I am looking to replace my newsmy unit, I like it but there is no plans for 5.1.1 and I miss an actual volume knob. I also like the fact that the MTCB and MTCD have both Power antenna and AMP remote wires that are separate
Is it better to buy a MTCD unit or a MTCB unit? I have found a joying unit I like that from what I can tell I can get with MTCD HW and 5.1.1 or MTCB and 4.4.4
So I am looking for advice as the the better path, this is going in an older car I drive in the summer, so no OBD2 or SWC but I have an OBD1 BT device I would like to connect to it
I think you kind of answered your own question. If you want Android 5.1, then you should buy MTCD. MTCB is probably more mature, with MTCD you'll have quarks and functions the might not work right.
Yeah I am kind of leaning that way.. more work to make it fit around my bezel, but i will be happy with a volume knob once again..

Do not underestimate the importance of a mature android version.. As of now I got an MTCD GS where the 3g usb modem support is broken, the STW controls are broken and the bluetooth system/support for OBD adapters are broken..
At the moment I am just sitting around this forum for the golden day to come for some solution to arrive.. But the boot time is somewhat better. (mine is around 15sec)
which is why I asked the question.. the 2 units are both Joying, same look, one is MTCB with 4.4.4 but I can use the ROM from Malaysk for 5.1.1
Or get the MTCD, hoping things get fixed as you stated. or keep my Newsmy and figure out a Volume knob solution.
the 4.4.4 (MTCB) is about $20 less too
I can tell you I upgraded from MTCB to MTCD recently and did notice at least one big bug is fixed.
Running Waze, used to often cause the volume knob to stop working. That has never happened on the new MTCD unit.
I believe the bluetooth/audio design is better on the new MTCD units as well.
If there is not a big difference in price I would probably suggest going to the MTCD unit because they obviously have made some fixes and improvements.
if the difference is too great, or the lower cost is attractive enough get a MTCB. I had one for a year and was quite pleased with it, even with the quirks such as the volume knob to stop working when you use Waze sometimes, or the poor bluetooth mic quality issues on some units it was still worth it.
that helps.. Which MTCD Unit do you have?
Also how is the Radio Reception?
Ordered a joying UL135. It should be a MTCD unit

After the upgrade I have a JY-UL124.
The radio reception is about the same as the old version. It is a little weak compared to the stock radio but its not all that bad. Maybe reduces the range of reception 10% or so. A friend of mine who lives a little further out of town, has the same 124 as the old Android 4.4 model, and he solved it with a cheap antenna amplifier that is turned on/off automatically be the head unit using the built in antenna amp connection. He probably has better reception than I do now and I live much closer to town. The units have a pretty good radio receiver processor in them actually: http://html.alldatasheet.com/html-pdf/470939/STMICROELECTRONICS/TDA7705_10/1947/1/TDA7705_10.html My guess is they probably need to add just a little more amplification in their antenna circuit.
I've seen several people here say that the OBDLink SX OBD2 to USB cable is preferred for Android HU's. Unfortunately it is currently out of stock on Amazon and stock is shaky elsewhere (maybe discontinued?) and it appears there are newer models that support FORScan, which is mainly a Ford protocol. I have an 08 Toyota Land Cruiser 200 series. Supposedly it will work with Toyota, but OBDLink recommends the MX+ for Toyota, which is Bluetooth. I don't want Bluetooth cause it will interfere with other bluetooth connections to my HU.
So which is the best one to go with? Get an OBLink on eBay from a good seller? Other options? Thanks!
What head unit do you have?

EKIY T7. Generic FYT 7862 based HU.
I ended up ordering an OBDLink EX off Amazon. It supports ELM327 and FORScan. The latter seemed to imply is was specifically made for Ford/Mazda and a few other vehicles and might not be compatible with other brands, including my Toyota, but from what I can tell, it's a general all-around OBD2 reader just like any other, but with these added features (ELM327 and FORScan). It should work just as good, if not better than other units for my Android HU on Toyota Land Cruiser 200. Time will tell. Aloha!
Hey everyone! I am brand new to this forum and joined because I saw the most quality forum threads on the Joying head unit line of products here than any other forum I could find. I have a 2000 Chevrolet Corvette that I am hoping to install an 8" Joying Snapdragon radio in and could use some help gaining legitimate reviews and maybe some answers for questions I have regarding the Snapdragon and other Joying products. I'll number the talking points below for anyone willing to contribute and help me out. Thanks!
1) How is the Joying Snapdragon product that you have experience with, EXCLUDING all experiences pertaining to steering wheel controls? the C5 did not offer steering wheel controls, so I'm out of luck for that luxury.
2) How bright are the screens? Given the radio location in my car, glares when the roof is on is very unlikely, but a brighter screen is always better and would help if I chose to use the radio while the top is off and the sun can shine in almost directly onto it.
3) This is a very, very niche inquiry, but does anyone have a Joying snapdragon or android 10 head unit happen to also own an Xbox 1 or newer? If so, could you please tell me if you can download the Xbox app from the Google Store and install it on the radio? Furthermore, if this can be accomplished, can you please see if it is possible to Remote Play your Xbox on the Joying head unit via the Xbox app? The way I am thinking about it, doing this would require you to pair a wireless Xbox remote to the head unit via Bluetooth and then having the radio connected to WiFi (hotspot or sim-card, I suppose), OR it might work with a USB-wired remote connected to the radio via the USB port(?). I wouldn't be playing games while driving, but it would be something very cool to do at things like car meets or whatever. IF someone tries this, AND it works... how is it?
4) I see a lot of reviews in certain places here and there that say the Joying head units really don't offer any improvement over factory radios. Can someone please school me on this? A Best Buy employee told me once that almost all aftermarket radios (grant it, he was referring to Kenwoods, Alpines, etc.) will inherently improve the sound (either by volume or quality) over the factory radio because the aftermarket units "push" more power (in watts?) than factory units. I've replaced the factory Bose "twiddler" speakers in my car with aftermarket JBL speakers that can be found at Best Buy, so I'm hoping the Joying Snapdragon can make the most of them. Other than that, my car's sound system remains the same.
5) Does anyone happen to also have experience with these units and their communication/compatibility with the OBD2 adapter? Joying offers a deal to get their wireless OBD2 device, which I assume may be used on apps like Torque and such. Furthermore, does anyone think you could buy an OBD2-to-USB cable and run a wired connection to the radio for a faster, more responsive reading when using apps like Torque to view engine and ECU data?
Thank you to everyone who chimes in! I really appreciate it and I hope to hear from you all soon.

From reading the forums what learnings do you have regarding FYT based chinese origin head units so far?
Your post reads like solicitation - the information is here for you to read.

So, like I said, I'm new to this forum and, admittedly, I didn't look into the existence of any community guidelines that this post might violate, such as the solicitation you think my post reads as. If that's the case, I understand it if you choose to remove my post. I am probably wrong to assume that this forum is similar to car forums in that a user may post a thread whether to distribute or obtain information. For example, in the Corvette forums I use, I can post a thread about a new exhaust system I put on my car and list some things I liked and dislike about it to help future buyers, or I can ask a question about how other Corvette owners have enjoyed or disliked their experience with an aftermarket seat that I might be interested in. In either of those scenarios, I wouldn't be accused of solicitating because it's kind of the normal thing to do on a forum. So I don't potentially make the same mistake in the future, can you please tell me why my post "reads like solicitation," what the community guidelines (or whatever they are) that I may have violated, and what you mean by "the information is here for you to read?" For example, am I not allowed to post questions here?
However, I can't post a question like this on the Corvette forums because 99% of the boomers on there only buy "American, REAL QUALITY" aftermarket radios and never give android head units a chance. The other 1% seem to use the Joying 8.8" head unit because they want to retain the factory radio bezel. So, nobody over there is doing what I'm thinking of doing, so I'm coming to the only forum I found where users post information about the Joying unit.
But, to answer your question about what I've learned, I saw and read a thread started by @tRidiot under the "FYT Android Head Units" category that was titled "Do not buy a Joying Snapdragon unit - actually, Joying's customer service in general pretty well sucks." which can be found here: https://forum.xda-developers.com/t/...service-in-general-pretty-well-sucks.4419619/ .
By reading this thread, I learned that @tRidiot had a really sour experience with Joying's customer service and was thoroughly disappointed with the way the radio interfaced with the steering wheel control canbus system (or whatever its called). So, I learned to not have any high expectations for the Joying product line to interface well with steering wheel controls. I've also read Facebook posts about this issue being consistent in other user experiences. As stated in my original post, I'm not really concerned with steering wheel controls because my car doesn't have any.
I also read a thread by @lowridincrew, with no title, in the category "Android head-units," that talks about the snapdragon product line by joying and compares it to their previous models. What i learned there is that the hardware in the snapdragon products doesn't seem to be as competitive (or fast or as powerful, etc.) as their less expensive products. It seems like some of those who commented on that thread have purchased a Snapdragon product and, in first impressions, seem to be okay with it. There seems to be an appeal for the new UI and that older models most likely won't be given the updated UI.
I've also tried to reach out to a YouTuber, SaabUnleashed, as he has done several android head units including the Joying Snapdragon, but he has not responded.
SO, that is all the information I have learned by reading threads on this forum. I would still appreciate any and all contributions that pertain to answering the questions listed above, and if I need to take my questions elsewhere, please tell me where I need to take them. Thanks!

I can answer question #4 as I've dealt with high end Kenwoods, Pioneers etc. It does improve sound and the person that said it's not any improvement over factory radios are delusional. The android radios offer a crossover and wide band EQ's. That alone improves sound quality a ton. I have a 08 Lacrosse and I've went from Factory to Kenwood DMX7704S to a Joying 4GB - 64GB 7 inch head unit. The Joying had way more control over the Kenwood. Whoever got in my car thought I had a amplifier installed but it was just my Headunit. I was able to fine tune it nicely. The only issues would be when adding a amplifier, either use the factory cables to go back to RCA cables straight to the amp or a crossover. The RCAs tend to be 1v and under as my Kenwood had 4v which makes a huge difference.

1 I've had 3 of the last 4 joying units and if you're okay with tinkering a bit to get it to your liking it's a worthwhile purchase. With a few caveats, you can't use Google assistant to make voice calls and sometimes the radio app starts when you start the stereo
2 the screen is very bright. I used to use one in my BMW convertible and even in direct sunlight I could see the screen. There is also a screen protector for some joying units on Amazon and I believe one is anti glare
3 yes you can install the Xbox app but you'd have to download the apk. The play store won't allow you to.
4 changing the EQ might offer a better experience but don't expect a mind blowing difference
5 you can ONLY use the joying obd2 with joying head units if you want to go the bluetooth route. As far as wired usb Idk but I can't imagine it not working.
Got word from a manufacturer on Aliexpress about one of their units They said the far better Snapdragon 665 versions of HU would possibly come out around June
There's no reason to go with a slower Snapdragon 625 compared to the UIS7812 imo
#1 If you are looking at Joying snapdragon units I believe they are all button less, which not having swc is going to be a pain in the butt as you will have to click on the volume icon and slide the volume up or down, hard to do while driving. But other. Than that it's solid. People complain at the fact that the 625 is an older chipset but this is a head unit not a tablet porformance is more than enough for radio stuff. One other thing people don't look at is LTE bands, the snapdragon units support band 4 and 12 which are big in the T-Mobile network, but i will note my Joying headunit has a 4g issue so haven't been able to experience a fully connected drive currently still going through customer service to rectify this issue.
#2 The screen is bright I haven't had issues with not being able to see the screen content. That being said it glares a lot, my unit being mounted 100% vertically reduces the chances of having glare issues but i can see it being an issue on my Avalon where the screen has a slight angle facing the windshield. When I had a Joying unit in that one glare was impossible to combat making the screen useless around mid day.
#3 you can download any android app as on any android device but you will not be able to pair a controller. I tried pairing my Xbox series x controller for hours, couldn't get it to connect, it seams Joying changes something in the Bluetooth interface that voids being able to access the main Bluetooth settings. For me that would make this point useless. I haven't tested USB connection only Bluetooth.
#4 This can be true. There are a lot of generic android radios for under 100 bucks that use the cheapest audio chips to get a product out and sold. This gives you the Android experience but overlooks the audio experience. Joying on the other hand is fairly expensive for a Chinese company sourcing android radios. The reason for this is they implement higher end components to also improve audio quality, and although it is not on par with high end pioneer or Kenwood's it does compare to radios in it's price range. In most cases if your car has only 4 speakers meaning 1 on each door and no factory amplifier the Joying will improve your sound. If your car has a premium audio system from factory IE. JBL, Bose, mark Levinson ext where you have 8-12 speakers in your car and bypass that with this radio it will sound like crap. It would sound like crap with any radio as factory amplifiers have different impedance and crossovers to compensate for special speaker wiring that your radio won't have. Another thing is if you plan to install a sound system in your vehicle you are told to stay away from these units as they distort at low volumes not allowing you to maximize the audio. Also true of old Joying units, these new ones get pretty close to 3v out of RCA before distortion at around 75-80% volume. I tested them with my DM-RTA. Granted this is not 4v as standard by pioneer, Sony and other headunit manufacturer it should suffice and or can be improved by a 200$ line driver. At 700$ still cheaper than any large manufacturer radio with similar specs as in size and functions like wireless car play And android auto.
#5 This I don't know but would advice to ask and see if you are able to pair a Bluetooth model and phone at the same time.
Thanks everyone for chiming in! I know this is a very dated thread by this point, but I felt like I had a few things worth mentioning in case anyone comes looking for it.
Per Joying's customer service, the snapdragon product line (currently) ONLY allow pairing with JOYING-brand Bluetooth products (i.e. steering wheel controller, TPMS, or the OBDII device) and devices categorized as phones.
I think this is a bummer because, well, I feel like one of the biggest reasons to buy an android head unit over other devices is because of the open-source, "do what you want" liberty that isn't given by its competition. This also stinks because it means that a device like an Amazon Echo Auto cannot be used at all -- this device would allow hands-free navigation or music, etc., but it requires a Bluetooth or AUX connection, both of which Joying does not seem to afford for the snapdragon products
I am still going to wait to see how/if the Snapdragon product line is improved as was rumored. I'm also curious to see how Apple's announcement of iOS 16's new and improved Apple CarPlay will change on these devices.
I don't want to discount Joying as a consideration when selecting a head unit -- as of now, I think they are the only brand to offer an 8" all-screen option. I think I still want to go with an android head unit, but I may find myself switching to a different brand or even non-android based unit.
I think @surfer63 wrote about fyt units needing to install obdII before any other Bluetooth devices like cell phones. He has really taken the time to post great info about these units, it just takes a little time and more knowledge than I have to sift through the info and determine if it applies to your unit. I have the hengcheng pro S9.

You still don't appear to understand that there is no "joying" headunit. Your comments apply to a factory type sold by a seller called JOYING.
Without posting the details of the unit from Android system information including the MCU, the comments lack context which may mislead others.
Hi everyone,
After having two older units and hours of browsing here I would like to settle on a good FYT unit. My two specific requests for it would be a TDA7850 amp chip and a bright, preferably non-reflective screen. Resolution and color gamut are not that important. Any recommendations please? Thanks
You don't ask for CPU?
Better do some some further reading. TDA7850 can be better be replaced with a TDA7851 to reduce heat (overheating) of the unit.
Secondly: the TDA7851 is on longer available. If you want a likewise amp, you need to select a TDA7838 (NOT a 7833). The 7838 doesn't seem to have the same quality but as the 7851 is no longer available, you need to go for that one.
And if sound is important for you, you also need to look at the DSP like a Rohn BU32107, which is a default on 7862 and some other CPUs.
Screens: most are the same in the higher end units for every supplier.
Non-reflective: Forget it! If you want that, get some anti-glare film and put it on your screen.
Brands: If you did some reading, you have seen them in this forum.

Thank you for your opinion. I respectfully disagree about TDA7851. I had units with both these chips and there is a night and day difference in sound quality. I have an old but very good Harman Kardon audio system in my 2008 Mercedes and it shows the difference very clearly. If you have an average sound system, maybe you won't hear the difference. It would be nice to use a MOST box that goes from optical output to my amp (it's fiber optic) to bypass the built-in amp altogether, but the only one I heard of is a Russian one that is not available these days for obvious reasons.
I see about the screens, thanks. I read very different opinions about the anti-glare screen protectors... May I should just try one.
Thanks.

Vey well. I am not such an audio expert.
Never the less: Where do you still think to get a7850? There are still some manufacturers using a 7851, but most are switching to 7838.
There are still a few. Notably, Mekede on Aliexpress said they can put one in for me.

Hard to believe, but who knows.

Ask for assurance and then dispute when you find its not.
But as we've discussed here, there is so little difference, it's not worth it - add an external power amp.
Thanks. Can you clarify about the power amp? I do have my OEM Haramn Pardon amp that I use through the fiber optic decoder box. But the box is connected through RCA. My understanding is that means it still uses the unit's amp. If it doesn't, why is there such difference in audible sound quality with different amp chips? Or is it because of something else? DSP chip? Please tell me if you know. Thanks
Found on Reddit, it this the case?
"nearly every single aftermarket head unit sold today doesn't have true preamp outputs anymore. They take their speakers level outputs, run them through a voltage divider, and connect that output to the RCA terminals on the head unit. So the signal itself is IDENTICAL, just lower voltage"

Like mentioned above: I am not an audio expert (and certainly not an audiophile)
Anyway, one of the previous "hardware guys" here also mentioned quite some time ago that they simply convert the digital AMP output to analog like they did for older units without DSP, and when starting to use the DSPs, they simply convert/feed that analog output into the digital DSP and the make it again analog on the DSP-output for the output. Instead of using the digital AMP output into the DSP and then finally to analog.
Thanks. I guess I better investigate digital output options. From what I read, this is not straightforward either
I may try the Mekede myself. I like the flexablilty and wanna see if thats a real 2000x1200 screen lol. I was thinking of going Fiber at some one point with a AudioControl DSP or a Nakamichi DSP. But in the meantime, I was going to tap into the factory amp in the rear and snip the male plug and wire it into a AudioControl LC7i.
Hello,
I've been using a Mekede 500S in my Citroen C5 for about 1 1/2 years now.
All in all I am quite satisfied with the device, but 2 points upset me:
no RDS fine / local tuning
the microphone issue
I like that the Mekede is very fast, and needs only a few moment before start to work.
Now I bought a new car, a Lancia Voyager.
And of course I want to change the radio unit to a Android head unit.
Are there good alternatives to the UIS7862 units?
With which devices does the RDS and the hands-free function work in good quality?
Cheers
Andi

I'm pretty sure RDS works on my Mekede M500s. I use NavRadio+ instead of the default radio app so don't know if that makes a difference.
The mic issue is simply that the internal mic is unusable and the external mics supplied for free are also rubbish.A decent quality mic sorts this.
I'm using my cars OEM mic connected to the external mic on the M500s and the call quality is excellent.

I think the FYT 7862S is currently the best platform for Android Head Units.
You could try purchase a new fascia and wiring and swap your current head unit in to the new car. Though it would need to be a fascia designed for the M500s screen, but it's the most common screen on these units.

RDS is a multifunction set containing 12 functions.
What @andi_n is meaning is that RDS-AF (Alternate Frequency) doesn't function. This is already in these units since 2015 and it still has not been fixed. China doesn't use RDS-AF (and a number of other countries don't either) so I assume it is of 0 priority.
But this is also my nr. 1 annoyance.
Hello,
yes, I mean RDS-AF.
I also use NavRadio+, it is a great.
I use my car for business and traveling al lot in different European Countries and I love to listen Radio with news and traffic information.
It is very annoying to search every few kilometers the radio station.
I'll definitely buy a new head unit, I'll leave the old one in the Citroen C5.
That's why I'm asking about alternatives.
Have the non FYT based UIS 7862 units the same problems?
Cheers

That depends. There are a few that support RDS-AF. If you search through @KoTiX2 posts about NavRadio (also in the "Android Head unit" and "MTCD" forum), you see which units do have real RDS-AF.
At least the Topways do: See "New "NavRadio+" app for TopWay based units: T3 and T8Allwinner, TS9 (intel), TS10(UIS7862) and TS18(UIS8151)".
I myself have been really tempted to buy a Topways unit as I am a radio listener too.
Edit: My remark about Topways having correct functioning RDS-AF might not be entirely correct. I asked @KoTiX2 directly in his thread.
