Hey Pedaaa,

again, thanks for your help. I got it to work: I bought an pioneer mono mic from amazon, i soldered out the internal mic completely and soldered the pioneer mic. Now it works. Although i have an external 3,5mm jack for external mic i think its a blind jack! If you have a look on my pic above you see that i have 2 usb 3g cables and the external mic cable, BUT on the pic they do not write something about an external mic so i guess i don't have one (no connected pin inside my hu). The user you mentioned has the newer model of C0255, i have the 2015!

If have no idea why soldering the original mic didn't work two days ago but soldering the pioneer did. Maybe it was my fault. Now the call connection is much better but not perfect. I hope i can improve this quality with apps oder updates from Booroondook one day but for the moment i am happy.

Can't say how thankful i am for your help!

Mic mod for WITSON unit (KYD).

Attached photos.

hello, i have Witson A7047 - RK3066 KLD.

Is the best solution cut the intrnal mic and use the external?

Thank you
[MTCB Hardware Development] marchnz:
Yes, in my experience can be universally done in any chinese double din, android or wince units.

Note if you are able to, disconnect mic as close to main board by cutting track or lifting 0 ohm/jumper. This is to keep noise down to a minimum.
[MTCB Hardware Development] csfound:
Thank you very much, i will try to make this modify :)

Hello,

I bought KLD HU and cut off internal mic wire completely and plug in external mic as usual. The bluetooth phone call quality improved significantly, but google ok, voice command and even voice recorder won't work anymore. I did confirm scratching the external mic while on the bluetooth phone call and the caller heared the heavy scratch sound, so I believe external mic is working.

Can someone please give me advice?

Thanks,
[MTCB Hardware Development] celiocalves:
I have read all the pages and I'm tempted to cut the internal mic wires (i'm already using the external mic).

I have a KLD pumpkin HU and my problem with phone calls is that the person on the other side listen too low my voice, i need to speak louder and near the external MIC.

Cutting the internal mic wires will solve that problem?

Thanks

Hello. I have a radio XTRONS TD626A. Also has a problem of poor quality of calls by BT. I do not care for the voice commands. As I understood enough to cut off the internal microphone and enjoy a good reception?
[MTCB Hardware Development] sayborg:
Hello everybody,

I have read ALL the posts and decided to describe my problem. (I am NOT good in electronics. Soldering, unsoldering for me is too challenging at this stage :)

I own a Chinese Android Head Unit (MTCB, Android 4.4) WITHOUT the external microphone jack at the back (the whole is there in the chassis but not the jack).

When connecting the car radio to my samsung smartphone via BT, I can perfectly hear the other person on the speaker but that person can not hear me.

As far as I understand, since I do NOT have an external microphone port at the back, I need to unsolder the internal microphone and solder a high/good quality internal microphone one (please make any suggestions so that I can buy it on amazon or ebay).

1) Some people are suggesting to connect an EXTERNAL microphone to the internal microphone pins. Why external and not replace the internal microphone ?

2) If I only cut the internal microphone red cable, will I not be able to use my smartphone's microphone to make phone calls and hear the sound

from the car speakers ? That would be the easiest fix for me since I am not good in soldering/unsoldering. Will this work ?

3) Please suggest me a good quality internal (or external) microphone I should buy and replace.

Many thanks in advance

Update: I paid 60€ to a autoradio repairer, he did the modification + added an external jack and microphone, now they don't notice that I am calling from the car.. :) Thank you for the information...
[MTCB Hardware Development] pakidermo5000:
Hi,

I have the same board as you and wanted to do the mic mod. Did you notice any improvement?
[MTCB Hardware Development] allan360:
Good question, why not just replace the internal mic?
[MTCB Hardware Development] anonaisu:
Found one of solution for KLD.

Here are procedures what I did;

1. Cut off Internal mic entirely. Use only external mic.

Improved phone call, but still noisy voice from HU to the caller.

Voice command not working.

2. Unplugged external mic and soldered to the place where the internal mic were.

Still noisy phone call.

Voice command working.

3. Changed driver from WQ-BC6 to WQ-BC6b.

Exllent phone call, no more noise.

Voice command working.

Thanks,
[MTCB Hardware Development] Eljupo:
Will removing the internal mic encrease Thema volume of the external one? May voice volume in hands free calls is way too low.
[MTCB Hardware Development] itsmewajid:
I recently bought this one

https://www.aliexpress.com/item/3G-...32723495887.html?spm=2114.13010608.0.0.DPRJ82

internal mic quality is very poor this one has external mic slot

What should i do?
[MTCB Hardware Development] allan360:
Use external mic ?

[MTCB Hardware Development] itsmewajid:
But i read somewhere here if you connect external mic there is no difference unless you remove the internal mic.
[MTCB Hardware Development] allan360:
Well, both microphones are active when you connect the external mic, the internal just dont shut off. If you dont like it you can just disconnect it, its not that hard...[emoji106]

Hello,

I have a pumpkin unit (model s07 for ford focus)

MTCC-KLD6-V2.97

Will this solution(removing internal mic, add external mic) work for my model?

Thanks in advance.
[MTCB Hardware Development] Johny DJ:
I know its a bit old post but anyway will try to ask...

I have similar board like you, just REV. 3.4. Can you tell me what you did at the end and what was best for you?

Thank you.
[MTCB Hardware Development] Lyhaku:
Hi, in the end i just cut the frontal mic and connected the external mic. Now the quality of bluetooth calls is better, no more noise, but the call quality is still poor. There's always a small delay, and the person I'm calling complains that my voice sometimes is intermittent. It's usable, before it wasn't.
[MTCB Hardware Development] Johny DJ:
Thanks for that info... So you didn't do the MIC mod, just cut the front MIC and connected external one to the jack? Was wondering if cutting the front one and also connect externall mic to +mic and -mic on board and shortcut the capacitator will amplify the mic...

I also tried to put the preamp before the external mic but I just got noise all over so it was useless...

I also tried to set BT: WQ-BC6B in settings and increased mic quality and also lowering noise, so you could try this one, if you haven't yet...
[MTCB Hardware Development] Johny DJ:
Yes I have no problem with soldering as I am electrician :) I tried the folowing:

- I removed internal mic and made it external so i moved it closer to me (all I got was 2 seconds delay, like you have, also tried diferent mics still the same volume)

- I also solder directly to BT board MIC + and MIC - but external mic is not working (now I don't know if it worked once or not, or it stopped when I upgraded MCU KLD6 to KLD9 - strange)

- So at the end I'm using just internal MIC which I extended outside

Will also try downgrading MCU to KLD6 latest and try, because I also have external jack connector for external mic but now I'm confused if ever worked.

I installed Modern Rec Forge Pro and check which mic is working and I figured out that just internal one...

(if I have both connected internal and external one, just internal is working, also when I connect directly to MIC + and MIC + nothing change)

Do you perhaps know what I have to cut and solder to BT board, because I don't have capacitator C32 near BT board...?
[MTCB Hardware Development] Lyhaku:
I don't know what to cut because I don't have the C32 like you. In the same position i have another component but i don't know if it's the same capacitor only renamed. Btw I also testet my solution with many recorders and the sound is crystal clear and good volume. The problem is only the bluetooth call. Let me know if you manage to solve it :)
[MTCB Hardware Development] Johny DJ:
I know its a bit late, but can I ask you which setup you have because dsa's removed all his posts and I don't find anything else to imrove mic quality or volume...

Thanks.
[MTCB Hardware Development] alexandros75:
Hello,

I have a pumpkin unit (model s07 for ford focus)

MTCC-KLD6-V2.97

I removed the internal mic (after removing a lot of screws) and then I plugged into the mic slot the external mic given by pumpkin.

The quality when the car is stopped is acceptable but when the engine is on and the car is moving there is a lot of noise.

The external mic's wire runs a big distance until it reaches my car's roof.

More over, the external mic does not work with Android.

What should I do?

1)Replace the internal mic with a better quality's one?

2)Replace the external mic with a better one?

3)Solder an external mic at internal mic's points?

4)Something else?

Thanks
[MTCB Hardware Development] Johny DJ:
I did the following from part 3) Solder an external mic at internal mic's points and replacing the mic with better one.

And I also connected external mic directly to the BT board MIC+ and MIC- but I did not get external mic to work, probably because I upgraded MCU from KLD 6 2.97 to KLD 6 2.98 to get the ability to store radio stations even if I reset the radio, but I don/t care because now its working and it also doesnt pick so much noise.

[UNOFFICIAL][5.1.1_r28][AOSP_5.1.1]DIRTY UNICORNS 9.8 FOR XIAOMI MI3/4

[IMG="DIRTYUNICORNS"]https://i.ytimg.com/vi/RBzCI_z3EEU/maxresdefault.jpg[/IMG]

Dirty Unicorns is a project that started out with no name. It was a project that was first created based off AOKP back in the early days of Jelly Bean because of curiosity. In the early days it was just a one man show on one device (EVO 3D). Since then many others have joined the project and it has grown a whole lot. We have seen a lot of talent contribute to this project of ours and many of our contributors have gone to help other projects and that is ultimately why we do what we do.

Once Jelly Bean was over, we decided in Kitkat to move to a new base which was OmniROM. While AOKP was fun, OmniROM proved to be even more exciting because it challenged us to see what we could with something different.

With Lollipop, we have moved to an AOSP base with a lot of patches from CAF to make our older devices function as they should. That said it has been an awesome learning experience and is still not over! We are still learning every day and continue to move forward.

Few more things we will say is that we don't accept nor ask for donations. We don't believe in that. Everything that is necessary to keep this project going is out of our own pocket. Gerrit, Jenkins, Websites, Devices, etc.....

We will never ask for a dime. All we do ask is that you search, read and try to enjoy the process with us!!

[Mi 3 Android Development] a.broken.star:
Is the missed call bug solved ? In the last test version of this ROM by Banks, missed calls notifications were not shown, as missed calls are simply listed as recieved calls in call logs. You have to check call logs everytime to see if there is a missed call (call shown as recieved, that you didn't picked up)
[Mi 3 Android Development] sdnavale:
Yes it is...
[Mi 3 Android Development] a.broken.star:
Yes indeed it is solved... i am using this rom right now.. Let me see if there is any other bug...
[Mi 3 Android Development] teodos:
Well i am using nova launcher so it won't be of much help to show you those... For the sound it is very easy to fix any low volume install kernel adiutor and from there in the sound section increase the settings I did this and now the volume Is superb on call volume is also excellent. You can imagine the pure speed and smoothness of this rom until you try it. This is something none rom has.

still confused about CPU label

(Oneplus X E1003) In CPU-Z I see MSM8974Pro-AA (meaning the lowest version of the SD801).

This would mean the ISP = 320 MHz, the GPU freq = 450 MHz, memory interface = 800 MHz (source Anand Tech, sorry I'm not allowed to post links yet, google search term: Anand Tech 800 vs 801).

I see in different usage monitors that the cpu can reach 578 MHz.

I also see the 3D Antutu 5.7 score is ~11000 where as the Galaxy S5 scores ~13500, this is a big difference.

Could someone please:

1) confirm the correct ISP freq and Memory Interface freq of Oneplus X E1003? (I wasn't able to find it in android)

2) explain the difference in 3D performance v.s. the Galaxy S5 SnapDragon 801?

3) confirm (with source) what's the exact version of the SD801 inside?

Kind Regards,

Koen
[OnePlus X Q&A, Help & Troubleshooting] ckret:
S5 has a SD801AC

the OPX has SD801AA-Pro which means GPU is higher clocked

everything else should be equal to SD801AA

I have the same unit its MCU 2.02 though but only certain BT ELM works.... I found on that works fine... I will include more info in my write up....
[MTCB Android Head Units Q&A] agentdr8:
By default, these headunits only recognize and pair with BT OBD adapters that have the name "OBD". I've removed this limitation with the latest experimental release of the XposedMTC module.

It seems that the rotary encoders used for volume and tuning are sometimes susceptible to vibrations/bumps. I've had issues where the volume randomly goes up or down while driving. After spinning the knob up and down a few times it goes away.
[MTCB Android Head Units Q&A] makkan00:
Thanks. I will try it.

With regards to obd, how do I take out the restriction on obd adapters which my unit can use?

Thanks.
[MTCB Android Head Units Q&A] agentdr8:
You can either decompile the MTCBluetooth3.apk and Settings.apk, modify the smali files to remove the restriction and recompile, or you can root your headunit (check out the first post), install the Xposed Framework, and install the XposedMTC module.
[MTCB Android Head Units Q&A] Shagman68:
I have xposed mtc and framework and this is a year later. It still does not see my bluetooth ODB as it is not named ODB. It is named CBT
[MTCB Android Head Units Q&A] agentdr8:
Compatibility also seems to depend on the version of the adapter; the generic ELM327 readers come in many versions. I haven't correlated which versions work and which ones don't, but my adapter, which also shows up as "CBT" is a v1.2, and the override within XMTC does work.

I'm assuming you've already set the XMTC preference to "CBT" and rebooted? Make sure the pairing pin in the stock BT app matches that of the OBD adapter (e.g. 0000, 1111, 1234), and try pairing from within the BT app.
[MTCB Android Head Units Q&A] staticx1:
hey [MENTION=434511]agentdr8[/MENTION] , I've managed to install Xposed, but cannot install the module itself... tried several versions and it still not working on my 4.1.1 Head Unit.
