Q&A MTCD Units

Where is the source code?
A: It is not released, nor will it be released as it was with mtcB. WTF!
Do the MTCD boards have proprietary hardware and/or software? Besides the MCU
A: Yes. Custom digitizer means you have to buy screen from them. LCD is generic so its replaceable but I have found a reputable dealer. Heres website
http://cowinlcd.com/html/en/index.php?ac=article&at=read&did=113
What are the LCD and digitizer model numbers?
A:depends on the head unit model
10.1 inch version: Cowin and goodix
7 inch versions: ?
Where can I find rk3188 2gb boards to replace the 1gb board?
A:JOYING-There are none. They keep claiming 2gb is coming, but if they knew MTCB boards were slow with 1gb, why are they selling it again.
A:Xtrons-
How are they loading the software onto the board? (Jtag etc)
A: from Rockchips site,
"Support system code download by the following interface: USB OTG interface. | UART2Interface "

Then I'm assuming(NOT TESTED) we can use rktool and flash the update img. Tearing apart the img shows partion paths. This might be the method for user recovery on hard brick units.
Has anyone found any suspicious activity/service/app running on these units?
A: Not yet but since source is being withheld BE CAREFUL of your privacy.
Has anyone used any after market shark fins with these units?
A: Only Radio fins was tested. GPS fins unknown. LTE fins known.
A guy pm'd me an app that sets Poweramp as the primary music player and adds it to steering wheel controls, however the app is specifically for poweramp unfortunately. However, if someone has managed to make it work with power amp, i cant see a reason why it couldnt be re-worked for Google Music?
A: Joying and other brands dont care or have much knowledge. The lack of source code is sad. Its left up to the users which begs the question:
Why is this product so expensive if it runs extremely slow and we have to do all the work?
A:
Is there any way to pull an image of the full MCU/stock software for recovery purposes, or is this one of those things that is really available only from manufacturer?
A: Yes . Online Nandroid on play store. or RKtools.
Where can I get drivers and other useful tools?
A:Rockchips site
If anyone else has questions that get answered here Ill update first post to reflect it.

android system/bootloader/kernel How are they loading onto the nand storage. With certain phones and tablets you can jtag. Others require certain hardware or software to load it onto the board. This is to try to come up with a user method of recovering hard bricks.

Can anyone with experience of MTCB units and MTCD units post some sort of comparison of the two types ?
We can see what the differences are but it would be useful if someone with experience of both types ( @Marius B or @doctorman maybe) could post some comments explaining the hands on advantages or disadvantages compared to the "B" units.
Maybe even open a new thread on the subject of the differences and whether its worth upgrading to the "D" types.

I have seen a question about malicious apps/activity a few times on the MTCD board. Was that a problem on the MTCB units or another? Or are you all just doing due diligence?

what kind of detail do you need.
there are reviews around the net on both..
to my experience right now the mtcD ROM needs major polishing , it is nothing close to mtcB. it is sluggish.
I am so sure that I noticed one boot at 10 seconds but could not replicate it, I am getting 23 seconds boot time on mtcD with latest Joying ROM.
motherboardis rearranged,
it has now 3 UPS plugs on the mother board, only 2 used.
2 wifi antennas but wifi is still 2.4 GHz
GPS antenna is soldered to the coreboard instead of motherboard.
the screen ribbon cable in mtcD is narrower and does not fit the old mtcB connection
touch screens are not interchangeable even though the cable is the same
BT is built in to the motherboard now
I would give the mtcD 6 months to mature up like mtcB units
we now have many developers working on head units and they are joining mtcD as well and bring their work over to these so it will hopefully go faster.

Thanks Doctorman, I think its pretty obvious that MTCD will replace MTCB, a shame in some ways cos of all the work done on MTCB units over the years, it would have been nice to be able to just upgrade the SoM as we did from MTCB RK3066 to MTCB RK3188, on the other hand the MTCD MCU seems to be better then the MTCB MCU and lots of the MTCBs bugs seem to have gone with the MTCD units, its just a case of allowing them to mature lke you say.

I need the steps in order to root my device

Does anyone have an MCTD device that has working bluetooth settings? Can you add and remove devices freely without issues?
The rom that came on my device can't add/remove bluetooth devices from the head unit bluetooth settings page. Selecting a device does nothing. It's as if you don't pair a device once initially prompted, it won't let you change things.

I do, but only phones and OBD2 dongles pair so far. Also most apps other than Torque that would use the BT obd2 dongle think that BT is off in the system.

I bought a Huifei unit for my VW Crafter (I can't post links yet due to my post count, but if you search for Crafter quad core android something like it comes up). Since it is essentially the same as the Mercedes Sprinter, it fits both cars. However, on the VW the dash lights are red and on the MB they are orange. Apparantly when switching to 5.1.1 they also made some hardware modifications. One of them being that the button lights aren't RGB anymore, but only orange. I've already tried to resolve this through the seller by obtaining a new button pcb with red leds, but that seems like a track that doesn't really lead anywhere.
Since I see many people doing hardware mods on these units also, I was wondering whether this is a mod that a local electronic repair shop could do. I've contacted one of them, but they didn't want to do it because they feared the SMD-technique.
I hope you guys can confirm that this is possible to do by a professional repair shop.
BTW, I know I'm to late to the show to sponsor the new unit for the 5.1.1 development. But I would like to show my gratitude to this person anyway, since I'm really hoping the software side of things gets improved soon also and I'm very happy that he is willing to take on this task. How can I still donate to him?

Hello
Whether at this moment is possible to configure wheel to sterring in custom aps like a spotify etc.? I have mtcd for bmw and in my Steering wheel keys app dont see any keys.
Or We need to new custom firemware or app updates?

Just make use of the "phone" app, you can delete paired devices there!

There is already an deprecated app for this.
Maybe the developer can help us with this?

No, your head unit is NOT made by Erisin, Erisin are a seller.
Go to settings/about device and see what 2 or 3 letters appear after "MTCD" in the MCU field to find who your manufacturer is.

Can LM Boards be used with some other manufactors roms likely "rebranding"? (or will this cause a soft/hardbrick?)

I flashed on my KGL Unit a Joying Rom. Just the Rom, not the MCU!!
Works without problems.

Can anyone tell me if the modded apps like Bluetooth and Radio for the MTCB units work on MTCD units??

What's The news in Android HU scene ?

Hi guys
So in 2017, I bought an Andrid HU with an Intel Sofia SoC ( Joying JY-VM130N2D) for my Volkswagen.
It still works but there is some annoying bug and now i'm quiet bored of that. So I want to know what's the news on the Android HU scene.
-As I remember, the Intel SoC can boot approx. 5 sec after turn on the car and the RKXXX is always 30 sec ? How it is now ?
-Now I can see PX6, MTCE etc... what's the updates between the old one ?
-What's pro and con's between Intel and Rockchip ? It seems, there is more people who develop on RK than Intel
-Which company I should use to look for a new HU? Joying seems to stay with Intel Soc and i Don't know the brand like Xtrons, EUNAVI...
Cheers guys and happy new year !!

Perhaps tabulate from questions, not sure owners of one head unit will know how the shyte JY units compare to the MTC units.
Perhaps read the wiki and compare against the rubbish Unit you have.

Thanks I was looking for a wiki I looked in the wrong section ^^

As I understand it the current market is still Intel vs rockchip.
With RK you're still at px5/px6 which as you say, have really good community support.
Px5 and px6 headunits have come a long way. Boot time is 30 seconds from cold boot and less than one second from standby, which is the default state that the unit goes into when you turn off your car. Power drain in this standby mode is negligible and I've left my car without starting it for 3 weeks in this mode.. car started right up as did the head unit.
Biggest issue with the px6 headunits right now for me is the internet.. basically the WiFi on these units is still crap regardless of the brand you try, no matter what anyone tries to tell you or clever hardware hacks you try.
And if you want a dedicated mobile line you're forced to rely on a 4g dongle or your phones hotspot as the tablets dont support native sim cards.
The 4G dongle solution is also passable at best, after a lot of fiddling and some software level hacks. (See my post about 4g dongles on these units for example)
On the Intel side, there are new airmont based HU (sc9853i) with dsp and native 4G sim card support.
These are pretty good and are quoted to be 30% faster than their px6 counterparts.
In my opinion the biggest issue with these is not the lack of community support but how they fit in cars. Basically where the tablet attaches to the headunit is just a push tab that's not adjustable. Comparing to the px6 counterparts which are usually rotatable or at least adjustable up and down
https://forum.xda-developers.com/an...ying-android-8-1-intel-airmont-eight-t3897206
Also worth noting in the px6 world is the new Tesla style headunits. They're a little more expensive but 12.9 inches and seem to have excellent community support with a dedicated, active Facebook page. They seem to still have the PX6 issues with 4G internet though their WiFi antenna doesn't suffer from the same Bluetooth interference that the other units get.
https://forum.xda-developers.com/android-auto/android-head-units/tesla-style-headunits-t3512709/amp/
https://m.facebook.com/groups/tesla.style.FW.HU/
For my money, the perfect headunit that I'm holding out for is 12.9 inches with rotatable mount like the Tesla units but using airmont hardware with the native 4G support.
Of course, all of the above is my opinion only gained through my own personal experience with each of these units. Its entirely possible that someone else's experience my contradict mine. Also, the market is vast and I think I did a good job combing it but it's very possible that I missed some other type of headunit. If so I'd love to know so I can see if it fits my needs.
Hope this helps!

Thanks for the info.
I was looking for Tesla style HU but I think it won't fit in my car and it's quite expensive.
What i'm looking for now it's the dasaita MAX6, which seems to be the best product. I see a lot of other product which correspond for me but i'm quite sceptic about the quality of these and dasaita seems to be a better choice.

General New Joying Android 10 UIS7862 Octacore 1.8GHz (4GB RAM, 64GB flash)

EDIT: XDA didn't like me attaching the photos, just got broken links so I'm sorry that they're embedded like this.
Joying just sent me a review unit of their new 10.1" Android 10 head unit so I figured it should have its own thread. It looks like they're pumping out updated versions of all their previous devices by the day so I imagine they'll have versions of this in all the different screen sizes soon. First impression is good. The interface is appreciably more responsive than the Intel unit I currently have in the car. I'm working on some videos but figured I'd throw some pictures in here. Here is an unboxing and interface tour video: https://youtu.be/h__Zc0fwOtw
The PCB looks is clearly iterative but looks to have some significant redesigns, especially with the power supply which is much larger than on the previous Intel design, through that might be required for extra derived voltages for the new UIS7862 SoC.
The previous Intel PCB used an STM32 MCU in between the main SoC and the bluetooth module which probably contributed to the difficulty interfacing Bluetooth devices that weren't specifically allowed by Joying. The area where this chip was now looks to be filled with power components though the same Bluetooth module is still used. I'm hopeful that this means there's direct communication from the SoC to the BT module, but that'll take more digging to determine. There is also a new general purpose ARM Cortex-M4 MCU added between the SoC carrier board and the DSP chip (GigaDevice GD32F330R8T6). I'm curious if that's taken the place of the old STM32 chip or if it's used for something else. Hopefully I'll be able to determine what it's used for, but I'm not touching anything until I get it installed and reviewed.
The green PCB is the Intel board and the yellowish one is the new Android 10 board. Of note is the fact that the new PCB has Joying's name silk screened onto it where the old Intel one didn't. So, at bare minimum, this board is spun just for Joying, even if the only differences are the silk screen layers.
Any requests for specific details?

Increased BT functionality would be huge (by hack or otherwise).

I'm just curious about:
- How's the WiFi speed, especially in combination with Bluetooth switched on and your phone linked (was absolutely terrible on the SC9853i's due to combined frequency/bandwidth use)
- Does Google Voice work with phone calls?
- Has CANbus functionality improved? Especially: does it now support 2-way Airconditioning control? (previously it was only possible on Ford AFAIK to also raise/lower temps from the Airco app)
- which launcher do they now use/include (do they include the T'eyes launcher or some look-a-like?)
- And like you already mentioned: what can be connected via Bluetooth? Still only Joying/FYT "allowed" hardware?

I'll work on these today and tomorrow but I can answer the launcher question. Thus far it looks identical to the launcher on my current SC9853i unit with the exception of a slight tweak to the EQ app which adds the ability to set a Q value for each of the fixed frequencies.

So I'm looking at buying one of these new Android 10 Units.....Seems like they have a 7" Version SKU: JY-UQS03N4G with the Dual ARM Cortex0A75 but cant verify its the same hardware.
I currently have the PX5 Android 8 version.
So Im wondering the following:
So hows the sound quality?
The Android Auto/Apple Auto working? I know there were issues with the version I have
How fluid/Quick is the touch screen?
Any negatives you have noticed so far?

I can answer most of the questions in the next day or two when I get it installed in the car, but I'm pretty sure that it is the same hardware. From what I've seen they just slap different screens onto one or two head unit bodies (not sure what else to call it...) and that has the same 2x A75's and 6x A55's but also includes the 4G module that mine doesn't have. Looking at the PCB I really wonder if the radio isn't already there and they just don't populate the antennas and remove the mobile data option from the firmware.

I put together an unboxing, initial impressions and quick interface tour video: https://www.youtube.com/watch?v=h__Zc0fwOtw I'll have an install video coming out soon and a full review. This has been my first experience trying to make videos like this where I actually have to talk so I'm still trying to figure out how to put them together and how to not stumble through all my words
First impressions of this unit are very positive, though I'm expecting to be more critical in the full review once I've had time to test everything out. I laid into them in my review of the Intel unit I bought for a bug that resets all the trip computer units to metric every time it reboots so I was surprised they sent me a review unit . I'm hoping that bug is fixed, but I highly doubt it. I'm really interested in seeing if they managed to eliminate the slight hiss (EMI) when nothing is playing and it's not muted. The expanded power might help with that, as well as the fact that the SoC carrier board has shrunk and there is more clearance between it and the DAC output traces.
The first bug I ran across is a small one, but it's very difficult to swipe away and close apps in the recent apps screen. Like, you have to grab it at a very specific spot on the icon and drag it all the way to the edge of the screen... That strikes me as a strange one but it's actually somewhat infuriating so I hope it can be fixed.

I believe the CPU on this board is the Unisoc Tiger T618. Its specs most closely match the specs that we already know, except the 2 Arm A75 cores are supposed to be at 2.0GHz stock. The T618 is a 4G chip so the modem would be built in, but disabled via config file. You could solder on the antennas and also solder in a SIM tray and then enable the modem and it should work. I've already learned that the chinese resellers will cripple their devices to sell "features". Teyes is a great example, they will disable certain bluetooth features unless you pay for the more expensive model. I believe the resellers have few versions of boards, mainly ram and storage difference, maybe DSP difference, but that's about it. It is their decision to disable/omit 4G only to sell it in a more expensive model. It is not like regular phone manufacturers that will disable features via efuses or different chips.

Joying/ joyus simply reducing manufacturing costs and maximising margin/profit.
I could be wrong but think these will be mostly a port of previous code, complete with old and new bugs but on "cost effective" hardware.

I'd also assumed the 4G functionality was already included, simply because of the cost required to have multiple different parts. The antennas pads are kindly labeled on the PCB and there's already a header for the SIM tray so no soldering required for that part, assuming the pinouts are the same. I'd be interested in trying it if someone were able to figure out how to edit whatever files are required to enable the functionality in Android, if it's possible. I've even got the SIM tray and antennas from one of my units that I broke so the swap would only take five or ten minutes.
he Bluetooth on the previous version had a separate STM32 MCU in between the main SoC and the Bluetooth board and I'm pretty confident that was acting as a gatekeeper and is what prevented us from easily adding functionality. That chip isn't present on top layer of the new PCB but it could be hiding on the bottom. I'll find out when I pull it all apart (after I get it installed and do the review lest I break something)

I remember in the sc9853 thread there was mention of a crruptoff file you place while flashing to basically disable the no sim card message if it's missing the sim card. But I'm thinking that configuration information is stored inside the fytdata partition that the resellers pretend doesn't exist.

Love your reviewing everything. I went ahead and ordered my unit since it has to come from China and that will probably take months.

You'll be surprised. Each of the three units I've ordered from them have come in (Minnesota, USA) exactly one week from the date of order, though I imagine that may be a or two more depending on where you live.

All mine have come from the Chinese warehouse. Two have come via DHL and one via FedEx. DHL is especially fast. The darn thing will land on the east coast at 4am, then make it to Minneapolis by 10am, and by 11am it's on a truck for delivery. That's been my experience with them every time I've ordered things from China with DHL.

I remember in the sc9853 thread there was mention of a crruptoff file you place while flashing to basically disable the no sim card message if it's missing the sim card. But I'm thinking that configuration information is stored inside the fytdata partition that the resellers pretend doesn't exist.

This worked in the previous PX5 Firmwares and early SC9853i firmwares, but it no longer works.
I assume they removed the check for the file.

I'll investigate, but I did see in SystemUI that it checks for fixwifi to determine whether to show or hide the signal bars.

Progress! Thus far I can confirm that Bluetooth is still locked down and the "call xxxx" Google assistant bug is still present.

I can imagine bluetooth being forever locked down since the apk does all the checks before allowing a device to connect.

General Teyes cc3 or navifly?

Looking to buy one or the other.
Can anyone tell me which one is better to root.
Also I like that navifly has 5g wifi.
I'm rocking a pixel 3.
https://www.aliexpress.com/item/1005001652626325.html
https://www.aliexpress.com/item/1005001948289474.html
Thanks for the help.

They are both FYT based units. Rooting should be 100% identical.
There is no 5g wifi. There is the new 5G mobile network and there is 5 GHz wifi (or 2.4 GHz wifi).
Both do NOT support 5G, and both do have 5 GHz wifi.
Like said: both are produced by FYT including the Android layer and builtin apps. T'eyes and NaviFly are only resellers where T'eyes probably has by far the best support and most probably the better quality control, but is also more expensive.
Those resellers only vary in 2/32GB vs. 4/64GB, DSP or no DSP, STN or IPS or QLED displays, with or without 4G.
Note: the QLED screen is new and theoretically better than IPS (which is again better than STN)

Thank you so much for your help.
I'm still a tad confused though.
It would appear that the navifly supports 5ghz wifi.
And from my understanding using android auto wireless with my pixel 3 needs 5ghz wifi support.
I don't believe the teyes can do this.
Is this correct? Sorry pretty noob here just asking questions.

Take a look at the Teyes website https://cc3.teyes.ru/
and read the Teyes CC3 topic. All things you ask are mentioned there already in the first post. Do some searching and reading!

Not right away. The T'eyes firmware comes with builtin registration routines to make sure it is a T'eyes unit. Same for T'eyes voice. They deactivate Google Assistant, but you can only use T'eyes voice if you register with T'eyes. That will not work with a NaviFly.
It requires quite some (illegal) hacking of the firmware.
If you really want to go forward with this you need to follow the 4pda forum threads.

Hmm. I really dig the software. Problem is there is no eu shipping only directly from china or russia.. is it possible to activate google assistant in the software

Yes, but it is disabled again on every restart. I used the CC2 software on my Joying sc9853i and enabled GoogleAssistant again (and again and again) using a "boot script" that started with 30 seconds delay. Next to that: all voice "actions" are directed to T'eyes voice which is hugely annoying. Even with GoogleAssistant it is still hugely crippled as T'eyes defaults in everything to T'eyes voice
Also: It is really a demotivation strategy from T'eyes as you can't use any voice software (without hacks), even not T'eyes voice itself, if you did not activate T'eyes voice either. T'eyes is another supplier that does closed-source, protective actions on their hardware. Something many people blamed Fyt/Joying for. T'eyes even takes it a step further. But they do deliver a nicer looking product with good support. And they need to feed their family as well.
So I reflashed my Joying firmware again to my Joying unit.
I use CarWebGuru (paid) as launcher, GorillaSoft folder music player pro for music, Magic Earth (90%) and OsmAnd+ (10%) for navigation, and DAB-Z for (DAB) radio. I hardly even see the other software behind it and even removed some. Why would I install good looking radio, music, video apps if I don't use them anyway. And I don't see added benefit of T'eyes voice over Google Assistant, be it that Google Assistant does not make calls on my Joying unit.
Everyone should decide for him/herself, but don't cripple you unit only for good looks. But that's my point of view and you can decide for yourself.

Hi Surfer, would you mind sharing your boot script, please. I would like to play around with it. I have purchased a Navifly 7862 unit for my Kia Sportage and would like to see what can be achieved.

What are people's thoughts about the Navifly? There is not a lot of discussion about their particular implementation of the 7862 units. I ordered on yesterday and have just been advised that there will be a 12 day delay. This might actually be for the CANBUS rather than the head unit, though.
My car has multiple radio fascia options and only Navifly seem confident that they have my required fascia and their photos seem to show it.
I am curious to know if they cripple Android Assistant like Teyes does. I see you purchase a Navifly voice assistant so I assume that is the case. But that is not a deal breaker for me. I don't use Google Assistant currently.
Should there be a specific thread for the Navifly 7862 to be sure the Teyes thread doesn't get muddled?

@surfer63 compared to the PX5 MTCE i have now, there is equal stability in the basic software (especially google play) and in the management of radio, gps, audio? I am interested in a Navifly 7862 that has an affordable price, in particular I would buy it for the optical and coaxial outputs it has, i want to connect it directly to my Audison AP8.9 . Thanks for answer

Yes, they do. It seems to be the new FYT strategy.

You ask me , but I really don't know what it is compared to an mtce. I don't have an mtce. But I assume the basic software is all equal. Note thhought that until now the RDS-AF does not function correctly on FYT units. I guess the Chinese programmers translated the English specifications incorrectly.
And I am a basic audio listener. My unit is simply connected to my very simple car audio: two front speakers and 2 front tweeters.

is there firmware support from Navifly?

Thanks @surfer63...how is the firmware support from Navifly?
Does it release updates of fw and mcu and where is possible to find it?
Do you think it is a reliable radio?

Reliabilty is not the strongest selling point of any of those Chinese units.
I guess they are more or less basically the same for any manufacturer over the several resellers: FYT as manufacturer in this case.
I also guess that the "mini"-assembly the resellers do, like TN/IPS/QLED screens can differ, but not so much.
The greatest difference could be in support: service desk, firmwares, broken parts, etc.
And I really have no clue there about Navifly.
As I don't have a Navifly I did not look at all for their firmware. And for that matter: Neither for firmware from Kingsbeat, Navifly, Zhan, etc.
And when it comes to firmware: All FYT compatibles on the same CPU, with/without DSP, in the same aspect ratio* can, with some tweaks, run each others firmware.
Now with the new models and new firmwares having protection in the apks, coupled to the MCU it gets more difficult.
*: not resolution, but aspect ratio: FYTs screen layouts in the apks are terribly old-fashioned and fixed: 1024x600 / 1280x730 =>16:9; Other layouts like 1280x480 or "Tesla style" really require a different firmware. FYT currently can only accomodate the several resolutions if the screen has the same aspect ratio. That is also one of the reasons the FYT apps themselves do not support split-screen. A feature they so much like to advertize, but doesn't work for their own apps. A few new developed apps do support this finally.

so..i decided to buy this Navifly CC3 HU on Aliexpress, the price is much lower than Teyes CC3 . Navifly ship the CC3 from Germany , Teyes ship only from China ...with customs duties.

Nice, I am very happy with mine. The navifly does not seem to have all restrictions that I am hearing from other units. But it does have some restrictions.
From China to Australia, mine landed on business Day 5 or 6.

Bought a PX4, not happy. Looking for a replacement.

Hi there,
Recently I bought a PX4 to replace my PX5 radio in my car, a Fiat Punto Evo. The PX5 did work as it should, but I was looking for something new and fresh. Since the PX4 is based on newer technology, and Android 11, I thought this was a step forward. This is an Isudar unit by the way.
However. I noticed the headunit isn't that great. I usually use 2-3 apps (Spotify, Google Maps/Waze and Flitsmeister, a navigational tool for speedtraps and so on) and the radio doesn't perform well when I have these apps opened. Google Maps crashes a lot of times, Flitsmeister freezes and when I want to go back to the homescreen, the screen flickers a few times back and forth. Also, it does reboot all of a sudden.
There is not a possibility to flash or update it since there is zero to little knowledge of the PX4. I'm thinking of the following options:
- Buy a PX6 board and swap it in
- Buy a PX6 headunit
- Maybe there is an alternative
What is a reliable brand in this sector? I see a lot of brands but I don't see the difference...
Cheers,
Jacco

There is no px4 and you don't say if it really is an MTCD type because you haven't posted enough information such as MCU type.
Brands mean little to nothing as the all sell from various factories and are no real "brands" for these Chinese units, only factories.
You want a 7862UIS FYT (4gb+) unit such as what mekede / navifly sell (type 116) These are much less buggy than mtcd type units and you don't need hacky modded firmware to make them work.

Well, there is, it's a RK3566 based one, MTCH_GS_V3.80_3.

Just for clarity, there is no PX4. The unit linked clearly lists PX6.
I no longer recommend the MTCx platform.

Well, actually the details list two options, a PX4 one and a PX6...
But @marchnz is correct in both accounts
1) PX4 is something this guys invented, and is not widely used/accepted (yet). Regarding the CPU they are using, seems to be a slightly improvement/update to the PX5... but very slight improvement (newer tech, more speed per CPU, but less CPUs overall)
2) Even if you go to PX6, those CPUs are old compared to 7862UIS... so buying today a PX6 would be a bad investment. If you really want to reuse the unit and only invest on a CPU board, the only option will be to wait for those manufacturers to adopt the latest chip RK3588 (which has a version RK3588S that looks a lot like a car-oriented chip, even with a CAN bus interface). Of course, you might wait for months and there is no assurance that your MTC-H mainboard will be compatible with it.
By the way, PX5 and PX30 were real Rockchip car-oriented official products. I have never seen any Rockchip original document referring to RK3399 as PX6. I only see this nomenclature on the Android-Auto chinese sites. So, don't kill us if in a few weeks every chinese vendor starts to call RK3566 as PX4

Indeed, I thought the PX4 would be a slight improvement because of the newer technology, but the opposite is true, it's horrendous.
No, a PX6 would be a bad choice. the 7862UIS option would be great but I see nothing which would fit in my car, and waiting for the RK3588 could last a while with the current chip troubles.
I'm not going to kill anybody, no troubles

So, if not reusing the MCU is not a problem for you...what about looking for a 7862UIS with a screen that has the same physical size as your current unit?
All the plastic fascias/stereo-fronts are made (most probably) by the same factory, and then distributed to different radio-manufacturers. Its a very low margin manufacturing business that only works if you do runs with thousands of units produced... is not a business large enough to have multiple providers. So, most probably you will be able to take the fascia of your PX4 and adapt it to any unit (MTC or FYT) as far as the screens are the same size
