---------- Post added at 08:32 PM ---------- Previous post was at 08:30 PM ----------

Sorry Just a little confused I guess? I just got XTRONS PF85MTVA to replace my PF83MTVA it went haywire. What are the benefits of updating the MCU? Is there a changelog somewhere?
[MTCD Android Head Units General] masri1987:
no changelogs.

Hello.

I have the 1.71_1. I did not find it newer and that works. If someone has, I am also a taker.

Witson does not reply to my posts about updates.

MTCD_HZC updated MCU

I've got the updated MCU from Shenzhen Hansong Electronics Co.,Ltd which is the supplier of the MTCD_HZC units.

w w w . mediafire.com/file/ou3t46c1khb3fy2/MTCD_HZC_V2.58.rar

Thanks Bose321
[MTCD Android Head Units General] Bose321:
Just remove the http part in front of the URL.
[MTCD Android Head Units General] typos1:
Theyre not the "supplier" theyre the manufacturer, we didnt know what HZC stood for before , now we do, so thanks.
[MTCD Android Head Units General] dguski84:
Is this MCU also for the Xtrons TB103AP ?

I´m current on "MTCD_GS_V2.43_1"
[MTCD Android Head Units General] Alexdepalma:
I'm not an specialist but as far as I know all GS units used the same MCU. So I think yes.
[MTCD Android Head Units General] typos1:
You don't have an Xtrons unit, Xtrons are a seller they stick their badge on other people's products and sell them on, you have a GS unit and as [MENTION=487370]Alexdepalma[/MENTION] says if you have a GS unit you can use any GS mcu

i just got MTCD_XRC 2.54e, seems very new, latest i saw on 4pda was 2.54a

will test today
[MTCD Android Head Units General] ikerg:
Normally....that subversions don't exist.

They are the same mcu version but specific preconfigured option (I.e. customer version)

Enviado desde mi D6603 mediante Tapatalk
[MTCD Android Head Units General] typos1:
All the customer versions I ve seen have been numbers, not letters.
[MTCD Android Head Units General] zerozoneice:
it is 2.54e indeed.

i notice now that my "source" button on the steering wheel cycles thru radio/music/poweramp, whereas before it didn't do anything.

also pressing "previous track" button on the steering wheel now restarts the song and if you press twice, it goes to the previous song. It mirrors the setting in poweramp exactly. So far is definitely an improvement.

I also checked "Audio" menu in Maxidot, but no changes there: for radio it shows the MHz value of the preset and for music it shows Track# and MM:SS.

For Poweramp it just shows "Video" as source with no Track# or MM:SS.

As far as the OS goes, i didn't update to the version they sent me because it's older (7.1.1 from 20170705) than what i have now (7.1.2 from 20170721)
[MTCD Android Head Units General] typos1:

[MTCD Android Head Units General] zerozoneice:

[MTCD Android Head Units General] typos1:
Ok, thanks, mine isnt in the car but they will not come on all the time (which I prefer) even when set to.
[MTCD Android Head Units General] zerozoneice:
I think there's a setting in factory settings which controls that.

but the lights should come on, that's the whole point of having buttons of any kind (capacitative or physical) :)

besides, the lights help when timing to enter recovery ;)
[MTCD Android Head Units General] typos1:
Lol, yes I know all about the lights, I know they flash to get into recovery, I know theres a setting for it, as I said in my last post, they DONT work when theyre set to be on all the time !! (In fact come to think of it they dont work at all on both the units I have with capacitive buttons).

Think you need to re-read my last post !! :)

My MCU version is MTCD_KLD_V2.00c_1 (built on December 5th of 2016). Any place I could find upgrades for those?

---------- Post added at 10:46 AM ---------- Previous post was at 10:42 AM ----------

Could you point me in the direction of this MTCD MCU thread? This is pertaining to MTCD_KLD_V2.00c_1. My chip is RK3188, not PX3 or 5.
[MTCD Android Head Units General] typos1:
PX3 and RK3188 are one and the same thing.

An MTCD MCU is an MTCD MCU regardless of processor (like MTCB units).

If you have a KLD MCU you can use any MTCD KLD MCU.

This is the MCU thread, also check the threads with "PX5" in the title theres a lot of later MCU in those.
[MTCD Android Head Units General] Atlanntas:
I'm confused by the terminology a bit still. Aren't PX3 and RK3188 separate chips though: http ://www.rock-chips .com/a/cn/product/index.html ? Is the MCU always not dependent on the CPU make (a lot of MCU threads have specific CPU models in their titles, so it's kind of weird if the MCUs perform entirely irrespective of the CPU)? I am inclined to trust you, just trying to really understand the ground I'm treading.
[MTCD Android Head Units General] typos1:
No, the "PX3" is a renamed RK3188, they are identical.

Yes, loads of MCU threads do have specific CPU models in their titles, your ll also find loads of threads entitled "Erisin ABCDE1234" or "Pumpkin 987XYZ" and such like, even though Erisin, Pumpkin and others are sellers not manufacturers, this is because a lot of the OPs havent read the wiki or other threads before posting and dont know what theyre talking about.

None of this changes the facts that, as I said, the MCU is entirely separate from the processor and what seller stuck their badge on a unit they bought from a manufacturer and sold it as "theirs" is not relevant, only the manufacturer (found in the MCU field) is.
[MTCD Android Head Units General] Atlanntas:
Wow, thanks. You're really helping me navigate this thing.

But the MCU firmwares are related to the Android version/firmware somehow, yes? Or is that just another thing people put in the name of their zip files for some reason?
[MTCD Android Head Units General] typos1:
No the MCUs are not related to Android, the reason why it can appear in the update is that the ROM part of the update IS specific to the processor and sometimes the MCU is also bundled with it.
[MTCD Android Head Units General] ekduyan:
Unknown version?

Mine says WLGK i can't find it on the list.

[MTCD Android Head Units General] dirty_dty:
I have 2.54a_1.. Any way to update? And what benefits would it bring? Also if I update it do I also need to update the Android version? I have 7.1.2
[MTCD Android Head Units General] typos1:
Read the first post, read the thread ! !

Stick it on an sd card and it will auto update, the MCU has nothing to do with the Android version or indeed your processor version. There are no changelogs for MCUs but its usually best to have the latest.
[MTCD Android Head Units General] dirty_dty:
I understand how it is done but on the first post in here I do not see XRC links.. can you be more specific on where I can get the XRC version? Thanks.
[MTCD Android Head Units General] typos1:
If there are no XRC MCUs in this thread and on the 2 fileservers in my signature, then look in the RK33678/PX5 threads, (there are about 4) people have posted some in them, if you cant find any there then google "xda MTCD XRC MCU", that may pull up some threads with XRC MCUs in..

If you still cant find anyl, then your ll have to try and change your MCU type (if you want a more up to date MCU), for this look in the "Verfied Cross Compatible MCU" thread.
[MTCD Android Head Units General] S@lman1996:
Latest Android, you can search in xda, I even got it from another xda thread.

I've attached the MCU update.
[MTCD Android Head Units General] typos1:
Can you add what version the MCU is to your post so we know ?

[MTCD Android Head Units General] Flockrock:
I changed the PX3 board with the new PX5 board yesterday.

Are there two seperate MCUs for PX3 and PX5 boards or can I still use the same files?

What is the latest version of GS?
[MTCD Android Head Units General] typos1:
MCUs are the same regardless of processor, annoyingly a lot of the latest MCUs are in one of the 4 RK3368/PX5 threads rather than in this one.
[MTCD Android Head Units General] S@lman1996:
If you don't know something, please keep quiet rather than saying some useless things. I'm already a member of xda and I've posted many things and helped many. Please note, We are a part of XRC development group.
[MTCD Android Head Units General] typos1:
Yes, ok but please add the version number to your post so people can see.

What the hell is the "XRC development group" ??
[MTCD Android Head Units General] S@lman1996:
See, read those threads carefully and answer. Actually I uploaded it,since "dirty_dty" asked me. I forgot to mention the version in the post and I replied it in the next post.

I want to know why you used the word "hell"? I hope this is not a social media to humiliate others.
[MTCD Android Head Units General] typos1:
Fair enough, I checked your original post before I wrote that, I didnt go through all your subsequent threads.

Different MTCD manufacturers

Hi. I am new in this forum. I recently bought a MTCD_ZYC head unit with Android 7.1.2.

For the moment is working well and I'am reading as much as I can about MCU's and version.

I noticed that the ZYC is not very popular, but I've seen the Malaysk ROM for MTCD, but I am wondering if I can use that ROM for my MTCD unit, or it must be specific for my brand.

Thanks in advance,

Francisco.
[MTCD Android Head Units General] typos1:
The manufacturer is not relevant for the ROM, only for the MCU software. Its not so much that ZYC is "not popular" its more like "rarer" - no one buys based on MCU/manufacturer version, indeed they wont even know what the manufacturer is until the unit arrives.

There will be a problem using Malaysk's ROM for the RK3188/PX3 2 Gb Nougat version though - there are some slight, mods that mean it wont run, they could easily be overcome . . . if youre a developer.

[MTCD Android Head Units General] arshish1612:
Hi,

I have the new PX3 with version MTCD_MX_V2.56b_1 with 2GB RAM running Nougat preinstalled bought from JASCO Store on ALIEXPRESS

I am facing a few issues:

1. Bluethooth CALL audio is not audible. Streaming music works fine. If i change the FADER to REAR then I can hear the person but as soon as I touch the volume knob the audio stops again. I have only connected the rear speakers as of now. Could it be that by default, Phone call audio is only sent to front speakers?

2. Any app with a white / light backdround looks TOO light. Example Google maps, looks almost completely white. I've used an APP called whitebalance to improve things a bit but still not that good.

3. Despite being the New PX3 version with Nougat and 2 GB I still feel its slugish. Can I buy an upgrade board to the octacore based PX5 and will it make a difference?

4. Are there better higher resolution screens available that can be custom fitted to the head unit? The screen has a very low 240DPI.

Arshish
[MTCD Android Head Units General] typos1:
You could buy an octacore SoM and put it in, but personally I think both the 2Gb N RK3188/PX3 and the RK3368/PX5 seem about the same speed - I cant tell much difference between them.

The only screens available are 800x480 and 1024x600, both have 240dpi, you can change the dpi with an app.
[MTCD Android Head Units General] arshish1612:
Thanks for replying.

1. How could I get the screen looking sharper?

2. What are "SAFE" DPI's I can change to without the screen going blank

3. Can the resolution be changed? Mine is 800x480
[MTCD Android Head Units General] typos1:
No you cant change the resolution, you could change the screen, if youve only just got the unit and the seller sells a 1024x600 version you could send it back and buy that.
[MTCD Android Head Units General] AndHead:
For point 3 you can try Easy DPI Changer. (Requires root and of course will not change what the display is capable of doing. But worked for me the best to get Spotify displayed correctly in my 800x480 display)

I'm running the MTCD_MX_V2.56b_1 with N. Is root available? Can someone point me to the thread with instructions.

BTW, I spoke to the vendor. His page advertises 1024x600 but the product he has is 800x480. When I questioned him he said that for there is no 1024x600 version because of the small screen size. Has any one tried fitting a custom screen with better DPI and resolution?

Hi Guys,

I'm stuck!

I just changed my wiring to use the low level RCA outputs to my amp rather than the high level speaker outputs. I got no audio.

I checked each RCA at full volume and I'm just getting 0.0Volts on a multimeter. Which means there is no output to RCA.

Any ideas what could be wrong?
[MTCD Android Head Units General] typos1:
Strange, have you disconnected the speaker wires ?
[MTCD Android Head Units General] arshish1612:
Tried with speaker wired connected and disconnected.

Checked with a voltmeter. Getting 0 volts.
[MTCD Android Head Units General] arshish1612:
Any Ideas? I tried maxing the system and radio gain in factory settings. Made no difference.
[MTCD Android Head Units General] typos1:
I ve not heard of this before. It seems that theyre not connected, opening the unit up would be the next thing I d do.
[MTCD Android Head Units General] arshish1612:
Nope.. All connected inside. See attached.

I guess I'll just have to run it on the high level speaker wires.. So disappointing. Sending it back to China from India is not worth it..
[MTCD Android Head Units General] typos1:
You can get high to low level converters but its not an ideal solution.
[MTCD Android Head Units General] echudoba:
Aren't you measuring audio which is AC, have you tried ac on your meter? Edit: Haven't found the specs yet but 200vac may not measure it. I always though rca's were low level 1-2 volt peak to peak. Could try to listen to one with a headphone / earpiece.
[MTCD Android Head Units General] arshish1612:
RCA voltage is AC? Oh... I did not know that.

I've actually wired it all up and installed everything with the high level outputs now. I have a digital sound processor in any case so should not be too bad.

I'm sure there was no voltage on the leads because my sound processor uses signal sensing to switch on. It can detect a signal as low as 1volt on the RCA / high level input. When I wired it as RCA it just would not switch on. Works fine with the high level leads connected.

Took me 2 hours to wire up and pull the RCA leads from the HU to the back of the car and another 2 hours to take them out and run high level wires all the way back to the boot!
[MTCD Android Head Units General] bgroper:
Seems a small PITA.
[MTCD Android Head Units General] marchnz:
Have you considered creating new preamp outs by tapping into the audio imputs to the internal power amp via a decoupling capacitor? Alternatively you could try tracing the existing preamp leads (use the schematic as a guide in my signature) to try and figure out whats happening. If they're connected ok, the first place I would check is the muting circuit.

Happy to answer futher questions in a new thread to avoid hijacking this thread, this thread is for posting new MCUs.
