Android Headunits, MTCB, MTCD? - Android Head-Units

Hi guys,
New to android headunits so have a few questions:
1) What is MTCB? Is it same as android auto or a fork in the os?
2) why are android versions so prominent in adverts? Like phones can you not just upgrade the os?
3) do people mod the rims or does android auto allow freedom to install say YouTube and play videos whilst in motion? I don’t like restrictions.
4) As an iPhone user what functionality would I lose with an android auto head unit?
5) do I need to get a unit sold as matching my motor to keep functionality of controller stalk etc?
6) what is the huge price range for? Faster processor and ram?
7) any recommended brands to go for?
Thanks

2. Marketing!
4. You may lose some ease of use but gain greater functionality.
5. You are more likely to get a better experience
6. Higher specs, and in some cases more profit for the seller (it is a competitive market)
7. Hizpo, Joying, Eonon, Sony etc etc

1. Refers to the interface board (MCU) that allows the Android "tablet" to run the typical car stereo hardware (radio, DVD, CANbus messages ...) also provides external ports. The letters are what you see in the Android system info under MCU. There's also CSN and FYT and others.
2. As Pxdev says for the reason that there's more support here for them and the Hal9k and Malaysk firmware only work on them.
3. Android Auto is a specification and software that turns a car head unit into a dumb terminal for your phone. Everything you do on the screen is sent to the phone for processing. Not every app is compatible with AA. Not to be confused with a Android head unit. The HU is basically an Android tablet that's connected to a MCU that's connects to the car.
4. Some units have Carplay built in or you can add a USB dongle. Carplay is the same as AA.
5. Depends on what your car's factory radio does. If the climate control displays on the radio you would lose that without a matching CANbus decoder...
6. Better processor and more RAM, added CANbus decoder. Low end processors from Mediatek and Allwinner are cheaper and slower making the HU unpleasant to use.

Buying a Chinese Android head unit

Hello guys!
So, I have a 2005 Audi A4 B7 and I'm thinking about buying an android head unit for my car. So far I have found 2 head units that look somewhat like the factory one, or that I like. They both have Android 8.0 / 8.1, Quad-Core with 2GB of RAM. Now, are these chinese head units generally worth it? I'm really concerned about sound quality (I have an aftermarket amplifier and subwoofer installed). Now I have a Kenwood head unit and the sound output is decent, can't really complain (better than factory radio).
And I have a few questions.
One of the units is made by Mekede (the factory look-alike) and the other one is made by Wondefoo. Has anyone had any previous experience with these 2 makers?
Also, I do not see an AUX IN on these chinese head units. Do the have one? Is it possible to have one? I'd much rather play music over BT, but is generally the connection stable?
Seeing as they are Android, am I able to install 3rd party apps, such as Vanced YouTube ? Or Waze (or any other app that does not come preinstalled) ?
Generally speaking, how is the boot up time on these units?
They both cost around $210. Are they too cheap? Should I try and save up more? Look for other makers? Most of the times I'm going to be listening to music (either via USB, BT - or any way it can be connected to my phone; or YT) while, sometimes, using Google Maps / Waze. Are these cheap android head units generally laggy when multi-tasking? Does it really matter which one I buy, as they're all "cheap chinese products"?
Here are the links to the units:
1. Mekede
2.Wondefoo
Or if you guys could recommend me another one which really is worth the money, it'd be appreciated. I'd like it to have volume knobs, and the factory look-alike is a plus.
I am sorry if these questios have been asked before!
Thank you!
One thing to keep in mind - RAM amount. 1GB of RAM is not enough for these units. I'd recommend 4GB of RAM, but make sure you get at least 2GB of RAM for sure (and even that may not be enough).
Try to find a unit with PX5 (octa-core) or PX6 processor and 4GB of RAM, if possible. Android 8.0 or 8.1.
In terms of sound quality, I too was concerned. I ended up rooting and installing Viper4Android and the sound quality is great. I'm using an extenral amp, but the internal amp sounded good with V4A as well. Viper4Android gives you a LOT of flexibility in customizing the sound to your liking.

Must be a PX5 or PX6 ? Most of the sellers don't list their processor model, just listing it as "octa-core". I'm aware that V4A can give you a lot of flexibility in sound customization (I've used it on my phone for a while)
Do these head units integrate well with the CAN ?
Here are the more technical names (may help identify them):
PX3: Cortex A9 (Quad-core) - 32-bit ARMv7 architecture.
PX5: Cortex A53*(Octacore) - 64-bit*ARMv8 architecture.
PX6: Cortex A72 (I'm not sure of the details - brand new platform)
From what I've seen, most Android 8.0 units are PX5 and most Android 8.1 units are PX6 (brand new). Units with older versions of Android are probably PX3, I'm assuming. Most of these units do not get "official" major Android version updates - the manufactureres just release new models instead of upgrading existing models (but some can be upgraded via custom ROM's).
Personally, I would probably look for a PX5 MTCE octa-core unit with 4GB of RAM. I wouldn't consider anything older than a PX5/Android 8.0 unit - and like I said, I'd recommend 4GB of RAM if you can find it. The PX6 units are brand new - there are no custom ROM's or anything for them yet or anything. They also seem to come with less RAM and storage from what I've seen?!?!
Only way to be 100% sure what you are getting is to ask the seller - they should be able to tell you the processor type and "MCU" type (MTCE-XXX),where XXX is the MCU type. The MCU is like the "go between" between the Andorid OS and the radio hardware (MCU type can be seen under the Android settings menu) - you may even ask them to send a screenshot of the hardware info from the Android settings to confirm what it actually is.
Just a "general" overview of some of the basics - I hope that helps.
Oh - and if you have a CANBUS car, you need a CANBUS adapter. If the seller is selling a unit specifically for your car, they usually include the CANBUS adapter. That will allow your steering wheel controls to keep working and other items.
Yes. That actually helped. These with 4 GB RAM and at least a PX5 cost more, about $350 so I'm going to wait, save up a bit more, because I also need to convert my car from 1 DIN to 2DIN and that will cost me at least an extra $70.
I also want one that looks like the factory equipped one, so, yeah, I'll just wait another month or so.
Thank you for your answers, guys!

I have a mekede unit supposed to be android 8.1..... It's not it's actually 6.0
This was from mekede official store on aliexpress
They are now not answering my messages and unfortunately I didn't figure this out until after the buyer protection time limit had ended.
Just to post an update to my original post... At first, I thought that the sound quality was great. But the more and more I used the head-unit, I found that sound quality was NOT up to par with my previous WinCE head-units. And I also ran into noise-related issues. I did everything in my power to try and resolve these issues (including using external amps for better sound quality), but in the end, I gave up and re-installed my WinCE head-unit.
Unfortunately, from my experience, these Android head-units just aren't up to par in terms of sound-quality and noise-rejection. I had noise-related issues from the LED backlighting, USB devices, wifi and bluetooth wasn't very good either. Hopefully, they continue to improve upon these units, because having the head-unit run a full version of Android is great - but sound quality is also important - and even more important to some (like me). Would be great if the big audio companies starting building full Android head-units (Pioneer, Kenwood, Alpine, JVC, etc).
Since my WinCE unit supports Easy Connect, I can still get the advantages of Andoid for certain things while also having fantastic sound-quality and no noise issues. Best of both worlds. Granted, the WinCE unit is significantly more expensive ($699 vs $350), but just like anything else - in most cases, "you get what you pay for". The WinCE unit that I'm talking about specifically is the Dynavin N7 - and they use high-qaulity sound components. But I also had Rosen WinCE head-units and they sounded great as well (but again, significantly more expensive).
All depends on what is most important to you - software flexibility or sound quality.
My new 2021 PX6 from Phoenix Automotive Vertical Fast Boot OEM fiber option. Had this for about 2 months. I use it with an external OEM AMP. Used in a Lexus.
AMP is not fiber. The unit is a PX6 MCU RL78c (2014 Chip-set) NCHHWY V332-0 , Framework px6-userdebug 9 PQ2A 190305.002. OS 9.
Audio is very good! I love the sound. Speakers: OEM Mark Levnson in the front, 6.5inch JBL GX600C + Sound Ordnance M2-10DVC 10inch in the back.
Tested only with stock HU.
What works on the stock PX6:
(With correct wiring harness)
1. Fast-Boot. After first 2 setup boot-ups, on is instant for 24 hours of nonusage.
2. AC controls work (Cooling).
3. Searing Wheel controls work out of the box on Lexus w/canbus included.
4. Audio player works but not a good GUI.
5. Phone works with Bluetooth.
6. Android Auto is installed and works.
7. DSP Sound works with an EQ and many settings, GUI is good.
8. Most User Settings seem to work. Wheel mapping may stop after Fast-Boot for 5 minutes (bug).
9. Navigation (Google Maps) works, GPS works.
9.5. Maps works Off-Line in Google Maps.
10. Radio with about 16 memory storage.
What is not working in a Lexus / Toyota :
1. Factory Settings. All-access is denied. Locked out! Big Issue for me.
2. GAS monitor/usage. This should work out of the box. Phoenix says it is not working and is disabled in Lexus. BUT is advertised to work on the Phoenix site.
3. Sound MAX loud setting will NOT save after reboots. After boot, the sound is all the way up, loud. After talking with Phoenix tech, no fix. However, if FastBoot is on, the audio may save to a lower setting for about 24hours. If you don't use HU for 24 hours settings are lost again..
4. Screen will reflect windshield in GS Gen3 Lexus. May be an issue in sunlight.
5. If you wear Sunglasses or have glasses that do auto shade to dark, you may not like the screen because it can be hard to see.
6. Radio- Local / Distance not working. Can't find a fix. However Local radio is working fine. I get most local stations clear.
7. Temp display worked for 2 days now showing -40 at all times. (No fix).
8. Fast-Boot image changing. The stock app that changes the BOOT-Image will not work. It is out of date and will not work with Android 9+. It needs an update from Manufacture. A Phoenix Auto add-on app (download), also will not work, out of date. App complains of an Error with the Android version.
Add-On that work:
1. Musicolet from Play Store. The Stock Audio player sucks big time.
2. Bluedriver OBD2 reader.
3. Torque Lite or Pro OBD2 reader.
4. Function Generator, from Play Store.
That's about it.

Guidance for Android Head Unit

I currently have a Kenwood KVT614 head unit that I hate with a passion. I can't stand the useless screen (without apps it really serves no purpose), the navigation software and about everything.
As a result I am considering switching the head unit out and I love the idea of something running android.
My car is an electric car and it only has a single DIN slot, so I am somewhat constrained in my choices.
Ideally I am looking for an android head unit that covers the following:
- Can run android apps, e.g. navigation (both offline and online via the phone)
- Tethering - I read that some headunits have issues with Bluetooth tethering which is obviously much better for phone battery
- Having an electric car, I actually want the headunit to turn OFF (not sleep) when the car is off
- Screen size: not too big - probably 6-7 inches or I saw some "very wide" widescreens at 8.8 inches that would fit well
- I also like the idea of screen mirroring or android auto (and carplay) working but I would very much prefer for this to work via wireless (not some stupid cable)
- power consumption would ideally be as little as possible with this being in an electric car ...
Does anyone have any recommendations?
I have been looking at some of Joying units, since they seem to be the most modern android head units with 4GB RAM, 32 or 64GB storage and running Android 8.0 or 8.1 …
Would love to get some feedback.
And how do I determine whether a head unit is a MTCB or MTCD, or whatever?
Is there a database or list somewhere? Does this no longer apply to new headunits?
It's too bad there is no sticky or wiki with recommendations and some guides.
Once you know your board (MTCx) there is some decent info, but for someone looking for a single DIN headunit there current forum setup is pretty useless.
No one helps here much.
The new joying intel based units have a new dsp chip that will blow everything out of the water in android platforms. I ordered on last week. Will be doing a review on it by next weekend hopefully

CarPlay and Siri support in chinese android based head unit

Hi
I have an old (>5 years) android 4.4 chinese head unit
The main problem with the unit is the slow (~30 seconds or more) startup time, and the limited memory and slow cpu.
I am thinking of upgrading, and most manufacturers offer similar specs with newer Android versions.
Do any of these chinese units offer true Apple CarPlay and Google AndroidAuto support (preferably with wireless phone connection). that is, the ability to operate the apps and the units with voice (Siri / Google assistant) including reading and dictating messages, and making calls using the phone's dialer rather than a specific app?
Can anyone recommend a specific unit based on personal experience?
Android is open source, so it is up to the operator in question (in this case the head unit designer) to ensure proper operation. You don't really need AA on an android head unit anyway. Anything which AA can offer can be had directly on the head unit itself. Auto phone hotspots are also possible with android phones, so your head unit can connect to the internet easily.
Apple does not now, nor will it EVER officially support any of these Chinese head units. Apple has a strict set of regulations which must be followed by head unit manufacturers in order to gain official support (certain operations locked out while driving for example).
Soooo... in either case its kind of touch and go, but more so with Apple though since Apple unlike android, does not allow 3rd party tasker apps and such to change any internal phone settings, which makes things like auto hotspots quite difficult to do.
thanks
I have contacted a few Chinese head unit manufacturers and indeed their "CarPlay" solution does not support voice based / Siri control
I have found, however, a product (link) which provides full CarPlay operation, including Siri interface on generic Android based head units.
The box offers both wired and wireless interface to the iPhone, and uses an internal microphone for voice operation.
I have not tested the box myself, but I am considering purchasing it (relatively not pricey...)
I know there is a risk that future iOS upgrades will render this interface useless, but if it works for the meantime - it might be worth it if I can keep my current Android head unit
Has anyone tested this (or similar interface box)?
I don't have an iphone so I can't tell you for sure but I think there was something about the head unit not being able to get wifi while the system is in carplay mode. You should do a search on that anyway.
As I said, carplay/AA is touch and go with these head units because they are not officially supported.

Android Auto - use without a phone

Hi there. I have recently installed an aftermarket Android 11 screen in my car. I set up the unit with a 4G SIM card so it has its own isolated internet connection, as I want this entire unit to be self-sufficient and never have the need to connect a smartphone to it.
Is there a way to run Android Auto on this Android unit as a stand-alone app without having to connect a phone or external device to it?
(this seems like it should be a basic and common question, but I could not find an answer using Search)
TIA.
No one knows what the head unit is, out of the many unit types and manufacturers.
What have you identified as a possibility to solve your problem from reading the forum
There is not really a "brand" per-se, it's a somewhat generic aftermarket Android unit manufactured in China and distributed by DMP Car Design for a Mercedes W205 chassis. The device is "unlocked" and I can install almost anything.
As a network device, It identifies itself as: 'Bengal for arm64'
Specs:
12.3" Screen | Android 11 | 6GB LPDDR4 Ram | 128GB Storage | Qualcomm SnapDragon 662 (sm6115) 8-core kyro 260 64-bit CPU
I would think most of this has no bearing on the app having the ability to run stand-alone (except for the Android version).
Thanks!

For what reason you want to mess around with Android Auto?
This app is meant to connect a phone with an OEM head unit to mirror the screen of your phone to your head unit.
In fact:
Your new head unit is able to handle all the apps itself a lot better as any AA installation would do.
If you don´t have a phone connected, you won´t be able to make phone calls at least.
So I am really curious what you expect to get and the reason for your question.
Hi, did you resolve the problem with your android head unit because I've got the same predicament . Thanks

Since I have work accounts on my phone, I cannot connect to external devices. Additionally, I prefer not to have my car's system or devices be dependent upon an external device to function. From my perspective, the only requirement I should have to make everything in my car work is to have a key, that's it.
I like the clean UI of Android Auto and it works well for native Google navigation and music control in one simple interface which is why I was looking for an "easy" way to run Android Auto on my aftermarket Android car screen without having the dependency of a connection to a smartphone to function.

Hi there. I did not spend a lot of time pursuing this as I ended up going down too many rabbit holes in search of a solution.
I dropped trying to run Android Auto as a stand-alone app without a smartphone connection and went with FCC Car Launcher. In the end, I gained a huge amount of functionality and customization by using FCC. I now have a Google moving map, music controls, and much more on a single home screen without any dependency on a smartphone. (my headunit has its own 4G internet connection)

Using Fcc is surely the best solution.
As I said... Stand-alone Android Auto is not possible. you always need a Connection between phone and head unit. This is the way this app works...
I already use Fcc nearly since the start of development and I would not use anything else.
I have a 2016 RAV4 with Entune radio. Looking for a GPS Navigation capable unit. I have an Android phone. Seems like an Android OS wireless and wired head unit would work. Extensive research led me through Pioneer, Kenwood, Alpine, Sony: all poor values. Car stereo dealers want a fortune to install. I value function and reliability. Any suggestions on a plug-and-play easy install unit that will keep my steering controls and factory backup camera? T'eyes CC3 and Dasaita Max 10 both are on my short list. Prefer to buy from US only.

Head Unit Recommendation for Car Dash Board

I have a generic 9" Android Head Unit (K6_11_OH??) running Realdash app as a car dash board.
It works quite well using both of the USB ports for serial data (UART) and GPS input. Basically nothing else is required other than wifi to install head unit app
Main issue I have is the head unit re-assigns the USB COM ports each time it powers off and back on. This is annoying as I need to re-assign the dash app inputs every time I turn it of and back on.
Can anyone recommend a generic 9" head unit and chipset combo for the following: ??
- Easy to root
- Easy to customise ROM to strip unwanted apps and bloat
- Easy to customise Launcher / UI to remove (Dash app auto launches but not good if radio also tries to auto launch)
- USB ports enabled and easy to assign and access
- GPS
- Wifi
- 2GB RAM is sufficient
- No need for any other features that add cost such as high end music features (So relatively inexpensive)

There seems to be so many options, I don't want to make the same mistake and buy another one that is not well supported, which is why I asked here.
The one I have now has firmware with K6_11_OH and the last updates I could find was 28/06/2019 and it seems they we never very widely supported.
I had a head unit for my Mazda which is nice. I got it from Bestycar which has an SC7862 chipset which is great for normal music player but more advanced and does not seem as easy to customise and simplify like I want for the basic dashboard specific use for my project car.
So I assume one of the MTC units like a PX5 or PX6 chipset might be the best way to go now?
The dash has been built using a 9" unit this exact shape and I would rather keep this the same.

Don´t get your point...
You are searching for a good supported and quality head unit, right?
In this case you really should dive in at Joying for FYT units ( https://forum.xda-developers.com/f/fyt-android-head-units.12445/ ) or may be Klyde for CSN2/CSM4 units which are supported in this forum part.
At least you need to search for a unit specially for your car, or you need to search for a universal one with 2-DIN. Don´t ever buy a 1-DIN unit, as they all have severe issues with overheating if they are based on 6- or 8-core chipsets.
But by the way... the points you mentioned in your first posting... Sorry, but what do you expect to get?
I was expecting someone might say something like "UIS7862 head units seem to be the easiest to root hack and customise".
I don't actually want an expensive unit with heaps of great audio features as it is just a screen with 1 app and serial data feeds.
If I could get an Android tablet for 12V car use, with 2 x USB ports and completely raw Android ROM I'd be happy.
