Is it possible to set microphone volume? - Android Head-Units

I bought this unit: http://www.amazon.com/gp/product/B0151KNXJ8?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
I know it is a known issue that the microphone quality is bad, but I'm not willing/able to open the device and tinker around with the motherboard. The microphone quality would be acceptable to me if it would just be a bit louder (increase microphone gain). Is there any way we can get access to a volume control that would just record the sound a bit louder? Any other software based options to improve the mic quality for phone calls and voice commands?

I have this one in one car and a KD-C0224 in another car. In both of them the speech quality has improved dramatically after I connected external microphones that were included in their boxes. The sound quality of the built-in Pumpkin microphone is indeed pathetic.

Distorted Recordings... Even voice tags. Cannot find Microphone AGC. HELP!

My voice tags are recorded with ridiculous volume. cannot even recognize my own voice. When i record a video with the camera, the sound captured is completely distored too. i was looking for something like a microphone AGC ( automatic gain control ) in the settings tab. but cannot find. any suggenstions?? what should I try?
PS: In call volume is perfect., so it's no a damaged microphone.
Thanks

Adjustable Mic gain?

Myself and a few others are in need of a way to adjust the Mic to speakerphone level while a headphone jack is plugged in.
I have my N1 plugged into my car stereo and the sound quality is great for navigation and phone calls but people cant hear me.
Engaging the speakerphone button boosts the Mic gain but switches audio output from headphones to the tiny rear speaker on the phone.
Is there a solution I have missed? Thanks.

How to increase the microphone volume?

I have already gone through http://www.modaco.com/forums/topic/314939-req-default-audio-gain-settings/ and http://www.modaco.com/forums/topic/319300-how-to-increase-volume-on-headphones-in-omnia-2/ . There they explains about auto gain control. It was all a head ache. What I want is simple. When I connect my "headphone" (no headset), I use to talk using my phone's inbuilt mic. But my voice becomes feeble comparing to the normal talk without headphones. The other persons are able to listen to my voice in less clarity compared to normal talk. I want to increase volume of mic (not speaker) when I connect headphone and talk. There is no problem with the speaker volume. Auto gain control setting is not there in the settings, and is accessed through code *#0002*28346#. How can I increase my mic volume alone?
Thanks in advance

Bluetooth call quality

I find the in-call sound quality very low when the phone is connected to my car's bluetooth integrated system. The other person can hear me normally, but I can't hear them very well. It's like they are talking through a pillow. It worse when I am in a noisy environnement (for example driving on the highway). However, the sound quality is perfect when I hold my phone to my ear.
So far, I've tried : enabling/disabling the "noise reduction" and/or the "personalize call sound" options. The issue is present whatever the ROM (5.0) and modem used. I've also tried mic-gain mods described in this thread, but it seems that it doesn't affect the in-call sound.
Would you see anything else I could do to improve my sound quality over bluetooth?
The solution is to add in the build.prop, for rooted phones, ro.bluetooth.request.master=1
This will remove the Bluetooth skips.

Intel Joying users, What can I do to improve MIC quality?

During BT Calls, noone can hear me whatsoever. Even when Im not moving they say I sound very distant. This is with or without the external MIC although its slightly better with it, its still unusable while driving.
What did you guys do to improve MIC audio quality?
i'm cut out wires to int mic (and several guys too). Both mic work in parallel mode, settings is no matter. Ext mic alone work perfect. My unit is JY-UM135N2
