Hi Tuuza,

I think the issue is more complex. First of all, my car is a newer generation so I had to use the following connector:

https://www.carjoying.com/joying-ha...roid-auto-stereo-volkswagen-vw-2016-2017.html

There are no blown fuses and I have checked that the unit (and canbus adapter) gets power.

Issue is that the CANbus adapter does not give the radio 12V on the ACC pin when ignition is on.
[MTCD Android Head Units General] tuuza:
I assume you tried with the connector plugged and not plugged, have you tried to change to the golf 7 can version?

[MTCD Android Head Units General] phatass_dk:
I don't know exactly what you mean, but I've tried powering it up outside the car which works fine.

I have tried changing the CANbus profile around a bit, but it occured to me that no matter what I change - the CANbus adapter will not change.

I mean - no matter what I do on the unit, the canbus box will not output 12V on ACC - or am I wrong?
[MTCD Android Head Units General] tuuza:
There is the orange wire that has connector and a clear plastic cover covering it. If I remember right, it has something to do with acc.

Make Joying send you a new canbus module. I have no idea what VW changed between the wiring during years.

[MTCD Android Head Units General] surfer63:
The problem is that newer VAG cars (VW/Seat/Skoda) only have constant 12V wires, not a constant 12V (BATT; red) and a switchable 12V (ACC; yellow).

The CAN buses do not always work correctly. For one person it does work, for others it doesn't. It doesn't for me either.

A lot has been written about it also on the carjoying forum. I also wrote a "workaround howto". See here.

You mean the forum.carjoying.com site? I can access it from my phone, my work laptop, my personal laptop, e.g. from android, windows 7 and linux (galliumos). I never saw advertising?
[MTCD Android Head Units General] tuuza:
Yes, when I acces it from Finland, it redirects me to hundred looping advert sites. My pc browser refuses to connect due too many redirects.

Strange. We have/had Finnish users on the site as well.

Just to make sure, I checked my own link, but it is correct.

Anyway: I copied it to my google Drive into a

Word docx

I didn't care about the formatting. That is nicely done on the website.

I'm struggling with viper4android - I rooted the HU, confirmed rooted successfully, installed Viper4android latest version from their website, installed driver and rebooted but driver status always reports "processing: no". I tried locking the effect to headset, ensuring master power is on, but I can't get it to process. Tried removing & reinstalling driver but no joy.

Please can anyone help?
[MTCD Android Head Units General] tuuza:
Can you replace the stock EQ with viper? Tried it but vipers eq didnt seem to have much effect.

Ah a special version - thanks for that, I'll give it a try!

It's not really special, just a work-around to allow it to install it's drivers. Haven't heard complaints so I assume it works. Seems to work on mine. Let me know how it goes!

Do you know if the phone speaker tab is the only thing we can use? Saw a video of different unit bein controlled under headphones, no further info on that, maybe it was on RCA connections.

In the settings, you can "Lock Effect Mode" which will lock it to which ever tab you want.

Has anyone upgraded to the newest March firmware? Any thoughts? Is root access still available? Thanks!
[MTCD Android Head Units General] Flavio:
Root is possible.

Bluetooth is still shaky.

I had several Bluetooth share has dropped errors today out of the blue.
[MTCD Android Head Units General] gtxaspec:
GIVE ME please!!!! I will be your guinea pig! :) And from my testing, as long as the boot and system partitions are OK, overwriting /recovery with an invalid file will cause the unit to get a black screen for approx 10 boots (trying to boot from the invalid image), then it will boot normally. Also, if my local electronics store has a similar cable, I'll pick one up tomorrow and test!
[MTCD Android Head Units General] wanb1i:
There is no fastboot, only adb via wireless adb app. If we had fastboot you could just "boot" your twrp without over writing the stock recovery to test your twrp. Unfortunately, there appears to not be any access to fastboot on these systems. If you find a way to access fastboot, please let us know!

[MTCD Android Head Units General] AssassinsLament:
Is this from experience? It would be great if these devices were "unbrickable." The language difference makes it pretty difficult to find any info on these devices. So it would be great to know mistakes won't cost us $300+.
[MTCD Android Head Units General] Blaze Falconburger:
No joy I'm afraid :(

I removed the current installed version, then went with your method. I recreated all of the steps manually as I didn't have a laptop handy - but exactly the same. Viper installs it drivers, then still reports status as normal but processing as No. I made sure it was turned on, tried locking the effects to headphones, enabling some settings, but I just can't get it to process. I can't see what I'm doing wrong - I've installed Viper on many devices, all fairly standard once SuperSU & busybox are on

I'll give this a go next, thanks
[MTCD Android Head Units General] Andromeda_Station:
Should it not be 'speaker' instead of 'headset'? That's how my units have always worked (MTCB though).
[MTCD Android Head Units General] tuuza:
You can lock it to work on any mode you want. The headphone mode has alot more options.

Lähetetty minun E6853 laitteesta Tapatalkilla
[MTCD Android Head Units General] Blaze Falconburger:
Correct - I prefer it locked to headset for the extra adjustments, but also tried it on the default speaker option - which it recognises as when you open Viper it will auto select the output which is currently configured I believe, so by default it auto selected Speaker

I was using Poweramp as the source , which has worked fine on other Android devices but I'll try a different player just in case
[MTCD Android Head Units General] Andromeda_Station:
lol, I had no idea viper worked that way...I never tried anything other than 'speaker' on my car or 'headset' on my phone. :silly:
[MTCD Android Head Units General] Blaze Falconburger:
Well, what a numpty - in PowerAmp if I deselect use Directo Sound Control under Settings --> Audio, then Viper works! Schoolboy error, I totally forgot that one
[MTCD Android Head Units General] grumetecap:
Someone know how can we use the right side buttons from our steering wheels?
[MTCD Android Head Units General] wanb1i:
I have, the rom is fine and stable. Bluetooth to my phone and BT Music work great as does the BT connection to my ODBII device. After the rom is installed and the system reboots, you'll have to use the reset button, then the system reboots fine. That 2nd boot takes about 5 full minutes, so be patient.

I strongly recommend the latest edition of the sofia app mod that makes the unit remember exactly where it was when you turn off your car (even overnight). It can be found here:

https://xdaforums.com/android-auto/android-head-units/joying-2gb-steering-wheel-key-t3543390

Good luck! :cool:
[MTCD Android Head Units General] kampfschachtel:
perfect mod. I assume you have an Audi too:D

Is it maybe possible to make the frequency smaller but the radio station name / ST/ Genre bigger. this is somehow a big missmatch...

On a 10.1 screen that radio app ihas by far to huge numbers on the top half of the screen and the memory buttons on the bottom could be half size to fit doubled number of saved stations.
[MTCD Android Head Units General] tuuza:
Has anyone tested the Joying DAC for volkswagen units.

https://www.carjoying.com/joyingr-a...l-amplifier-fyt100-for-android-car-radio.html . I finally got my car running and on the road, wasnt too pleased with the sound quality. I have factory speakers and a model specific SW that gets signal from rear speakers. So it would be ideal to be able to direct the lows to rear speakers.

Also interesting that the unit has output power of 45w x 4, and the DAC has 30w x 4, does it really reduce the output power?

Lähetetty minun E6853 laitteesta Tapatalkilla
[MTCD Android Head Units General] WILD9:
The output from the head unit is 45 Watt Max and ~15W RMS I Think the 30 Watt rating for the Amp is likely to be the RMS rating which is a more meaningful figure anyway.
[MTCD Android Head Units General] gustden:
The only thing I did was edit the 'png' files and modified the color palette. I did play around with some of the XML files that define the UI, but that was much more involved than just changing colors. There are many things that could be enhanced here, such as the RDS text. Also the station Genre names are hard coded in the program, which is OK for Europe, but mostly wrong for the US.

Without having the original source code, it would be difficult to make more than cosmetic changes.
[MTCD Android Head Units General] kampfschachtel:
Thank you for explanation. Just want to have little cosmetics...is for changing the size of the tuner frequency not "just" a smaller font needed, same should be for the other text displayed (not the old school frequency band on top, that is actually somehow cool)

Yes a lot things could and must be enhanced as they are audio equipment manufacturers and not tablet producers.

So the basic is the overall sound quality and as android 5.1.1 should be USB sound out compatible, they should just deliver all sound out via USB or a TOSLink. 2nd Equalizer section with 3 bands, NOGO as standard are 15bands plus parametric equalizing. All just software to get it to the next level. Its a pitty as the unit is acutually very good for his price and downsides (beside the both above) can be fixed easily plus a 10.1 inch screen is awesome if you had a 6.2" Micky Mouse display before....

A analog Radio app can be worse as hardly used as DAB+ is the way to go.
[MTCD Android Head Units General] tuuza:
BTW, joying has changed the bodies of their new headunits to shorter ones.

[MTCD Android Head Units General] Sergio45:
I'm having a problem with the GPS signal.

When the unit comes to standbay for a short break in a route, the GPS signal is displayed in yellow, but can not connect to any satellite (green signal). After restarting the device the signal returns almost immediately and will not fail again until the next standbay.

I have put the last official update and I have modified the SOFIA-Server with the V3 of the forum so that it does not kill the applications.

Anyone have this problem?

Any solution?

PS: This is Not Gmaps issue since i look the GPS signal into the Joying App.
[MTCD Android Head Units General] wanb1i:
Have you checked the antenna connection is tight and the antenna has visability? You may want to check with Gustden to have him check the V3 app. I use Gmaps, have V3 and the March update and I don't have this problem.
[MTCD Android Head Units General] Sergio45:
I have the March update and the V3 from Gustden and i think the Antenna is good. Its a weird issue :(
[MTCD Android Head Units General] wanb1i:
Did it work before the update/app mod? Does Gmaps do this as well? What app are you experiencing this in? Try replacing the V3 sofia app with the original to see if it's that mod'd app? I had weird issues with the previous version of Gustden's sofia app that stopped when I restored it with the stock one. No dig on Gustden or his app mods, they're great, but sometimes odd things happen in these units. It's a simple test to eliminate a possible cause.
[MTCD Android Head Units General] Sergio45:
I will test it with the last update and without the sofia mod app. I really love the no kill feature tho.
[MTCD Android Head Units General] gtxaspec:
No issues with mod, typically its either a permission issue, or the user leaving double .apk's and they will interfere with each other. Using Maps/Waze here, works wonderfully.
[MTCD Android Head Units General] tuuza:
Is it normal Joying that I paid 30$ for fast DHL postage and they gave me tracking code.

But its been almost a week without the tracking code being registered to DHL tracking service.

[MTCD Android Head Units General] gustden:
I was having a similar issue with my phone, I would reboot and it would work fine. After that it would take a long time to get a lock, or never get a lock. I used a program called "GPS Test" to clear GPS data. ( 3 dots -> "Clear AGPS" )

After you clear the data, reboot and go back into "GPS Test" and (3 dots -> "Update AGPS") and leave it with direct access to the sky and powered on for ~15 minutes with the GPS active and connected to the internet. This gives it time fully download the GPS/aGPS data from the satellites and internet. It seemed to help quite a bit.

I know my Joying is generally pretty quick to lock and keep a GPS signal well. Much better than my phone.
[MTCD Android Head Units General] Sergio45:
Thanks, i will try the app and hope the gps gets better.

BTW: Thanks a lot for the no kill fix. Was pretty annoying open spotify every time i get on the car.
[MTCD Android Head Units General] dalu:
did you ask them about this tracking number? I have the same situation.
[MTCD Android Head Units General] tuuza:
They delivered it to DHL 4 days later, wich sucks..
[MTCD Android Head Units General] tuuza:
My situation is: I have the new digital amp from Joying, and I have a high-input subwoofer that passthru signal to front.

Now when the new amp is installed the subwoofers shuts down everytime headunit doesnt output sound. Causing a delay of couple seconds everytime sound starts.

I have a wakeup signal wire to the SW but it only takes effect when the RCA input is active.

Any idea how I could stop this from happening?

Lähetetty minun E6853 laitteesta Tapatalkilla
[MTCD Android Head Units General] bogdi1988:
Connect the wake up signal wire to a different source? Like pull from a speaker, or the ACC wire?
[MTCD Android Head Units General] tuuza:
My subwoofer has a wake up wire, but the problem is that german engineers decided that the wakeup signal works only when there is RCA input, I have speaker wire input. So the sub takes wakeup from speaker signal.
[MTCD Android Head Units General] naplesbill:
I would try to connect the amp wakeup to the radio power so that it is on whenever the radio is on.
[MTCD Android Head Units General] tuuza:
As I mentioned, the amp does listen to wakeup signal only when using RCA connection.

When I use speaker signal connection, it starts and stops when speaker wires give signal. Without the digital amp the subwoofer stays on when radio is on, even without wakeup wire.
[MTCD Android Head Units General] naplesbill:
When using the wakeup wire you disable the signal sensing on the amp.
[MTCD Android Head Units General] tuuza:
Unfortunetaly there is no option to do so :/ I came to a solution that i need to switch to rca signal.

Nice thing about the current setup that it also amplified front speakers to 50W RMS.

I quess that the joying does output rca and speakerwire at the same time?
[MTCD Android Head Units General] naplesbill:
Yes it does. The rca output can be turned off though

---------- Post added at 12:26 PM ---------- Previous post was at 12:25 PM ----------

I run a 5 channel external amp
[MTCD Android Head Units General] tuuza:
Ok thanks, I'll run the sub from rca signal. Overall the digital amp settings seems very good and usefull
[MTCD Android Head Units General] tuuza:
Hi, I changed my sub to run from RCA and other speakers with original wires and the new digital amp.

Now the sub doesnt react to volume knob, when I set volume to 1, speakers are quiet but sub is like at volume 15.

Could the digital amp cause that RCA output volume control is disabled.
[MTCD Android Head Units General] naplesbill:
Sounds like it may be possible. Did you run the sub out straight from the HU to the amp? Did you adjust the gains on your amp also?
[MTCD Android Head Units General] tuuza:
The cables runs straight to the sub from HU (front speaker outputs), its a ground zero active sub made for golf 6.

I have all levels around 50%, gain, phase, bass bosst is 1db.

When I set volume to 1 the bass is loud, but the bass volume stays the same when I raise the headunit volume.

Lähetetty minun E6853 laitteesta Tapatalkilla
[MTCD Android Head Units General] bogdi1988:
I think it might send the audio with max volume to the dac, and then that will be the one that adjusts the volume when the knob is pressed.
[MTCD Android Head Units General] naplesbill:
That is a terrible design if it's true. If true, they should have provided a sub out from the digital amp.
[MTCD Android Head Units General] tuuza:
Made a little video and sent it to Joying.

I hope they understand to fix it.

I'm having problems with my ELM 327 mini OBDII Scanner on my JY-UL128N2 ... I can get the bluetooth app to see and pair with it by setting the HU pin to 1234, but after pairing, it cannot communicate with my vehicle with any app. Torque, Commander, ect. Torque will see the adapter and connect to it and tell me there's no communication with the ECU. Commander won't even connect with the device. I know my OBDII port works because OBDII scanners are able to communicate with my ECU without any issues and I also had a Nationwide Smartride device in that port just before plugging this device in.. and it worked fine..

I tried putting the ELM327 device in first, then power on the unit, turn the car to the IGN ON position, and pair..after pairing, no communication to the ECU... no luck.

Is it possible my ELM327 is defective? Is there another compatible Bluetooth or USB OBD Scanner I can use?
[MTCD Android Head Units General] krasykp:
Hi there,

I want to ask about the Display quality of this Joying device.

Currently i have JY-VL130, but is very slow and I want to upgrade with JY-VL130N2.

I believe, with the Intel x3 and 2GB Ram, the problem with the speed will be fixed, but if the display is crapp ... maybe I will look for another brand.
[MTCD Android Head Units General] kampfschachtel:
If you have an androif phone put torque on an check if you can pair and connect to the phone. Sometimes it needs 2 till 3 attempts that the phone finds. Put OBD 2 scanner in, start engine and wait 3 minutes, only then pair it. Then start torque and see if connects. If you cannot pair it with the phone it is most probably defective.

With the joying bluetooth app every unit that is not called "OBD" is not able to be paired.

You need an app from the play store that is called "bluetooth auto-pair" from Michael Brachmann which costs 2$.

https://play.google.com/store/apps/details?id=com.brachcon.btautopair&hl=en

With that it worked. If have the "carly for VAG dongle" and it was possible to pair it with this app.
[MTCD Android Head Units General] frankienones:
I haven't noticed this setting. How do you get to that setting ?

(Turn off RCA output)
[MTCD Android Head Units General] naplesbill:
Go to carsettings app, then the sound tab. Amp switch is the setting.
[MTCD Android Head Units General] frankienones:
ok, i have seen this setting , and assumed it was for the control wire for external amp.. I had to check it , after reading this :confused:

This setting does enable output 12V on the control wire for external amp (orange/black)

The output from rca connectors will be untouched

(that is on my unit , an DE-JY-ULS02N2 )
[MTCD Android Head Units General] naplesbill:
I see what you are saying, but same difference in practice. I wish I could turn off the high level output
[MTCD Android Head Units General] tuuza:
Joying seems not to have any interest in fixing the problem in their digital amps, when plugged in it cripples all the rca outputs including sub out. Seems like it's just threwn together and not tested at all, with the stupidest coding job, as usually.

Anyone know if video input can be modified to have distance lines on the screen just like backup guide lines can be modified?

I installed a front camera but would like to add guidelines to it to make use of distance determination.
[MTCD Android Head Units General] bogdi1988:
You can buy a camera that automatically overlaps the guidelines in the video it sends to the head unit. My rear camera has that so I have to disable the Joying guidelines to not have duplicates.
[MTCD Android Head Units General] sonof:
But they are not measured distances and are rather useless on my opinion for that reason. Also, they don't tell anything about the width of the car which is very useful when using measured guidelines of my own (like I did with backup guidelines).

My camera also has the option to burn the guidelines to image by cutting an electric cord but I haven't done it for those reasons.

But thanks for the suggestion! :)
[MTCD Android Head Units General] simpl3lang:
I don't know about the 10.1 universal screen, but I bought the RAV4 2gb unit and while the screen is nice....at certain angle it's unviewable. On my RAV4 head unit the driver and front passenger can view video good. but since its tilted a little bit (upwards), the people in the back can't see the video good. Its not an ips screen so I guess it's expected. That's my major dislike of the unit. I'm currently browsing for a dual screen headrest monitors to connect to the joying unit so the people in the back can enjoy the videos being played.

I will try and make a video to show you.

If joying ever upgrade to using IPS screen I will definitely upgrade again.
