Beginners guide to Android head units - Android Head-Units

Hey all, I've been messing around with android for ages, I've built a head unit using a Nexus 7 running Timurs kernel. That's become fairly outdated now and I've discovered that I can buy one of the head units running android which does everything the nexus did but better.
But I am so out of the loop with all the terminology and it seems that there isn't an obvious Go-To brand.
I was hoping this forum could answer some questions that I'm sure a lot of people are asking. So,
What does MTCB, MTCD and FYT stand for, a basic explanation of them and why would you pick one over the other?
What are the most popular / widely accepted / most supported brands / models from each group?
I'm personally after a ~ 9 inch device I can use as a dash for my aftermarket PCM (RealDash is the app I'll use) that also has standard headunit features. I'm looking at a Joying unit but I want to know what my options are.
Thanks heaps for any information
Hopefully this can be made into a thread for new people to get the lowdown and basics of Android based head units.

I have had an ATOTO head unit for over a year now and I have been very pleased with it. I recently got a newer model that I will be swapping it out with soon.
ATOTO has the best value for features and performance on the market today. Their products are primarily sold on Amazon, and they also sell direct at https://store.myatoto.com/ . There are several reviews on Amazon and you can Google ATOTO reviews and read some independent ones as well. Overall, they come highly recommended. They have great customer support, but since they are overseas it is by email only with a 24-48 hour turnaround for a response. You can also search for ATOTO in the forums here and there are several threads.
I hope this helps...

I saw a video for beginners the other day on Youtube
He seems to have lots of other good videos.
I'm also new, even though I've used Joying for a decade.
It seems they all use the same image or build off a common base, like all units use a PX5 or PX6 rom image. I wonder if they build it themselves or where is the origin?

Atoto makes their own Android based custom ROM and UI, the current units are based on Android 10. Unfortunately, there is no resource I have found here to root this latest version. But, you can certainly install another UI like Nova Launcher and such.
BTW, their latest models have a 1024x600 IPS display with 178 degree viewing angle.

Atoto does not use these px5 or px6 images?

Ok, px5 and px6 are actually processors.
Then I guess what my next question is, do they build off a common Android for head units branch?

As in, I dont't think they all are branching the git repo of Android, instead of branching from some head unit branch?

This really ought to be a Wiki article (except XDA axed that) or a sticky. There are many people here who know a ton about Android but aren't conversant with head units. Most of the posts on this subforum have to do with specific problems for specific functions on specific units in specific cars. Not a great way to get an oversight.
Let me flesh out what I mean (from my naive knowledge and subject to correction/expansion):
Head units are composed of:
Chassis
Single DIN
Double DIN
Others?
Motherboard
STM32F microcontroller (usually?)
Speaker amplifier
FM radio tuner
WiFi interface
Bluetooth interface
Resistive steering wheel controls interface (2)
Serial interface to external, optional CAN BUS (OBDII) box
Rear view camera interface
GPS interface
Standardized? rear panel connectors
"Core board" (a pluggable, modular Android system) Often named after the Rockchip processor used, PX4, PX5, PX6. Is this the only format? Are these modules used for anything besides head units?
LCD/OLED Display

(No, also some kind of ALLWINNER boards mainly acting with 8227L chipsets, Intel...) Are these modules used for anything besides head units? (not really, because they are just some sort of "reader" for the main board, the communication between the hardware and Android is completely different from any other Android device.)

See my comments inline in red..
That is not that easy with these units.
The most important thing here is, that thread starter do not use the search function, which leads to a lot of duplicated threads. There needs to be a clear instruction to use the search and how to figure out which sub-forum to ask in, means the thread starter needs to know the facts of his unit in front....
As we see in the MTC and this forum, we often have to ask about MCU and Chipset and that leads often in asking the mods for moving the threads into the right forum.
If you ask me: I have no real idea how to get that structured in a way that someone who has the knowledge is able to help without check backs for details.
If you have a look at this forum, you might find some dozen of threads regarding the same MCU/Chipset... really not ideal.

I have been watching this guy's videos as well, but can't helped getting the feeling he is being heavily sponsored by brands like Joying.
Also: I personally don't believe, that a octacore head-unit is necessarily. There a plenty of Quad-Core ARM A7 headunits out there, which are below €$£ 150 where as the octacore units are way more expensive.

So personally I opted for a € 150 unit, featuring a 720P IPS screen, 2GB of RAM and 32GB storage and Apple Carplay and Android Auto support. The last one seemly is called AA, although AA is also the road assistance in the United Kingdom....
Anyway most people will tell you not to buy a Quad-Core unit, but I did it nevertheless. These units are in a way quite similar like the Nexus 7, which has a Cortex A9 instead of Cortex A7. The last one being one of the most energy efficient chipsets.... isn't that important as well for a car?
The Nexus 7 had a 800x1280 screen, and 1GB of RAM and worked just fine. Until the storage got screwed up.... I still have mine, but it doesn't seem to do much anymore.
One thing to consider: when using mainly Android Auto or Apple Carplay, than in theory even a 1GB RAM unit would be fine. I believe he tested some of these as well.... they where quite impressive for the money. Also technology is way better, than a few years ago. Even though it seems there hasn't been much going on at the budget side...
But budget head-units below € 150 used to be way worse: a few years ago I couldn't even find a single unit for my car, below € 250. Now it starts at € 110 with a completely integrated frame. Of course I would suggest adding € 40 more and getting atleast the unit with 2GB of RAM.

This is your personal thing.
I don´t recommend to buy such a QuadCore thing, as it is lame as hell, does not support deep sleep, does not provide any support in case there is something wrong with the unit. This, I already wrote to you in another thread.
Please don´t recommend such a nonsense as there are top units available for around 200-250 Euro/USD. It is may be okayish for you, but the majority wants and needs something which does not need these stupid AA or this Carplay.
To use any head unit just as a monitor for Android Auto or Apple Carplay is just a bit hard to understand, as the units with at least a PX5 has more functionality as Android Auto or Carplay would ever be able to provide.
Buy this overpriced unit with a QuadCore and I would really hope that we don´t read that you buyed just BS.

Well it's your personal opinion as well.... it ain't facts.... and it isn't overpriced. The euro is just very weak on the moment, one euro is only $ 0,99 I saw last time.
Ah well have fun with your expensive Chinese Android head-unit, I bet they break as fast as the cheaper ones and there won't be any difference when using Android Auto. And please stop calling it AA, because it's confusing as in British English that's how they call the road assistance. How do you call Apple Carplay then? AC? That's your air conditioner
For € 300 I can buy a JVC: so why the heck spend this kind off money, on a Chinese Android head-unit?
Anyway Saab Unleashed also tested an cheap ARM A7 unit, and it's just fine. This being even a unit with 1GB RAM and only 16GB storage. Also no 720P screen. It really depends on your own usage, how the experience with such a unit is.
Not all Android applications need so much processing. And also I don't believe it's a fact that these units don't support deep sleep. Because there is still a lot of difference between ARM A7 Android head-units. A quick search on Google learns, that deep sleep is supported within the ARM A7 chipset.
And it's not like that Joying or any other brand, is in the league of a Chinese brand like Xiaomi. So yes I rather go for a cheaper Android head-unit, even though it comes with a slower but very energy efficient chipset. Energy efficiency is also very important.
Oh and all Chinese goods bought directly from China, don't provide the warranty you are used to for example in Europe. If I buy a JVC unit, for € 300 than I can be sure to have warranty for atleast 2 years. An Chinese Android head-unit, no matter which price only provides warranty as long as the AlliExpress buyer protection lasts!

This reinforces what I've been saying. This whole subforum is an inbred world only with difficulty accessible to a non-auto Android user (or even developer).
I presume from the above quote that those things are basically equivalent to Roku screen mirroring with some bells and whistles thrown in?

Well that's usually the case isn't it? But I just recently heard about Roku, saw those streaming sticks lying in a Germany Saturn. Didn't know what it was, but I guess it's something like Amazon Fire stick?
But actually the cheapest vehicle specific headunits, don't even come with Apple Carplay or Android auto support. I considered getting the cheapest one, as they are all able to use native Android apps.
Only I was concerned, that 1GB RAM would not be enough to atleast run Google Maps and Spotify on the same time. So I looked further, compared multiple sellers. Mostly all offering the same ****....
So I was surprised that Ekiy, was offering a unit that came with a 720P IPS screen. While other resellers, sell these kind of units with a 1024x600 TN Screen.

How to choose which unit?

I am looking to buy an android head unit. I've found a few with different specs and screen sizes. I am wondering if someone with some experience with these units can help.
I'm trying to choose between these 3 units.
http://www.ebay.com/itm/10-1-Quad-C...For-Toyota-Highlander-2011-2014-/181834823295
This one is 10 inches (good), runs android 4.4.4 (good), all the latest specs...but it says it only works on 2011-2014 toyota highlander models. I have a 2009. It doesnt make sense because all of the other ones are made for Highlanders from 2008-2013, which is the 2nd gen and this looks like it is an exact replacement for my head unit. Not sure I want to gamble on that, otherwise this would be my first option.
http://www.carjoying.com/quad-core-...ouch-screen-1024-600-resolution-double-d.html
This one is only 8 inches, but it gets good reviews from some users on the Toyota Highlander forum. IT has all of the latest specs, like the one above. And it is made for my model year.
http://www.ebay.com/itm/Pure-Androi...n-/181738329265?ssPageName=ADME:X:RTQ:US:1123
This one is 10 inches, but it has an older dual-core processor and is on android 4.4.2. It is also made for my model year.
There are so many options and they all look a little different. I dont know how to choose!!! I am mostly planning to use this for navigation, bluetooth audio/calling, and FM/AM radio. Of course, all of the android functionality is great, but those core functions are the most important for me. Anyone have any ideas?
I do not have a highlander, but have been doing days and days of research and cannot decide. I am on the market for a generic 7in double din unit. Hopefully some people who have lots of experience with these HUs can chime in to provide guidance/input.
I have been looking at joying, but they seem to only provide HUs with 1GB memory only. Is the 1GB memory enough? Most units these days have 2GB options.

Actually most of the units ARE 1GB units. Pretty much every single android head unit on the market uses the exact same small CPU/memory integrated sub-board that plugs into the main board on their unit. In fact the same motherboards are used between the dual and quad core, 8gb and 16gb flash models, only that small internal pluggable cpu board is different. It is also possible that these units will be able to be upgraded to faster CPU's with more ram in the future by swapping out the CPU boards.
All of the 2GB units right now appearing on the market, are usually a totally different design of having an entirely separate android pizza box(I am guessing they are repurposed TV boxes or something) which you have to figure out how to install somewhere and also a separate screen unit that you also have to install in the dash. The 1GB RAM head units are all a single integrated unit that installs in the regular double din location. I personally like the traditional single unit designs myself and chose not to use a 2GB unit because of that.
But really the choice comes down to price, specs (quad core, 16gb space, 1024x600 screen is what seems to be the best specs), and the features, button layout, if you want a DVD slot, or one without so you get a bigger screen, etc.. and then of course if you care about who you purchase it from and support etc..

Nixfu - thanks for the prompt response...this is very helpful information! What about the screens? Are they also similar across the board? I do not mind paying more money for a reliable/stable unit...I am more concerned about the risk of purchasing a HU plagued with software/hardware issues. One of the things I would like is having the ability to configure the HU to go into suspend when the power is switched off. I have seen several units that can be configured up to 2 hours suspend, but would like to be able to increase that up to potentially 24/48 hours or maybe more. You may have talked me into purchasing a CarJoying HU with your post/review of it Can that unit be configured to go into suspend longer than 2 hours when car ignition is switched off? Thanks again!

No. I think they all have a min of 30secs and max of 2hours in the settings menu. Maybe that is something that Malaysk could add in his custom firmware.

Newest android head units

Hi guys!
I am looking for a nice android based radio to my Outlander 2011. I found at least 5 types of design "Fascia change" devices. I think that they are not so popular among people so I have another question. I am looking for 2DIN newest device. Could you please give me a list of 5 newest or best pieces I should consider? It is very important for me to keep steering wheel buttons working and need very good sound quality on built in Rockford Fosgate audio system with external amp and 2-3ohm 8x speakers + woofer. I've heard that some devices not work properly or give not exciting experience.
Thanks a lot!

If you looking for a Android aftermarket there is no way you can choose with audio like the way you wanted. They're just simply like China Android phone or tablet placed on your car.

Personally, I'm waiting for the 8 core systems to mature a bit. I have a 4 core, and it's a little sluggish. I find myself having to roll back to 4.4.4 after upgrading to 5.1. Just too slow. The new 8 core systems are out, but it still seems early to make a firm decision. Ownice and Indashnet seem to be the 2 main manufacturers that I've seen. Everyone else does 4 core. Joying has a 2GB Intel based system that kind of rests in the middle, but considering it costs about the same as an octacore, I would rather wait a bit to see which of those the community takes to the most.
I got deeper into those 8 core and they seem to be super crappy as they use extremely slow Allwinner and Mediatek A53 which sucks. Intel in Joying looks interesting but this device has problems with obdii and few other things. I ve seen pumpkin doing also intel device. However maybe some of you know if there is any manufacturer who still has dvd slot with Intel SoFIA and 2GB + USB for pendrive music? Or at least USB.
On the other hand - is it very hard to make car USB in armrest working with such android device?

Or on the other hand - What about Windows CE 6.0 devices - are they causing less problems? What I need is nice and smooth infotainment system, working steering wheel buttons, bluetooth and usb and fast boot after turning engine on.

Right now I believe the 2GB Intel Sofia head units with Android 5.1.1 from Joying are the best. There are 8 core units on the way, but who knows if that's one month or six months down the road... There are also some units advertising Android 6, but reports seem to indicate that these are a mess of a mashup between 4.4, 5.1 and 6.0, and not true 6.0 units. As for performance, I'm pretty happy with the Intel unit. I wouldn't use it for gaming, but it does all what I need it to do which is Maps, Spotify, 1080p movies and so forth. Unless you have some specific need for doing something that requires very high performance, it is quite adequate as a head unit in a car.
As for special sound setups, it gives you preamp outputs, 4 channels (FR/FL and RR/RL) as well as a sub output. The sub output isn't really managed though, so no crossover or phase selection on it. You can use these preamp outputs to hook up aftermarket amplifiers, but don't expect the head unit to power big speakers with the internal amplifier.
I didn't read the same things about the 8 core units on here. Many people are saying that the CPUs are a lot faster than the Intel cpus, and at least some of them are running true 6.0, not a mashup. It's legit, but nothing has been rooted and the community is still divided. I've definitely read that the Intel CPUs won't be upgrading past 5.1 because they're no longer supported by the manufacturer as well.
My source is mostly this post, and the thread it's in:
https://forum.xda-developers.com/showpost.php?p=70311462&postcount=12
As far as I know, yes Intel has dropped the Atoms, but Rockchip has taken over the chips and will continue making them and supporting them as per a cooperation agreement with Intel (source: https://en.wikipedia.org/wiki/Rockchip look at the bottom to see Intel Sofia 3G). Intel may have pulled out, but the architecture isn't dead yet. Sure, it may be dying and might not have any new direct successors, but I recon it's time to upgrade the entire head unit long before it reaches the end of its useful lifespan (2-3 years). This will be true for any smart android head unit you buy today anyway..
Do any of the other 2GB RAM Android Head Units available today have a true sleep or suspend (ultra low power mode) that allows the unit to start up instantly like the 2GB Intel Sofia models? To clarify, this instant on feature is not the same as the past Rockchip or other cpu type of Android head units that have options for delayed shutdown of up to two hours or more. This new feature means you do not have to wait 30 to 60 seconds for the system to fully boot after sitting for a few hours or days. IMHO, the instant on feature combined with 2GBs of RAM appears to be the best or one of the best options for Android head units available today. Do the latest Ownice or Indashnet units have this instant on feature? If not, that would be a deal breaker for me, as I have Joying and Hotaudio units that work fine for most part (thanks to the xda firmware developers and contributors here). Nonetheless, these older 1GB RAM Rockchip units could be faster and the boot time is not acceptable in a vehicle.
Moreover, any Android head unit that does not allow for root access would be a complete deal breaker here, no matter how fast... (no root = no purchase). The one thing that concerns me with the 2GB Intel Sofia models is that nobody on xda appears to have found a way to access Recovery yet.
In regard to audio quality, even the 1GB RK3188 JY and HA units sound decent in my Mitsubishi with the correct factory amp adapter wiring kit and the Viper V4A audio mod app.. Please note that I'm not an audiophile by any means, so your mileage will vary.
Anyway, just my 2 cents... and thanks in advance to anyone that can let me know if any of the other Android head units have the instant on feature.
Happy New Year!

I recently installed a Joying 2GB RAM intel head unit, and although it is NOT a high powered cpu ( 4cores at 1.1 Ghz) it does seem adequate for its purpose.
Typically I run torque / bluetooth ODBII, dashcam/dvr, music app, tablet talk, read it to me, and google maps at all times. Processor usage is normally in the 50-65% range and it still seems quite snappy. The intel chip does run hot, and thermal throttling can be a issue. I added a big heatsink and fan at the top of the case, problem solved. The instant on works very well. When starting the car it automatically finds my phone, ODBII adapter, and hotspot within a couple of seconds of power on.
It does suck not having any type of recovery such as TWRP. The only way to recover from a non-booting system is a full reload of the stock ROM. It does leave the /data partition so at least all your apps are still there, and most settings can be restored using titanium backup. Just today I updated the boot animation with one I created and it wouldn't boot. It took me about 1 hour to get it restored back. At least it does have root out of the box.
The Joying is my first android based HU, and I'm actually quite impressed with it so far.

I guess my issue here is that I, also, already have a 1gb 4 core unit. So, for me, I'm looking for a bit of a better upgrade if I'm going to spend another $400 so soon. I am, honestly, hoping for a way to upgrade my current system - I don't think they'll make compatible modules for the Intel or the octa core. That said, I'm going to limp along with my current system as long as I can before making a decision. I think that for those making a decision right this minute, there's a lot to take into consideration. I would seriously recommend avoiding the 1gb RK3066 or RK3188 units at this point, though.
If you have a head unit that works today and you're not in immediate need of a new one today, then you can safely wait and see what the coming months will bring. It seems that the market for these Android units are finally moving away from 1GB ram units, in favor of 2GB ram. At this point, you should avoid everything which only comes with 1GB ram. I never had one, but from what I read they didn't allow much in terms of multitasking. The 2GB units will always perform better than the 1GB units, so the choice is fairly easy there. The benefit from the Joying Intel units, is that they are the only ones I've seen so far which offer 32GB internal storage. I don't understand why in 2016, now 2017 the other manufacturers insist on sticking with 16GB internal storage, but this gives a quite distinctive advantage to Joying. Also the previously mentioned sleep mode where you get true instant on feature is really nice.
Can someone having Rockford in Mitsubishi can tell anything about built in car BT and phone buttons in steering wheel? They still work or at least are used to control phone functions in HU?
What about USB in arnrest and AUX - do they work or is it possible to wire them for working?
Rockford will still have it's power? HU amp is written to have 4x50W while whole system is 8 speakers + 1 woofer altogether 710W. What is rockford's input?

The 32GB doesn't matter as much to me because I don't install that many apps. I have a 128gb USB stick connected for my music, and I can easily jump that much higher if I need to. 2gb ram is definitely important. The faster the CPU the better, though. My quad core 3188 is sluggish even when I don't have anything loaded and I'm not maxing the RAM.
A mate installed a yum cha Joying JY-135 and it seems ok. Radio signal seems to be weak. It seems to auto connect via bt to a Samsung 6 and starts to play audio but I have to manually press play to start audio on my M9. The screen doesn't dim when you turn the lights on which kind of sucks.
I think for music it should be fine and works well in my mates Nissan. As for me, I'd be using the rca's, just a shame that there's no sub volume control so you'll need a separate sub control knob.

Mates car is a Nissan X-Trail '07. I've got a Subaru Liberty Gen 4. We'll connect it with the proper supplied loom soon, only temp spliced at the moment. Can confirm that hu turns on straight away.
Almost made decision but still need to get sure. There are 2 options with Intel Sofia: pumpkin and joying (2DIN standart) Which one better to choose and why?

Can someone having Rockford in Mitsubishi can tell anything about built in car BT and phone buttons in steering wheel? They still work or at least are used to control phone functions in HU?
What about USB in arnrest and AUX - do they work or is it possible to wire them for working?
Rockford will still have it's power? HU amp is written to have 4x50W while whole system is 8 speakers + 1 woofer altogether 710W. What is rockford's input?

Hi, i have just installed a Joying UL-135N2 in my 2011 Outlander Rockford Navi.
Some part of the installation where quite manageable, but some parts are more complicated.
With the right adaptor, CTSMT002.2 from connects2 the Rockford and the SWC works.
The original BT will not work, but the SWC works with the HU BT functions.
Reverse camera needs 6.8V signal from the HU, so here you need an step-down converter and some soldering.
The USB in the armrest needs an adaptor cable, alternatively you can disassemble the mid console and solder the cable.
I have ordered the step-down and the adaptor cable , but not received yet. I have tested the camera with 6V, but the image quality is poor, hope the 6.8V is better.
Out2011

Comparing a few different models, not sure what to get? Need some advice.

Edit: Narrowed down my list to three models. Goal here is to get the best bang for my buck and would like something with decent XDA/aftermarket support and manufacturer support in the event I have any problems. Also needing DVD, solid bluetooth for TorquePro(must be reliable, my vehicle requires constant measurement of various temperatures), USB/SD, solid FM, decent sound, decent offline GPS, and overall reliability. Ability to use 3g/4g would be nice but purely optional. Faster boot would be nice as well.
Pumpkin 6.2" Android 6.0 32gb ROM 2gb RAM TDA7560 OctaCore FastBoot DVD- Model #CN10-02207B I can't seem to figure out exactly what CPU is in this one. It has the TDA7560 audio, plays DVDs, has front aux/usb/sd which makes using those ports much more convenient. Downside is it has physical buttons down the left side. Not a huge deal, and it seems to hit on all my other requirements so I could look past that. No idea on aftermarket/XDA support.
Xtrons 6.95" Android 7.1 2GB/16GB RK-PX3 64bit 4core DVD - Model #TA695P Can't figure out what audio chip/amp this one has and it's only a quad core so 'fast boot' isn't available. It is also the PX3 which, to my understanding, means it has better root/rom support on XDA? No idea on Xtrons support.
Xtrons 6.95" Android 6.0 2GB/32GB OctaCore FastBoot TDA7851 DVD - Model #TB697P Can't figure out what CPU this one has. Pretty much same requirements met as the Pumpkin, but face looks cleaner without those physical buttons. Has the better audio amp chip. No idea on aftermarket/XDA support or how Xtrons support is. So far this one is my favorite based on appearance and specs. Main downside so far is that USB/SD appear to be on the back of the unit or via cable plugged in to the back, so this hurts convenience a bit.
Anyone?
Recommendations on a better brand/model would be nice too. Need to get something ordered today.
Also looking at US-JY-UM128N2D which apparently has an internal amp, and US-JY-UM124N2 which does not. Also found the Xtrons TA695P which is apparently an MTCB head unit and has better root/rom support?
For some reason I can't seem to find much info about any of these models and I would really like to get something ordered today. Looking for reliability and ability to easily root/rom if possible. Sucks not having a radio in my truck right now and after looking at these android head units I'm more confused now than I was before due to so many different models and variations of model numbers and etc.
I also need to know if I can use my google account to access my apps/etc in play store, or if I'm stuck using a their pre-added account?

Get a Joying.
I would avoid 124 or 135 because the touchscreen is inset by over half an inch under a deep plastic bezel that makes touches near the edge challenging, and drag-in-from-outside gestures impossible.
Look at either UM128N2 or UM128N2D.
There is open source work being done on Joying intel units, so you can expect some much greater stability and choice in software for them.
HOWEVER, there has been no work done yet to address the digital amplifiers (the one with the "D" on the end), so you probably wouldn't get any sound on that one just yet. BUT, its not the most complicated hardware to deal with. The main dev doesn't have a "D" unit.
Whatever you do, avoid UM128N2PX5R, which has a new extra crappy CPU. They might be tempting, because they are CHEAPER than the Intel N2.
Could you elaborate on not getting sound with the UM128N2D?
And how is the UM128N2D in terms of bluetooth? It is extremely important to have TorquePro working reliably on my truck since monitoring temperatures can save the engine(powerstroke).
This is my list currently...
Pumpkin 6.2" Android 6.0 32gb ROM 2gb RAM TDA7560 OctaCore DVD- Model #CN10-02207B
Joying 7" Android 6.0 2GB/32GB Intel SoFIA 3GR 4core w/ Internal Amp NO DVD- Model #US-JY-UM128N2D

Xtrons 6.95" Android 6.0 2GB/32GB OctaCore FastBoot TDA7851 DVD - Model #TB697P
BT on Joyings are basically OK (I have "D" model), Torque also works. I use my only Google account also on HU bying apps from Play market.
I've narrowed my list down to three models.

Rolled the dice on the Pumpkin 6.2" Android 6.0 32gb ROM 2gb RAM TDA7560 OctaCore FastBoot DVD- Model #CN10-02207B since it and other Pumpkin models seem to have better reviews all around compared to the various Xtron octacore models.

Newbie needs advice :)

Hi all,
I'm totally new here and have no experience with android HU's at all!
I recently bought a Skoda Octavia (2012) with a RNS315 in it. It seems the navigation updates are quiet expensive and the navigation itself is not that good I think. So I started looking for an other device.
I would love to keep basic functions as: PDC, airco, maxidot, steer wheel controls,...
My eyes felt on the Joying android HU's, especially the ones with the look as the VM130N2. This device still have some buttons on it, which is handy in the car I think.
This model exist in the Intel Atom X3 version and the Rockchip PX5. Is the last one the better choice? (newest version I guess)
Or are there other brands that are better for (almost) the same price?
I've read the Joying HU can use some extra cooling, but installing a fan isn't that big problem I think.
Does these units display the name of the radio station on the screen? Or only the frequency?
Thanks in advance!
By trading your RNS for Joying you'll surely get better navigation, but you are going to miss:
- sound quality
- radio reception quality
- Maxidot integration (no navi guidance at all)
- overall quality/integrity
But again the whole Android world will be at your disposal. I traded my RNS510 for Joying and did not have a temptation to get it back despite all Joying's flaws.
Other brands that are better for sound quality? (Pumpkin, Eonon,...)
The Joying HU are on Android 6 others are on Android 8, isn't it a shame to buy an older system now? Or no problem at all to update to the newest Android software?

If you buy a Sony you definitely have better sound quality.
If you buy a Joying, buy the one without the internal amplifier, for example the VM130N2 you mention and NOT the VM130N2D. You better use an external amp to improve the sound.
I have a Joying VM130N2 and would buy either a Joying or Dasaita back.
Atom X3 (Sofia 3GR) is slightly faster than PX5, but the PX5 is 8-core. In the case of multi-threading apps (actually only Google apps), more cores might be useful on a "loaded" system. Even though the PX5 is an underperforming CPU and not better than an Atom X3, it still is the future for the coming 1-2 years as every supplier is abandoning the PX3 and Sofia 3GR, and switching to PX5.
If you want to run custom ROMs, you better choose a Joying or Witson Sofia 3GR (gtx made a very good custom rom) or a PX5 mtcd to be able to use the Malaysk custom ROM. The Joying PX5s are non-mtcd units and therefore incompatible with the Malaysk ROM.
And w.r.t. Android 8: Choose very carefully. Some units are really running 6 or 7 and only have the look & feel of Android 8.
What do you think about the Dasaita HA2137-V840? Should have a better internal amp (don't know if it's true, or just publicity). Have had external amps in my car before, but don't want it in my "new" car.
Probably the dasaita isn't a PX5 mtcd?

My $0.02. Skip the Chinese head units. I've been through 5 of them in the last 10 years. First was a single din media player. It died after 3 years. Second was an ebay purchase of a Windows CE with IGO in 2011ish. Seller said it had GPS--it didn't. Then the screen died sitting on the shelf when I tried firing it up a few years later. Next I bought a Windows CE with GPS unit lasted 3 years till till DVD player died in 2015. Then the res of the unit/screen died on the shelf after trying it a few years later. Then in 2015, I got an android allwinner A13 single core 4.04/8gb storage/1gb ram. The unit died after 2 years. Plus it was so slow and under-powered, that it was a waste of time to use. Then I bought a Joying intel sofia unit in 2017 January. It was pretty good unit until it stopped working. The screen started flaking out intermittently on and off after 9 months. Joying admitted they had a fault but that they fixed it the manufacturing process but the solder joints needed repair from too many heating/cooling cycles.
I'm done with this generic Chinese junk. These units simply are not weather resistant for long term exposure to the elements in the car, and they lack decent cooling. All of this is aside from various complaints of buggy software implementations.
So I bought a Pioneer unit head unit with Android auto, and so far quite happy with it.

Look at the AMP chip. In the Joyings it is a TDA7388. Some other brand units come with a TDA7850 chip and sometimes with a Pioneer PA2030A.
Those are much better.
The Dasaita HA2137-V840 does have the TDA7850 and a better radio chip than the joyings (that is also why I mentioned that I might buy a Dasaita back. All chinese units are definitely not top-quality, but the Dasaita is slighly better).
I have really no idea whether it is an MTCD unit. Please ask Dasaita directly via mail, either via AlieExpress of via their own site www.hot-audio.com

Yeah, well. My brother bought a pioneer Android unit (can't remember which one). He had to wait 1½ year before they fixed the bluetooth issues.
So much for Pioneer. It is a mixed bag everywhere until you buy a unit of at least 750 euros/dollars.

I second that. Chinese Android head units may be a suitable upgrade for older cars but are no match for recent OEM units. And most recent OEMs include Android Auto/CarPlay support which renders manufacturer navi useless.
In your particular case, the RNS315 doesn't seem to have that but there seems to be a direct replacement, the RCD 330 Plus, that keeps all previous functionality and adds AA/CP connectivity.

Android Auto compatibile HU recommendation.

Hello everyone.
My 3 years old 7" Joying Sofia 2gb HU died, and I'm looking for a replacement.
Since the release of my unit, I noticed that the new models are based on PX5, PX6 and the latest AIRMONT Intel units.
The most important things for me:
- fast performance and stability, which means at least 2gb of memory, preferably 4gb.
- good ANDROID AUTO compatibility, either natively, or good support for the app "Android headunit reloaded" which I've been using all the time on my dead joying unit
-Fast wake up time after sleep, I really don't want to wait a minute for having a working unit once I turn on the car.
Any alternatives to Joying Headunits? I was disappointed with the quality control of their units and support.
Any advice will be highly appreciated!!
Hi,
I never give "buying advice" as I only know Joying and can't compare with others: there is no clear pro/con here. Some users prefer one brand, others another. 9 out of 10 only know "their own" brand and promote that one (something like: the more in one community, the more community support you might expect?). But you PMed me with the question about advice so I will give my 2 cents.
From what I have heard Dasaita (Hot Audio) seems qualitatively a bit better, but that's from hear-say. They are also slightly more expensive than the Joyings.
I now received the SC9853i unit from Joying for only 63 euros for testing purposes.
If I did not have that new Joying one, I might "try" a Dasaita.
Build quality: All Chinese models range from "moderate" to "bad" quality. There is a reason why they are 2x-3x cheaper. I do not think Joying is worse than the rest. I even think they are better than a lot of the unbranded models, who are indeed even cheaper. And again: From what I have heard is Dasaita better and therefore also more expensive.
W.r.t. support from Joying: They do support you. Sometimes it is very good, sometimes it is bad especially when they do not know it or do not have a solution. Then they "wriggle" without giving a firm statement.
But they do support you. When reading about all kind of other, especially the non-branded units, there is simply no support at all and they only speak Chinese.
Concluding: my choice would again be a Joying, or a Daisata.
But again: that is only theoretically as I have never done an in-depth study of multiple models.
Edit: Dasaita is MTC-D/E and therefore supported by the HAL9K and Malaysk custom ROMs, if that is what you want.

Thank you for the very informative reply! I'm sure other forum members will learn from it.
I'm actually a bit disappointed with Joying, the device has never left the car, and suddenly the screen stooped working intermittently. After reading a but about this issue, it appears that the intel Sofia units had some poor soldering of parts on the motherboard, and after contacting their support team, they recognized the problem and sent me a link to a video on YT showing that I can fix it by soldering a part on the motherboard. Unfortunately trying to do so left me with a totally non-functioning device.
The only thing that Joying offered was a 5% discount on a new unit, and I felt really uncomfortable to buy a new unit only after 3 units, when it was clearly a bad quality control issue.
For this, I will surely look into that other DASAITA units. From checking their latest models, they seem to be cased on PX6, while the newer Joying have the newer Airmont CPUs.
1) Do you think there will be much difference in terms of performance between PX6 and Airmont architecture? They both have 4GB of RAM.
2) Any idea if the DASAITA have the quick wake up from sleep as the joying units? This is an extremely useful feature, as you don't have to wait until the unit becomes usable.
3) Apart from the ability of installing custom ROMs, what is the advantage of having MTCx units?
4) Is the ZLINK solution provided in these units a good solution for having Android Auto? I've been using Android Headunit Reloaded and it has been really good.
5) Is the new built-in DSP available only in the latest Joying models?
Thanks again

1. I don't think so. With 4GB everything runs smoothly and nothing is is taking those CPUs to the max as long as you do not play heavy games.
2. As far as I know (almost?) all newer MTCD/E models do also support quick wake up.
3. 10x more users (at least). 10X more knowledge (I think). All are compatible: per CPU-type/MCU type that is, so every PX6/MTCD is compatible with any other PX6/MTCD.
Look one level higher https://forum.xda-developers.com/android-auto/
And then check the MTCD forums. Read a bit more about them. They wil know about the quick startup.
Eventually I bought a unit from a local store, instead of dealing with shipping, customs etc...
It is made fekn FOXWAY, It has a PX6 RK3399 with 4gb of ram. I attached the settings page.
It doesn't have all day quick wake up, I can set it up to 2 hours, but after that it has to boot up. Although it's fast, I prefer for it to set it all the time as in joying units.
Also, I can't find a way to disable the touch or button beep sound, which is driving me.
Any ideas will be welcome.. View attachment 4927037
