Hi, not sure if anyone can help me, I have a unbranded android head unit and a couple days ago, the audio volume dropped on everything except the radio. I am lead to believe this is a software issue: not hard ware

and so I am absolute noob and need pointers of where to go from here. I have attached 2 images of what info I think is needed to find what updates I need. I do not see any MTCD/E from the ‘MCU’ and I don’t know what updates are compatible. Thanks for any assistance.View attachment 5152377 View attachment 5152381

Not MTCD, try searching for your MCU type (be creative) and post in appropriate [Android head units] forum.

Here's MTCE HXD MCU update version 3.56e provided by the supplier of my head unit for those that may need it.
[MTCD Android Head Units General] magnoman28:
Your HXD unit is PX6 (1280x720) ??????

If it is correct, could you provide me with dmcu.cfg ???

I would be eternally grateful!!!!!!
[MTCD Android Head Units General] csabex:
I also have PX6 with 64/6 and a newer MTCE CHS MCU version, the 3.65a_1 as you see in attached picture.

If you help me to save it and backup the original rom, then i will be able to give you anything you need :)

You can PM me, so we do not mess up the topic with unrelated posts.

hi . on my media i find mcu version AUD_7_1-NOV 18 2020-16:26:42_E_Q7_

ANY UPDATE FOR THIS UNIT? THANKS
[MTCD Android Head Units General] csabex:
I did it for you, but my version is 3.65_a1 and 1280x600. Maybe it's not good for you because of the resolution, but i leave it here if somebody needs it.

So this a PX6(1024x600) Android 10, with MTCE_CHS_V3.65a_1
[MTCD Android Head Units General] magnoman28:
Not good for mi because of the resolution.
[MTCD Android Head Units General] magnoman28:
Your unit's MCU is CHS, my unit is HXD. it's not compatible and you can leave your radio like a nice paperweight

[MTCD Android Head Units General] typos1:
IMPORTANT - You should NOT use an MCU with different letters to the original letters (ie a GS MCU on a unit that came with an LY MCU) unless you follow the instructions in the Cross Compatible MCU thread first.
[MTCD Android Head Units General] whitebait:
Thanks, updated my xtrons px5 unit with that gs v3.67 mcu. Everything still seems to work OK. I'd upgraded from android 9 to android 10 (hct4 ROM) just prior so I'm not 100% sure but I think it was the updated mcu that has led to "canbus version" now showing up on my system page (see attached).
[MTCD Android Head Units General] meduzo:
Hi, I have done the same update and everything is working but the CD. I'm able to eject/insert discs, but seems the head unit is not mounting it. I know that some head unit does not come with CD reader. Do you have same problem?
[MTCD Android Head Units General] marchnz:
Factory settings, CD?
[MTCD Android Head Units General] meduzo:
It is enabled in factory settings. If I disabled CD option, the eject button does not work, like no power for it.
[MTCD Android Head Units General] typos1:
Disable it in factory settings, reboot, then go into factory settings and enable it again, then reboot.
[MTCD Android Head Units General] meduzo:
same problem. If I set it to NO, Im not even able to eject/insert a disc, I can if it is Yes
[MTCD Android Head Units General] typos1:
So it wont play if its set to "on" ? If so check the ribbon connector inside the unit, if its ok, sounds like a faulty drive.
[MTCD Android Head Units General] meduzo:
It was a software problem, seems that the ROM installed didn't have the DVD app.

I have re-installed Android 6 from https://yadi.sk/d/umCvHqCDzHccr/RockChip PX5 Android 6.1/MX/update and every thing is working properly

Thanks all
[MTCD Android Head Units General] typos1:
ALL ROMs have the DVD app, no one has reported the DVD app not appearing (it would be a major bug !). I d say it was a minor glitch somewhere.
[MTCD Android Head Units General] Rezor:
Does the canbus list/selector depends on mcu version? I have 2 different units with same wiring and canbus adaptor but one is unable to get steering wheel keys working, doesn't show opened door status etc only amp is working
[MTCD Android Head Units General] typos1:
Yes - newer units have more car types, but not all car types show the info youre looking for, not all CAN Bus vehicles have CAN Bus SWC and not all cars need to have a CAN Bus type set in factory settings - some should be set to "none". What car is it ?
[MTCD Android Head Units General] Rezor:
Chrysler 300c with Boston acoustic sound system. I couldn't figure how to make steering wheel buttons work. With old unit everything was fine but it has no dsp and audio quality was poor. I bought new unit, audio is perfect but i couldn't control it, no fade and balance etc. Moreover i update mcu and now even when i choose wrong canbus audio still works. It seems that last choosed canbus was set permanent :)
[MTCD Android Head Units General] typos1:
Try setting CAN Bus to "none".

When changing settings in factory settings you have to click "apply" and it will ask you to reboot, click "ok".

You only connect the rear speakers if you have an external amp on the 300C.

You also need to turn down the db output in factory settings to 9 or 12db.
[MTCD Android Head Units General] Rezor:
Nothing changed, amp still works fine even with set to "no".

I know that it wants to reboot. This is another annoying thing with new radio. With previous one I could change canbus and all another settings without reboot.

Can you explain? Where an why I need to connect rear speakers? All speakers works fine. Also why I need to turn down output?
[MTCD Android Head Units General] typos1:
If you do not reboot then the new settings DO NOT take effect, this is the way ALL MTCB/C/D/E head units work.

The amp must only take power from those speaker inputs, my friend has a 300C with Boston Acoustics and that is how I set it up because that is the way the guide said to do it. He wasnt bothered about balance/fader controls so I didnt try and sort that. I dont think there is an output from the stereo to the rears in this set up, I think the CAN Bus distributes the sound, so if your fronts are connected its ok, but there is no signal on those wires. You need to reduce the db because without doing so you are using the head units amp and the cars amp and it sounds awful, plus it is far too loud - on the lowest setting the volume is much louder than it should be.
[MTCD Android Head Units General] Rezor:
I do reboot but like I said it is annoying. I don't know what MCU old radio have, it was labeled as 8227l and I don't need to reboot when I change settings there :)

However somehow I "blocked" can settings, after MCU update change have no effect.

First heard that I need to connect any speaker directly to radio. I have no issue with any speaker all plays sound. I don't need to reduce amp volume, moreover I think it is too quiet. On highest volume, sound is quite good and seems it can play louder. Maybe your friend set "loud" option in amp settings? It makes sound louder but also distorted
[MTCD Android Head Units General] typos1:
As I said ALL MTCB/C/D/E units need a reboot if you change factory settings, if you dont reboot most settings changes are not applied, take any complaints about that up with the developer of the MTC platform.

No, my friend does not have loudness on, your car/his car, like mine and many other OEM amp setups, uses the speaker outs to drive the amp instead of RCAs, so therefore sets the sound ouput to low cos otherwise its amplified twice, sounds awful and is ridiculously loud on the lowest volume setting. This is why these units have the facility to lower the output to the speaker wires.
[MTCD Android Head Units General] Rezor:
How about canbus list? It is possible to update it? Does anyone have mcu firmwares for HXD? I took newest from this topic but it doesn't help and blocked canbus settings
[MTCD Android Head Units General] typos1:
The CAN Bus list is updated with new MCU versions, a link to a list of new versions is in my signature.
[MTCD Android Head Units General] Rezor:
So it still missing BNR and XINPU canbuses option for 300C on previous unit everything works only when I set it to BNR or XINPU. Other like HiWorld, Raise and Simple have only amp functional like current unit,. What is CANBUS.UPDE in your repo?
[MTCD Android Head Units General] typos1:
Please stop mentioning your previous unit, it was not MTCD/E so it is not relevant here.

BNPR and XINPU are not CAN Bus manufacturers used on MTCD/E units.

It is not my repo and I do not know what the CAN Bus update is, you would have to search that on 4pda.ru.
[MTCD Android Head Units General] Rezor:
Just trying figure out what is wrong/different. Since both units behave same way with the same manufacturer is choosen I assume that adding support for missing ones should help. I thought that someone here have any idea how it is handled by unit. At least if you right I should focus at MCU not Android itself. Is there any source code or something available for MCU?
[MTCD Android Head Units General] typos1:
No source code for MCU. As I ve said AFAIK 300C should be set to "non" for CAN Bus on these units.
[MTCD Android Head Units General] Rezor:
With "none" set there is no audio, and error code in all ecus in car that communication is lost with radio. No connection with rear speakers is needed . Problem is with translate can frames. Mcu have "dictionary" that decodes amp frames for booting up and playing audio but all another are missing or are not valid. I will give a try mtcdialer, mtcutils or similar app. It already helps me to obtain and assign buttons in my prev 300c
[MTCD Android Head Units General] typos1:
The CAN Bus decoder that my friends 300C KGL unit came with was faulty, so I used a Connects2 decoder instead and it works fine set to "none" I cannot remember what the CAN Bus was set to with the decoder it came with, but some MTCD/E units with CAN Bus decoders should set to "none" anyway eg BMW E46s and Renault Megane 2.

does mcu is related with gps fix? I ve got a 5.1 mtcd unit. my antenna cables are ok, tried different roms and now on hal9k, my hu finds satellites, however it cannot get a fix for minutes and hours. snr is between 35-55 db. sometime it get fixed but lost after that. using cs-x 2.96 mcu
[MTCD Android Head Units General] typos1:
Not really but no harm in trying a more up to date MCU, dont forget to export your settings in factory settings before flashing.

Hello Professionals. I have a problem with MTCD_LM. After upgrading to any other version, the DVD drive does not work. PWRON DVD does not come out of pin 2 of the MCU. I can't find exactly my old version of MTCD_LM_V1.90. Could it be software or ARM to blame?

Without waiting for an answer, I checked myself. The convertibility of the MCU, however, is not 100%. I bought the radio damaged from the LM MCU. Everything worked except the DVD. I changed MCU to KLD. The DVD started working. The FM radio has stopped. Then GS. Now FM radio and DVD work. Bluetooh and wi fi also. I will test if something still does not work.

Hi guys, currently i have installed on my isudar head unit the MTCE 3.65_ LY (27 october 2020). I wondered if there was a new version of this specific MTCE as you know. I've read about a 3.69 version but now couldn't find any news. Thanks

Hi, if you take a good look, spydo.cd did not answer your question, but members Nealed. I do not recommend using updates MCU from other manufacturers, as irreversible errors may occur. I was looking for an update for your MCU, but MTCP_JP is nowhere to be found.

- The following settings can clear the navigation voice problem: Settings - Driver Settings - Navigation - Blend Mode.

Set the navigation program by default in the settings, otherwise it will swallow the end of phrases and mixing will not work.

- If you have a problem with the voice in the navigation, try using a different voice, preferably TTS.

- Try different navigation

- Last option to update firmware:

Un saluto a tutti; sei davvero un bel top team. Non so se è la pagina giusta, il moderatore può trasferirla nel modulo giusto se necessario, grazie. Ora vorrei parlarvi dei miei problemi.

Possiedo questa autoradio senza marchio. Mi è stato regalato, è per fiat doblò 2015. I comandi al volante non funzionano (ho provato anche altre codifiche fiat interne) ma al momento ho lasciato quella impostata e trovata di fabbrica (64), il vivavoce anche con l'aggiunta del microfono esterno è terribilmente molto rumorosa durante la riproduzione di file video in verticale. Puoi rintracciare il marchio e sono possibili gli ultimi aggiornamenti? Grazie spero nella vostra forza ragazzi.

I own this unbranded car stereo. It was given to me, it is for fiat doblò 2015. The steering wheel controls do not work (I also tried other internal fiat encodings) but at the moment I left the one set and found at the factory (64), the speakerphone also with the addition of the microphone exterior is terribly very noisy when playing video files vertically. Can you trace the brand and are the latest updates possible? Thanks I hope in your strength, guys
