Eonon Android 4.4.4 head unit - BUZZING MICROPHONE!

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

Please help! Klyde head unit in 2013 Hyundai sonata can't get the sound working

Hello
I've searched and tried plenty, and maybe this was covered but I can't find anything..
I recently bought a Klyde unit for my 2013 Hyundai sonata with dimension stereo and stock amplifier..
The wiring seemed simple enough, but I cannot get any sound through my speakers.
I did quite a bit of troubleshooting and even got a replacement canbus decoder from the seller but still nothing..
Is there a simple solution that someone else knows or should I just return the thing and get a different one..
Thanks a million I'm stumped
Edit: the rca cables have sound coming out but I'm trying to keep the stock amplifier and speakers..
The spdif signal going to the canbus "amp controller" box gets 12v power, I get about 200 to 250mv signal into it but 10mv going out to the car's harness
Is there a way to "enable" the amp controller like the Metra boxes?
Sent from my SM-N900W8

Anyone?
I have more pics if it helps
Thanks again

Bought a Metra amp interface and now it works

I am wondering if this might be how to solve my problem. This is the post I made on the large android head unit thread, do you think this metra amp interface would solve this for my lancer also?
if so which did you get and where, I think you have the same head unit I have.
"I just received my unit thursday I had it installed friday, but it was not giving any audio signal and the amp wasn't being turned on. They tried to manually turn on the amp, but there was still no audio coming through.
so I am wondering if there is anything I can do to troubleshoot it myself while waiting for a reply from the seller. There is a few notable things that might be the problem but I figured I would ask here to check before I start.
First there is a red wire that looks like it was cut right near the canbus unit it came this way out of the box, the installer said it had power to it, I am wondering if it's supposed to be cut or if reconnecting it could help, also there is a blue wire on the harness that is not connected into the harness also. will attach pictures. (or not because I am not allowed hopefully you can figure out how to see them below...)
red wire ------- pasteboard dot co/MO1wkXJ.jpg
blue wire ------- pasteboard dot co/MO6kqKs.jpg
back of unit ---- pasteboard dot co/MO9x1eI.jpg"

So what Metra Interface Kit...
I know this is an old thread but I have a 2014 Sonata Limited w/ Dimension Amp and android head unit doesn't output audio either with the Amp controller box or spdif box. I believe these boxes that came with it are not working properly. Please inform me of what kit I need to purchase.

Seeing reports...
I'm seeing reports the the hybl-04 is the Metra kit that you have ended up using. Is this correct?

"seicane" aliex - PX3 7.1.2 Bluetooth music A2DP quality poor

Hi guys..
Well first of all how I wish I'd checked these forums first before buying as I wouldn't have, second I wish I'd at least bought from the UK as I'd get some support. But hey ho I didn't and I'm stuck with it as returning to china seems to risky after the message suggested returning at a value of $70 so they don't get taxed and also making sure its sent by EMs so it doesn't get lost in transit like many units do at customs!!
So I bought what seemed to be an all singing all dancing unit from seicane store on ali express, for my seat ibiza mk5. According to the system info via root check app it's a px3, 7.1.2 android, rock chip, rk30sdk.
Amongst many other problems my main one is the Bluetooth audio quality over A2DP is horrendous, and it's not an amp problem as over aux or USB it's perfect. I've been looking at airplay using air bubble app and personal hotspot but it's too long to load and unstable I only drive 15 min to work so just want fast music to my ears! I've considered getting a Bluetooth transmitter and sticking it in the aux input but not ideal.
Anyone got suggestions as to what the issue may be and if it can be resolved?
Thanks in advance hope I can get this stable one day!

mine is also horrendous, and I also have a very short drive. Connecting a hotspot and launching app and getting a song, takes just too long for me. I'm basically already at my destination by the time I get it up. My workaround was to do what you said, and get a bluetooth transmitter and sticking to the aux, because aux sounds fine, but just bluetooth over a2dp sounds so bad, and has this distorted high end sound. This solution worked for me for awhile, but the only downside is you don't get song information on the head unit to display, which is a tad annoying for me.
I've contacted my radios reseller, and they're just ridiculously helpless, all they do is keep sending me a "software" update to fix it, but it does nothing. I've been searching for over a year for a solution, but have found nothing to fix it, other than what I just said. Problem was still there even when I used custom roms. SO I don't really think its a software issue, maybe some kind of hardware I can replace or modify, but I just really have no clue.

Yeh I've ruled out airplay as an option,
you've got me interested though as you're in a similar boat as me so hopefully can help, do you have the exact same unit for an ibiza or?
And yes thats exactly whats annoying me not getting track info, may as well just use the original head unit if i get a bluetooth transmitter!! which transmitter did you get? i've got a really cheap basic one years old and its got a high pitched whining noise in between song skips so its there just muffled out by songs playing, I'm wondering if thats probably just a cheap receiver I've got..
I'll try get somewhere with the hardware see about a new bluetooth module but no idea on the interface would be total guess work and risky at that, not even sure how to safely root this one.
Other issues i'm having which may be common and you may know? I got a dash cam which cam with a yellow RCA, an Acc+ wire, a ground wire and a 12V wire.. i don't understand why its got an Acc+ and a 12V, i thought similar things both transmit power just one off the ignition being on only? theres no 12v out wire on the head unit except 'cam pow' which I've tried to no avail. I plan on recording direct to the SD card on the camera.
Subwoofer out, does this work on our units? i bought it because i plan adding a 4 channel amp for F/R speaks and a sub amp for a single sub.. but does the rca not work / no amplifier control over it?!
Cheers hope to get somewhere with this as i feel a bit down that its not all singing all dancing like i expected lol.

i have a Seicane with Android 6.0 already, which I dont really have any problems with, but it is not PX3
however, I do have a Seicane with Android 7.1 on the way that does have a PX3. I'll report back when i get it to see if I have any issues

your bluetooth quality is as good as aux? i wonder if its a software bug..

Well the 6.0 version is totally different hardware

it is a known issue that no one seems to have a fix for. Im having this same issues with my PX5 Dasaita unit and had this issue on a previous Xtrons unit aswell. I believe it is a problem with the bluetooth drives not supporting the higher bitpools of recent bluetooth updates hence the bad quality. Ive even tried installing a USB bluetooth dongle but could not get the unit to recognize it.

Well I also have a Dasaita PX5 and I definitely didn't have a problem on that one. I would listen to Bluetooth audio on it pretty regularly.
Quick from Hot Audio did email me and ask about it, saying they had heard complaints, and sent me a new harness, but I haven't needed it

Well i've gone an ordered a car play dongle, so hopefully that will be a solution for good radio and a more functional nav at the same time.
Any tips for the dash cam guys? i ordered the 3 cable power one rather than a usb to keep the slots free.. not sure where i should hook them up to. (12V yellow, Acc+ red, black Grnd), i've only got an acc+ on the back of the harness and ground i made an earth wire to the car. Left the 12v off and it doesn't turn on. but my unit doesn't have a 12v, only acc+ or cam pow.

Got a pic or link to the camera you got?

So i have this camera..
https://www.aliexpress.com/item/140...32812106756.html?spm=a2g0s.9042311.0.0.MXwOS4
and this unit..
https://www.aliexpress.com/item/Aft...32827061575.html?spm=a2g0s.9042311.0.0.MXwOS4
The seller said to connect acc+ to acc+ on the unit, 12v to the cars 12v and grnd to the cars ground. I made an earth for the ground just to a screw towards the rear inside of the dash, but not sure where i'll safely take 12v from? especially with the car having a can bus if i splice any wires that may cause an error? Surely these units put out a 12v signal somewhere?
heres the wiring diagrams... https://ae01.alicdn.com/kf/HTB1z7DmnMn.PuJjSZFk763_lpXaZ.png
Also another Q regarding using an external amplifier for speakers and a sub.. is there an issue with the actual volume sent to the amps and can this be resolved? depending what input i give the head unit the volume differs, aux a lot quieter than usb stick or bluetooth.. but even both of them at volume 30 neither are really very loud where you here the speakers distorting, with a standard radio or branded head unit towards top end the speakers would distort so i can set a 'safe' max limit, my concern is the android head unit will limit the amp? and i've seen no info on rooting these units for viper4audio if that would help.
Thanks
Edit: how would i check if the 'cam-pow' wire is putting out 12v with a multimeter? just hold one probe to the wire and touch a ground point with the other?

BT & USB Support on PX5
Guys,
Sorry to tell you, the ROMS are very stripped down and as a result, the only support will be for the listing of BT modules that are on the main board and only for the ones list in the setup. You will not be able to add an external usb BT module to the head unit, it will not reconize them, and therefor will not work. Same with other USB devices. All support has been stripped out of the firmware. Some of these company's are getting slick enough to modify the firmware even more to only support devices that they sell, locking you into buying there junk. Good Luck! I had a BT problem with a Seicane Head Unit, and tried every possible, BT usb module only to find out what they do. Anyone want to purchase BT usb modules cheap!!!!!!

Dasaita Max 10

I hope I'm posting this in correct section. Has anyone got information on the newest Dasaita Max10-cp? I'm specifically curious about 1280x720 and Android 10
On AliExpress is says it's both 1024x600 and 1280x720 on same advertising page so it's very confusing.
Dasaita communication via messenger is very short answers and they don't seem to answer my questions maybe because there is a major language barrier.
It's supposed to have Android 10.0 among other things. If someone can provide some more info that would be great.

Apparently it's 1024*600 but 1280*720 is coming middle 9r the end of July. This is what I was told by Amazon Dasaita rep.

Hi,
I also bought this PX6 Max10 1280x720.
I found some issues after a few days of use:
1. When no music is playing I can ear a backgroud noise. The seller (Aliexpress MTKNAVI Store) is sending me a new RCA cable, still waiting for it...
2. I have a Toyota Rav4 2017 and with this Max10 all the lock doors settings doen't work such as:
- Lock all doors over 20kms/h
- Unlock when shifting P
- Driver lock button doesn't lock all doors
After speaking with Dasaita over FB Messenger they told that there is a new Canbus version and the seller MTKNAVI is sending me the new one.
So far, all the issues has been addressed by Dasaita and the Seller.
Try to reach Dasaita over Facebook Messenger.

He means the background noise.
They released a rca plugs to avoid that noise...normally coming from the stock amplifier....
Customer must specify the version of the car in order to check if the rca is required.

Get mine in a few days. Will post thoughts here.

Just got mine. RAV4 2014 AWD cruiser with amplifier. I have the same problem with the hissing and background noise does anyone have a picture of the RCA cables that are supposed to fix the issue - it's not these?

I have no idea what these rca cables are that people are talking about, but I doubt they remove hiss. I suspect these people are talking about ground loop noise which CAN be cancelled out with a special rca cable set.... but the hiss is coming directly from the unit itself.
I just ordered a dasaita max 10 and it's still in the mail but my old dasaita px5 is plagued with the same hiss issue which I was never able to get rid of. My guess is that my new max 10 will be the same. Fortunately I drive a jeep with a soft top and big mud tires.... which all pretty much drowns out the hiss
Are you connecting to your amp with the speaker level outs or the rca outs?

I don't think I'm connecting to the amp at all (JBL Greenedge)! I didn't end up using any of the cables numbered 3 to 11 in the attached pic and 14 - 17 are for the reverse camera and factory aux connector. There is no input for it in the bundle of cable harnesses that I can find...am I missing something here?
Thanks for the help, I've asked the seller on Ali about the harnesses - I'll share his replies here.

I Installed mine yesterday and have some issues I bought this one.

1. Once paired to your Note 9 go to bluetooth settings on your phone and choose the connection to the headunit. You can see a gear . Push it and check the profiles for the connection. Ensure "contact access" is enabled.
In case it doesn't work. Remove the paired connection from both headunit and phone and pair again. I remember the same issue and corrected after deleting and pairing again.
2. Gps offline. Which offline gps did you installed? If you mean igo gps...perhaps maps were not included...note that installed igo is just a pirated copy if the software...so no support
Isuggest you to get a good offline navigator (like "tomtom or "sygic"....or the free "here maps")
3. Check on factory settings that you have setuo the radio correctly to your region (europe, America1, america2, asia...) password for factory settings = 126

I have IGO nav on my Dasaita px5 and it is most definitely an off line system which does not require a connection. As @ikerg suggested maybe you didn't download the updated maps for your area? If you're talking about google or waze or some nav system like that... they are not really off line systems.
As noted on my above post, I haven't got my max 10 yet (still in the mail. It might come within the next 5 years or so given the speed and accuracy of China Post!) but I did notice with my px5 the request for permission to download bluetooth information (contacts, recents... etc) always came in like 10 or 15 minutes after initial pairing. Never did figure out why the delay, but give it a little while.
Interesting about the lack of hiss. I'm using the rca's directly off the back of my px5 (which I always assumed to be cleaner than the speaker outputs) to my amps and I DO get hiss. Even when volume is ZERO you can faintly hear it. Maybe I will try the speaker outputs

Sorry to be clear I am using the 2v rca outputs as well the y splitters are used for the adapter to the JBL factory amp and to my Kicker amp connected to the outputs from the HU . I guess Dasaita made this adaptor to send a better signal to the factory Amp to get rid of that noise Is my guesstimate Others have said it fixed their issues on the JBL system
And your right probably need to connect through hotspot again and go to maps and download the offline data just like my phone not used to a andriod HU as a stereo replacement.
Anyone know how to get the Max10 to auto pair with my hotspot I leave it on the phone side but have to keep hitting the wifi connection every time .The system setting is set to auto connect i believe.
OK FIXED the Max 10 Bluetooth issue after pairing go to phone icon on Dasaita hit the Sync button two arrows doing the spin third button down on the right menu . Then the request for sharing contact info showed up on the phone request and voila!

Sorry to be clear I am using the 2v rca outputs as well the y splitters are used for the adapter to the JBL factory amp and to my Kicker amp connected to the outputs from the HU . I guess Dasaita made this adaptor to send a better signal to the factory Amp to get rid of that noise Is my guesstimate Others have said it fixed their issues on the JBL system

Ah ok, so it arrived with your order? I guess I'll need to try and get them to ship the adapter out to me...
Does anyone have a pic of the adapter? I want to see if I could make it myself instead of waiting another month for it to arrive from China

Mine arrived in 5 days with DHL should not take that long. Honestly better to use the head unit power than the JBL but I was feeling lazy LOL

HeadUnit doesn’t support stereo sound

Hi friends,
The head unit I have right now does not support stereo sound, and when I play any music from my iPhone the sound comes from both left and right speakers at the time!
But when I play from the usb using the music app, the stereo sound coming from the right and left speakers with HD sound that means the Bluetooth apps don’t work correctly in my head unit.
Also, when I checked the developer option, I found that the setting sets in another option not as stereo sound, I tried to solve this issue from the developer settings, but when I change the voice type to stereo, the setting returns to the original.

Anyone can help me here

Did you already take in account that the issue is not on the head unit, but in your iPhone?

Really thank you for your attention.
No, for one reason I have another car, and the Bluetooth working smoothly in the factory head unit. supporting stereo sound and HD sound. Meantime I opened the development options and I saw that in the Bluetooth Audio Codec setting the sound is not stereo. I tried to change it to stereo but the system didn't allow me. also, no build number and I opened the Dev options using a shortcut app in the store. it is really Stuped Headunit.

FYI

Well... OEM unit may work different, because they are completely different.
It´s a known fact, that those iPhones have problems with most of the Android head units.
You should contact the seller and ask him for a solution. May be there is one.
...btw: This is a quite old unit with Android 8. May be you can update your unit.
Look for STM32 thread in here.
