I'm hoping I can get some answers here about this. I have a Kenwood bluetooth head unit in my truck. I like to use S Voice to text, play music and other stuff without touching the phone while driving.
My issue is if Bluetooth is on and if I say Hi Galaxy then say Play Music it acts if it doesn't hear me. If I turn off bluetooth connection between the Note 3 and head unit then say Hi Galaxy then play music it hears me fine and plays music.
I was thinking maybe the mic pickup wasn't cranked up enough to hear me on the head unit. On my head unit I have a setting for Mic Gain. Is this suppose to increase sensitivity for the mic to hear more clearly? It was set to 0 but I cranked it up to +8 and then tried it again with no result.
On the sound bars, below the microphone button on the S Voice, if sound is picked up it will move up. It never moved so it's not hearing me. Now if I banged on the top of my dash with my fist the sound bars move and shows it is picking up sound but it has to be a loud bang to a point I feel like I'm gonna cracked my dash if I keep on doing that.
I can't tell if the issue is my head unit or the phone itself. Bluetooth volume is cranked to the max on the phone.
Do bluetooth head units have built in microphones? I would think they do otherwise it would be a pointless head unit and pointless to have call button functions on the head unit.
Anybody have suggestions?

Nevermind. After looking over the manual to my head unit I somehow skimmed over the microphone part even though it came with the head unit. I have no clue why I didn't attach it and understand the point for it was to communicate hands free or else the person would not hear me.
Had to take the unit out and install it and it works perfectly now.

These systems are well known for their mic troubles and I have taken this up with the manufacturer. There is a post that I have seen somewhere in this forum that details a hardware fix. From what I have gathered, anyone brave enough to attempt and has accomplished this fix has not reported any issues; great for the electricians out there.
I do work in the computer industry, but identifying electrical components and soldering is not something I am too confident with. The manufacturer did however, send me an updated update.img file in response to my mic issues. I've installed this and it made some improvement, but nothing so significant that I have actually started using the mic. It also has a new wallpaper and noticed that the default apps have been updated, but not sure how?
Anyway, I've just had a bright idea! I've tried improving the mic by using various bluetooth mics, various external mics that plugin into the mic jack, using the internal mic and manufacturer software update. All make very little difference, but has anyone actually tried using a USB mic?
I don't have one to hand and don't really want to buy one if this doesn't solve the issue. Would drivers/android recognising the usb device be an issue? Hoping someone has had a go at trying this out or can try it out if thay have a usb mic?
Shame no one replied on this one. Did you end up trying a USB mic solution and did it work out for you?
Yeah... Haven't tried it yet as don't want to buy one if it doesn't work. Your reply to this thread would have bumped it back to the top so may still get a response Im hoping
According to this link http://liliputing.com/2012/09/using-skype-on-an-mk802-android-4-0-mini-pc.html, a microsoft lifecam vx-700 with built-in microphone was found to be working on some android devices. The question is whether our firmware would work too. And whether there would be a way to simply disable the built-in input and only route the external usb sound in. It all feels like its probably too much to ask....
OK so I tried a cheap usb webcam with built in microphone to see if it would make a difference. The webcam seems to be working fine for video, was instantly recognized by android and showed video, but sound is still the horrible mess coming from the internal mic. I doubt that a dedicated USB mic would be any different.
Thanks for checking... you saved me some time at least.
Could it be when using an internal mic + external at the same time that can cause this kind of trouble? That is what it seems when i read around forums.
have a look at this, maybe it helps:

I simply cut the internal red wire to mic and installed external mic again and the problems have disappeared. I have been told there is a slight echo but that may be fixed by changing the BT firmware from default.
I think the mic location on the HU is excellent and we don't really need to route an external mic somewhere else. How about just trying to desoldier the old one and try to locate a high quality one and soldier a new one ?
Fortunately I am lucky and my internal mic works great.

Lucky you, though to be fair without an external mic my internal worked, just not very well. I have read somewhere that soldering to the internal connections had issues but not sure why, it cant hurt to try can it?

Shouldn't be a tough solder job.
Just make sure to use a solder sucker to remove old mic and you should be fine.
Guys,
I have the same problem with my android car navigation system.
I have a Note 4 and an android car navigation system in my car (with built in wifi and Bluetooth (BT)). The microphone of the car navigation system has a very low quality, it is almost not working/usable. I would like to pair my phone to the car system in BT but would like to disable the built- in microphone of the android car system and use the note 4's microphone by default and hear the sound of the person who is talking to me on the car speakers.
Is this possible? How? Do I need to use third party apps ?
Many thanks in advance
So frustrating... Anyone have a fix yet?
Android head unit mic barely picking up.
Why have they not fixed this issue?
So frustrating. Got everything all hooked up and straightened out except the daggum mic. I just bought this android head unit (9.0) and the person on the other end of the phone call can't hear me. So I plugged in the external and same. They can barely here me when I am screaming into it.
I have got to get this fixed.
Anyone found a solution yet???
Find out how to get into the engineering menu of your HU, there you can adjust the mic gain. Also have a look at this thread for other ideas.
did you fix it?

I improved the level of my mic built-in with th MTK enginerring app. hardware test and changing mic volumen in normal mode, headset mode and loudspeaker mode, but it is not enough when engine is working. I will try to solder and external mic to the pads of mic built-in. I think that it is problem of software filtering because when engine is off, sounds doesn't rattle, the volumen is not to high but the comunication is steady, but when i start the engine, conversation gets cuts. maybe engine sound is interfering with the mic built-in mic. I will update progresions.
8227L YT9216BJ Head Unit
even my above car android unit has mic problem. it does not recognize the voice commands unless spoken very close to the mic, which is not practical
Also, Bluetooth calls are intermittently heard (with Airtel). But when switched to JIO simcard, works fine.
Please can anyone support with a solution on both the issues

In short for helping anyone that has the same problem
I have a Bosion D6 android (android 10 version – 4 gb ram 64 storage, 8-core) head unit on my Ford Focus mk2.
Everything was perfect expect the microphone, even after I installed the external mic that came with it, the sound was poor and my listeners’ complaint that the quality of the conversation was not very good.
Read tons of stuff here and elsewhere so I decided to spend some money (around 20€) and bought a Sony microphone XA-MC10 to replace the Chinese original (since I have read some good reviews and you can find it in your local market also)
The difference was more than noticeable and everyone now listen to me perfect. i test it myslef through the sound recorder app and it seems like going from say 64kbits/s to 146kbits/s or more.
I don't want to open another thread because the problem is similar.
When I connect with iphone carplay, the interlocutor often hears me jerky, I tried both internal microphone and external also cutting the internal one to exclude it but nothing.
Using the application "microphone amplifier" and applying the filters instead it feels perfectly, but obviously every time it should start and set, so very boring.
Tried to use MTK Engineering mode to change the mic volume, but it doesn't solve completely.
Anyone have any ideas to try?
Thank you in advance
Did anyone ever find a solution to sounding really quiet to the person your calling? Cheers
Called joying and they told me the audio for the phone bluetooth connection only will come out of the front left speaker on all their units, can anyone confirm this? In my vw the sound while on a phone call comes out of all the speakers. Any car i have ever been in the sound comes out all speakers while on a call, not sure why on these it only comes out one channel if its true.
Thanks to anyone to confirm this.
On mine it comes out the passenger side. I know my Kenwood would allow me to select. I've gotten used to it so it's really no big deal

Yup mine does the same thing and it really sounds bad. It comes out of the passenger side and middle dash speaker, but mostly just the tweeters....At highway speed I cant hear half the call.....I am hoping to find a way around this.
Oh wow OK. I had an idea u had a spare Bluetooth speaker laying around and I can use that in the car but it basically defeats controlling the audio from the dash. This blows my mind how bad the audio is in these. Now is that speaker out or rca out on yours?

No, my current set up is still using the factory wiring harness. I havent had a chance to get my amps and trunk all set up for the RCA outs yet. I am hoping someone smarter than me can figure out a way to change the phone audio output settings.....
I am pretty sure it could be done with alsa mixer but I have no clue how to use it to route audio in Android it's very complicated and zero instructions.

It really is a shame. The phone app is just sad all the way around on this unit. Not having a Favorites list is a another big downer.....and I dont know if yours does it at all, but when I am on a phone call I cannot access anything until the call is ended. Everything gets grayed out even when I minimize the call option on the bottom of the screen....I am pretty sure that is just a bug in the software that will get fixed in an update
I don't have a unit yet myself but at this rate it may be only good for controlling the phone but for that matter I can get a separate controller for that.
On my Joying it does this as well, all of the audio comes out of the front passenger speaker. However it doesn't sound bad. It gets very loud, and I can make and receive phone calls fine. The sound is mono as opposed to stereo, and that does sound weird, but I have no issue hearing calls.
Can people with a non-Joying unit chime in? does it do the same one speaker thing? or is that Joying specific?
In the old days this was common practice so as the speakers didn't cause feedback with the microphone which was most commonly mounted atop the drivers pillar. So the opposite speaker was used for audio
I have a Funrover head unit since almost a week and I have the same issue, sound is coming only from front speakers which make the call over bluetooth just a hell for me.
I barely can hear the caller specially while driving
this is a nightmare !!!
Sofia units use both front speakers.
All PX5, no matter Joying or other units, only use one front speaker

Ok thanks, but that being said, is there a way to remediate to this ?

I don't know. It is already going back to the PX3 models. Loads of topics written about it in the mtcb/d forums. It is best to search there.
phone audio is mono anyway, so I guess they just route it to one of the boxes.
So I installed one of the Android radio's in my car over a year ago. Its been amazing so far. The only problem I have with it is during a bluetooth call, whoever I'm talking to hear's an echo coming in on there phone? So whatever they are saying, it gets echoed back to them. I don't hear the echo at all. I'm thinking that maybe the factory microphone and mic built in on the radio are both picking up the words and thus echoing it back to the person. Any thoughts? I'm considering pulling the radio out of the car and opening it up and de-soldering the wires running into the mic that's built in and just running them to the factory microphone wires directly at the head unit. This way I know for sure only 1 microphone is being picked up.
How is the sound quality through the internal mic on your after market head unit? Is it acceptable? Can the person you talk to hear you good enough?
Which unit are you using?
I'm using it without problem, anybody's can heard me.

Cool, thanks. What unit are you using?
Because i've always thought built in microphones are crap and unusable. Obviously i'm wrong.
Anyone else give their thoughts?
Hi,
my internal mic is absolutely crap, nobody understand a word. My unit is a Naviskauto C0255. Newest andoird from booroonbook installed. I was not able to get the external to work, i posted this already, waiting for help. Is far as i know there is no chance to deactivate the internal mic and as long as it is not deactivated, the external will not work. they do not work together, 100%sure, even if other tell you they do!
That's why i started this thread.
To understand how big this problem is.
Imagine that you buy a head unit for bluetooth calls and it doesn't work nomatter if you use an external mic or not. Absolutely frustrating and the producers don't seem to understand what we want.

I found this thread:
http://www.autopumpkin.com/forum/viewtopic.php?f=3&t=171&sid=7db8f39bd1e4fbc8faedd1637802d486
The pumpkin is the same as my device. The user called "Jammy" is a stuff member from Naviskauto. As you can read, they have no idea...they sent new external mics to the people but this, of course, doesn't solve the problem. In the end (at page 10) "Jammy" gave up. One user wrote that we have to cut of the red wire of the internal mic band then the external will work. i am not sure if this is the right way...
i only used the internal mic on my Joying for one call, then I hooked up the external mic, and since I got it hooked up, i never felt like tearing open the dash again to try it.
However I was told both sound ok, just that I was louder on the external mic. I would say 75% of the time people say it is fine. However I dont make a lot of phone calls, and I drive a Jeep, which tend to be noisy
Excellent.
Anyone else that can fill in?
Per mtcb thread, the same mic issues exists as almostevery cheap chinese head unit, including the wince units. The solution is to physically and electrically disconnect the internal microphone and connect a quality external microphone. Forget the cheap Chinese external mics and source a local lapel electret microphone. The difference will be night and day! Installation is important too - suggest mounting on steering column or (best) pointing back toward driver near rear view mirror (window acts as a parabolic reflector.) Keep away from sides/side window to minimise road noise.
Mine is fine up until I'm at maybe 70+mph then it's echoey
I've just bought an external that I will fit which will hopefully improve it...I have been able to use it fine for 3/4 months though
