I'm using a 4g card in Australia. It works but every so often it doesn't register there's a sim card there and have to reset the unit by putting a pin in the button on the screen.

I will be getting a 4g dongle and running it over wifi instead
[Android Head-Units] Kalergie:
Thank you for this thread. This is a great discussion.

I was wondering one thing. When looking at the different products on the Joying website with the Intel hardware, not all mention specifically that they have a SPdif/digital coaxial output but most (if not all) have the the green coax out plug in the picture. Is there any sure way to determine which headunit has the digital coaxial output?

Thanks a lot. :good:
[Android Head-Units] Kalergie:
Joying just answered my question. "Now all the Intel 9853i Android 8.1.0 head unit built-in DSP, support SPDIF Digital audio output."

I will be ordering one shortly. I mentioned to Candy to thank K&S Diesel for his great review! :good:
[Android Head-Units] DustoMan:
I got my JY-UO138N4G installed last night. The only issue I've run into has to do with Android Auto. If there's a navigation banner that shows up at the top of the screen, the audio ducks down but never resumes to the previous volume. If I close the XLink app while the audio is still lowered it goes back up to where it was. Also, does the default time/temp widget only show Celcius? I have my temp set to Fahrenheit in the device settings but that widget never changes.

Anyone tried the external mic?

Mine is not working, I have tried 2 different one already
[Android Head-Units] bitshifted:
Does anyone know if the DSP on these units can be bypassed or defeated?
[Android Head-Units] DylanHarper:
The popping is caused by the head unit, when it first powers on its switches on the amp / DSP, then when it boots up fully there is a sudden inrush of current.

You need to use a delay, to eliminate this or find another remote on source such as a switched fuse.

I'm having the same issue,

Hello, i readed this thread and i Think i'll buy a joying 10" to replace my pioneer f77. But can You confirm me that you control the volume with the joying unit. I have already a dsp. (waveflex dsp).

Paille, are You living in France ? Where ?

Thanks
[Android Head-Units] julien_blanche:
If you have universal canbus adapter then yes you can control it from wheel but before you buy i strongly suggest to have a look below thread for pros and cons;

Thanks for answer. But my question was not for the steering wheel ! My question was about the volume if i connect my dsp by spdif and not rca.

I ask this, because all the extern dsp have a separtly command for the volume. And i'm surprised that joying unit can command the spdif output. (i Will be happy if that Will be rigth).

Thanks for the link. I have some page to read lol !!
[Android Head-Units] julien_blanche:
Yes you can control the volume from the joying with external dsp connected. I have tested this head unit ay home extensively and sq is great but i can not say the same thing for hardware quality and software.

Hope it helps..

Does google assistant calling work natively with this unit?
[Android Head-Units] davemazo:
Google assistant

Not for me it doesn't. I've tried and tried. I've followed all the advice and tips on here but all I get in reply from Google Assistant is "I can't make calls yet". Nor does it send text messages. Works perfectly on my Note 8 when it's not connected to the Joying
[Android Head-Units] Crimson Flam3s:
I have a similar no brand head unit with the 9358i processor and made it work by rooting, then setting dpi to 200 with joying extra tools and finally downloading the google contacts app.

First time it will say that there is no app to handle the request but you have to choose it from the 3 dots next to the calling request on screen.

Still tweaking it to work perfectly.
[Android Head-Units] davemazo:
Google assistant

Thanks, I did see that but after reading the thread on rooting it put me off a bit. I don't fully understand all the technical talk
[Android Head-Units] Crimson Flam3s:
It's actually very easy.

You just have to have a clean usb and save all the zip files on the OP on it, and simply connect it to the USB port/SD card and it will auto restart and root.

That also includes the Magisk app which is what would manage and allow root access to apps that need it, like Joying tools.
[Android Head-Units] davemazo:
Root

I'm sure you're right but when I see comments like the following

"And because of the possible "but": You need to create a new boot image per new firmware version. So if Joying releases a new firmware and you flash it, you better not use your already created boot image, but create a new patched boot image."

And hear that some members can't use their microphone after rooting it sets alarm bells ringing for me. Along with the worry that not really knowing what I'm doing I'll ruin my headunit which apart from not being able to make calls using "OK Google" is working fine

I have bought this head unit but it has a lot of static noise. Joying with spdif intel 4/64gb

here is a short video:

i have no rights yet to put a youtube link watch?v=VQhH84rNihw

I do have a VW Tiguan with Dinaudio i believe it has some kind of amp, I tried the unit on a normal speaker sistem with no din audio it does have a small white noise but it is there also.

I have 2 questions:

Is this unit broken?

If it's not broken what can I do to remove the white noise?

Is there a DSP converter that has FL FR RR RL?

Thanks!
[Android Head-Units] NRGZ28:
Mine has white noise as well when above "0" volume. Was hoping SPDIF would be better, but apparently not ?
[Android Head-Units] merl1:
So, got my Joying head unit in end of the summer, but opened the package and starting to install it only now. Actually, I my head unit has NO SPDIF on the back panel.

I can't post link here but it for honda cr-v 2012-2016 version octa core 4gb

I pretty sure, there was a some words about spdif, but now only picture with it left. Thats very sad, because it was only one reason why I needed this HU...
[Android Head-Units] cycfari:
Both my volume control and steering wheel volume works with SPDIF output. However when I played 24bits or DSD,DFF files with Poweramp, it shows 16 bits /44.1kHz, Seems like Audio is first routed through onboard DAC (explains why volume control works)then to SPDIF out. So there's actually a degrade in the audio source.:(
[Android Head-Units] NRGZ28:
Is the audio output through the SPDIF port any cleaner ? I feel mine doesn't get loud enough through the regular RCA jacks. I have to use a line driver from audio control to get a clean enough signal to my amp.

Speaker level vs SPDIF

Hello all,

Thanks to watching guimond47's youtube vids, I've recently ordered a JY-BO124N4GS, which is the model specific to the BMW e90 cars. I was wondering if anyone has any comments / results from comparing speaker level outputs perform compared to the SPDIF out?

Also, I've learned that the SPDIF is stereo signal. I currently have a 4 channel amp / DSP using speaker level inputs (FL,FR,RR,RL). If I decided to go with the SPDIF into the amp, I'm guessing the amp/DSP is set up to recognize the digital signal input and split it into the 4channel outputs?

:good:
[Android Head-Units] thierry34:
if you have a spidf input in your amp,there is no problem. what is the reference amp ?
[Android Head-Units] eas66:
It's an Audison 4.9bit. It has an optical in, which means I'll have to get a coax > toslink converter. Not a huge problem, but its a cost and a bit of a nuisance running the cabling. While it'll be nice to listen to high res audio in the car, I'm just trying to work out how much of a difference it will make. Using the speaker outs would be very handy, if the signal is good enough.
[Android Head-Units] thierry34:
have you seen this one ? https://www.youtube.com/watch?v=B14vDK0SRNY&t=1067s
[Android Head-Units] eas66:
I did see that one, it's very helpful thanks.

What I was looking for was someone to conclusively tell me that SPDIF was very much worth the effort and cost that I'd need to bare by going that direction, or not.

In any case, I'll have my HU today, and with a bit of luck I'll put it in over the next couple of days. I've decided that with an investment in a system that is capable of digital, i'd just go for it. I've ordered the bits I need to run digital into my amp and will be doing that in the coming week or so. I'll have the HU running off speaker outs for for enough time to make a non scientific comparison when I switch over to the digital.

thanks

Hello and a few questions

Hi All, first post on this forum so please be gentle!

I'm considering a Joying unit to replace my Alpine IVA-D310R as it is a bit long in the tooth now and doesn't do nice things like OK Google or Android Auto. Currently, my IVA controls my Alpine PXA-h701 5.1 processor via AI-net and digital optical, which is nice, but means that if I replace the head unit, my processor is no longer controllable (unless you have the RUX-C701 controller, which I don't). Even with that controller, from reading around the overall volume control would be done by the processor, which means I'd need an annoying single DIN unit somewhere in the car just to control volume and processor settings.

I would rather send a digital signal to a processor rather than RCA's with inherent noise, which was the reason for looking at the joying unit. It also means less cable bulk to run - a tiny optical cable is much easier to run than 3 x quality RCA cables. (Yes I know I'd need to convert coax to optical for the Joying unit if I were able to still control the processor)

So, assuming I am going to use a Joying unit with Coax out, my questions are:

1) if I can't control my PXA-H701 processor anymore, what is a suitable (equivalent quality/function) replacement that can accept a digital signal? Ideally, this would be controllable by the joying unit via USB and an android app. Needs to have pre-out fronts (pref x2), rear, sub and possibly center, and be 4 or even 8v (preferred voltages for the Alpine Amps). I'm guessing that processors have improved quite a bit since Alpine released that one, so I am hoping that there is something that fits the bill.

2) If I do get a different processor, how would the overall volume work? I read that the coax output from the joying unit is PCM 2.0 stereo, so no separate subwoofer channel sent to the processor. Anyone had experience with what happens to volume and speaker/sub outputs from their processor when using a coax input of 2.0 stereo? Ideally, if it is only sending PCM 2.0, I'd like the processor to split that to sub freq's for the sub output and speaker freq's on both front and rear outputs.

3) If anyone has a processor with Android App support - what are your experiences with the Joying unit controlling it?

4) Assuming I can find something suitable, anyone looking for an IVA-D310R or PXA-H701?, :)

All thoughts and advice appreciated.

Nick
[Android Head-Units] thierry34:
i think your request does not concern this thread. your asking about dsp unit only !!! joying unit have a dsp but not with same quality as you want.

i have joying unit with an external dsp (waveflex A8 dsp) with spdif connect. i use volum control of joying unit. it's my dsp which separate frequencies to give the good signal to the right speaker by an amplifier as your Alpine processor.

i just have coaxial cable between joying unit and dsp .
[Android Head-Units] ^Nick^:
Thanks for the reply - I did think about starting a new thread, but since I am specifically interested in the Joying units that this thread is titled around, I thought I'd post it here. Happy for it to be moved, but I have no idea how to go about that...
[Android Head-Units] eas66:
From what I've read (and seen on youtube) the digital out volume is still controlled by the head unit. Is that what you mean? Or, do you mean settings on your Alpine DSP? If that's the case, don't Alpine have an app or softeware for DSP settings?

If you're considering a different processor on top of the joying, plus a coax to tolink converter, you can't be too far off the cost of just getting a new Alpine head unit that does what you need?

I'm running speaker level into my dsp at the moment and get the sub signal from front channels. The signal is then fed to the sub out on my DSP. I'd imagine it's the same for digital in.
[Android Head-Units] Kjekz:
Has anyone done a comparison of volume level between coaxial and rca?

Will the signal output from the joying be higher via the coaxial than the rather measly rca voltage?

I understand there is a processor in the other end that you can tweak gains on etc, but turning gains close to max to support a stupid low rca output voltage isnt what i would want to do. So if the coaxial signal is "louder" that would be nice
[Android Head-Units] eas66:
Just to update the above with my non-scientific experience on speaker level out VS SPDIF out on the JY-BO124N3 (8.1 Intel Airmont eight-core 1.8GHz SC9853i)

I have a modest system in my car which includes an Audison 4.9 bit (2*75w into passive 2 ways + 2*140w into under seat 8inch woofers ) and an Audison AP1 pushing around 500 watts into a 10inch sub. I had it all connected to the factory BMW head unit, which was an alpine (made for BMW) that was rated at 4*15, or there about. The factory head unit sounded fine, but lacked features and frankly was outdated. I opted for the JY-BO124N3 as a replacement. Stuck it in last week used speaker line outs as signal inputs into the amp.

When my cables and coax > toslink converter came to use the SPDIF, I did some simple testing using HI RES audio files and unfortunately my 48 year old ears heard no real benefit of the SPDIF over the speaker level. If anything, with my system the results where a downgrade due to the drop in input level voltage. With all gains set to max, I couldn't get the same volume out of the SPDIF.

It should be said that neither set up gave any distortion. I was surprised at how much better the joying sounded over the stock alpine head unit.

I’ve gone back to the speaker line inputs now. I’m not saying there isn’t an advantage to using the digital output on the head unit, I’m just saying in my particular set up it wasn’t an obvious advantage. It could be that I didn't give the SPDIF a reasonable chance to impress. I might try it for a week and see if the switch back makes the difference more obvious.
[Android Head-Units] Ziggyrama:
Hi guys, this unit looks very promising. I think someone already asked this but I didn't see an answer, does anyone know the max sampling rate on the digital out? I think the video showed 48kHz on the receiver. Is this as high as it goes or was that a limitation of the receiver? I would love to see at least 96kHz/24bit rate. I have a Zapco DSP which is fed by a Clarion HU over TOSLINK but I would love to step up to a nicer functioning HU and not lose the digital signal.
[Android Head-Units] ^Nick^:
Update to JY-VO131N4GS testing via SPDIF

Hi guys,

Thought I would post an update to my install. Having run all the necessary cables to use the SPDIF out of the joying unit, I have noticed some irritating issues.

First off, the AMP control cable does nothing. Always 0v.

Secondly, when using the SPDIF out to a processor, then amps, then back to the speakers, there is no Keypad tone output at all, regardless of the setting on the headunit. Music is fine (files, youtube etc) but no keypresses, even when music is playing.

I contacted Joying about both of the issues, and this was their response:

>>>>

1) For the amplifier connecting, please connect our ACC wire with your amp wire.

2)The SPDIF only the sound processor, it is shown the sound effect for the music.

So no matter you connect the SPDIF or not, you also need to connect the speaker wire. then you can hear the toch screen sound.

Hope it will clear for you. if not, please inform.

Thanks

<<<<

Really? connect two sets of speaker outputs to my car wiring?? Four cables from my amplifiers having been fed from the SPDIF signal through my processor, AND the four speaker cables from the headunit itself?? Are these people *****g insane?? The reason for using the SPDIF is to AVOID using RCA or, worse still, high level speaker output. Sodding Shenzen junk. I am wondering what other sound I might be missing through SPDIF which will be my next question to them. Additionally, the 'boink' noise from google assistant to advise you it is listening is extremely hit and miss, sometimes there, sometimes not.

I replied to joying asking if there was a firmware fix to allow all sound to output through the SPDIF, with their response:

>>>>>>

Really sorry, there is no firmware can solve your situation.

Because the original design is that.

It cannot all the sound come from the SPDIF. sorry.

<<<<<<

WTF Joying?? Shoddy state of affairs. If I hadn't spent so much time installing all of this, I might have sent it back. Now I will have to live with missing keypad tones (not that it is a show stopper) and an intermittent google 'boink'. One other minor annoyance when trying to set mobile APN's is that the screen is so dark you can barely see the settings that you need to edit. And why does it think it has 2 SIM card slots??

Having said all of the above, the 9 inch screen, built in 4g sim slot and wifi, voice control over youtube, google assistant, native google maps, the ability to listen to DAB radio, Spotify, Flac files from usb harddrives, The Torque diagnostic app connected via OBD2, Android Auto/Apple carplay (if you want it), and remappable steering controls make this unit pretty awesome to use.

Just wished they'd spent the time fixing the missing sound items through SPDIF and quality checks (APN settings), and I wish I understood enough about coding to fix their ROM mistakes.

Will update if I get anywhere with fixing the issues.
[Android Head-Units] rigattoni:
The Amp control cable needs to be switched on in the factory settings.

...and this switch has a delay of ~1-2 sec until the cable delivers +12V on boot.
[Android Head-Units] ^Nick^:
Thanks - The setting is on and the unit has been rebooted numerous times. Still 0v. I tested it thoroughly before contacting Joying. If you have the same model as mine and the Amp control cable is working I would like to know about it, because I will reply to Joying.
[Android Head-Units] rigattoni:
I use the EU-JY-UO128N3 just now in my car and due to missing external Amp, I use the Amp Control cable for running my cooling vent in the unit.

...and yes, it´s working, easy to switch in the settings, because I normally don´t need the cooling in wintertime.
[Android Head-Units] ^Nick^:
Mine is a JY-VO131N4GS and it definitely isn't working, just retested again with AMP control setting both on and off with a reboot in between each, and no joy. This unit does not have settings in developer options for the Amp (external, internal) - it is just within the normal settings controls and only has On or Off.
[Android Head-Units] rigattoni:
In this case use the antenna power line. This should work too.
[Android Head-Units] thierry34:
do you connect your amp with the amp control cable ? is it different that the antenna cable (blue) ? (what color is this cable ?)

i connect my amp to the antenna cable (blue). but when unit turn off, it wait 5 minutes to turn off amp and external dsp.
[Android Head-Units] rigattoni:
There is a wiring sticker on the unit. I don´t know it out of memory. The unit is mounted in my car, so I am not able to have a short look at it. I use the AMP cable as power for the mounted fan.

Please serve yourself by a look on the sticker. ;)

That there is a delay in turning off is related to the time the unit needs to reach deep sleep.
[Android Head-Units] acidikjuice:
Sounds good!

My SPDIF Review:

I have a Joying with SPDIF out. I also have a MiniDSP 2x4 HD. I used the MiniDSP with my Nexus 7 car audio install before the Joying. The Nexus used the MiniDSP as a USB DAC and it worked well, digital all the way to the amp. I never wanted to get any of the Joying HU because they could not use a USB DAC well (there are some units that this was eventually enabled). But the SPDIF output from the new generation of Joying also sounds amazing and I get digital all the way back to the amps as well: so game changer!

I did need to get a COAX SPDIF to TOSLINK optical converter because the MiniDSP only takes optical, USB or RCA input. But this was only $15 on Amazon and the SQ is still great (and no reason the converter should impact this). There is no button tones on my SPDIF output and that's 100% fine with me. The EQ and other DSP processing on the headunit seems to work well on the SPDIF output. I am using the MiniDSP for most of the filtering, timing and equalization, but it is also nice to make minor changes/test directly from EQ/DSP app provided by Joying. This is a great setup and really overcomes some of the flaws with the cheap amps and RCA line out sound quality on typical android head units. Yes, the MiniDSP alone is $200 but even the cost of the HU plus MiniDSP is still around the $500 mark (USD) and the system is a great value!
[Android Head-Units] thierry34:
i have same configuration, but minidsp 2x8 . i'm very surprise by the output spdif quality.
[Android Head-Units] acidikjuice:
I was surprised too. I used the RCA output to hold me over for a few days and it was not great. Nothing compared to using the MiniDSP and digital out. I think the internal DACs and preamp in Android HU are noisy and lower SQ then most non-android HU. This has really made them so much better!
