and then use a hot glue gun to attach the pioneer mic, but I like the concept of using the factory mic. I just don't want to short out my head unit in the process.

My questions...

If someone has done this, can they tell what wire goes where?

Or

Can I meter the wires for resistance (or anything else) and figure out the polarity?

Or

Does it matter, for example a single speaker wired out of phase still works and sounds fine, until other speakers are added- since there will ever be a single mic, this may be much to do about nothing.
