MTCB/C/D/E MCU based units? - MTCD Android Head Units Q&A

Hello Everyone,
I am currently looking for a 10.1 Android Unit that has the MTCB/C/D/E MCU. I have a tesla unit in my Tundra now but have been contemplating on switching back for a while due to the features i miss. If anyone can post what brand and models have the MTCB/C/D/E MCU it would be much appreciated.

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?

a bit if hot air and the correct LEDs should be an easy modification.
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?

He d probably have to re-write the app as it talks to the MTCB MCUs.
Is there any prerooted, more recent Rom for"MTCD_LM_V1.40_1" (03/30/2016)? Thanks in advance.
Headunit is made by Erisin LM. Android 5.1.1. RK3188

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??

10.1" C800 Px5 Ownice or 7" PX6 Sadocom/Shyshadow

PX5 Ownice: https://www.aliexpress.com/item/32866194275.html
PX6 Sadocom: https://www.aliexpress.com/item/33001539722.html
Price difference isn't that much of an issue. On one hand having the specific vehicule model with adapter helps, on the other hand having some physical button seems nice.
PX6 sure is faster and more future proof, but is an increase of speed really going to change anything?
There's also the fact there seems to be more people using the Ownice unit and it being a more reputable brand from what I understood.
If you have any other input, please let me know, I'm pretty conflicted right now.
Edit: Okay, since I'm at it, there could be a 3rd model: HA2014-V840-8 Dasaita PX5 model with added DSP https://www.aliexpress.com/item/32829488840.html
Good brand, as cheap at PX6, lots of buttons, but I'd have to play with wires like the PX6.
What happen?

What do you mean?
If you ask me don't think too much of the future, the large screen and custom fit frame is nice just enjoy your unit until it dies of defective soldering then you'll be ready to replace it with the latest model.

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

Head Unit Recommendation

Hey there!
I'm new to the Topic of Android Head Units, and currently looking to get one for my Kia Ceed SW from 2007 which doesn't even have Bluetooth right now, so i'm looking for some help here. My Budget is around 200-350€ max. and i'd like to get something which would work with my steering wheel buttons. I thought about getting a 7" Unit because i'm not sure if 10" would fit. Shipping from germany would be a + for me, so i don't have to wait long.
I thought about getting an RX6 so i could use the Hal9k stuff, because it looks nice, and i like switching firmwares from time to time. But at the moment everythings still completely open. Every opinion would be greatly apreciated.
Thanks in Advance,
Tho
Do consider a uis7862 FYT (e.g. as sold by navifly/mekede, not endorsing either) they are miles better than the MTCD based units while cheaper than even the most overpriced Dasaita MTCD. A bonus is they sound significantly better too.
You won't regret it, it's the software and the hardware improvements that make a huge difference.

Hey there! Okay, sounds good. But where would i get a unit like that? I think all the ones from Amazon are MTCx ones.
Edit: I did some googleing and the ones from www.joyingauto.eu are not really declared which board it is. Or am i doing something wrong?

Question Idoing...

Hello everyone,
I hope everyone is doing well.
Guys, I am so so new at Android Auto head units so I need a lot of help. There is A LOT of information scattered everywhere and somewhat confusing for someone new like me. With that being said here is my question...
Best and latest Doing HU for a 2019 Subaru WRX STI base w/o navigation. I've seen different options and also different prices. Before I pull the trigger on the unit I would like to make sure I am getting the correct unit for my car, the latest unit, with the largest screen, and the most powerful/ fastest unit available as of today.
The main feature I am looking for is wireless Apple CarPlay, and to retain factory functionality of steering controls and stock unit.
Guys, thank you very much in advance to answer all my questions in advance!
Cheers,
Javo

Hi,
Idoing is a made up brand name and seller of various Chinese factory head units.
Is it an FYT based unit being considered, as you've posted in the FYT forum.
Be sure to get details from sellers with screenshots of the unit - this way you can find out what it is you are considering, check the info here and then ensure the unit is what the seller said it would be.
Narrow it down after reading the forums.
