Just ordered this head unit. Pretty excited to try it out! Joying accepted an offer of $290 shipped from their eBay page.

https://www.ebay.com/itm/Joying-HD-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

Going to be installing it in my '05 Subaru Outback XT with the JDM double DIN kit with stock speakers and underseat subwoofer for now. I'll be upgrading the speakers later.

Thank you to guimond47 for the extremely in depth review of the head unit! Definitely pushed me over the edge into buying it. Joying should be throwing some commission your way!
[Android Head-Units] les_garten:
Watched your videos, VERY NICE!
[Android Head-Units] guimond47:
Remember all, if my review helped u decide to buy this unit. Please email joying and let them know!!

The FM quality is amazing. I had a pioneer, alpine, then another no name px5, then an eonon, all there fm stations had minor static in them. I was starting to think my antenna in the truck was messed up.

Then i tried this joying headunit and the FM is PERFECT. It sounds like im listening to a 320kps mp3 file. Its clear and sounds like a brand new car would.

I was very happy with that.

I have not tried calling.

Please report your bugs to joying support, the more feedback they get the faster they will fix it. Currently i was told by CAndy that ZLink cannot learn steering wheel controls, EVEN tho it has the option in the Zlink APP under settings. I was furious about this. Its carplay, it should have hands free capabilities... is there a APP that we can install that will force steering wheel controls upon an app. I thought I remember people doing that.

I do have one issue, only one of my usb ports work. The other only charges. Im gonna do further testing and swal the cords on the mother board. If it fixes. Candy said she will replace it or fix the unit.
[Android Head-Units] guimond47:
The volume works. Not the skip or previous button. This was only tested in tidal app. Power amp everything works.
[Android Head-Units] strawsy:
That's unfortunate. I bought one but will probably send it back if I can't get back/next working. Spotify is mainly what I'll be using.

[MENTION=1824007]guimond47[/MENTION] did you get a chance to look over some of the questions I had? I know its a little much but you would be helping me out.
[Android Head-Units] les_garten:
When you did your video, it looked like there was another USB header in there next to the 2 that it has now. You may want to ask Joying about that the next time you chat with them. Would be nice to have 3!
[Android Head-Units] strawsy:
Thanks for linking that thread. I was planning on looking through the forum and researching before sending it back. I'm just big on steering wheel controls and Spotify so without those I'm handicapped. I might try tidal but it wouldn't be my primary app.
[Android Head-Units] guimond47:
I am assuming this is for the 4G sim card adapter that did not come with my model... as for more then one usb. U can always get a usb splitter. It WILL work. (On the non Zlink port)
[Android Head-Units] guimond47:
Yeah i did. Sorry I forgot about it. I also have tooken the dash apart in my truck to do a special steering wheel modification.;) i will talk about it in the next video..
[Android Head-Units] guimond47:
1- yeah i can try that player when i have a chance this week. - i dont have flac files tho. Sorry. Im sure it will play just fine if the app supports flac.

2- spdif is 2.0. Stereo, left and right. Thats it. I answered this question in a post above. You dont wanna use a dac. U want to get a good DSP and send digital audio to it for the best sound experience. From then, you can calibrate the sound professionaly then use the dsp’s 4 volt rca pre out to your amps. That is the best way. We discussed that audio control, rockford DSR-1, mini dsp is good choices. Im sure there are more. Make sure it has coaxial input.

3- no idea on root yet. Will try and get firmware. But i dont know how to root the unit. If anyone can help with this.

4- i got it from the china warehouse, dutie fees was 20$ on 560$canadian. Took 3-4 days.

5- i dont daily drive the truck yet so im not sure.

7- dash/back up cam will only work as clear as ur camera quality. I have a birdseye view system and its pretty clear.

8- FM quality is superb on this unit. Best one ive tried yet. It sounds like your listening to a cd.

Sound quality is NOT an issue on this unit. Forget what you when through with all the other headunits with junk static or noise. This one is amazing
[Android Head-Units] checksum123:
No, It does not work with spotify, I do not have Tidal, but I am guessing the same.
[Android Head-Units] kouklo:
Thanks for the help bro! I'm going to pull the trigger and get it!

One more question, hopefully someone knows. $500ish plus another $400-500 for the DSR-1 is a lot of money upfront. I was thinking about buying the HU and getting a SPDIF to RCA that runs on 5V. something like this https://www.amazon.ca/PROZOR-Digita...8&qid=1550339954&sr=8-3&keywords=spdif+to+rca

Do you guys think it will work and can I power it from the USB port of the HU?

Also what kind of birdseye view system do you have?
[Android Head-Units] guimond47:
There is no point of running a dac. Theres pre outs , front,rear,sub on the headunit that work just fine.

Installing a dac does not yeild u any benifit. Although i did say this for the second time, i gather you will do what u want anyways.

The birds eye view is a noname one. Theres alot of them on ebay u can buy. As long as their 1080p their nice
[Android Head-Units] kouklo:
I promise bro I'm not "that guy" that doesn't read anything and just askes questions. LOL. Iv read every post in this thread.

The reason I want to use the SPDIF to RCA are 1st the only reason I'm getting this HU is for the digital out. 2nd When I finally do get the DSR-1 I don't want to pull everything out again just to add it. I already have all the wiring I need running to my trunk so it will be a simple addon.
[Android Head-Units] guimond47:
You can set ur car up like checksum did. Stuffing the dsp behind the dash was a great idea. Btw the dsr-1 is cheapest at sonix electronics. That way all your preouts are behind ur unit. Still wasting ur time with a dac. Theres one built into the head unit. Hence why theres rca pre outs.
[Android Head-Units] checksum123:
Agreed!

Why use a DAC, when the unit already has a DAC with RCA pre-out, the unit gives you 4 pre-out (FL,FR,RL,RR), while the DAC from amazon only gives you 2 (L, R).

One advantage of the external DAC (still to be verified?), is it might gives you better output voltage, since the RCA pre-out from the unit is only 0.5V, but it was pretty good when I was using it, and very loud when paired with a good amp.

IMHO, just save your money until you can get the DSP, then you can take full advantage of the Digital Out.

----------------

BTW, rebooting the unit fix the phone bluetooth issue, as one member pointed out.

Also, adding the external mic does not make any difference, the internal mic is as good as the external one.
[Android Head-Units] kouklo:
It's the 0.5V part that scares me a bit. you guys are right tho, the pre-outs should be fine. Before I install it ill probably bench test it and mess around a little.
[Android Head-Units] guimond47:
99.9% of all amplifers can handle up to .2Volts preouts. Match your rca to your amp gains. And your set. The human ear wont notice a 1volt preout to 4 volts.
[Android Head-Units] les_garten:
Indeed.

The amp I am looking at goes from 200mv to 18v on the inputs.
[Android Head-Units] guimond47:
yeah voltages never bothered me in car audio. i think its more of a money hype. since amps can easily match gains to up to 200mV. it should be a breeze. i also used the rca's on my eonon head unit before and it was fine.

Digital coax is just an amazing option/ sound. if you can spend the money and do it. Set it up properly with the dsp, you will be in heaven. Nothing compares to crisp instruments an detailed vocals.

I Got a email from candy and the big boss at joying said they were amazed with my review. they took my video and posted it on their youtube channel for more views. They also told me if i had any ideas to make the unit better then it is, to let them know.

I told them bluetooth data communication is a must( for my external DSP)

steering wheel controls on ZLINK carplay should work.

Any thing else you guys think theses units should have?
[Android Head-Units] piyush7243:
I would say a great review indeed. Improvement that we can look for.

Better amp

2v or higher pre outs

Better Bluetooth quality

What bitrate does coxial transmit. Is it limited to 16/44 or can do 24/96 or higher
[Android Head-Units] checksum123:
You did a great unbiased review that help a lot of people, that also persuaded a lot of people to buy it, including myself. I email the link to Candy who was taking care of my order, and gave her some feedback.

1- We need Bluetooth version 4.0 or above with aptx, they are using an older bluetooth chip.

2- Give us the ability to change the phone ringtone, and upload our own.

3- Make USB volume knob work. These new unit do not come with buttons anymore, so we are relying more and more on steering wheel control and traditional volume knob. I bought this volume control from amazon, and it does not work. I know about their bluetooth volume control, but it has delay and also battery operated, which i do not like. There is also a thread here discussing the issue with usb volume control not working, so a lot of people want this to work.

https://www.amazon.com/gp/product/B07HMNHYWH

4- Use better quality RCA connector on the back( gold plated ), something similar to this:

https://www.amazon.com/dp/B006IPH5H2/

On my previous unit, the whole outer shield of one of RCA connector came off as I was removing the cable. The ones they are using is fragile and looks cheap, sometimes you cannot push the cable all the way through as it gets stop by the frame., so it makes a loose connections.
[Android Head-Units] strawsy:
Well we definitely need the ability to control third party apps with steering wheel controls. I can't believe that's an issue...it almost defeats the purpose of having an android head unit. I haven't received my unit yet so I dunno if I can get it working yet or not but still should be standard. Bluetooth data communication would be a big one. Higher preouts but that doesn't seem possible or they would have done it already. Oem integration to keep climate controls, tire pressure and other features would be nice as well.
[Android Head-Units] les_garten:
I would say something that would make them standout is an easily detachable display. Something that you could hide or carry in the house. That way some Methhead or Neighborhood miscreant doesn't do a smash and grab thinking you left your iPad in the car.
[Android Head-Units] checksum123:
Ok, you talk me into it, I decided to keep the PLC2 Punch volume knob.

It allows you to control the Main Level, or Sub level, or Punch Eq from the DSP, I chose to use it for the Sub level. My other knob controller that came with my pionner mono amp is used to control the Bass response.

I like the fact that the Punch Level controller also tells you if the source signal is clipped by turning red, which is a big added feature, normal operation is blue.

The blue LED is very bright at night, very distracting, I am planning on putting some masking tape on top.

Still waiting for my frame from china so I can put the screen, right now it is hanging on my dash.

Here is my final audio setup.
[Android Head-Units] les_garten:
[MENTION=1824007]guimond47[/MENTION]

So the amp I am looking at has a Digital level control that has 2 wheels, one for "all" and one with sub level, as well as an LED to give status messages. Builin DSP. It is the JL VX1000/5i. Would you set the Headunit volume up as a limit and then use the AMP volume control for all volume control?
[Android Head-Units] guimond47:
That setup is gonna sound very nice!! Excited for you to have it all done ! Let me know the results!!
[Android Head-Units] guimond47:
I would set your volumes on the amp and forget it. Use the volume on the head unit where around 25 is a nice and loud listening number.

U want the main and sub to get loud all together and steering wheel controls too. Always use the volume on the headunit.
[Android Head-Units] les_garten:
The vol. control on the amp raises "all/master" volume and has an outer ring to tweak the sub separated. But the inner control wheel does them together. The impression I got from somewhere else was that if you eq the headunit, that as you change the volume on the headunit, your eq will only be good for one vol setting. But it you raise and lower the amp, that it would not shift the eq. So that was the idea behind using the amp output for volume. This may not apply so much for spdif, not sure.
[Android Head-Units] ch_swat_89:
How about the Bluetooth and mic quality in the new intel units?
[Android Head-Units] vamitul:
Hi.

i'm a long time lurker, but this is my first question:

Can the 10.1 inch screen be mounted in a vertical ("tesla-style") configuration? Does it work? I don't have enough space to mount it horizontally.
[Android Head-Units] les_garten:
Have you looked on their website? I think they have some Tesla style orientations.
[Android Head-Units] surfer63:
If you have adb over tcpip working, you can simply do:

adb shell setprop ro.sf.hwrotation 90

It will stay in portrait mode until the next firmware flash.

Please note though that only a few Joying programs will work in portrait mode. The rest is fixed in landscape mode.

adb shell setprop ro.sf.hwrotation 0

to put it back in landscape mode

This no longer works as of Android 8.1. It has been removed from AOSP.
[Android Head-Units] vamitul:
I was afraid of that. I'll look into the purpose-built vertical one: SKU: JY-VO101N4PX5S.

Does anyone know anything about it? Is the screen adjustable (via cable like the 10.1 inch)?
[Android Head-Units] strawsy:
[MENTION=4463220]checksum123[/MENTION] and [MENTION=1824007]guimond47[/MENTION]. Did you guys get steering wheel controls working? I can get volume up and down working or next and back but not all 4. Just 2 of the 4 will work. I can see that all 4 register in the JOYING steering wheel settings but I'm thinking I'm doing something wrong in the setup.

Also I have the unit with built in 4g module but so far its not recognizing my sim card.
[Android Head-Units] guimond47:
i have my steering wheels fully working for the joying applications and power amp. spotify and anything else is no go. is anyone formiliar with tasker? can we use this to interate steering wheel controls. Looks like we have some one in the forum that knows how to code. [MENTION=2550900]surfer63[/MENTION] can u change the code for bluetooth to let it allow data communication ? and do something about our steering wheel controls?
[Android Head-Units] strawsy:
I can't get back and next working even for JOYING apps. I'll have to mess with it more tomorrow. Once I get those working I plan to look more into getting steering wheel controls working for other apps.
[Android Head-Units] guimond47:
make sure to hit the check mark after you have assigned the controls. if not perform a factory reset and that should solve it.
[Android Head-Units] surfer63:
I can only do some basic coding.

It is extremely difficult to modify the Joying apps as we do not have the source code. It requires decompiling to smali code and make changes/additions. I do not know how to do that apart from the most basic changes, and don't want to invest too much time into it.

I can't change the bluetooth app to do what you want, but when it comes to steering wheel buttons: it isn't the bluetooth app. It is the "main server" app which is an app without gui. It is the 000000_com.syu.ms.apk on the PX5 device, the SofiaServer.apk on the older joying Sofia 3GR devices. I do not know what it is called on the new Intel Airmont devices (I didn't see a ROM yet which I could download). As the new airmont device is also a FYT based device it will work exactly the same as the FYT Sofia 3GRs and the FYT PX5s (not the QD PX5s). FYT makes 100% full java apps that are the same on all models and work on all models. They rely on the MCU firmware to do the "translations" to the hardware.

All buttons, be it hardware or steering wheel or via bluetooth, are controlled through this "main server" apk. As you can see from my signature I made some Xposed modules that capture some key events, but not the FFW/FBW/Play/Pause buttons as in general these always work. Issues occur mostly due to someone not using the proper CAN-bus protocol for his/her car as configured in the settings (ask Joying). Of course it can now also be a bug in these new models (still ask Joying).

For this reason I do not think Tasker, or one of the others like Ilama or Easer, will help at all in this case.

Using Xposed would require rooting of your systems, which should be fairly easy. Installing Xposed might be a total nightmare.
[Android Head-Units] talroot:
On the older Joying units we are able to access the "Factory Settings" menu using a 3 digit password. From there you can adjust sliders that control the volume level and it increases voltage output on the RCAs. Does this unit not have that menu with those options?
[Android Head-Units] strawsy:
My steering wheel controls are measuring the same on a few buttons so that's why it's taking the other preset away when I set the next one. Volume up reads 30 under the button, volume down reads 34, and next and back both read 7 or 8 so I guess they're too close to distinguish. I'm not sure what the cause of that is. I have a Chevrolet silverado and the swc wire is green. I'm using axxess awsc1 and going from awsc1 to key1 and key2 on JOYING. I switch key 1 and 2 around but it made no difference. I gotta figure this out and the backup camera. I'm trying to find the reverse trigger wire in/under my dash. Trying to avoid running a wire from back to front. My last setup I was able to use idatalink maestro so it was mainly plug and play.
[Android Head-Units] guimond47:
What year is the truck. U may not need axxes
[Android Head-Units] strawsy:
2016. I tried going straight from my steering wheel wire to key 1 and key 2. The values were just randomly jumping all over.

Wondering if this DSP1 would work instead of the others that are more $$$. Not an audiophile so looking for recommendations.

Off Topic

I don't usually do this, but you're way off topic, and not well targeted for what you are trying to do.

I think ya need to post that in DIY mobile audio or somewhere. This thread is about the Joying Headunit.
[Android Head-Units] rflores2323:
Ok just wondering if I need a DSP unit as I just bought this joying SKU:JY-UO128N4 and it's coming in next week. It says it has DSP built in .so I assume I don't need another unit like the parts express or Rockford unit. Sorry confused.
[Android Head-Units] les_garten:
You didn't ask that question in your post though. You asked us to review a certain DSP against others costing more, and if you are looking for DSP comparisons, this would not be the best place.

IMO, the DSP in the Headunit does not do what a "real" DSP does. If you are using the high level outs straight to speakers, it would work OK though.
[Android Head-Units] strawsy:
If you read through this thread you'll see that the Dayton audio dsp is kinda pointless with this head unit as it doesn't have coax input. Since this thread is mainly about spdif output you'll want to get a dsp with coax out. Which the top option price wise is the Rockford dsr1. I have one but haven't installed it just yet.

I ended up using the Bluetooth hands free buttons for back and next and they work just fine. It will take some getting used to but it works. I still need to tinker with getting Spotify working but first I need to get the 4g working. Right now it's not detecting any of the sim cards I put in. I've tried 3 total. I emailed joying and hopefully they reply soon as my dash is torn apart waiting to install this fully.
[Android Head-Units] checksum123:
You do not need Key2, just Key1 and GND, it measure the resistance between Key1 and GND.

I am using the Pac Audio RP4-NI11 ( https://www.amazon.com/Audio-RP4-NI11-RadioPro-Replacement-Interface-x/dp/B00H8YCSII ), I just connected the tip of mic to Key1, Power, GND, ACC, and my CANBUS signals (CANH,CANL).

All my steering wheel button work great, they register the proper value when I press the keys.

Also make sure your steering wheel adapter has an updated firmware, I had to update my firmware for it to work properly with my car.
[Android Head-Units] mahtew:
These Units should have kernel and rom sources posted on github!

It's one major flaw, that stops dev from developing and resolving issues like bt.

If they don't want to share drivers, they can add them as blobs but kernel sources are must!
[Android Head-Units] surfer63:
Which Bluetooth hands free buttons?

I have tried several with my previous Joying sofia 3GR and with my current Joying PX5. None of them work. (I have no steering wheel buttons in my car)

It could also mean that Joying (or actually FYT) no longer crippled the bluetooth drivers on the intel airmonts (previously on sofia 3GR and PX5 only allowing phones, odbd dongles and Joying bluetooth stuff).

---------- Post added at 09:09 AM ---------- Previous post was at 09:05 AM ----------

This only works on Joyings without CAN bus adapter. If you have a CAN bus adapter, you have logic on your motherboard reading the binary CANbus signals. If you don't have a CANbus you have logic on your motherboard reading the resistance. The cabling in the harness towards the plug connections in your unit is exactly the same, but end up on different hardware inside the unit.
[Android Head-Units] checksum123:
My car has CANBUS, but Joying did not provide the CANBUS adapter for my specific car, that why I had to get the PACAUDIO SWC adapter to interface with the joying.

I do not like the bluetooth adapter because of the delay, and also you have to replace the battery.

But it is better than nothing...

Well it was in park. I was going to connect the brake wire to ground but the directions said to not connect it and control it from the settings.

[MENTION=4463220]checksum123[/MENTION] did you connect brake wire?
[Android Head-Units] checksum123:
No, I did not connect the brake wire.

But I remember there is a setting to prevent viewing video while driving, it is turned on by default, I did disable it, I beleive it is in advanced setting or factory settings.

Did you try the built in video player?

--------------------------------------------------

Finally got my frame, and it is a perfect fit; my install is complete, I am very happy with the sound. Although not perfect, I highly recommend this unit. I have tried many android head unit, PX5, previous Joying, Seicane, Dasaita, and this one seems to be the best. I did a 3hr trip while playing music and using GPS, and it never skipped a bit.
[Android Head-Units] les_garten:
