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.

Comparation between 2 Eonon units

Hello mates,
I want to buy 2din android head unit for Mazda 6 GH 2009. Via Eonon website I can find 2 models almost similar and I don't know wich one is more powerfull, so the two options are :
1) Eonon GA9198B - PX5 1.5GHz Cortex A53 Octa-core 4GB DDR3
2) Eonon GA9298B - Rockchip PX30 1.5GH Cortex A35 Quad-Core 2GB 2GB RAM
I know is a huge difference between 2 and 4 GB ram but I don't know anything regarding those two cpus ... Any Ideea ?
Also will be much apreciated if you sugest other head unit better then those two mentioned.

Hey! I definitely recommend the PX5 over the PX30 - the PX5 is faster, more established and has lots of support on XDA. Have a look in the MTCD forum if you want to know more about these units.
I have an Eonon GA2171S which is PX5 and it is great, and there are lots of mods available. I definitely recommend installing Hal9k 3.1 ROM for full functionality.

Any reason not to go with a PX30 , I'm looking at the GA3175 as the price is good and specs seem pretty good.

I take it you mean the GA2175? See my previous post - PX5 is faster and has much better support here at XDA for mods etc. I'm not aware of any ROMs for PX30, while PX5 has Hal9K 3.1 which really fixes all the shortcomings of these types of units.

Yes GA2175, i saw your post and i'm not interested in rom availabilty as yet so thats no issue. Was wondering if i would be disappointed with it over a 2170/2170B, 2175 is currently $214 versus 2170B $274. Fitting kit for my canbus Landrover was $185 which has killed the budget a bit.

Ok fair enough, the PX30 will be a little slower, but in all there won't be a lot of difference. Screen and components will mostly be identical. Out of interest why are you getting a canbus fitting kit?
Couldn't you find a unit which fits your vehicle?

Oh ok, yeah the ones which are made to fit certain cars generally already have the canbus functionality so don't need a fitting kit. What model land rover is it? I can see some for a 2007-2012 Freelander 2 like this:

Joying Android 8.1 4/32Gb with Intel SC9853i or Dasaita Android 9 4/64Gb RK3399-PX6?

Looking to buy a new android head unit, after some research , most likely I would go for one of the 2 below:
Dasaita Android 9.0 Car Radio 2 Din GPS- 2018 PX6 Built-in DSP IPS Screen 4Gb+64Gb 6-Core RDS WIFI Bluetooth
Joying New 10.1" 1 Din TDA7851 Android 8.1 Car Radio Player Multimedia GPS Navigation Audio Stereo DSP
Dasaita is a 6 cores - 2 cores running at 1.8Ghz, 4 at 1.5 Ghz, the benchmarks shows this unit performing better on the single core test, Joying is winning the multi-core. Not sure how much of a difference is going to be in a real life normal usage. Both units should perform nice. Joying unit comes with the new 8 core Intel SC9853I with 1.8Ghz per core, from what I read on this forum, looks like this product doesn't feel as solid as the Dasaita unit, still things that are being fixed through monthly updates from the manufacturer. Joying has SPDIF Coaxial digital audio output, Dasaita has HDMI out for video as distinctive features for these two units. One big concern would be regarding the Joying unit that it might get hotter than the Dasaita unit plus the not so polished software. Not sure which one to go for, I would appreciate your take on this, if you own any of these 2 units. PX6 RK3399 or Intel Airmont SC9853i ?

Hi, as being switched from px5 to the joying intel sc9853i head unit, i would definetly choose the dasaita px6 for below reasons;
1- Cpu power does not means everything and intel cpu gets very very hot 80~100 C during summers, of course this could be avoided by adding extra fan along with a heat sink but small one hence there is not much space inside the cage
2-PX6 is most known platform and lots of flexibility cos its a well known product unlike the joying intel head unit
3- Software of the joying is terrible, there are a lot of bugs and those will be affecting your daily driving experience and they will make you crazy after a while believe me
4- There is a joying support only allegedly, most of the time they can not be able the solve the problem and that garbage intel head unit has a lots of way to go to become a normal daily usage head unit
5- SPDIF is not a game changer option by itself, i have done side by side rca-spdif outputs and there is a very tiny difference in terms of audio quality
6- There is no xposed framework support which is tremendous effect on head unit ( I am putting this as a standalone remark hence this could fix the some of the bugs)
I hope these are the answers which you looking for..
cheers..

The PX6 can also become very hot. Same issue with all the faster CPUs.
Another point is rooting/Xposed/custom roms: I'm sure that Malyask has a PX6 custom ready in the near future. He already made one for the PX30 (don't buy a PX30).
And HAL9K most probably will have a PX6 custom rom pretty soon as well as he is "sponsored" by some Australian vendor of those units.
Due to the new flashing technique used on the 9853i (compared to the Joying Sofia and PX5), it is now also possible to make a custom rom for the 9853i. (but as long as my PX5 is working properly I will not switch to a 9853i and maybe never).

I have same dilemma as you. I tried to list out pros and cons for each in my opinion.
Above all else, I just want it to sound really good.
Dasaita px6 dsp pros:
Android 9 vs 8.1
Rockchip platform seems to have more longevity / development vs intel ?
Mali 864 vs Mali 820 (not a huge deal)
Faster single core performance
HDMI out (nice to have)
2 camera inputs
3 1.5 amp usb outputs
Cons:
Need to purchase android auto / carplay dongles separately (100+ for both)
No spdif out
Screen not easily / quickly removable
Unsure if canbus adapter for chevy cruze is compatible
Joying 8.1 intel DSP pros:
spdif out
android auto / apple carplay support built in via zlink
Easy to remove screen
Seem to have good technical / customer support?
Joying makes a direct 7 inch oem style replacement for my 2011 silverado vehicle, which makes getting harness / canbus adapter easy....
Faster multi core performance from CPU
Cons:
No video out
Android 8.1
usb / bluetooth limitations?
overheating issues potentially (live in phoenix lol)

I personally still using the 3 years old PX3 from Joying.. had twice the screen replaced for free due to cabling fault
and by looking at some reviews for the new units and build quality, I'd say they are quite good. They even produce variants screens like the 8" one that looked pretty solid.
The only downside I may think of is only the Android/software support for the Intel units. You are pretty much only relying on 1 single seller/manufacturer for the updates, unlike MTCx units.

WOW! Also I'm in big dilema ...which HU i'll have to choose: joying, xtons, witson, eonon, daisata, so many brands .... I was determinated on Joying with Intel SC9853i, because at this moment they offer HU with best hardware specs on the market, but after I read this thread and this one I have big reservations.... For me and my car best fit is a HU with buttons, not only touch. I prefer this ones because they looks closer to the original media player.
So, after 1 week of searches, digging, I have to face it with this conclusions:
-Joying have best hw specs on market, 8Cores Intel SC9853i, built in DSP, responsive support, but many bugs;
-Xtorns have a good build quality on their HU, maybe the best, sadly NO built in DSP, more expensive than competition, they have 6Cores PX6 on their lastest HU, not so much info on this forum about xtrons and their rom stabiltiy or support;
-Witson, I'm witson old HU owner, quad core, 1GB ram, and the experience was average, because the lack of ram memory, but after 2 years it still working. Now they offer 8Cores Px5 with a fair price, NO DSP, also not much info about support
--about other brands I have no knowledge, so no opinion!
After this conclusion, now I'm aimed on Xtrons, but in no hurry! I think if they had DSP on their unit, it was a 1st choise for me...so I have to find more info about user experience with this brand. Maybe someone share his experience/opinions about xtrons , and why not, about anyother brands to complete this thread!
THX!!

Very hot is a relative subject. The question is does it become as hot as Intel and throttle? I think in the past also Intel units had more heat related issues than other units. But more importantly, you never know when Intel will stop supporting the platform. It is new and risky.
That said, Joying Intel units have 2s boot. I haven't seen any PX6 unit which claims to support this. I wonder why? as PX5 units had this feature???

Of course heat is relative. But the PX5 definitely got hot and started throttling down. Cooling it was one of the first things I had to do. I was not able to find the specs back, but the px6 iss comparable to the PX5.
Lots of home media units contain PX5s and cetainly need a big heatsink. Based on same spec measurements I guess it is the sam for the PX6 (but I can't prove, as I can't find back these measurements )
the 2seconds startup has nothing to do with the CPU, but with the additional hardware: the MCU and MCU firmware. Only the FYT based MCU types can do this.

@surfer63 it is interesting information about 2-3s boot. But why FYT does not have PX6 units? To be honest, right now I am not able to find any PX5 units with fast boot even.

I don't know whether they have or have not PX6 models. Joying only has the 9853i models from Fyt. There are however more FYT resellers than Joying.
Why do you want to have a PX6? You want a good functioning unit with as few bugs as possible. Performance wise it doesn't make a big difference, if any.

The downside for Intel socs is the precious trial with Intel Sofia units.
Manufacturers bet for Intel two-three years ago and moved fast again to rockchip platforms leaving Intel Sofia's with no support
In my opinion dont let be tempted by hardware specs...here the key is the software.
These units have hardware enough for the extrnse use for the car environment....if software is not stable....then your headunit is useless manufacturers don't give you the correct support (the most often case) then you have to move to any developer support....
Today the MTCD/MTCE based mcu units are the best developing supported (thanks to malaysk and hal9k) both are moving to px6 now.
With respect to which brand....in my opinion...many manufacturers claim warranties but no answer when troubles appear. I can recommend Dasaita (you can read many posts in which dasaita has been made the correct support for customers)

I followed Intel path for 2 important features that matters for me:
1. Fast boot. My unit is up less then 1 second and this aspect is very important.
2. DSP that gives a much better sound quality and settings compared with any PX solution I've tested.
And another big factor that made me decide was that HU i bought looks 100% like OEM unit including UI menu and is plug & play for all car features. Is not Joying brand but is based on same FYT solution. Now i am looking to find a way to root this device.

How bout the nee Belsee 9.0 units? How do they compare? They have a plug and play for the 9th gen accord. Cant find any info on Belsee

So is that fast boot a hardware thing or software based?

Both. It is done by the MCU hardware and MCU firmware from FYT. It is not in the android layer. That is only reacting on it.

Px units have a sleep mode and waking up from sleep is instantaneous.
During sleep just few mah are consumed.. so no worries on draining battery
Px u mints have also dsp...did you tried a px with dsp before to be compared with your fyt with dsp?

The non-FYT PX units have a sleep mode of 5 minutes to something like 2 hours. Within this time frame they wake up instantanious. After max. 2 hours (or so), they switch off completely and cold-boot again needing 25-45 seconds to get to live again.
The FYT-units, both Intel and PX units, have deep-sleep and a 2-4 seconds wake up (the extra 2-3 seconds due to the MCU). Also after 4-5 days this wake-up is still 2-4 seconds!! And it does not drain your battery. The current is so low that a normal car battery can at least last for 30+ days before reaching 50% load, necessary to be still able to start the car.
That is a huge difference between the FYT units and the non-FYT units.

That is not true.
Px units (like mtcd) have a unlimited time sleep mode.
Just when detects low voltage of battery they shut down.
I had my px5 5 days on sleep mode without issues and waking up instantaneously

That is really great to hear. Until now I was really under the impression that only the Joyings did that.
You mention the PX5 (mtcd). Was that also true for the PX3 (mtcb)? I have seen many videos/images where they showed in the Settings this "switch off after xx minutes" (or whatever it was exactly called).
For me that was the only reason to choose a Joying. Cadillac Mike did quite some reviews where he also discussed the mtcd units and the Joying. He specifically mentioned the quick-start of the Joying. Unfortunately he removed all non-Seicane videos from Youtube and now seems to be paid by Seicane (and changed to 5after12 as user name).
And as all mtcd units are compatible: does that mean that what you say is valid for all px5 units?

On my px5 still the Menu allows you to choose between some.time to shut down or auto sleep....if you choose auto sleep...it lasts for days prioritizing the battery of the car as now it has a voltage meter to achieve this

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

looking for thoughts on head unit

I have a long road trip that is instigating looking at replacing the headunit again. I was looking at the eonon GA9480A but the reviews say it's slow to respond, doesn't catch all the touches etc. and I'm guessing it's because its only a PX30 w/ 2gb of ram.
I found a Bosion PX6 w/ 4gb of ram on aliexpress but worried that it won't fix the problem or that the brand may be sub-par since I can't find a lot of reviews online. Anyone have experience? will the better CPU and more ram address the responsiveness issues brought up on the Eonon GA9480A reviews?
Thanks for the help

Dont bother with the Boison Px6. I got one and its going straight back. too many issues to list but long story short is it uses an STM32 MCU which doesnt work well.

Any chance there is a "gold standard" head unit currently for PX6?

Just look for one with MTCE MCU. I just ordered an insudar for £240 but lots buy Xtrons or Joying but they are a bit more expensive for the same thing.

Most of these HU has resolution of 1024 x 600. I searched for better resolution ones and found none in price range of ~£200 so gave up and bought a cheap PX6 unit. Even with my £25 unit with 1GB RAM on old toyota car, never had issues with touches, responsiveness and overall general functionality. You already have PX30 with a good support here in XDA so don't know what kind of improvements you're after.
