[MTCB Android Head Units General] Core-Lokt:
Hello, all. I recently got a JY-UQ128 and am starting the install/familiarization process. I want to mention that I am just slightly familiar with Android OS, so please bear with me if my questions seem rather fundamental. There's a couple things I need help with, and if there is anything y'all need to know, please ask.

Firstly, I seem to have issues while trying to browse online. Just going to Google spams me with certificate warnings, but it's like that everywhere.

Secondly, I haven't been able to get steering wheel controls recognized. My vehicle is pre-CANBUS, and from what I thought I understood, I would not need the PAC or Axxess converter. There's a PCI bus pin in the plug, and I asked if that connects with either/both Key 1/Key 2 wires. About all I got back was if the radio has one wire, you only need to connect either Key 1 or Key 2 and make sure the radio is grounded. Also, in the Factory Settings, there are some terms that *might* have a bearing in the matter, but IDK. Stuff like "wheel 3", "rudder (I guess that's steering wheel?), etc.

Thirdly, I started a Gmail account (kinda thought that was a global Google log-in) so I could access Google Play. It shows connectivity problems even as I can kinda browse websites. Can't get to Amazon App Store through my Amazon account on this head unit, either. I keep getting prompts to enter the cell number or e-mail. I enter the e-mail associated with my Amazon account and I get a prompt to reset my password. Nothing I have to log into recognizes this device.

If I could get a hand with these, I would appreciate it. I've started going over this thread and will try not to make a n00b pest of myself. Thanks in advance.

EDIT: I saw a post from "rickthecabbie" where he writes uncheck "wheel 3". I'll try that tomorrow and report back.
[MTCB Android Head Units General] RabbidHampster:
Make sure you have the flashed the most recent factory firmware for your device. I recently purchased a joying unit and had loads of trouble while I was bench testing it until I updated the firmware. Your problem most likely stems from out-of-date google services.
[MTCB Android Head Units General] Core-Lokt:
OK; I'll look into the firmware update. Thank you.
[MTCB Android Head Units General] peterek:
Same here.... and it seems like the settings app for Steering wheel controls is missing i latest firmware from dec 25th...
[MTCB Android Head Units General] Core-Lokt:
Well, I didn't have any luck with "Wheel 3"; in fact, it was already deselected. I am a little frustrated, so I didn't try the various option in the drop-down menus in the steering wheel control settings.

I also had no luck in getting to Google Play. I took some screenshots so you'll see what I see.

I really haven't altered any settings I think applicable to internet connectivity. If I close out all those certificate warnings, I can browse. And I set up my pre-existing e-mail address just fine on the head unit.

Meanwhile, Rambo (Joying) and I will try to sort-out the steering wheel controls. I will bring up the missing steering wheel control menu.

EDIT: I see I can't post picture, yet.

Well, one message reads "Unable to establish a reliable connection to the server. This could be a temporary problem or your Android device may not be provisioned for data services. If it continues, call Customer Care."

Another message reads "Can't safely connect to server. (com.android.org.bouncycastle.jce.exception.ExtCertPathValidatorException: Could not validate certificate:null"

The last one reads: "There are problems with the security certificates for this site"-that was trying to go to Google Play Store.

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

I finally got logged in to Gmail/Google Play Store. Apparently, this is a common problem. Seems like time/date were set to update via GPS. As I'm still vetting things, the head unit isn't installed. When I removed it, I did not hook up the GPS antenna.

wifi stopped working after mutiple flashes

hi everyone.

I need some help getting my WIFI to work again. After updating my MCU and a whole bunch of diffferent .img files my WIFI stopped working. It wont enable itself on boot or let me manually do it. What should i try doing to fix the problem?

thanks Anthony

After few hours of testing music apps, I managed to find an excelent app for landscape mode. Forget about poweramp. Try " jetAudio Plus "

In my opinion is the best music app.

Here you have it specially customised for our HUs (look some previous posts in that thread for different resolutions).

Malysk ROM has it built-in. I recommend to try it.
[MTCB Android Head Units General] florin1up:
How can I remove the volume bar without rooting the unit? I tried some apps but no luck without root.
[MTCB Android Head Units General] Core-Lokt:
Are you seeing pop-ups for in-app purchases in JA+? I saw a LOT of reviews where people were pissed about that.
[MTCB Android Head Units General] florin1up:
I bought the app yesterday, and no popups appeared .. so far..
[MTCB Android Head Units General] Core-Lokt:
Any 3G dongle recommendations? Thanks in advance.
[MTCB Android Head Units General] Jskash:
So I just purchased the JY-UQ124 with RK-3188. I'm super excited about it, but... I'm nowhere near as knowledgeable as the lot of you on here. I've swapped about 7-8 HU my entire life, but it's been a good 15 years since the last time I changed a HU in my car... so what I did know is from a long time ago.

I bought a Metra wiring harness to hook this thing up to my 2004 CRV and I'm only able to do it in bits and pieces because I have 3 small children and well... you don't get time anymore...

So with HU installed, I also ran one of the USB cables into the cubby I have just under the stereo. I haven't installed the drive camera as I'm going to call it, or the backup camera.

I haven't updated firmware yet. Haven't even checked to see if I needed it yet. Not sure if updated firmware is coming installed on them now. Anyway, everything that I have hooked up appears to be working fine until I turn on my headlights. Then it seems that the unit is trying to go to the backup camera and obviously there's no signal. Lights off, everything works just fine. I took a quick video of the problem and emailed Joying support, but thought I'd turn to you guys as well.

Also, the radio antenna doesn't pick up some stations that I had clear as day before. Has anyone had success with any kind of amplifier? I know they sell one for $10 off their website, but I have also seen a load of videos where these things are doing nothing. If anyone has one they've opened up and can recommend as a legit unit I'd gladly buy it.

And make sure you guys come back here a lot, I'm going to be asking a ton of questions over the next few weeks I'm sure.

---------- Post added at 10:04 PM ---------- Previous post was at 09:20 PM ----------

OK, well I just went ahead and updated the firmware. Not sure that was a good idea. It appears to have been from the same date. The previous firmware would have "Joying" in the bootup image. Now it says "Android" which I kinda like better.

But then I look at the rom and it seems before I had like 1.5 gb in the OS partition and now I only have 1 gb.

I had to reset the clock again, not sure if that is related to the firmware being reset or is it just going to continually reset back to HK time all the time, which is already driving me nuts.

I did find the feature to turn on the video player. It wouldn't let me play videos before, even while parked, but I got that sorted. What next?
[MTCB Android Head Units General] azuman:
Hi guys. Does anyone face issues with the bluetooth connection between the unit and the phone? I have a oneplus one and cant get it to connect. Just connects for a second then gone. Tried the bt settings thru factory settings, as well as enabling/disabling mtcbluetooth in xposed with no luck. Any help or ideas appreciated! Thanks guys!
[MTCB Android Head Units General] CARRisma:
I much prefer JetAudio. But sadly it keeps on crashing. I have a hunch its because of my large music collection - about 70-80 gb / 8000 tracks. So I reluctantly use PowerAmp instead.
[MTCB Android Head Units General] RichyE:
I use the unit daily with my Samsung Galaxy Grand Duos I9082 (Cm12 and now CM13) without a problem.

I did a have a problem when I tried the new fusion rom from Boondock, but after a factory reset and first setup bluetooth and then the rest it work also on that rom
[MTCB Android Head Units General] RunNgun42:
I had same problem. Steering wheel controls were recognized by HU, however only volume worked, could not skip tracks in spotify.

---------- Post added at 11:46 PM ---------- Previous post was at 10:54 PM ----------

I believe the certificate errors are a bug that require you to clear the cache on the various Google Play services and Framework options. There's a guide somewhere online about this, pretty sure I had the same problem.
[MTCB Android Head Units General] Core-Lokt:
Damn; I thought I had posted I found the solution. It was the clock.

Since I was doing a number of things at the same time, I would occasionally have to unplug the HU. And when you do, in these radios, the time reverts to 00:00. Even if it's uncommon, it seems like it's a known problem, as I found it by searching for the specific error messages.

Years ago, I had a Samsung Captivate running Eclair. Between Samsung and AT&T, I swore off Android. Had that been a good experience, I probably would be up with everybody else on knowledge/abilities. As long as this HU behaves, I'll get back to speed and maybe Android for a phone. Thanks, all.

I have you tried playing around with MTC-keys?
[MTCB Android Head Units General] t_waran:
I am also having the same issue (having One Plus One - rooted/running cm13 nightly). But able to play music from my phone to the unit. When I tried my wife phone (which is also One Plus One with Cyanogen OS) it worked great. Not sure what can be the reason with my phone though. Let me know if you find a solution for this. Thanks!
[MTCB Android Head Units General] azuman:
Well, so far the only thing that works for me is to revert back to android 5.1.1 and then bluetooth works perfectly. With cm13, it doesn't connect at all, so cant play music or receive calls thru the unit :(
[MTCB Android Head Units General] vlaine:
JetAudio won't stop radio by itself. Is it normal ?

Steps:

1. Start radio

2. Start JetAudio and select a song

Observed behaviour:

The radio is still playing. JetAudio progress bar is progressing, but I can't hear the song playing.

Workaround:

Manually close the radio app. Then go back to JetAudio, stop and start the song again.

There must be a better way.

Note, I didn't purchase JetAudio Plus yet because of this issue. I have the free JetAudio app.
[MTCB Android Head Units General] carter.w.jason:
Yes, this is normal for any non stock music player. You can use Tasker as a workaround.

Set up a profile for JetAudio and then add this task to the profile

Task > Code > Run Shell

In the "Command" field type am broadcast -a com.microntek.finish --es class com.microntek.radio

Use the "use root" option

That's it!

Let me know if you need more help, just woke up and need my coffee.
[MTCB Android Head Units General] vlaine:
Thanks for the quick reply.

I will try it today.
[MTCB Android Head Units General] vlaine:
I was not able to close the radio when opening JetAudio plus using tasker.

Instructions were very clear. I wonder what I missed

-- Edit--

I have to root. It's not working because I'm not rooted.
[MTCB Android Head Units General] Core-Lokt:
Any luck? I've learned to use one or the other and would like for JA to close without manually exiting.
[MTCB Android Head Units General] vlaine:
I want to order a bluetooth OBD. Joying sells it for $20 while I found many for less than $4 on aliexpress like the one below. What's the catch? Will the $4 one work?

Is there a list of compatible devices I can check somewhere?

[MTCB Android Head Units General] Taomyn:
It's been my experience with cheap BT OBD2 adapters that you get what you pay for. From unstable BT connections, to very poor performance (so if you want accurate information for say showing RPM as a dial) and most importantly most of these cheap units have no sleep mechanism. If you're going to simply plug in, check the un-plug then the cheap ones are ok.

However, the OBD2 port is live all the time even when you switch the ignition off and take out the key, and the cheap adapters stay enabled and running all the time they remain plugged in - wait a few days and you'll have a flat battery. In the end I shelled out more money on a proper adapter and got a Scantool.net OBDLink LX, but there are many others out there that work just as well.
[MTCB Android Head Units General] vlaine:
You took the bluetooth or Wifi?

It's compatible with joying head units?
[MTCB Android Head Units General] Taomyn:
I have the bluetooth version, but I cannot say if it will work the joying units as I don't yet have one - I am waiting for the next generation of their units to be released and then it will replace my ageing Parrot Smart Asteroid. I lurk on this forum thread to keep up-to-date.

I cannot see any reason that it would not work as I've paired it to numerous phones/laptops as well as my Parrot without a single issue.
[MTCB Android Head Units General] driedger:
I'm a lurker here as well, but just got a joying unit a couple weeks ago. The joying unit will only let you add an obd2 adapter that has a device name of OBD...

Mine is a Chinese knock off I bought 4 or 5 years ago and comes up as CBT when searching. I was unable to pair my adapter with the joying unit until I enable led root and installed the xposed framework with the xposedMTC extension to change the device name it looks for.

It's a little bizarre, I've never seen any android device that you could only pair specific device types.

Regarding the adapter, I had problems with it in my Chev Impala with corrupt packets and slow sample rated. It seems more reliable with my wife's crv and my new accord though, but the sample rates are still much slower than if you used a branded device like the scantool. Mine works great for reading codes and using for instant mileage but it doesn't read the pids past enough to E good for realtime info on rpm, speed, 0-60, etc.
[MTCB Android Head Units General] mike.s:
That's because Android doesn't have direct control of the Bluetooth in these units. Same with WiFi. For both, the MCU sits between Android and the hardware, so there are limitations associated with that.
[MTCB Android Head Units General] Core-Lokt:
I got one of the cheap translucent blue ones off Amazon. It pairs with the Joying HU and seems to be recognized by Torque Pro. However, Torque Pro can't see the ECU.

Looking at the adapter, it's 16 pins for the port, but only five at the bottom right of the trapezoid and three on the top right of the trapezoid go into the board, so there's eight dummy pin-outs. IDK anything about OBD II, but I would've thought more (if not all) pins would be required.
[MTCB Android Head Units General] NP08:
What year/make is your vehicle? I have a 90's model GM car that used a 1-year only 16 pin OBD-2 shaped connector, but it is an OBD-1 system. My OBD system uses one wire for serial data and one for ground, so only 2 pins are utilized for data transfer, and as I recall there are only like 3 other wires mainly power & ground or for keyless remote programming. Later model vehicles use more pins for various data transfers.
[MTCB Android Head Units General] Core-Lokt:
2005 Dodge Ram-last MY before CANBUS. It seems there's more information out on GM and Ford vehicles than ChryCo, so IDK what pin-outs are used. From looking over at Cummins forums, I think most use the ScanTool LX, so maybe I ought to try one.
[MTCB Android Head Units General] jakejm79:
Has anyone tried a hardwired USB OBDII dongle?
[MTCB Android Head Units General] ehode:
Maybe pointed out but couldn't you add a USB Bluetooth dongle and pair the OBDII device with that? Since that would be android direct vs the hardware layers, I believe referred to as the MCU?
[MTCB Android Head Units General] jakejm79:
I already have a USB OBDII dongle that I have been running with Ouku headunit and data transfer/latency is a lot less with USB.
[MTCB Android Head Units General] robjg:
Can anyone confirm if the Easy Connect app will still work after rooting? I really want to install the viper4android drivers, but I read on the Joying blog that root could disable Easy Connect.

Also, is there any way to fix or remove the Weather widget? I can't get it to display any weather, so it's basically just a waste of space on my home page.
[MTCB Android Head Units General] jakejm79:
So got it all installed and everything just about works.

USB OBDII adapter works with the included Torque Pro, my existing backup camera worked.

I do have a couple of issues:

1. I see there is no long a radio widget, in order to get radio info on the homescreen I need to use the stock launcher with the combo radio/weather widget built in. Are there any other radio apps out there that have widgets. I despise the stock launcher but don't really want to give up having the radio frequency visible from the home screen.

2. I'm having in issue with steering wheel controls and it controlling multiple apps at the same time, basically if I have pandora playing and hit the pause/play button, pandora pauses but another music app starts (I downloaded an AOSP music player from the play store). I somewhat remember having this issue on my Ouku unit, but I'm not sure if a different music player fixed it or not, anyone else have an issue like this.

You don't need to use Tasker. Just setup JA as your default music player then use the play music shortcut. works fine. However I will say that JA often fails to restart for me. Works about 75% of the time. I suspect it has to do with trying to start up before the SD cards are mounted but I'm not 100% sure.
[MTCB Android Head Units General] Roerbakeitje:
Hey all.

I have also a joying device. And i.m pretty happy with it. But as almost all android jusers the whant to make it yours.

First of all i have the rk3600 version and have succes Root the device. And set some tasks with tasker and auto input. But there is a problem with this device and i dont know the anwser. When you go to settings and tap accesseble you will see that it is not complete. Als the development options are gone. Also when you tap 7 time on the bild number.

I think it is blocked and not fully removed.

And now my question I need the accessibility function ore the development option to run auto input correct.

Is there a solution?

[MTCB Android Head Units General] talroot:
Anyone ever figure out why the clock format changes from 12 hour to 24 hour occasionally after a reboot? I'm using stock rom and have this issue from time-to-time. I also have an issue where iGo configuration is lost and I have to walk through the setup again after a reboot. I've also lost my preset radio stations after a reboot. What seems to do these things every time is going into factory settings and making a change (irrelevant to any of the above) then it prompts to reboot and voila, settings are lost. I'm back and forth with Joying trying to figure it out but it looks like the conversation is coming to a close with them asking me what settings I've changed and how did I manually reboot the unit. It's done this since new so I don't think there's any settings I've made to cause this behavior. To me it seems like something is not getting cleanly unmounted or permission issues prior to the unit shutting off.
[MTCB Android Head Units General] SurferJon:
^ I came here to post the exact same thing. It sometimes saves the setting, but it eventually reverts back to using 24 hours and unchecking the option. I was going to use Tasker + Autoinput to save the setting, but Autoinput won't show up in the Accessibility settings for me to enable it. Sucks. The unit draws some power from the car battery when fully powered off, so you would think it would save the settings like the tiny batteries in computers that keep the time. Next option might be to find a clock widget that displays in 12 hour format.

I lose my radio stations all the time.

The hard drive says it's out of space when I try to install apps even though there's barely anything filling the unit.

The unit never connects to the Internet via USB because of some problem with Kitkat, and you can't set Tasker or Autoinput to turn Wi-Fi tethering on your phone on and off, so I have to manually turn on the Internet every time I enter the car.

But I like this Joying unit.
