I found a description of the cable. Interestingly, the document refers to four microphone cables instead of two. Fortunately, I have a cable finder, so if everything goes well, I can easily find the other end of the microphone wires near the head unit.
[Android Head-Units] tolisz78xda:
This is very interesting also for me. I have a Ford fiesta 2010 with own Bluetooth and I am thinking of using the original microphone but I cannot find the cable of the microphone on the original Bluetooth module.!! This diagram is for what model??
[Android Head-Units] marekk84:
Here is the link. Please check the website to see if there is any information about your car model. By the way, I have a 2017 Ford Focus MK3.5. I'm not sure exactly, but apparently, this wiring is common for many Ford models. However, I think I'll only be able to confirm it when I connect my cable finder to the wire and the device signals on the other side. I managed to find out that one of the wires of my microphone is yellow-green and the other is either black or blue. It will become clear tomorrow during daylight, but I won't be able to deal with it until next week because my schedule is pretty busy. By the way, I found another wiring diagram, but it's in a different language, so it's difficult to navigate through them.

[Android Head-Units] tolisz78xda:
Thank you.! In my car I found where the cables are.! They are at the Bluetooth module harness and are yellow and black cable..!
[Android Head-Units] marekk84:
When you have successfully connected to the head unit, please let me know what the result is, because I am curious whether it is worth pursuing.😁
[Android Head-Units] tolisz78xda:
I would have done it if I had a male 3,5 mm jack.!! The only it’s not clear is the mic+ and mic - cable.!! I suppose that the mic+ is the yellow that connects with the red on the mic.!! Where we can find that?? If I connect the cables I believe it will work.!! I don’t believe that Ford triggers with something the mic to work.!! I suppose it’s a simple connection..!!
[Android Head-Units] marekk84:
It would be good to have an engineer from Ford to ask in these cases. What I can say, if my memory serves me right, is that the microphone impedance of mine is 16.3 kohm and when I started the car, I measured 0.3 volts on the microphone side. I'm not enough of an expert to deduce anything from this. If I can't figure it out, I'll directly solder the Ford microphone to the position of the head unit's internal microphone, but I'm trying to go for the first solution, to make it work from its original location on the factory cable.
[Android Head-Units] tolisz78xda:
I will connect it to a 3,5mm male mono jack and I will connect it as an external mic .!for sure the quality will be better. If still I am facing serious problem with the internal mic a will desolded it.! Already with a more expensive external microphone I tried and the quality was much better. I believe that if you measure any microphone you will find some voltage.! It’s a need to make it work I suppose..!!
[Android Head-Units] marekk84:
My plan is the same, but due to lack of time, I can only do it next weekend. I will try to do everything in one disassembly, connect the external mic and desolder the internal one, as the car is in daily use. I will also try to make a tutorial about it, so that it can be easier for others in the future. By the way, it is also possible to connect a stereo jack plug, there is information on the internet on how to convert it to mono. Alternatively, you can cut off the jack plug from an external mic sent to the head unit and solder it to the appropriate wire in the cable harness.
[Android Head-Units] TorstenH:
Usually red is + so I would simply give it a try.
[Android Head-Units] tolisz78xda:
Same as me..!! I can only do that during next week..!! I found that under the dashboard behind the glove box there is a connector for the original mic..!! So I will not modificate any cables of the cars harness..! Only I will disconnect the connector and I will install two female clips on it .!! When I do that I will upload also photos..!
[Android Head-Units] tolisz78xda:
Οκ.I will try it.!!After all is not a risky situation..!!
[Android Head-Units] tolisz78xda:
I had time today and i tried the original cars mic I connected to a stereo jack as a mono and I plugged it but it didn’t work..!! When I spoke to the mic nothing happened..!! I don’t know if it was wrong connection on the jack or it needs some voltage to play the original mic.!!Then I isolated the internal mic I installed a audio recorder and I tried.. Again at speed over 60km/h I hear a lot the cars sound..!! My internal mic is solded directly to the chip not with cables..!!I am afraid to desold it .It’s possible to damage the chip?? If I tell Junsun to send me another chip to install will need new modification or it’s plug and play?? Because in the past they answered me that need adjustments..!!
[Android Head-Units] TorstenH:
A test of the external mic makes only sense after removing the internal mic.

But a multimeter to check connection between OEM harness and OEM mic may become helpful.

The small board is only responsible for background illumination of the buttons and the internal mic.

You could disconnect the ribbon cable to do the test. Nevertheless ribbon cables can be tricky to remove and connect.

It's absolutely no problem to desolder the mic if you apply some solder to the tip of the soldering iron for good heat conduction. But don't use such a cheap solder gun from the hardware store.

What should be adjusted on the circuit board of it's the same type?
[Android Head-Units] tolisz78xda:
I checked the harness and everything was ok about the connection.!! I don’t know if the oem mic needs something else to work.!! I have seen videos for aftermarket radios they replace the own mic and install aftermarket at the same car potition ..!!
[Android Head-Units] tolisz78xda:
The small board also has the reset button..!! To tell you the truth I believe that is plug a play no need for adjustments..!!
[Android Head-Units] TorstenH:
You may need to pull out the OEM mic and check if it only has two wires. With a multimeter you can check if those wires are the ones you connected to the head unit.

After that you could replace it (if needed) or test with the desoldered Junsun mic.
[Android Head-Units] tolisz78xda:
I have already checked it.!! It has two wires and I have also check with the multimeter and ensure the cables goes to the Bluetooth module..!! To those cables I connected the jack ..!!
[Android Head-Units] marekk84:
Did you test it with the external microphone sent to the head unit? Does it work through the 3.5 jack?
[Android Head-Units] tolisz78xda:
Yes I tested it via the external 3,5 jack but it does not work..!! Maybe it needs power..!! I don’t know..!!
[Android Head-Units] tolisz78xda:
Guys I don’t know if there is another topic but I want you help..!! At the multimedia screen appears an icon like a camera . Is not stable but I can move it with my hand at every point of the screen .!! I cannot disable it .. Any help?? I will attach photo.

Another is I have installed an ahd 720 camera witch turns into cvbs when I cut a white cable.!! The problem is that I cannot play ahd720 even though make the adjustments but only cvbs mode.!! See attached photos..!!Any help??

Why are you asking in a threat regarding microphone issues below questions?

https://xdaforums.com/t/junsun-v1-p...0-canbus-settings-issue.4203371/post-84575975

Check 8878 factory settings, section Others. At least there is an option to switch between CVBS and PAL. If you hear unit is not supporting AHD you need to cut the wire.

But I already seen another thread discussing this topic.

Searching via Google by adding the keyword xda may provide better results.
[Android Head-Units] tolisz78xda:
Ok thank you very much and sorry for writing other subject here..!!
[Android Head-Units] tolisz78xda:
Regarding the mic problem what I did and I have very good quality was to isolate the internal mic when I opened my multimedia , I ordered a Sony better quality mic and I placed over the mirror at the centre of the car ( at the interior light) . After that they told me that they hear me loud and clear with a very low noice of my car.!! But I can communicate well until now..!!
[Android Head-Units] Serg039:
Hello!Please tell me what model of Sony microphone did you buy?Thanks!

[Android Head-Units] Serg039:
Hello!Thank you for the information about the microphone, unfortunately we do not have it on sale.I will look for an alternative.Thanks!!!
[Android Head-Units] marekk84:
Over the weekend, I managed to test the microphone. I gave up on the original Ford microphone because it would require me to dismantle the car to such an extent that it simply wasn't worth it. So I used the external microphone that was sent with the head unit.

My first attempt was to disconnect the internal microphone board, which can be seen in the pictures. The microphone is so small that I didn't attempt to desolder it for now, but I think a heat gun may be required instead of a soldering iron. Luckily, the 3.5mm jack connector doesn't produce any sound when the internal microphone board is connected or disconnected. The external microphone works because it can be used when connected to a computer. Everything is properly connected to the back of the head unit. I'm currently at a loss as to what the problem might be.
[Android Head-Units] TorstenH:
In case you will become issues because of the internal mic you could cut the traces on the board. E.g. by using a Dremel, a knife or a screwdriver. But this is not easy to undo so disconnecting the board (if required) is the better approach for testing.

Maybe I already asked if you installed such a recorder app on your head unit

Audio Recorder - Apps on Google Play

Audio Recorder with custom path selection and editing, no ads, open-source

play.google.com

to check if the mic is working basically. This may help to identify the root cause.

After switching my phone I had problems with Bluetooth calls, too. Finally I figured out that the root cause was the phone and not the mic or the head unit...
[Android Head-Units] marekk84:
Yes, I tried such apps. Unfortunately, the result was the same. There was no sound from the external microphone when I disconnected the internal one. And when I reconnected the internal one, it was the only one that worked. The external microphone was not present under any circumstances. I only use Apple CarPlay on the head unit. The result was always the same: the internal microphone worked, but poorly, and the external one was always silent. I don't think the phone is faulty because it didn't work with that either, and the microphone testing program was also silent. Could there be a software switch to activate the external microphone? This is a Jansite S10 4/32 head unit with Android 11.
[Android Head-Units] Jubideme:
Hello good evening, I am new to the forum. I have already introduced myself and I am going to expose my experience with the microphone my junsun v1 pro 6/128.

To me with the internal microphone I hear me but something lower. I have tried to change the gain values as they put in previous post but I don't get that option in the engineer menu, it comes out all blank (there is a photo of a colleague who gets exactly the same) and you can not change any value.

Well I recently bought an external wireless microphone (I just found this amazing item on AliExpress. Check it out! 5.35 69% OFF | Wireless Lavalier Microphone 3.5mm Bluetooth 5.0 recording Mini Microphone for Dj IPhone Android Live Broadcast Gaming Phone Mic

https://a.aliexpress.com/_EubX7Ct ) and without removing or touching anything from the internal microphone, in my calls tell you that I can be heard perfectly, no background noise or bass or anything. Only that the PERSON talking to me can hear her when she talks to me... which is more annoying I think....

Can you tell me why this is and if it can be removed somehow? I understand that the microphone reproduces the conversation that comes out of the car speakers.... Right?

Thanks for any help.
[Android Head-Units] Lukas69MN:
HI

Maybe you have a bit high volume for your speaker or the mic is positioned in a bad position where "listen" the audio played from speakers?
[Android Head-Units] Jubideme:
Hi, I have the volume at a normal level, so that I can hear it clearly and it is not heard outside in the street.

I have placed the microphone where the interior courtesy light is. In my car the original standard microphone is also tucked inside the light console light fitting as I've read, so the distance to the speakers shouldn't be a problem.

I just put it outside and clamped it with the clip it comes with....

Yesterday when I was testing it I got out of the car and made a call with my mobile to my daughter who was inside the car connected to the Junsun bluetooth and I heard her perfectly without noise or change of volume or anything, but when I spoke, while talking I heard myself, a drag we go .... 😅😅, I'm going to change my microphone to see if it's a wireless thing and I'll report back to you.

The microphones I have (I bought 3) are all omnidirectional... Is that something to do with it?

Anyway most of the ones they sell are omnidirectional.... 😓😓
[Android Head-Units] Serg039:
Test method: Press and hold the disconnect icon on the Bluetooth mode interface for 3 seconds and then speak to the machine (this is the microphone test method).
[Android Head-Units] romenard:
They wire the jack for the external mic wrong. They use a stereo headphone jack and wire the connections to the two end tips and leave the ground without any connection. I cut them off and solder a a normal mono jack into its place and the factory external mic will actually work afterwards.
[OnePlus 7 Pro Questions & Answers] jluva420:
Hello I'm considering getting this phone. I researched and found that this phone model 1917 is the right one for Verizon it has all its LTE bands and I could give a **** about Wi-Fi calling or visual voicemail or video calling I have apps for that. My big question is about the hot spot for people using this phone on Verizon.

Do you have to do anything to get your hotspot to work properly the reason I don't buy phones from Verizon is I'm on the grandfathered unlimited data plan meaning I don't get throttled after using a certain amount of data it's only $10 more a month than their so-called unlimited plan offered now.

If I switch to a Verizon brand phone they will make me sign up with dere new data plan which only offers 30 gigabytes a month and I would burn through that inside of a couple days.

This is the reason I've been sticking with my HTC u12 plus. The native hotspot on this international phone works right out of the box since it's not Verizon limited software. I just wondered does the hotspot work flawlessly?
[OnePlus 7 Pro Questions & Answers] tech_head:
HI,

I have a 7 Pro but I am on the newest plans; Get More Unlimited.

I got rid of my grandfathered plan because there was no benefit for me and the new ones are cheaper.

There is a provisioning check on some phones. If you root you can bypass the check.

[Google Pixel 4 XL Questions & Answers] kowy3:
Hi folks

I have an MSI laptop with a USB Type-C port, I have never really used it but yesterday I wanted to charge my Pixel 4 XL from it. I had the original Type-C to Type-C cable in my bag but it doesn't charge my phone when the other end is plugged in to to Type-C port on my laptop.

Today I brought an Anker Type-C cable with me, but that doesn't work either.

Both cable charges my coworker's Galaxy S20 from my laptop.

I tried cleaning my phone's USB port, but no luck. My phone charges from Type-A to Type-C USB (although very slowly, 10 hours to full charge) or from the wall adapter fine.

Any suggestions?

Thank you

[Google Pixel 4 XL Questions & Answers] kowy3:
I got an MSI GV72 8RD, but it is so strange it charges my coworker's S20 without any issues. That makes me believe the issue is with the phone, not the laptop/cable.
[Google Pixel 4 XL Questions & Answers] EeZeEpEe:
It's possibly device specific for whatever reason. I plugged my phone into my Pixelbook Go and of course it works with it. Even says fast charging. I do have USB-C inputs at my job that I can try to charge with today.
[Google Pixel 4 XL Questions & Answers] kowy3:
Yeah that is possible, I know Type-C uses some kind of negotiation between the phone and the "charger device" what voltage the phone can take. All I can think is my laptop can't provide the appropriate voltage for the Pixel 4, that is why it doesn't charge. However, I am not sure if a Galaxy S20 got wider tolerances for charging voltage, it just seems odd that it charges one phone but not the other.
[Google Pixel 4 XL Questions & Answers] bobby janow:
When I first got my Pixel 3 the same thing happened on my HP Envoy. I tried rebooting, different cables, everything I could think of. All of a sudden one day it started working and I have no idea why or what I did to make it happen. Definitely try another cable after rebooting both devices and by all means stick with it. One day it's gonna work. lol
[Google Pixel 4 XL Questions & Answers] kowy3:
Update:

Right, it seems it might be the laptop that is causing the problem.

I am not quite sure why it wouldn't charge my Pixel but charge a Galaxy S20.

Today I connected my phone to a new Dell Latitude and it rapid charged it straight-away with the same cable. This confirms that it must be something with the Type-C port on my MSI laptop.

Fastboot version 30.0.4-6686687

Trying to temporarily boot TWRP recovery image twrp-3.4.0-0-lake.img on my unlocked Motorola Moto G7 Plus.

Phone is connected via USB Type-C to Type-C cord from the box to my laptop running Linux (Manjaro 20.0.3) Live USB system.

When I run ./fastboot boot twrp-3.4.0-0-lake.img or ./fastboot boot boot.img (same file, renamed) with and without sudo, it always gets stuck at Sending 'boot.img' (30080 KB) doing nothing.

Bootloader logs section of fastboot mode shows only cmd: download:01d60000.

The PC I use now is the only PC that helped me to actually unlock the bootloader. Other PCs I have were not able to send correct fastboot commands (for example, oem help transformed into oem helpersion, and oem get_unlock_data cut to oem get_unlock). Those PCs had regular USB Type-A 3.0 ports, so I had connected them to my phone with corresponding 3rd-party cable. It might've been of insufficient quality though.

All files are located near to the root of extrenal SSD connected to another Type-C port, so the absolute paths to TWRP image and fastboot executable should not be too long.

Type-C cords I'm using now are new and OK.

Motorola doesn't distribute Linux drivers for their devices.

What else could be wrong here? Please help. Any advice is appreciated.

Will update this post later with my own findings as well for people who could stumble a similar problem.

Update 1

Tried fastboot boot boot.img on another PC. It is also running Linux (Ubuntu 20.04). Connection is from Type-A to Type-C. Wire is good. No noticeable changes. Main issue persists.
[Moto G7 Plus Questions & Answers] Adai0:
What does "fastboot devices" say? Try running the commands with root and with a different USB cable.

Edit: It should work. I just bootet TWRP 3.4.0-0 several times. I used Fedora Linux with android-tools-20180828gitc7815d675-4.fc31.x86_64 which includes fastboot. BL on device is MBM-3.0-lake_retail-38523c9-200214
[Moto G7 Plus Questions & Answers] AdiG15:
Any further update on that ?

Same happens with my device (motorola one power).

The bootloader logs shows "cmd: download:<8 letter hash/code>"

And cancelling the operation doesn't do any harm, just your next command will fail with

"FAILED (remote: 'unknown command')", and bootloader logs will print an empty line starting from cmd:.

Did it work later on, what change did it require if you remember a bit ?

Update: The OP has put the question on reddit:
