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
Sent from my SM-N920C using XDA-Developers mobile app

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?

There is already an deprecated app for 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??

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.

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

Click to expand...

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

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?

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.

Question Looking for recommendations

Hey All,
Currently, i have the jy-vm131n2 Carjoying (https://www.amazon.de/JOYING-Volkswagen-Touchscreen-Navigationsträger-Rückfahrkamera/dp/B072XG5CR2) installed in my 2007 Seat leon.
Unfortunately it start to give up. Therefore im looking for a new device.
I havent been around here for a while, no idea whats the current "state of art" on new Headunits.
Ive looked on the Joying Homepage but it seems like they dont have that much of Headunits for Seat.
My requirements for a new Head Unit would be:
-Full Touch as my previous device
-same form factor
-CarPlay for IOS (or at least be able to use my carlinkit cpc200 pro dongle)
-fast touch responses
What are the Brands to look out for at the moment? Can someone may give some recommendations?
Thanks!

Looking for recommendations for an FYT based unit?

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?
