So I am making my own "bluetooth hands-fee unit" for my Commander. I was able to splice a 1/8 jack to the speaker of the bluetooth and plugged it in to the aux jack on the front of my stock radio. I can hear the caller through my speakers, but now my problem is that "the unit" is too far from my mouth for the mic to pick up my voice adequately. I cant amplify the mic too much or I'll get feedback .... and I'll need to "hardwire" the unit into the Commanders electrical ... prob to the "hot" from one of the cigarette lighters. I know that I will probably need a resistor to bring the power down so I don't fry the bluetooth unit. The goal of this project is to put the unit behind the dash and splice into the speaker wires and then use a couple of buttons modded nicely to the dash to control the on/off and to flip from the radio to the bluetooth unit. Does anyone have any thoughts on this or ideas on how to get better reception from the mic? And for those who are going to ask "why" .... because I can.

I think that has to be one of the hard things for the uconnect type devices to do. Basically cancel out the frequency from the mic that it is amplifying for the speakers. Without going high tech I don't know how you are going to get the mic too far from your mouth. If it is a decent bluetooth thing then maybe it has the brains in it for cancelling the feedback. I would try to either amplify the mic a LITTLE or possibly try other microphones. Mics for different purposes have different outputs. Possible a hign output mic that is somewhat directional???
Using an amplifier has many issues it brings to the table, like impedence matching, distortion, possibly overdriving the bluetooth input, etc.
Keep us posted.

Where abouts are you placing the mic?
I'm trying to "find" either an OnStar mic or one of the BMW built in bluetooth mics. They seem to just snap through the head-liner over the drivers head. For the time being the mic is a spliced computer mic sitting down on the gauges aimed right at the drivers head. It seems to be working just fine with that, but the computer mic is a directional mic ... meaning it has to point right at the source of the sound. Our hack job seems to be coming together nicely. The next hurdle will be to figure out how to run the electrical to the headset without the headset going into "charge" mode ... which causes it to turn off. I'll post some pics when we're done with details .... To Be Continued
