Button illumination problem - MTCB Android Head Units Q&A

I have KGL v2.80. Button are always ON, even when ILlUM wire is disconnected. Factory Settings option for 'button lights' is unchecked (dusabled).
I found several posts about similar problem, but there us no conclusive explanation is this MCU version or ROM issue?
Can someone confirm / share experience with this issue?
Thank for help!

to solve that put mcu file modded from darkleo.

Thank you!
Yes it solves button illumination problem.
But...
It introduce horrible touch sound.... Instead of more or less acceptable beep, darkleo MCU uses some noisy piggy-inspired sound that is so strange that everyone driving with me in a car is asking is my stereo broken

Headphone and Speaker work simultaneously

Dear experts,
Sorry if this question was answered before, but I've been searching through the threads and couldn't find one..
I have a WM5 Orange Artemis (SPV M650) and I'm facing the following issue: when I play music with WMPlayer I get sound both through the phone speaker and the usb headphones. This is the same case with a friend of mine having the same device.
Probably there is some sort of a software solution to this problem, since with the already-installed FM radio application there is a button you can use to activate the speaker or to redirect sound through the headphones only.
Now I'm not able to use my phone as a music player due to this problem so any help will be much appreciated. Thank you!

Had this problem before, open up the volume slider part of the earphones with a small screwdriver (push on the plastic tabs that hold the 2 sides together) and separate the wires going into and out of it, I found some were crossing and moving them apart sorted it fine!
Hope this helps...
Thanks for yr reply Pjtheman, I will try this, though I will keep wondering if it were a matter of crossed wiring, why it works fine with the radio application!!
I'll open the headphones slider and see what I can find..
yours, Ksu
I've just opened the headphones slider and found that all the wires were duly isolated from each other..
Perhaps a solution to this problem is to install advanced volume controls that can mute and control the volume of the earphones and the speaker independantly. Does such application exist??
Thanks for yr help.

Guys,
Has anyone here experienced the same problem?? Am I the only one? Would you pls try and tell me if you have the same problem? Thanks for your help..

Bluetooth issue

I have a MTCC-KLD6-V2.97 Android 5.1.1 800*480, with a december stock rom.
Since I've installed it, I always had a problem with the bluetooth: at the first start, if I do a search does not find any device and from my smartphone I can not find the unit.
After a completely shutdown (with car off) and restart, the bluetooth seem to work properly and i can connect my phone; the same thing happens after I went to the factory settings or when it boot with Android logo instead of the configured startup logo (It appears to be a fresh start after a unit reset, or similar): I have to turn off the car and wait for the complete switch-off time, otherwise I cannot have a Bluetooth connection with my phone.
The problem does't seem to be related to the Rom or MCU, I made several attempts, and the problem still persists.
I don't know if it can be linked, but when I tried a Malaysk 5.1.1 rom, I had to disable the MCT Service module, because otherwise I couldn't always connect my phone.
Someone has encountered a similar problem? How did solve it?
Have you checked that you have the correct BT module enable in factory settings ?
I think yes.
Let me explain: when I received the unit, in the factory setting was set on IVT_BT type.
I always had this problem, so one of the attempts that I made was to change the type of form, and I have tried all the available ones:
WQ_BC5
WQ_BC6
Parrot_FC6000T
IVT_BT
SD_BC5
WQ_BC6B
WQ_BC8
SD_BC8
In all cases, after the boot, in the Bluetooth settings does not appear the name of the unit and the pairing code.
If I try to manually configure name and passcode, if I go out on the settings it lose them. If I try to do a search, no device found.
The only module that seems to work is IVT_BT, but occasionally causes me the problem I described above.
The unit has always had 5.1.1 rom, what I thought of trying to do is use a 4.4.4 rom (maybe the new Malaysk), it could be a solution?
AFAIK, apart from the Parrot modules that have just started to appear, MTCB and C units always come with BC6 BT module. KK shouldnt make any difference really.
The only way to tell from certain is to remove the top, does it have a DVD/CD drive ?
Yes, I'll try to disassemble the unit and open the DVD to check the physical BT module.
But I don't understand, if I configuring in the factory settings the BC6 module will don't see the unit name and passcode and I cannot set it up in the bluetooth configuration... Also the MCU version don't make a difference?

Thats why I said have a look at the BT module, to establish exactly what one it is.
You could try MCU MTCC KLD9 v2.98 and see if that works better, its newer.
This is the BT module; unfortunately I cannot see good the face with the processor, I should completely disassemble the radio and today I had no time...
However, it seems that there is nothing written over that show the kind of bluetooth ...
I think I'll have to disassemble everything, find someone that sell me just the module and change it

Its quite easy to remove the DVD drive and/or the side of the unit, there should be writing on the bit of the BT module that faces the side of the unit.
Bluetooth Issues
I have a question with the BT on my unit. I have the external Mic connected and people complain that they can't hear me and they always hang up me. Music works fine but on phone call I have to switch my phone to Speaker. Would disconnecting the external Mic would improve the call quality. Do you suggest I get another external microphone? If you do can you please link me to a good one. Please see the picture for my unit's information.

MTCE - Waze mutes all audio (radio, bluetooth music, etc... stop playing)

Hello,
I don't remember making any changes to this, but for some reason now anytime I open up Waze (my default Nav app on my MTCE), any audio playing becomes muted and stays muted. I used to have continuous audio when running Waze, except for if Waze had a direction or notification to give and then it would properly temporarily mute the audio. But now I get no music while having Waze on screen. If I go back to the radio app let's say, audio continues as usual.
If I run any other app (say Google Maps), I still get audio as per usual.
Anyone have any ideas?
Thanks
Here also same pb. MTCD px3 android 5.1 with Hal9k rom on HU. I can't find any setting for sound on app or in OS.
Yo ozzyboy,
Did this problem occur for you recently? It happened to me within the past week or so. Again, I don't think I have made any settings changes in that time period.

I think I found the fix in case anyone else is wondering.
Go to Settings>Car>Navigation and look for something along the lines of Navigation sound mode. There is a toggle for me that turns some kind of navigation sound monitoring on, and then that enables several options below. One of the options is like "switch" or something to that extent, and then you can play around with how much the radio lowers it's volume while the navigation is talking. I guess mine was somehow totally disabled and that's how I lost sound, but I have it back now.
Hope this helps.

No Sound just beeping from buttons and touch screen!

Hello, my friend buy from Aliexpress android HU with android 9.0 4ram/64 rom,PX5. So, the problem is, when he connect the HU outside the car panels, everything is working fine. After this he install the HU in the panels and connect the subwoofer with Hi to Low level converter, like the original Peugeot 407 HU. Next he turn on the HU and.... no sound, just the button beeping. He send the HU to service and after 1 month they return the HU with the same problem. So he send it to me, i'm not a expert and is my first time with android HU. I connect the 2 plus and 1 minus cables to the laboratory power supplies and i start to measure... When i play some song from the HU i can see with the oscilloscope the song from the MCU is going to the DSP. After the dsp i lost the signal. When i measure the TDA7851 i can see the beeping on the oscilloscope so i thing the is no problem with the TDA. If somebody can help to solved this problem? I'm not sure but i will order the dsp chip Adau1401a and the audio switch: sgm6510 or sgm6502a i forgot which one is the switch.Sorry for my bad English
The button beeps? but doesnt respond right? Does the touch screen on the screen works and you're able to navigate menus?
Not an MTCB, wrong section.

Everything is working, buttons, touch screen , but the only sound is when you touch the screen or push some button. No radio sound, no BT sound, no CD sound...just beeping when you use buttons or touch screen .

Can you show me please , where to move the question?
That HU could possibly be an MTCD/E. Check the MCU string in About under the Android settings menu. If it's not MTCD then you could try the Android Head Unit forum.
Look through the HU setup menu (the gear icon) for a setting that relates to using the factory amp.

Dear momchil 7702
I have the same problem, everything works on my headunit (Dicola XRC7112NP), but sound is only heard when the headunit is turned on.
I just took it to a mechanic, replaced the MCU chip (BD37033), but it didn't work. Then I asked the seller for an MCU update, instead of sending an Android update, it was installed, but nothing changed. MCU firmware not sent in vain please.
I'm here, I'm clueless. And what about you, did you manage to achieve something?

Dear Momchil! Thanks for the reply, I am trying to replace the DSP processor, the only problem is that the processor cannot be identified, there is no caption on it. I asked the seller for help, but I haven't received it yet.
I wish you good luck with the repair!

Hello,
i forget to write a comment... When i change and the audio switch, again the same problem... So i assemble the navigation and send it to my friend. in this 4 month i bought second hand navigation and sent together . He receive the navi's and try the second hand and with the problem . And 2 navigations is working fine. So i thing the problem is on audio switch or with the dsp ,but you need the car to test, because is working with CAN interface ot VAN i'm not sure.
Thank you.

Problem with the can bus Citroen C4 assembly of a dedicated Chinese Headunit.

Hi
I have a problem with the can bus
ciytroen c4 assembly of a dedicated chinese.
The problem appears after plugging the radio into the cube after the serial one, namely the canbus module beeps pulsating. I will add that the radio turns on, receiving stations, they can be operated.
I will add that after configuring the module in the radio settings, the steering wheel buttons work this way. means there is communication and it still squeaks. I tried to insert the bundle with the module also squeaks.
watch it

Hi
If you didn't manage to solve the problem yet...
You need to setup the can bus decoder in your head unit and then the beeping will stop.
If you need help just ask!

Hi,
I'm dealing with the same problems.
Some of the car functions you can change over the car settings app.
And there should be a car info app which shows fuel consumption.
I'm still using the OEM multiscreen with steering wheel to change car settings.
But when using that I have the issue that all OEM displays get off and on during driving.
I'm trying to find a solution.

True, but I think the problem is related to the canbus module. So wanted to check if someone with similar problems did find a fix
Hi to all. I finally got a newer Andeoid version for my headunit and now all informations I need or I expected are showing on my headunit.
Everything before the update wasn't shown now appears like doors open informations, ECU fault codes, fuel informations and consumption, AC informations everything is shown like a popup information. And all that withe the Rais canbus decoder. The small original display I kept cause of the missing informations on the headunit is now not needed any more.
If someone still have problems with the canbus all you need is to update your andeoid unit to the actual version for your unit.
Can you advise what your canbuse settings are ?
Inside of the factory menu ?
I just installed a android T10 unit with a Raise canbus module. But only thing that is working on my Citroen C4 are the volume buttons...and even that does not work correct. I i press the menu button on my steering wheel sound also go up

Have you gone to Car Settings under factory and selected the relevant file under Can Setting? R011 is for Citroen C4 where the steering keys work fine, however my instrument panel keeps flicking between kmph and mph..
R016 works fine but only volume buttons work and the display screen thinks CD or radio is on.. (see picture)

In my android radio version, I didn’t see anything like “R0..” When I choose version of canbus “raise” -> psa/Citroen -> I have only models of car and I get C4L. Everything works like steering wheel buttons but I have problems with resetting displays and appearing diagnosis.
