Hi just received an "EONON" android head unit that I bought on ebay.
It is the KLD RK3188 Android 4.4.4 version with no DVD player.
The unit is great, except for one major issue. The microphone is useless, both the internal and external mic produce very loud continuous buzzing both in phone calls and in Android apps.
I saw some others had some issues similar to this on other units, but I have not seen anyone mention this on this specific one.
Does anyone know of a fix for this?
I have tried a usb mic, but I can't get the device to use it as default.
Any advice would be appreciated!!
Its not an Eonon, they are just re-sellers, its a Klyde unit, they are all the same basic unit apart from screen size and front design and whether they are dual or quad core, read the main HuiFei thread, specifically the first page for a solution to the problem (You DONT want to use a USB mic as it probably contains a sound card so ALL Android sound will be diverted to it).

Thanks for the tip.
I actually was able to fix it by following that solution. I removed capacitor C32 and connected an external mic directly to the bluetooth module.
Phone calls are great now, Android is still using the internal mic with the crappy audio, but it seems like it would be difficult to fix and it works at least well enough for some basic voice commands which is all I need.
Hi
Burnaby BC, is your unit KLD ?
if so can you explain what you did ?
I understand that you have to remove capacitor C32 but what I don't understand is how did you do the second part(connect external mic directly to the BT module.)
thanks

Yes my unit is a Klyde (KLD) unit.
Look at C32, it should be next to the bluetooth module (unfortunately I don't have a picture).
Follow the trace that connects C32 to the input on the bluetooth module.
Once you remove C32, connect the microphone positive lead (+) to that input.
Then connect the microphone ground/negative (-) lead to ground or a case screw.
This will fix the bluetooth phone call audio.

I recently installed eonon headunit. I was able to mirror my s7 edge onto the head unit. I updated my s7 to android 7 and now i cant mirror the two unit anymore.
I can use bluetooth to stream audio on phone to headunit
Hi everyone, I tried searching, I'm very sorry if I missed it. The one we have is the typical quad core, 16GB storage / 2GB RAM unit with Android 7.1 pre-installed, running on a PX3.
We just installed this last week, and we love it, but we have a couple of issues.
I have a microphone wrinkle that seems different than other posts. I don't use the mic much, and right now, I don't want to install an external. The mic clearly works for the bluetooth phone dialer (I put my phone outside the car to verify that the head unit mic was being used), but I get nothing at all for any other app (OK Google, OK Waze, a voice recorder app I downloaded to test, etc).
There had been mention in threads I searched of going into the factory settings menus / independent volume levels, but I see menu options only for adjusting volume levels to speakers (radio, apps, etc), but nothing for the mic. And obviously it's not zeroed out because it works with the bluetooth dialer. I asked the seller (Seicane) and they are looking into it. Any thoughts? Just to be clear, again, I just want to know about getting the internal one seen for other apps (mostly to be able to use OK Google), I know there are options to splice in an external mic... and we'll cross that when we come to it.
Also, we installed into my 2010 VW Eos... has anyone connected the VW diversity antenna lead to this stereo, can you recommend the right adapter, since this is the only piece that does not seem to have been included with the head unit that we need?
The only other thing I'm trying to figure out right now is how to stop it from going to a hazard icon (because I don't have a backup cam) whenever I go into reverse. It sounds like what I need to do is root the device and delete the APK for the reverse cam, or else it sounds like cutting a wire is also an option, I just haven't tried either, yet.
Thank you for looking!
i have a Seicane, 2 actually, the older 6.0 unit and the newer 7.1.2 unit with PX3:

You shouldn't have to splice anything for an external mic? Did it not come with one? there should be a hole to plug in? That being said, I have not tested it without the external mic, but I definitely can get OK Google to work with the External Mic. Next time I take it apart, I'll try the internal only.
as far as the backup came, did you look in Extra Settings? or Factory Settings? I do have a backup cam, so I want it on, but I think there is an option to turn that off somewhere.
Edit to add - I also started a Seicane subreddit:

Hi, I'm sorry, external radio antenna (not mic). The car has something that looks like maybe a twin FAKRA connector? The adapter that attaches to the back of the head unit is supplied for antenna, but it doesn't match that... I see things that look like they might fit on Amazon, though, going to order one ASAP and give it a try.

Hmmm, I might be missing which setting controls this, there doesn't seem to be one related that I can find, although what some of them do seems kind of counterintuitive.
I'm going to go check out your subreddit! Thanks!
The Seicane will included an AM/FM radio adapter for regular radio, but I already had the Metra 40-EU10 Antenna to Radio Adapter:
http://amzn.to/2y2pJln
That one is Jeep specific, is that what you are looking for?

Thank you, we went back in and looked more closely. So it turns out my Eos actually has three different antenna systems, and the stock radio connected to them all in a diversity arrangement and switched between them as needed, apparently. One of them has a single Fakra connector (what plugs into the piece you posted), which is what we plugged into (except that we missed plugging the power wire back into the wiring harness to the CANBUS), but I found several posts related to other head units that said that the other pair of antennas, that are in a twin Fakra connector (two of those plugs side by side) actually works better (but it sounds like it isn't possible to use them all at the same time). So the next step will be to order an adapter from the twin Fakra to the plug on the head unit (sorry, I haven't hit ten posts so I can't link it) and in the meantime I'll see if the missing power wire makes things any better, it sounds like I was using the antenna that I was using, unpowered, when it's supposed to be a powered antenna....

Hey guys so I have an Alfa 159 and bought one of these head units:
Edit i cannot post a link however its the generic A-media Auto alfa 159 head unit which can be found on google
now I was speaking with a friend of mine who explained that the roms are "cut back" and removes some features and full blurtooth control/ support is one of them
I am reasonably ok with computers but never ventrued into any sort of custom android stuff and the extend of my knowledge is " i know you can get custom roms" i hdon't know how to do them or use them etc.
I have some bluetooth modules i can control from my phone in the car (lighting and actuators) but would love to be able to do it from the head unit
Would it be possible to get a custom rom for this head unit and if so any guides at all?
I would like to point i did have a search but honestly i am not totally sure what I am searching for and searching sepcifically for this head unit didnt help.
Thank yoiu very much
It's not so much that the ROM removed bluetooth features as much as it is how the bluetooth module is integrated to the HU. There's 2 system boards that make up the HU. The SoM has the Android system and is basically a tablet motherboard with only a display, audio and USB connection. The MCU provides a USB hub, audio preamp and power amp, connectivity to the car and the bluetooth module. The bluetooth module is treated as a headset controlled through a serial connection with AT commands and this is where the problem lies with using bluetooth with any apps other than the built in ones. It works for ODB dongles so it is possible but if the functionality you're looking for is not already implemented I doubt someone else would be able to add it to the MCU ROM. All I can say is try and see if it works.
Maybe you can try to connect a USB bluetooth dongle the issue here would be Android drivers.

Thank you, sorry for late reply.
A friend of mine figured out with his that it was "nuked" in the software allegadly. the bluetooth module is a generic module but unfortunatly I am not massivly clued up on reflashing roms or even where to start especially on a head unit which is a shame.
My friend unfortunatly has since moved country so I can no longer ask him to take a look
I don't suppose anyone else might have an idea to this?
this comes up often apparently nobody give f*ckall to address this issue.

i know, my radio is great, does everything great. I just want to connect bt to my ham radio and use this as the head unit. and I was thinking about using those bluetooth valve stems so i can see the air pressures in my tires, looks like those wont work either.

Have you considered that these units work for the intended use and if it doesn't work for some obscure use case the desire to solve a problem for single users is limited. To expect others work on an obscure problem for you seems a bit entitled.
Have you considered taking the lead on this issue.
Bumping to see if ANYONE has came up with a solution, maybe an external dongle?
hello everyone ! i am writing here hoping to find some help. recently i bought an Android Head Unit with 8227L, 2gb of ram and 16 storage. The "issue" is that there is an equalizer option in car settings in the "Sound Settings" menu but it is used only when listening to music by bluetooth, usb storage or on youtube. When trying to use spotify or youtube music, the sound is flat, it lacks bass. It's like it's ignoring the eq. I tried different versions of spotify in hope that it will have a built in eq. I looked in android setting in audio at audio enhancements but nothing is there. I will attach some pictures of the unit with different information that might be useful. Thank you in advance !

Sorry to hear about your issues. Luckily, there is a solution and not just to this problem. Check out this guide:
[GUIDE] YT9216BJ !SUPERMOD! - ROOT, Viper4Android, TWRP, Custom UI, brick recovery and more
It does not look like the original rom. It says "OS: ANDROID 10.1" and build number is simply "ANDROID_TRUNK-p0" which I have never heard of.

there is only a video that shows how to create the backup but it is for phone, nothing mentioned on how to connect the head unit to the pc, and not reffering to power. do i need to use the test points from brick recovery guide in order to create the backup ?
Edit: i saw something about connecting the usb to the 4 pin port, but do i need to use some sort of male to male usb cable ?
Second Edit: my head unit has physical buttons, i saw that the guide is mostly for units without physicial button. Is it safe ?

If you have physical buttons on your unit (like Volume Control) then it's best to use this guide instead, as you currently have Android 8 API 27 installed, judging by your Kernel version.
The procedure of backing up a Mediatek phone and backing up your head unit is exactly the same. You do not need to use Test Point method if your unit is working.
All you need to do is to follow the guide in the link I gave you, step by step and you will be able to perform a full backup.
Hi. I have got the same. No Equalizer for Radio. There is Equalizer for mp3 player ( App is called Music ), but not for FM radio app.
In Music app, I can change tones like bass and treble, but not balance or fader. I can change balance only on Car settings, but there is no option to change fader ( front and rear speakers ).
Is there any way we can add even simple Equalizer to FM radio App? Or is there another FM radio app with built-in Equalizer?
My radio is Hizpo from Hizpo Europe Store, 2GB RAM, 16GB ROM, 8227L CPU, Android 11 ( may be fake ).
I am trying to ask Hizpo Europe Store about this, but for now I am getting default answers.

Hizpo is known for very bad quality units, intentionally scaling down the hardware to be able to sell the head unit cheaper.
If you are within warranty, return the product.
The reason for your issues is on the hardware side. You have no audio microchip on the motherboard.
Forgive me if this has been asked / answered before, but I did lots of searching and didn't find it, potentially due to my head unit being known under another name?
The Car and Setup:
* 2017 WRX STI with Harmon Kardon system
* Stock except for the head unit
* Bought the IDoing Head Unit 2015-2021 WRX / STI for Harmon Kardon (from WRXDaily)
* Followed Smeedia and Boost&Shutter video guides to swap out the old head unit and install the new one.
* Ran external mic up the A-pillar
* CAM-BUS decoder is installed
* HU shows as sprd ums512_1h10_natv
* CPU is UIS7862 Octa-Core 2.0 GHz, with 4GB Memory 64GB Storage
* MCU 2021.04.26 15:40:55 PSTAR_53_L6315_G23P48F64_V:1.0
* Android 10, Build number QP1A.190711.020
* I believe this is an FYT unit, more info here: https://forum.xda-developers.com/t/...unisoc-ums512-q-a-mods-tips-firmware.4396339/
Troubleshooting Attempted:
* Triple-checked that the cables were all plugged in correctly across the whole link and had no pinches
* Rebooted the head unit, re-connected the phone
* Ensured that all other functionality works (Android Auto Wired and Wireless, sound, backup camera, etc)
* Tested mic with a variety of apps, both with android auto and the head unit standalone.
* Tested with a variety of methods of activating the mic
* Looked for software option to enable it, didn't find it.
* All work resulted in the mic not appearing to pick up anything
* Went to Factory menu in settings (PW is 3368) and enabled the 'mic' option; no change
So what I'm wondering is if there is a software option needed to enable the mic, or I'm dealing with a hardware issue?
I suppose I could yank the mic out and plug it into another device, but before I do so, if anyone with some experience here could redirect me, what would be very helpful. Thank you in advance, and let me know what additional information you need.
Update: Added what I've learned about the head unit in case anyone else searches this post, and additional troubleshooting attempted.
Test the mic with PC or laptop first, Android may not register mic at all if mulfunctioned.
Thank you! I'll try this out; not looking forward to taking the dash apart again
Update: Haven't yet had a chance to test the mic with another device; poor weather + busy schedule + lack of desire to take dash apart have delayed. I do have a local expert who is checking if he has a 'known good' mic that I can also try

No need to take apart anything just connect switch / end odf a mic to a laptop while in a car (make a joint or if you have usb 4 pin cable ready)

Ok, I've torn up my dash again. thank you to everyone who gave me suggestions on the mic. Here are the results of my testing. Device details again for reference: iDoing FYT unit UIS7862 MCU 2021.04.26 15:40:55 PSTAR_53_L6315_G23P48F64_V:1.0
Validated External Mic by removing the 3.5mm jack and plugging it into the 3.5mm jack on both a microsoft surface tablet and an old Moto Z play
On the moto Z play, the phone was able to register voice via google assistance. The phone is on its last legs and died, so I switched to the surface
On the surface, I made a test call to a friend in discord, changed from the surface internal mic to the iDoing external mic during the call; friend could hear me and noticed the audio change. I also made 2 recordings, one with the iDoing external mic and one with the Surface internal mic. They sounded different but I could hear both
fully disconnected the harness from the back of the iDoing head unit and downloaded a voice recorder app directly to the head unit (phone was not paired)
Recording 1: Internal mic, "back MIC switch" in Factory menu set to "OFF - Front Mic"
Recording 2: internal mic, "back MIC switch in Factory menu set to "ON - back Mic"
firmly plugged in the harness in the correct spot (it was fully seated) and re-connected the external mic
Recording 3: external mic, "back MIC switch" in Factory menu set to "OFF - Front Mic"
Recording 4: external mic, "back MIC switch in Factory menu set to "ON - back Mic"
zero of the recordings picked up any sounds.
So my conclusions are that one, the external mic does work, and 2, either the iDoing head unit doesn't understand mic input, I have failed to enable it properly, or BOTH the harness and the internal mic are dead.
Any advice?
Last resort - use app called LESSER AUDIO SWITCH , download and install from Google Play store , there inside app you can set input and output for speakers and mic

Thank you! I will try that. This HU already has a method of boosting mic gain; did it to the max and no change.
The other idea I'm going to try is a USB mic, since I do have USB inputs

IDoing finally got back to me. They claim there is a bluetooth bug causing this issue, and gave me 2 files to "update" the driver. They sent me videos of someone plugging in UBS and the update just 'happening'. I doubt it's that simple. Has anyone performed this update, and if so, could they advise me on how to do so properly?

I think you must import those drivers from factory settings, there is import button.
Thanks! I tried this; successfully updated bluetooth, but no change in the mic. I am not surprised.
