Joying 5.1 HU, USB connections

Re Post from MTCB forum,
Just installed a Joying:
. SKU: JY-UL124 . Quad Core Android 5.1.1 Lollipop OS Capacitive 7" High Definition for Universal Double Din . CPU: RK3188 1.6GHz Cortex A9 Quad Core, Resolution 1024*600. RAM：DDR3 1G, 16 GB memory
To my 2014 Australian Hyundai Elantra.
I waited to get the latest HU from Joying that has an unrated mother board and USB/ Comms board. With Lollipop 5.1.1. the unit performs very well with none of the problem previously mentioned on these pages. The internal and external mics are clear and the Bluetooth systems are perfect. Unit has been rooted and I don't seem to need for apps so I won't changed the software now.
The dimming for the button and the screen to follow the vehicles rheostat was fixed by making a circuit to invert and amplify the rheostat output to the HU ill line. Work's well, Kudos to the guys at the Subaru forums.
I had one bug fixed by Joying when the GPS nav was muted whenever I plugged in the DVR front camera. Joying quickly sent me a link to re flash my firmware and the problem was fixed. I have them currently looking into a bug when I view the DVR input shown on the HU I get lots of flashing to the screen in all pixel settings. I have been told this will be fixed in the next firmware update soon.
One problem that I can't solve is when I try to use my vehicles Multimedia Jack located in my center console. There is a Aux and USB jack there. All wiring from console to HU is complete. If I connect a USB stick to the Jack in the console then then HU struggles to connect and gives up. If I interrupt the USB plug and socket behind the HU then I am able to use the USB correctly. Looking at the car wiring diagrams there is a amplifier cct behind the Multimedia Jack supposedly to amp up the USB to HU. Doesn't seem to work?
Any ideas appreciated.

i have nothing to add, other than interested to see what the result is. Are you saying that your car comes with a built in hub in the console, and you are trying to make that USB port in the console work to the Joying head unit? my vehicle is similar, and I would like that to work as well
Update
Yes I have a console hub I guess.
The book calls it a multimedia center. Just an Aux port and a USB port or Jack in the tidy bin in the center console. If I by pass the Jacks and directly put the USB stick into the USB tail from the radio then it works fine. When I plug into the console port it tries to read it and fails. The HU then reports a read fail, have tried other known working USB sticks.
I have inspected behind the console jacks and found a cct board attached to the Jacks and then to the car wiring. From looking at the diagrams of the car previous to mine I see a cct board containing what looks like an amplifier. Tracing the car wiring to the radio input connectors seems to be OK and the wiring correct. Voltages at the radio connector are right in that there is 5v +ve, negative - earth and the center pins are data as they should be.
The console Jacks

The wiring for same (mine is same but more complex)
w.hemanual.org/multimedia_jack_schematic_diagrams-2036.html
Really bugs me not to be able to access that USB input Jack esp as the radio is a great unit.

You need to post this question in the MTCD (Lollipop) hardware thread. This thread is for MTCB (KitKat) units. The hardware in the MTCD headunits are very different than the MTCB headunits.
Thanks and done - I still have the same problem

Hello, i'm interest in tthis unit,https://www.carjoying.com/quad-core-android-car-radio/quad-core-vw-android-car-radio/joying-2016-latest-aftermarket-european-warehouse-lollipop-android-5-1-1-car-head-unit-autoradio-quad-core-double-din-gps-navigation-system-stereo-radio-support-reverse-camera-dvr-g.html and dont' know if it's the same you have. Can you tell me if you have some lag problems or something? does the hardware handles well the software?

Bob
Seems the same. Same CPU, platform, Specs etc. I think being a "VW Golf Passat Jetta" model from Joying it probably has some firmware in it to pick up your particular car's Bluetooth connections. The front surround looks like it has been added to my "Universal" type to fit neatly into your dashboard. The case and rear connections are identical. I see they have added a CanBus box which my car did not need but looks like yours does. There is probably a harness with it to fit your wiring loom.
if you run a lot of apps at once there is some lag not bad though. Like if you had the radio on and the GPS on and DVR the traffic then that's a pretty big load so then there is some lag but you get used to it. You might have to wait a second before an icon or screen switch becomes available. When running only a few apps at once there is no lag issues.
I like mine a lot, would not replace it with the OEM.
The problem mentioned below is one with my car only. My car's remote console jacks for the AUX and USB have their own preamp so I have by passed them and put in a aftermarket remote Aux USB and that works ok.
I am half way through doing a write up on the modifications and install if anyone is interested.

Hey mate, does it run Android auto? Trying to figure out which units can and can't. Looks like any running Android 5 can but trying to figure it out. Thanks!

Android Head Unit SC9853 - Nissan connections unsure...

SC9853 8-core Intel Airmont with 64GB / 4GB ram... bought it online... supposed to be suitable for my car model, but I'm a bit unsure, and the Chinese seller did not provide much help yet... no instructions nor manual nor wiring diagram...:
my original car: Nissan Teana 250XV from 2010 (model J32, matches the Maxima A35 dashboard/equipment)
So the top LCD display shows the CD number / Radio station / dual Aircon temperature setting.
The backside Radio/CD player:
(deducted the connections from a Google image from Nissan Frontier)
the dark gray is the Antenna radio, the small white should be the Steering controls, the bottom big connector should be for the AC (should not touch), and the remaining plug is the power/speakers wire.
The 2 connections that went into the top LCD display:
I'm assuming the black one goes into the black connector of the Android harness:
I found similar connections on another post, so I deducted:
It came with 2 USB cables, 1 is 4 pin, the other is 6 pin connector... 1st thought they go at bottom in middle, but from the other post it was for MIC-in ?
it should come with instructions and a wiring diagram?!
Can somebody help with explaining what's what?
it seems the harness has a male and female connector, so the female is to connect to the car cable, and the male goes back into the CD/Radio? so the CD player can still function, it's audio should go through an Aux cable?
The antenna cable has not suitable connection, so I suppose I can keep using the stock radio? there's a cut blue wire on the harness labeled Auto ANT, so I could connect this one to the car cable, though would need to figure out how, looks like it has 2 wires (below is for the newer version model L33, but Radio ANT connection looks identical):
Assuming only 1 of the 2 LCD connections need to be used, one of them is black, so I'm assuming this one goes on the black one of the harness...
Sure hope I can sort this out... biggest issue is the head unit seems to be too long to the back, so I have not been able to reinstall, it sticks out... if I install the GPS it sticks out even further, without the GPS this is how far I get....:
the seller claims it can be installed, they did it before with this kind of unit... so shall try again, but to me it looks like I'm hitting the back of the compartment...
Freaking out as have spent 380 USD on it and it took 2 months to deliver (due to Chinese new year / COVID-19)....
Any help much appreciated, thanks a lot in advance!

If the unit has been special been produced for your car, it should be plug´n play.
All connectors are coded. You are not able to misuse any of them.... So what is your problem now???

Well for one besides the unit turning on nothing works: no sound, also the old radio not working, only short beeps when pressing load/eject CD.
To the Head unit I only connected the main power cable, this one also holds the speakers? So should have sound?
Tried setting the steering wheel controls... Also no luck..
Will try to also connect the brown-blue/white cable which has pin count matching bottom left socket below the RCA socket.
Issue may be this Thailand Teana, steering wheel at right side, most units sold for left side...
You mean coded as in wire colors should match? (Only a few cables are labeled, the sockets are not)
Thanks

ok the seller now confirms these are the connections:
the not marked left bottom and right top supposedly have no function...
Only thing left to try is to disconnect the original car stereo plug, so the Android head unit is connected directly to the car cable without the car Radio connected... but that means the original car radio/cd player is not usable...
could also try to use the AUX cable from the Head Unit's RCA connections and connect it to the head jack of the Radio, suppose should get audio then?
will check the wire colors, suppose they should match the harness wire colors? if the unit would actually physically fit my car could correct the socket wiring so it may work for my car?
(I'm assuming a left hand drive car may have different wiring vs. right hand drive car? as nothing works, except for the screen getting power (no sound, no steering wheel control))

That means that the connectors of the cable tree only match to one single hole in the unit.
That has nothing to do with colors of the cables itself. They most probably don´t match.
Just do it, or drive to someone who is able to help you.

yes, you are right, each cable has a different unique fit, not interchangeable, but for the AC cable there are 2 wires it both sockets going to 2 pins, but only one of them matches with the harness connector (so the other wire has no counterpart = dead end due to on different pins), so possible wrong wiring in the harness?
if it's truly plug and play, I should have at least sound, I have no sound... so something's wrong... or does the software need configuration to enable sound?
for the steering wheel controls there's a menu to configure the buttons, but nothing happens, there is however a setting to change the impedance, maybe should try that next.
what about the Canbox?
its purpose is normally for it to act like it would be the car, what's its role here? why is it needed if it's installed in the car? I read online normally it's used to diagnose without the need of the physical car to be present.

The CAN-Box is most necessary part in the set up.
It provides Ignition, power for the amp and the possibility to use the steering wheel buttons.
I would say that you should drive to a car repair shop to get it built in.

Do you have a link for the unit?

Seems seller may not know his own device:
Looks like mine, so the cable I didn't connect could be the CAN input.
Will try later on
Seller wants me to go to a shop where they'll cut out a part of my car to make it fit... Should I? Rather keep everything original....
Says this TS9 always is bigger size for heat disapation...
This is the link where I bought it:

There is too many of these units out there from sellers that don't give enough information with their products. It leaves the end user scratching their head all too often. I purchased a very similar unit to this. Same thing, no support, no instructions, no manual etc etc.
Did you get it to a shop and were they able to sort?

no, I returned it, as I don't want to cut a piece out of my car, and other sellers say it should not be necessary if the correct unit is installed.
The seller thought me to go to the "Extra Settings" menu to select the right car under "Model", after which it updates the MCU accordingly. After this the only thing I got working was the AC temperature control on the screen, had to set the "left / right Peptide" differently to mirror temp setting so Dual setting matches (left and right is apparently the other way around in a left hand side driving car ("peptide" must be a bad translation as that's part of a protein...).
Is the RCA jack to AUX the only way to get sound through the car speakers? (didn't work either, never got sound... I believe the cable was jamming the original CD/Radio, which didn't function with the head unit in between)
glad I got my money back, and recently found a shop here in Bangkok that can sell and install a proper unit, pheww...

Confirmation on wiring 7862 to Kia Sportage 2011 with digital amp

Hi all, I have an Australian 2011 Kia Sportage Platinum model - I think it was SX / highest spec model in other countries. Apparently the Australian car in 2011 was a little unique in that it had a 6 stack CD but no sat nav on the head unit. There is a factory digital amp and sub woofer located in the rear. As much as I have attempted to get this fact across to suppliers on Aliexpress, I am sure they did not fully understand and have suggested I only need a CAMBUS and I am good to go.
As you can see with the pinout for my radio on connector A I have SPDIF ground, DN and DP. So it is a discrete signal to the amp that decodes what I assume is PCM and then sends it off to the speakers. I have a few questions:
1. Before I install the 7862 Unit, I will check voltage out from Pins 6 and 15 on my factory radio with sound on. I assume this will be less than 5 volts. as per SPDIF coax spec. I will then connect up the 7862 unit, plug in an RCA to the COAX SPDIF out and check voltage. If the wiring loom that I have been sent doesn't work, this COAX out feed fed into my car's wiring loom along with a 12v signal on pin 14 (remote AMP) will get me started. Any thoughts?
2. On Connector A of my original head unit, there are the SPDIF outs but why are there also speaker outs for front and rear left and right if there is a digital signal to the amp? Does this mean that the amp is only feeding the sub woofer and that the fronts and rears are fed directly from the head unit? It seems very strange to me.
3. PIN 9 on Connector A is DETENT. What is that? PIN 14 is Remote AMP. Is this a 12v line to wake up the amp?
4. Chinese Unit wiring shows a CANBUS but I am unsure is the CANBUS has an analog to digital converter? Can anyone shed light on this?
I appreciate any assistance you can offer.

This could help regarding SPDIF: https://www.gencoupe.com/threads/help-spdif-preamp-input-nav-premium.106094/
Are you sure the China head unit has an SPDIF output?
I think your OEM radio supports both. SPDIF and analog output. Or there is a cheaper variant available which only supports analog output. You don't need this connectors when using SPDIF.
I don't know Detent but in another forum they just ignored this pin.
Remote Amp is 12v signal for the amplifier. So you're right.
The canbus converts digital signals from your car to the radio. E.g. Translates the steering wheel buttons to a signal the head unit can interpret.

Hi, thanks for the link.
I am sure the chinese unit I purchased has SPDIF out via TOSLINK and coax but not through the main head unit wiring.
There definately is a cheaper model of my vehicle that didn't have a digital amp but I am suprised that there is both direct digital signal to the amp as well as direct wiring to the speakers. It is very confusing.
I understand CANBUS has a high and low signal but I wasn't sure if they specifically also change digital audio signals as well as well as the standard CAN signals.
I believe some CANBUS may handle both the CAN high / low transfer and have the ability to to convert the analog signal out of the android head unit to an SPDIF line level PCM (assumed) signal that my amp needs.
I guess this is not a common subject here. I might have to wait and do a fair bit of testing before I install.

Connecting a china head unit can be a real challenge, especially because there is zero support from the seller.
I've seen the amplifier has separate inputs for navigation voice (pin 9 and 23). Sorry for the German link:
Kia Sportage - Externer verstärker Bauteile und bauteile-Übersicht - AVN-System
Maybe some audio signals will be transferred analog. You could connect the new device without the analog audio connections to check if they are really required.
Can't help you regarding CANBUS but I hope you keep us updated and give some updates of your "project".

Thanks again. The problem I have is that my head unit has SPDIF out, USB out rear cam out but all connected to the two white plugs. This unit seems different to all the US, Europe and other Asia models. It might be why I am getting so many blank stares.
I'm even having trouble finding an Australian edition of the wiring diagrams.
Your helpful link to the QL model German manual also has an SL model which is my model. Unfortunately my radio is not amongst the option in the manual. I see radios offer Sirrus so I am assuming that is a US model.
I might just need to go back to first principals and really understand my head unit before I do any installing. How is your install going?

My installation was a little tricky because I found three wringing diagrams which could be the correct one.
Fortunately all the wringing diagrams had ILLU and REVERSE on different positions so I was able to identify the correct one with a multimeter. But I wasn't able to find the wringing diagram with the model name of the device.
I have a Kia and finally the needed wiring diagram was from a Hiunday device. Someone crosslinked from a Kia forum to a Hiunday forum.
I had to completely re-wire and enhance the black plug of the China head unit because AUX and MIC are separate outputs on the China nav unit.
On the other side I had to remove USB from the black connector because this is a separate plug in the Kia.
For you the USB pins may are another good pins to check if the writing diagram is the right one.

I'm sure you already found this regarding the DETENT mystery:
Any radio wiring experts know what "Detent" leads are for?

But I think DETENT is PARKING/HAND BREAK. So that's easy to verify.

Yes, I will be doing a double check of everything.
I *think* that I have worked out why there is SPDIF line level + and - to the amp as well as wiring direct to the speakers from the factory HU.
I *think* that when I use and AUX input from USB or 3.5mm which is analog input, the factory headunit does no conversion and just amplifies the analog signal and sends it to the 4 main speakers. It will be simple to check this.
If I am correct, only CD and radio singal gets converted to digital line level SPDIF PCM then gets sent to the amp.
As my radio has a COAX SPDIF out, I might be able to make a single RCA to double RCA cable to send the signal to the amp. Or I might just patch in the SPDIF COAX RCA into the main ISO plug directly. I think having the COAX SPDIF out from my new HU will give me a lot more option.
I need to check if the CANBUS converts the analog signal to SPDIF line level or if the Chinese wiring just bypasses the amp and sub woofer or does something else again.
My new HU will arrive tomorrow of Monday so I will get time to study the wiring and make some checks. I will be sure to document all of the things I find. I just need to make the time to do it.

Well after a quick plug in and test, I am not getting any signal to amp regardless of how well I have followed the supplier's suggestions.
I think the standard signal to the amp id not happening so the amp is not waking up.
Canbus is for a 2015 Sportage but steering wheel options work with the volume working in opposite.
Will investigate more tomorrow.

Installed the radio today. The radio supplier's suggested installation did not work as I was sure it wouldn't.
After considering options, I chose to use the coax out and patch that into Connector A pin 6 (SPDIF DN) and pin 15 (SPDIF DP) and everything worked fine.
Some things to note:
1. Canbus worked although the steering wheel volume controls are reversed. Not sure if that is easily changable. I might just live with it.
2.The supplier actually sent me quite a bit more than I was expecting. There were extra patch cables and an external mic. This was nice, but I actually bought a mic thinking that one did not come with the kit. It was only a few dollars though.
3.There is very little installation info. The info by way of photos I was sent did not match the cabling that I had.I would have liked to get an understanding of all the pin outs including the CANBUS but I am yet to receive this.
3. I actually removed my factory radio last night and just powered up the unit. I didn't realise that the default setting in the software is to only put the unit in standby or only turned off the screen. This drained my battery over about 18 hours. I needed a jump start to get the car going and I now have the battery on a trickle charge to repair it.
This default setting allows instant on for the radio. By changing to the option for a three second delay, the radio needs to boot on car starting.
4. Boot times are quick. I have not timed it yet, but I would guess 20 seconds. Bluetooth connection takes about another 20 seconds after that. I will make a video of it and more when I have used the unit a bit more.
5. The radio fascia brackets weren't installed properly. Just make sure to check them before you install. The screws really should be a bit longer to stop threading the fascia mounts.
6. The fascia is not a perfect match for my dash in colour but it still looks good. The fit is not perfect but good enough. I might remove the dash again tomorrow and just pack one side of the fascia so it is more flush fitting but it would only be 3-5mm.
All in all I am very satisfied. The response of the unit is great and sound quality seems good. Bluetooth and wireless connected well and a quick test of the 5ghz frequency wifi tethered to my phone gave 6mb/s when I was downloading the Waze app. I will test more soon.

To 1: Isn't there a setting in Android car menu where you can assign the buttons to specific functions?
To 3: same topic here. I can set Sleep to on or off. But can't set time how long to sleep before shutdown.

There is that function and I did try to use it. I was long pressing on the physical button before pressing the on screen as suggested but there was no change. I assumed the button remap is only useful for non Canbus driven buttons. I could be wrong, though.

I Installed in my SL Sportage Platinum today and have no sound and no reversing camera. Do you have a photo of how you wired from the SPDIF on the unit to the factory connector?
Did you keep the factory camera? If so, what did you do to get these working? I think my unit is slightly different as I don't have the small clock.

Did you use the coax out method? The Kia amp requires am PCM digital signal sent on two wires as mentioned above.
Get an RCA male male cable. Cut on end and strip until you see two bare wires. These bare wires will patch into Connector A pin 6 (SPDIF DN) and pin 15 (SPDIF DP) of your car's wiring loom. These are the wires to the amp.
Add this male connector end of the RCA cable into the RCA digital out on the head unit. Check for sound.
My reversing camera is built into my rear view mirror so the wiring is not connected to the radio. And yes, I found the switch for volume, but thanks for letting me know. It might help someone else.

Success!!! I was able to get the amp working thanks to this thread. I was also able to get the camera working by splicing the 'unused' green reverse wire from the supplied harness to the brown reverse signal wire in the CANBUS connection. (I noted that in the some of the offical images the wire was pink.)

Peeps, did you have to connect the remote amp (12v positive?) or SPDIF ground (12v negative?) I’m almost there just no sound.. I’ve connected coax out to pins 6&15 but nothing

From the modifed coax cable coming out of your head unit, what voltage are you getting on either wire when playing audio?
If you aren't getting a signal, then there is a software setting (that I can't think of right now) or another issue.
And I have not connected the remote amp wire. Clear photos help a lot if you have followup questions.

Zero volts

Then the headunit is not passing a signal to the spdif RCA out for some reason

So i recently ordered a Teyes CC3 for my 2015 Honda Civic SI. I was told before that it would work on my car because it has premium audio and the connectors are different. They told someone else it would work plug and play and they sent him a 201t CRV harness and it turns out it didn't work. So Teyes agreed to send me some extra stuff for free with my purchase of the head unit and in return i would help them figure it out. I have background knowledge as I am an automotive technician by trade. However, a lot is lost in translation from Chinese to English.
So i haven't gotten my unit yet but the other guy that bought it first said his powered on but didn't have sound. Well that's probably an easy fix as he didn't power the amp. The bigger issue is that he said the reverse camera, side view camera, and the information display did not work. So i was able to find the manufacturer website for the canbus decoder and also Teyes sent me a PDF file that says how to wire it up. The issue is that the manufacturer of the decoder translated some of the definitions into something else and the wiring for the CRV do not completely match the wiring for my car. They have some pins listed and on my car it shows as not used. Anyone here have experience with wiring these things?
The ones i am most confused about are labled BUS+, and BUS-. I believe these go to the information display and might transmit information such as time and audio information. These are not the can network as there is a CAN_H, AND CAN_L pins. There is also SWC_A, B, and C. I believe these are for steering wheel control. BRAKE_OUT and REVERSE_OUT i believe are outputs to signal the head unit the car is in reverse to activate the reverse camera screen and to notify the unit the handbrake is off.
nit the ones i am completely lost with are labeled RXD, TXD, B_CTL IN, RCAM_CTL IN, and A_CTL.
aMy idea what these last ones might mean? Maybe A_CTL = AMP CONTROL. RCAM_CTL IN= INPUT FOR REVERSE SIGNAL???

Navtree Head Unit Battery Issue

Hi, New to the site and a greyhead who knows nothing about the electronics of these things. I installed a Navitree Y1E Android 11 4core 2+32GB Car DVD player for Ford Focus 2 2004-2011 audio for car video AM FM RDS 4G WIFI BT in my 201 Ford Focus. All appeared well as fitting was easy. All looked great and now I have found there is a constant live feed to the unit that is the possibe cause of a flat battery. My son is a mechanic and accepts he is not electronically knowledgeable, but he tested the wires and found a Yellow wire that was live and for memory, but there was a red wire that was permantly live and should be a switch feed. Can anyone advise if they have had experience with this model (Direct from China) and what is happening? Appreciate any help.

Hi Guys asnyone able to help. No help from supplier and looks like I will have to ditch the headunit..

Why would you ditch the head unit? It needs the permanent power on the yellow wire and a switched feed on the red wire. Your vehicle is currently not providing this so either you have wired the unit to the wrong feed or there currently isn't one so you'd need to find a connection in the vehicle which does switch with the key and run it to the red wire. As the red wire is only a sensing input it doesn't need heavy wiring.
It is not a head unit fault.
Note some vehicles supply the switching information to the stock head unit via the CANbus, yours may be like that and would explain the lack of a switched feed at present but you can easily overcome this.

Thanks
Mr.TT_NZ​Thanks for replying..appreciate comments..The red wire is going into the canbus via a 20 pin connector if it is cut the problem seems solved, so are you saying that I should have a switch cable run to that? See image for wiring.

Ah so you do have a CANbus module, I believe there are some issues with switching via those modules but I've never had one to play with.
You could try removing the red wire from the CANbus module and connecting a switched feed to it instead (not as well as) so the head unit only gets its switch control from your new wire. Maybe that CANbus module is not exactly correct for your model of car, there are so many variations even within a certain model that it is hard to see how the people who write the software for the modules can keep up with all of them.

Thanks again. I will try this...did a bit off research on the canbus and there is no UK retailer who will sell me a Ford canbus and guarantee it will work! Most said it would be a sale with no return.. Hey Ho..
