typos1,​

yes , sure i will make a backup,

i read the most of the thread,

and i think to flash HA mcu,

since they update the MCU frequently,

and i also see that android 6 rom

snce their version of Android 6 is compatible with the version I currently have in the context of fixes and changes.

so i need to know of sure that,

i can downgrade to the original MCU that i mentioned earlier,

in case the process goes wrong.
[MTCD Android Head Units General] typos1:
Forget ROMs, the MCU has nothing to do with ROMs - ALL ROMs from any MTCD/E manufacturer are compatible with ALL MTCD/E PX5 units.

You need to read the thread and see if any others have gone from CHZ to HA, if no one has successfully done it then you are the first. Have you found anyone who started out with CHZ and gone to another manufacturer ?
[MTCD Android Head Units General] stale86:
I have not found any information about changing from CHZ to HA, if it can be upgraded and after it,

I can still downgrade if the HU are not stable in case of mismatch problem,

I do not see a risk here.

I understand right? Im missing something? ?
[MTCD Android Head Units General] typos1:
You need to read ALL the thread and see what MCUs anyone has flashed on their CHZ unit FIRST, if no one has then you will have to be the first to try.

[MTCD Android Head Units General] typos1:
Xtorns just a reseller, they buy units from several manufacturers and sell them as their own, so their are Xtrons units with different MCUs, you can ONLY identify a unit by the MCU, not by manufacturer. Sometime the resellers model number can help also (assuming all units with that number are bought from the same manufacturer.

It is this thread you need to read, not another one, this one !

The Eonon ga9263b mcu MTCE_HT_v3.03_1 is compatible with an Xtrons tq709ipl MTCE_gs_v3.67_3 for an SOM exchange

Took the Xtrons Px6 and put it in the Eonon ... no reprogrammation needed in my case, not fully tested

Just done an factory reset ...

My 2 cents ;)
[MTCD Android Head Units General] typos1:
No need for a factory reset - theyre all HCT SoMs and are therefore all interchangeable, this applies to all MTCD/E SoMs.

Unfortunately not an MTCD/E MCU.

You could try posting in (Android Head-Units) forum.
[MTCD Android Head Units General] jhony benitez:
I would need some help to understand how MCU cross compatibility work, and if I can upgrade my unit.

I have MTCD GS V3.40 on my head unit.

I've been searching in cross compatibility forum thread... if I understood correctly (I would like to know your opinion) it seems that GS MCUs are compatible with MX MCUs and not only but also with MTCE MCUs.

Searching I have found some options that apparently seem valid to use without breaking my head unit:

- A MX MCU found here https://xdaforums.com/attachments/mtce_mx_v3-71-rar.5220641/

- Some GS options ,but instead being MTCD are MTCE https://drive.google.com/drive/u/0/folders/1KEUd6JnRmDlXgopyE9LOX7CF51Ujo3WU

Could I install any of them without risk? (of course I will export first the original file) and if so, which one do you recommend me?

PS. I've tried to access to this link http://xdaforums.com/wiki/Hui_Fei_Type that some of you recommend to read ,... but unfortunately doesn't work.

Thx for your help ;)
[MTCD Android Head Units General] marchnz:
Why upgrade? What specific issue are you wanting to resolve?
[MTCD Android Head Units General] typos1:
Why dont you just flash the latest GS MCU ??
[MTCD Android Head Units General] ThaCo98:
Hello guys, i have a PX30 head unit with installed the latest MTCE LY 3.65, i wondered if this kind of mtce was cross compatible with some like maybe GS or MX. Thanks to who will answer me

Cheers:)
[MTCD Android Head Units General] marchnz:
What problem are you wanting to solve?
[MTCD Android Head Units General] ThaCo98:
It was just curiosity, because the LY MTCE was not mentioned above the cross compatible
[MTCD Android Head Units General] typos1:
If no one has tried it in this thread then you ll have to try it yourself, but if you have no problem to solve or no function you want to obtain by changing the MCU to that of another manufacturer, then why bother ?
[MTCD Android Head Units General] jhony benitez:
Not specific, but if heard new upgrades allow to use some buttons for o couple of actions, ie. play but if sounds phone you can press play to receive the call
[MTCD Android Head Units General] jhony benitez:
It is the one I'm using
[MTCD Android Head Units General] marchnz:
Is there a problem with the current MCU, I don't understand your other remark, you can assign dual actions to buttons, just not canbus buttons without mods.
[MTCD Android Head Units General] typos1:
So youre using the latest GS MCU and you want the latest GS MCU which you already have ? Doesnt make a lot of sense.
[MTCD Android Head Units General] jhony benitez:
There is any problem with it, and of course you can assign short and long press, but I've heard there are new MCU firmware that allow double action with short and long press like this
[MTCD Android Head Units General] marchnz:
Thats not an MCU, it's mtcd-utils. So install mtcd-utils? Or install a ROM with the mod included?

Like I said, you can do just that today, with SWC non-canbus. For canbus, you need to install the rom or mod. You still haven't said if your unit is using canbus or not, but either way, an MCU won't help you.
[MTCD Android Head Units General] jhony benitez:
Understood and clear.... my unit isn't canbus I will try to do it with mtcd-utils

Thanks!!!

I would like update MCU to version MTCE_KGL_V_3.01_5. I have seen in a video that solve my problem.

Thank you very much
[MTCD Android Head Units General] typos1:
All MTCD/E units have the same STM32 chip.
[MTCD Android Head Units General] moreno_cos:
Can I test/upgrade to MCU KGL or do I run the risk of bricking my radio?

Thank you
[MTCD Android Head Units General] typos1:
You have to read the thread, if you can find someone with an XRC MCU who has successfully changed to a KGL one then yes, if not, you will have to experiment yourself. Make sure you export your config before trying anything.
[MTCD Android Head Units General] moreno_cos:
Thx, I understand now.

My Original Mcu: MTCE_XRC_V2.80_1

I have installed all of the following MCUs ( 100% compatible) but it has not fixed the problem:

- MTCE_GS_V3.17

- MTCE_GS_V3.30

- MTCE_GS_V3.44

Canbus
[MTCD Android Head Units General] typos1:
The CAN Bus decoder is either wired incorrectly (you may need to change some wires or swap some of the plugs on the CAN Bus loom) or the incorrect CAN Bus version is set in factory settings.
[MTCD Android Head Units General] marchnz:
Thanks for sharing your experience. Did you also upgrade Android to the latest HA?
[MTCD Android Head Units General] basmand:
Hi

Take a look on this post, just installed MCU 2.51_1 on my GS (XTRONS TB706APL) unit whitout any problems.

HU: Xtrons PF75OLOA

Orig MCU: MLT 2.05_1

Updated to HA 2.52

Result: Everything else works except Radio, it will never tune to channels. (and cant find any channels)

(PF75OLOA has different Radio chip than 'normal' MTCD Headunits)

So my personal suggestion is NOT to do this update for PF75OLOA.
[MTCD Android Head Units General] typos1:
Have set the correct radio tuner type in factory settings ?

(BTW you do not have an "Xtrons" you have an MLT - Xtrons are resellers only.).
[MTCD Android Head Units General] marchnz:
This is to be expected until you set factory settings.

Did you remember to document and set all of your factory settings?

Specifically set [radio = yes]

These units are all based on a reference design.
[MTCD Android Head Units General] marchnz:
.delete.
[MTCD Android Head Units General] AndHead:
Yes I have set and made factory settings manually and also restored them. (I have two PF75OLOA head units, one PX3 and one PX5, so I can easily cross check what works and what not)

(And yes, I have 'Xtrons' PF75OLOA as I bought it from them, sorry to disappoint you about that ;) )

---------- Post added at 22:26 ---------- Previous post was at 22:24 ----------

Yes, did so. (Manually and restoring from cfg file)
[MTCD Android Head Units General] typos1:
You may well have bought it the retailer called "Xtrons" but that DOES NOT mean its an Xtrons unit, its an MLT unit made by a company called MLT, Xtrons buy them and stick their badge on it, this DOES NOT make it an "Xtrons" unit, it makes it an MLT unit with an Xtrons badge on it.
[MTCD Android Head Units General] marchnz:
Thanks for sharing your experience. Your unit isnt an xtrons as [MENTION=456516]typos1[/MENTION] points out, it is an MLT. To say it is an xtrons is not correct because Xtrons simply drop ship / resell.
[MTCD Android Head Units General] AndHead:
I understand your explanation, but I still say from my point of view it is 'Xtrons' PF75OLOA.

Stating it as 'Xtrons' PF75OLOA is much more informative than just saying 'I have Android head unit MLT'

(Notice that I gave the MCU info right below under reseller/model number, so could please accept my point of view. I provided all details required to see what my head unit is)
[MTCD Android Head Units General] typos1:
No, its not more informative, quite the opposite - all it does is create confusion, its much better if everyone knows them by the name of the manufacturer, not the reseller. After all, if you bought a BMW 3 series from a dealer called "John Smith BMW" would you have a John Smith 3 series or a BMW 3 series ?

Around here we call out units by their manufactuter's name and their MTC type, ie you have an MLT MTCD unit.

And I know you gave the MCU info as well, all I did was add a note at the end of my post to inform you about it, I didnt want a debate :)
[MTCD Android Head Units General] AndHead:
Again, I understand your point of view very well :)

But let's say somebody else wants find our more details about my head unit, so using your analogy: google 'BMW' and you will find lot's of BMW car models and details for them. (And hopefully finally the one you were looking for info for)

Now google 'MLT Android head unit' and how many head units you get, and which one of those is mine? :)

(vs. Xtrons PF75OLOA or just 'PF75OLOA' works fine)

But again, I understand that mine is not manufactured by 'xtrons', but calling it with reseller + model name should not cause this kind of flaming as I clearly provided the MCU details for it too.

(Oh btw, it has now MX PX5 board, so is is now really MLT? or should I now call it MLT+MX Head unit to be correct according to the naming standards you are telling me about? ;) )

I will stop this here and wish you a nice evening/morning/day(night from wherever you are, just wanted to share my experience with my MLT+MX head unit.
[MTCD Android Head Units General] Carignankg:
FYI

My head unit MCU Version reads like this :

MTCD_KLD_V2.50_1

I think that means that the KLD MCU is compatible with MTCD? am I right?
[MTCD Android Head Units General] typos1:
I simply added a "BTW" to my post, just for info, this is not "flaming" at all, ironically the way you responded IS flaming.

My analogy stands up because "3 series" is analogous to "MTCD" (there also being MTCB and MTCC units in the family) so people would google "MLT MTCD" not just "MLT".

The SoM is not relevant. at least for this thread, though usually if people mention the SoM they would say "PX5 MLT MTCD".

Take a look round the forum going back three years and your ll find that this is generally how we refer to them.

Nice interacting with you :)
[MTCD Android Head Units General] martyuk:
I did upgrade the Android aswell, yes - and also tried one of the Malaysk ROM's on it - but still no different. In the end I went back to the 2.43 with the latest GS Android that I could find - though I don't think that was as new as the one that shipped with it, as I was missing the DAB+ app and the install of Torque that came with the unit. I downloaded and installed the updated DAB+ app from the PX5 discussion thread and that all works ok now... I still have a few kinks to work out though - the reversing camera trigger input doesn't seem to do anything - the camera I have works, as I can enable the 'front camera' (which isn't actually wired in on mine, but lets you toggle in the app between front/rear camera) and switch to the rear camera, with the vehicle in reverse and get the image of the camera up onscreen - but the 12V trigger wire into the head unit doesn't bring it up automatically onscreen when I select reverse. Also having infamous wifi problems... even with adding the second antenna port to the PCB and fitting 2x 5DBi antennas.. seem to get reasonable signal on wifi-scanner app (same as my phone gets with it's internal antenna in the car) but where I'll get 10mb/s on the phone, the PX5 either won't connect - or the time it did connect, I only got 1mb/s

Thanks for that - I'll take a read through now - I'm hoping that updating might iron out a few of the niggles...

I put a post up on the Xtrons forum about the reversing camera and not triggering but it's still "Pending Approval" so I'm not holding my breath there either!

I'll have a play around this afternoon and see if I can get the later MCU installed and behaving!

Cheers!

Hi guys,

I have a problem, i got Sofia3gr, MTCD_HCT_V1.181_1 with 2gb ram, my seller send me wrong MCU update file, should be HCT and he send me XHD MCU, i did not know this before and i did update wrong file, and now my volume knob is not working, instead volume up and down it does next track/next station.

I'm not sure that's the problem.

I have read cases that with android 5.1.1 it worked correctly, and new units with 7.1.1/2 did not show data on the screen and did not work all the SWCs

That will no help as the SWC is controlled by the MCU and the CAN Bus decoder.

Hello everyone,

I recently bought an Android PX5 radio for my Peugeot 407 https://www.zonteck.com/products/Zo...*0_Peugeot_407_Car_DVD_Player_Multimedia.html

The radio has the MCU MTCH_MX2_V3.84_1 and I have several problems:

The first problem is that the radio does not have the APP of the Air Conditioning App AC (it simply does not have it and the seller does not clarify me why).

The second problem is that the automatic light switch does not work.

Can someone please help me?

Maybe an update?

Is it possible to get the AC App separately?

Can anyone tell me which manufacturer this radio is from? There is no doc or page with the manufacturer so that I can contact them...

Thank you very much for your help.

ATTENTION!!! If you try to update the MCU firmware of your MTCH platform radio with firmware from another MTCD/E platform, be aware that these platforms are closely related from the same developer, but still different (the MCU microcontrollers are different and the MCU firmware is different) if you be lucky the update will fail otherwise the include will stop working. The MCU can only be repaired with the help of a programmer. You have an MTCH_MX2_V3.84_1 MCU, so you can only use the MTCH_MX2 update, unfortunately yours isn't anywhere yet, try writing to the seller or you will have to wait for someone to add it here. I think you have a bad canbus adapter, or you don't have the correct car type set in the factory settings. Or simply your car is not supported. Sometimes it is better not to have these features than to destroy the device with mindless updates.

There is something here:
