KLD microphone never worked - MTCD Android Head Units Q&A

Hi guys, I have a problem with my unit eonon Ga8161 7.1 px3, KLD. The microphone does not work, it never did (external, I think there is not), I tried with Bluetooth and with Google now is not signs of life .. Cables are ok. The company sent me a new Bluetooth module, I soldered but nothing, the problem remains, even a friend of mine with px3 mb KLD has a similar problem and the company is going around and wants the radio back to China .. With timing very long .. Can you help me figure out where to check? The MB seems to have no welding problems.
Please help me. Thanks

I replaced again with a new MB, for about 3 days it worked perfectly, now it does not work anymore .. Help please

seicane unit?

Not many manufacturers make head units to match my car, a 2004 C5, even less with the newer PX5 units. I did find this one,
https://www.seicane.com/android-199...mirror-link-backup-camera-dvr-obd2-dab-s32577
Anyone familiar with this brand? Do they make their own or repackage?
What 2004 C5 is? (I expected a Citroën C5)
the link you provided is for a 2004 Audi Series (A4, A3, A6)
I think the same Audi you linked is on Daasaita (HotAudio):

Audi C5 is the Volkswagon/Audi platform code,
https://en.wikipedia.org/wiki/Audi_A6#C5_.28Typ_4B.2C_1997.E2.80.932004.29
What I need is for the A6 only, not the A3 or the A4. The A3 and A4 both use a different size face plate. I need one for the A6 from those years specifically.
anyone have one of these Seicane units?
is there any reason to think it's any different than the other PX5 units as far as modding and firmware upgrades?
thanks!
Hello, yes I do have a unit bought by Seicane SELLER.
Seicane is just reseller and you will get all sorts of units built buy other MANUFACTURERS if you buy from them.
In my case I bought a unit for Subaru and found it to be an MTCD device built by Klyde (MCU manufacturer code: KLD).
So as of my current knowledge you won't really know what manufacturer built your unit until you check the system about screen for the real manufacturer. And as a result the devices are no different than the ones bought by any other reseller.
Don't buy from them, they have worse to NO service at all!
I have a broken (warranty) seicane unit, i am mailing with them now for 1,5 month to get instruction how to send back.
They give bull**** answers or ask bull**** questions to keep you waiting, after a while they stop responding.....
I advise do absolutely NOT BUY from them, just a worse and also expensive seller....

I know they are sellers and not manufactors, but have no idea who is the manufacturer.
But warranty is given by a seller, not a manufactor, they sell it as there own but give no support what so ever on it.
If you have a problem they simply ignore it and hope you stop complaining and so there problem is gone.
Please make sure if you buy from China that you chose a seller which does give support!
The problem with my unit is it does not turn of anymore.
When plugged in it directly boot up, also when acc is off, when acc is turned on and off agin it should turn off by ACC control through can-bus control.
It seems can-bus is not working properly anymore....
When i asked support i get the most stupid answers such as:
check the 12V acc wire is connected... DUH there is no 12V acc wire in my car, it is fully can-bus, also there is NO 12v acc wire in the connector of the radio!
This then i get 4 times to check!
Now i get 5 weeks (i contact them 3 times a week) that there engineers are checking the software, FIVE WEEKS !!!!!
I am now aprox 9 weeks contacting them how to solve this (the unit was when i first reported it under warranty, now it is out of warranty...)
I never buy/order from them again!
I hope no one does!

I know a lot of sellers have bad support. I m just trying to see if I can help.
The stereo will have pins for ACC even if the loom does not have wires, what ahv eyout ried so far ? Have you asked on here for help ?
The MCU type will tell you who makes your unit.

Yes thx for any help, but the problem is within the canbus decoder i believe.
It is a unit specific for a Mini cooper, it has besides the radio/android part also the dials for fuel, obd and other car control lights etc, these also do not work properly anymore.
This car section is also controlled by the can-bus part of the unit.
The android part itself works fine, it is the can-bus part which is not working properly anymore.
The MCU have the letter KGL in it, i have really no idea who is the 'real' manufactor, but i actually doubt the manufactor will help.

Yes, I know the type, it has a round screen. KGL are the manufacturer - Shenzhen Kai Ge Le.
In factory settings, how many options are there for your car, for Minis ?
You can list CAN Bus decoder by manufacturer, how many many are showing for Mini ?
I ask this because you may be able to sort things out by getting a new CAN Bus decoder.

Seicane = Bad Customer Service + Do nothing for you after the sale.
I purchased a Head Unit from them back in June 2018. The bluetooth module has never worked and after going around with them about it, they sent me a different module, not the Parrot BT module I purchased originally. Replacement of the BT module requires disasembly of the unit, de-solder old BT, solder new one, but the reason the BT did not work was that a few of the SMD resistors were damaged during build or soldering the BT module in. 3 months since purchase and still dont have a working unit. Now they want me to ship the unit back but I know they will void warrentee due to customer opening the unit (not the factory), and will claim I damaged the board attempting replacement. Oh, did I tell you they never told me the BT module was soldered onto the main board?? When they offered to ship a replacement BT I was under the impression it was a snap in module simular to how PC processors or flat cable connectors lock in. They knew, but dont want to deal with problems.
Remeber, they are only resellers, not the manufacturer. They all buy from the same manufacter for the most part. Good luck if you do get one that works as expected from them.

Hi typos1,
The spec for my unit as follows:-
Head Unit: Seicane s081988f
OS: Android 7.1.2 (Nougat)
CPU: Allwinner T8, 8-core Cortex-A7 @ 1.8GHz
Memory: 2GB DDR3 RAM, 16GB EMMC, 2xUSB2
Display: 9", 1024x600 capacitive
MCU Version: T8.3.19-23-10-E43101-171127
System Vers: V9.2.2_20171202.103838_TW2
Linux Kernel: 3.10.65 (20171129)
Security Patch Level: 2017-07-05, 7.1.2 (Nougat)
Issues still unresolved:
Microphone only works for phone calls, no android apps (no OK google)
Screen calibration slightly off by 0.5cm
Audio from AM / FM radio good, but Android apps (google maps, Spotify, youtube etc) audio louder from front left channel than all other channels
no root, unable to add some apps that I would like
Using AM / FM radio and waze, an alert in waze mutes AM / FM radio and it does not return. This doesn't happen in google Maps
When using google maps, something happens to the audio where it sounds like it changes the audio fade to front speakers more than rear speakers but when this happens the balance between left and right seems to be corrected resolving issue 3. System audio preferences for navigation set to use all 4 speakers but doesnt appear to be working
I suspect that there are other issues that I cant recall right now but whats listed above is enough to be unsatisfied with the product. The primary issues that I need resolved are the Microphone and the Audio being all over the place depending on what app is used. It just needs to be consistently balanced left to right, front to back right in the middle for all apps.
I am not against using an updated system ROM or MCU but I am not knowledgeable in this area and despite doing quite a bit of research I still havent figured out if there is a compatible release that I can apply to my unit, and frankly with all the time invested in research, forums, testing and trying to resolve issues with the re-seller I've got more important things to do with my time (work, family, hobbies)
Any assistance that can be provided would be greatly appreciated and rewarded.
cheers

I bought about 9 months ago, directly from Seicane a radio of 9 "android 8 PX5, 8 core 64 bit cortex A53, memory 3891 MB, MCU MTCE HF V2.86 May 28 2018, for a Subaru Forester, the integration and the connectors are excellent but the radio had problems with the bluetooth handled by google and when connecting the cell phone via usb Easyconected, it did not recognize the cell phone, I asked for support but the solution from them was simple, and it was still the same, at the end I found a firmware of Hal9k, I installed to the radio and with this all these problems were solved, the link is "https: //forum.xda -developers.com/android-auto/mtcd-software-development/rom-hal9k-rom-3-mtcd-e-head-units-t3847477 ", Seicane never respond very bad seller.

You have an Allwinner chipset (not Rockchip or Intel Sofia) and "MTCD" or "MTCE" does not appear in your MCU field, so you dont have an MTCD/E unit and are in the wrong forum, try the Android Headunits general forum.

PX5 Octa Core Android 8.0 XRC No Sound

Hi,
i`ve got a problem with my
PX5 Octa Core
it`s using MTCE_XRC_V2.93_2
suddenly the sound disappeared.
Everything working nice for about 2 weeks and then it happens.
I checked wiring, trying to back to factory defaults, and nothing.
Strange is that the "clicks" when you touch the screen, or when you setting volume with knob are audible.
I`m looking for solution for about a month and find nothing.
Maybe someone has the same problem, or know what to do?
Thanks in advance
What did the reseller suggest when you contacted them for support?
to update MCU, to that one i wrote before.
no change.
They suggest to send it to them, but for now i`m abroad, and the shipping costs are horribly big

PX6 mic and DSP questions

Old 4.4.4 head unit died yesterday. I went to best buy to look around and was woefully underwhelmed.
Time to get another android HU.
When looking at PX6 RK3399 head units does it matter if it has DSP or not? Does this really make a difference? Do custom ROMS (Malaysk) support it?
I never quite got the microphones on the old one to work well with bluetooth. Always a lot of noise. Is this still a problem with the newer PX6 units?
Thanks in advance!

Do you have a hammer. Return under warranty or replace SOM might be the best option.
You're looking for someone reading these forums to guess what the issue is with your unit. It is unlikely a software issue and apparently unable to work at a hardware level.
Had the same issue with mine a PX30 unit with MTCE MCU version.
Turned out that the Canbus is rejecting the unit.
I have a Opel Corsa D. Astra H have the same issue.
If you have steering wheel integration, you have to connect the CanBus Decoder to a seperate 12v connecting like cigarette lighter.
Preferably also the power to the unit itself (not when Canbus Decoder is feeding it).
Both CanBus Decoder and Head unit must be not be powered when carkey is removed.

In call speaker (earpiece) stopped working, replacing the module didn't fix it

Hello everyone,
The phone is a leeco x526 bought from banggood couple of years ago
Suddenly the in call speaker stopped working
I went on and bought a couple of earpiece module replacement from aliexpress,
I've disassembled the phone and replaced it, but did not solve the problem: still no sound from the in call speaker.... tried both the earpieces I bought
All the rest is working fine, including the loudspeker on the bottom.
PS. I've also tried reflashing the rom (even the stock one)
I don't know what to try next, hoping some guru around here can help me
I'm almost tempted to try the oven trick, but I'll wait a few days to see if anyone can gives me some other idea

Can you upload photos?
Perhaps the connection of the replacement speaker is weak?
Or maybe the contacts on the main board a little loose
Pictures would be helpful
Thanks for the answers.
I'm not sure if it's Hardware or Software, but I think it's hardware since when it stopped working it didn't had any update/rom flash/etc
I've tried to clean the contacts on the pcb
The earpice is not misplaced cause it's forced in the right position by the black plastic cover that sits over the pcb
Here's a pic, sorry for the weird quality:
I've tested the 2 earpieces that came from aliexpress with a multimeter in "continuity mode" and for both the value is around 30, I think they are ok.
I don't know if there's a way to test with the multimeter those 2 points on the pcb where the earpiece should sit.
Well I guess I'll give the oven trick it's chance next weekend, then I'll toss it away or use it as a car gps
