yep - GPS antenna, and external mic. My theory is that it is something to do with how the vehicle "enables" itself to allow the remote key lock/unlock. For example, if you are in the car with the accessories on, the remote key lock/unlock is normally disabled. When the unit is in "standby", it must be drawing enough current that the vehicle doesn't switch over to allowing lock/unlock remotes.

I wonder if it is a current thing? Will do some more testing.... Thanks for the reply. PS - the reason i did not find out straight away is that the previous Android version did not have the option to extend the "power down" time. So when i upgraded and then set it for 2 hours, it must have taken a while for the first "fail" to happen (ie coming back to the vehicle sooner than 2 hours), which i blamed on the remote battery...
[Android General] JEMShoe:
This is an interesting observation. I have come to my car a few times in the last couple of weeks and grabbed the door handle and the door did not unlock immediately...I had wondered why. However, when I let the door handle go then regrabbed it then it unlocked so I did not make a big issue out of it. I too thought it might be time to change the battery. But now that you have posted this, it kinda makes sense and I now want to do some tests to see if this is the cause.

I am an E/E Engineer; I had a similar issue with a remote starter and I devised a way to deal with a similar proximity detection issue that was caused by it (but in hindsight perhaps the vehicle's 'accessory convenience delay feature' was the true cause). If the radio standby feature is the problem I will investigate and identify a fix.
[Android General] pwb001:
excellent, thanks. I am a lawyer, so i am much less likely to be able to identify a fix! I am absolutely certain though it is the standby feature. Unlock/lock works fine when either waiting for the standby time to run out OR turning the unit off before turning the car off. Happy to contribute other diagnoses or tests if that helps.

PS - one other solution i am thinking of is to go back to version 4.2. Trouble is, i can't remember what screen resolution i have (or where to find it) to work out which version to reinstall. Not confident enough to guess, and then undo something that doesnt work. Do you know where to find the screen resolution, or is there something obvious?
[Android General] rushtoshankar:
Hey, JEMShoe, can you please let us know if you find any fix for this issue. In the mean time i will also try to do some analysis as far as I can.

Thanks.
[Android General] JEMShoe:
I don't believe it is current, otherwise the remote lock/unlock or proximity would not work if you left a dome light or headlight on (which draws more current). The JYHU standby draws about 500mA (on my bench). But if the radio is connected/backfeeding to some other part of the vehicle's 'accessory convenience delay feature' then *maybe* it is somehow not allowing the vehicle to reset and await a proximity event.

If that were somehow the case, I don't think the radio can reset the vehicle directly. If I knew that that was indeed the case, I would install a device that monitored the current flow from the radio after loss of ignition, wait for ACC delay mode to drop out (i.e. transition from 500mA down to 10-30mA--no_longer_in_standby) then activate an external device to drive the vehicle reset mechanism. A lot of not-so-specific tech lingo but the point being that a method to monitor the radio's state then externally trigger the vehicle (reset the proximity detection to waiting for unlock event) most likely has to be established. If you have a FOB issue where pushing the Lock or Unlock button no longer works then that is very different issue; my remote only does that if a FOB is already in the vehicle (also prevents someone from just walking up to my car while I'm in it and unlocking my door by pulling a handle).
[Android General] Dvalin21:
Been watching these radios, plan to get one myself. I hate the fact it uses RK CPU though
[Android General] pwb001:
thanks again - i don't really want to waste your time. It is definitely a FOB issue though. While the unit is in standby (ie 30 seconds to 2 hours, whatever user setting is chosen), the key fob will not lock/unlock the vehicle *unless* held right next to the antenna/receiver in rear window pillar. That's what made Toyota think the receiver/antenna were the problem, at $350+ cost to me.

However, as soon as "delay" time expires and the unit truly turns off, the key fob works as per normal. The verification of this i have done is to either:

- set it to 30 seconds, then wait 30 seconds and the key works fine, OR

- physically turn the unit off before stopping ignition - key then also works fine.

I still think that the car detects something from the unit while in standby, and then prevents the fob activating lock/unlock. the same way it does when the fob is in the vehicle itself.

(This vehicle you can't leave the headlights on when getting out of the vehicle. You can leave a dome light on, but that is not on the "accessories" circuit and can be on/off anytime. ).

Anyway, i think i am out of my depth in any complicated android solution or any wiring solution for the Aurion, but i do enjoy the "problem solving" aspect of it all!!

Root easy way and GPS Mixing problem ...

First of all, sorry for my english from video (and for how I write :D )

A simple way (found it on this forum) is posted here: h t t p :// www .youtube.com/ watch?v=wkfs856DQyg

For "Bad Radio signal reception" solve problem you can acces THIS LINK h t t p :// goo.gl/ photos/YdDScrApBrbd786w8

Personally, I have a problem with GPS Mixing function: h t t p :// goo.gl/ photos/5Fca6ywa15k2piYP6

which is not working... (this video is made for Joying team to show them that this function is not working even if I made some things that they told me to do...) The last thing they told me to do was to made a firmware reinstall, which I made it, but not solving my problem... Any ideas?

Thanks :)

PS: I have to put some spacing in links because I have no rights to put links, right now :)
[Android General] Dvalin21:
It's a pain working with RK, but the best people that I've seen making major head way with it are over at freaktab.com. you might want to check there for solutions as well
[Android General] valimaties:
Ok, thanks. I will start a thread in that forum too... :)
[Android General] Dvalin21:
When you post over there let me know me know. Like I said I plan on getting one of these or similar myself
[Android General] valimaties:
I post today a new thread on that forum!
[Android General] valimaties:
I found another bug, on radio application. It does not save the name of radio station for always. The RDS function retrieve the station name and other information (sometimes it is a long text - 64 characters, according to RT <Radio Text> information from RDS data) and I think it truncates this text in wrong position.

The PI (Programme identification) information from RDS data, for Europe it's not the same like USA PI information. According to wiki RDS's page, PI information is retrieved using a formula from Call Sign (we don't know this formula, and I read on other forums there is no formula !!!)

Ok, to came back to this problem I have attached three photos.

First one is after a search procedure, or after I press a favorite button, or after a period of time (it changes the text of button according to the orange text in the center of the screen,

not a good ideea

). If the text on the favorite shows the name and you press on it, it will change to frequency :eek:

The second one is like should be, the name of the station, the good name, and it is saved also to favorite button. After it is saved in good condition to favorite it should not have to change anymore., but it's changing.

The third one is after some cycles of changing from frequency to real name. It compose the text from part of frequency and name. This is not good at all!!!

So, the answer from Joying was "I will forward to Joying engineers your problem...". And now I will wait... for how long I don't know...
[Android General] robertbaruch:
Does anyone know if I can add a boot passcode? Because if I add my Google account to the device so I can access my gmail, chrome bookmarks, map favorites, and so on, without a secure boot, anyone can steal the radio, power it up, and access all my stuff with zero effort.

When I asked Joying, they said to install any lock screen app from the Play store, but I don't need a lock screen, I need a boot passcode.

Would rooting help?
[Android General] JEMShoe:
Joying headunits have a crippled Settings app that does not allow Services to be utilized under Settings->Accessibility. As near as I can tell this will render all Play Store security apps unable to secure at the boot or device boot level as they all ask for Accessiblity/Services settings. I have successfully tested these same apps on my Nexus 7; difference is no crippled Settings app. I have asked Joying numerous times either to uncripple it (no answer or even acknowledgement of the message) or for someone on XDA to assist in restoring that Android standard capability (I modified an *.xml file to get the category to show up but haven't figured out the app access block yet). Until then, the easiest way to secure your radio is to install a hidden toggle switch inline with the ACC wire to your radio. When taking it in for service, turn the switch off. As far as someone stealing your radio, that would require a boot level app or cellular service to do a remote wipe (via Find my Android).

FYI, For this simple reason, I do not use mail, contacts, banking apps, or any apps that hold valuable information on my car radio. I still regard it as

a car radio

; my phone is more secure (its hardware, software and services).
[Android General] Dvalin21:
Is it possible to remove the crippling app? Or does it still not release the Acc settings.
[Android General] JEMShoe:
It is a native app (like MTCRadio, MTCMusic, etc). It was written specifically for this device (so an Android phone or tablet's Settings.apk will not work as is). The only choice is for us or the ROM programmers to repair/replace (uncripple) it.
[Android General] Dvalin21:
That is crap. Maybe Reporting it as a security threat they will see the error of their ways. Their main site is carjoying.com maybe their is a subforum for the site. If you go to the site and start posting your findings other will start complaining as well. They will be forced to do something about it. I like the idea of a boot passcode. Even a lockscreen can be by passed if the device is rooted.
[Android General] JEMShoe:
Settings->Accessibility->Services is not just good for a bootlock or screen lock; there are many, many, many different apps on Play store that make Android devices safer and easier to use for those that have disabilities (or from my other post..."limited mobility. In truth, when driving in a car we all have limited mobility in that some activities jeopardize safety.") and can improve usability for everyone.

Android, Apple iOS and Microsoft all have Accessibility settings. Apple boosts that it makes its devices work for people with challenges without looking for financial ROI. Apps like Tasker and various plugins use Services under the Accessibility menu--but it will not work on the Joying units due to the crippled Settings app. Certain kinds of automations will not work. Many things that could be improved by not requiring the driver to touch the screen so much while DRIVING require Accessibility menu. When driving I do not want to have to touch my screen to hear the next podcast but on Joying the next/prev steering buttons only work with their native apps (most likely to MTC tie-in...I verified that an external keyboard with multi-media buttons can control non-native apps).

Edit: I just want to publicly correct this statement as I determined that some non-native apps do work with the steering wheel's Prev/Next buttons. But not all...

As an example, I can make my Nexus NOT require an access code when used on my own WiFi network or at my GPS location but make it required elsewhere. Can't do that on Joying. I could make the Nexus turn on my driveway lights if it is a certain time of day and I am at the GPS location. Or signal to the spouse that you are near. Or automate configurable system wide Inverted Colors (day/night modes). I can act on various Notifications from other apps. But not with crippleware.

When we get crippled Settings, we lose some of the power of having a smart vehicle via the Android-powered headunit. Downloading apps that need this setting is a pointless suggestion from Joying. I sent them (Rambo, Chelsea) this email several times and contacted one reseller, no responses yet. Settings.apk is an app that can probably be fixed very easily by Joying since it is a subset of the full apk released by Google KitKat.

All we get is "Be trust is joying." at the bottom of the screen.
[Android General] Dvalin21:
I do hope they fix this. One I plan on getting one of these and two, I want to either design a launcher or android based os that would mimic "Kit" from Knight Rider series

---------- Post added at 06:54 PM ---------- Previous post was at 06:48 PM ----------

Seen a nice tut on xda on how to design a launcher. I'm think it would be easier to do the launcher than the os.

ok so i got myself a Joying JY UQ128 buttonless headunit

its 16GB nand flash and ddr3 1GB ram

problem is only 1gb is allow for downloading of apps

the rest of the 16gb left untouch.

i also have sd card 32gb, but i cannot install apps on sd

im rooted via *#hct#root# and install link2sd.

im still not seeing the 16gb being utilised.

any guru have an answer to my question. i want to be able to install more apps on the 16GB storage.
[Android General] Dvalin21:
Did you try kitkat fix app?
[Android General] kelvinchewsg:
Nope no idea what is kitkat fix ... Can elaborate
[Android General] Dvalin21:
It should allow access to your external sdcard for all apps on your device
[Android General] NemeGuero:
Hi All,

just got the JY UQ124 and I love it.

Just curious if anyone knows how to auto-hide the notification bar up top?

I'm rooted using the *#hct#root command and have installed the KLD launcher.

Does anyone know how to add apps to the KLD quick launch or change the widgets on the main screen?

thanks.
[Android General] ozzy lion:
Hi, I have a similar unit but the LCD has developed an issue. The colours are all inverted a bit like film negatives.

Any ideas before I remove it and try to RMA it?
[Android General] Dvalin21:
Haven't dealt with that before
[Android General] talalalal:
Would also like to know if someone could please share any insight.
[Android General] NemeGuero:
Unfortunately I haven't found a solution I'm happy with either. The widgets are built in to the launcher and most people don't mess with stock launchers.

You can hide the notification bar with Next Launcher but I don't like it's interface.

I've tried xposed modules- Wanam and GravityBox -None of them had controls to hide the notification panel.
[Android General] NemeGuero:
Immerse

Immerse Xposed module gets rid of the notification bar in all apps.

Works great.

2015 NIssan Sentra CANBUS question

Hi guys! Please pardon my ignorance on this topic! I really want to buy this unit but the seller (Joying) asks me if my car has CANBUS. Is this related tot he harness? I have searched the internet for 3 days and I cannot find the answer. I read that all cars past 2008 have it. On youtube there is someone who installed an Ouku android head unit on a 2013 Nissan Sentra (youtube.com/bN0Zzz6l-kY) are they all the same? I am so confused. Does anyone have a late model Nissan that can verify if they have installed one of these units. Can anyone help?

Thank you so much!!!

[Android General] talalalal:
Hi All,

Does anyone else have problems with microphone call quality?

On my unit there is a severe buzzing for the person on the other end of the call.

- This is worse with the external mic but also bad when using the internal mic.

- The buzzing is worst at the start of a call, but improves a bit after a few seconds.

- The buzzing gets much worse when the car is moving.

Any clues on how to fix this would be greatly appreciated as the headunit is useless for calls right now.
[Android General] yellaboyla:
Sounds like a bad ground to your head unit. Did you use the ground from the harness or did you run it to the body?? Do you have an amp hooked up? stock or aftermarket
[Android General] Dvalin21:
Hey do we have a Carjoying rep here at XDA? I have a lot of questions I need answered by them before I make my purchase
[Android General] talalalal:
Thanks v much for the reply. It does sound like that. I used the ground from the harness with speakers also connected via the harness. No additional amp so far as I know unless one was hooked up to the harness as stock (VW Scirocco 2010).

I previously had a different android headunit hooked up via the same harness and the external mic worked fine (though nothing else did!).

Is there a better way to run a ground to the body?
[Android General] yellaboyla:
Might be a bad solder joint in the head unit itself, then. Do you here any feedback with the radio or playing mp3's??

Tasker’s Audio Actions

Hi all,

I’m trying to use Tasker to adjust the head units volume based on the speed of my vehicle. The issue I have is Tasker’s Audio Actions don’t recognise the head units’ volume control method. Does anyone know a workaround? I have also tried other apps to control the volume with no success.

Cheers Andrew
[Android General] talalalal:
No feedback with the radio or mp3s, just the mic when on a call, or for audio recording (used as a test).

It's pretty much ok when engine is off. When idling it's ok, a bit worse. When revving worse but still can be ok. When driving it gets really bad.

Also noticed that it gets worse when speaking loudly or with voice fluctuations. Could background noise cancelling be the issue?
[Android General] yellaboyla:
If you dont have an amp, it has to be a bad ground by what you you are describing. Try grounding to the car chasis. If you have an amp, then ground the rca jacks on back of deck.
[Android General] talalalal:
Thanks! For now I've resorted to using an app called SoundAbout that has a setting to use the phone's mic whilst maintaining audio output over bluetooth. It seems to be working.

Will definitely ground the head unit when I get a chance and report.

Hello,

I cant get this camera to work with my device, it says it supports Android 4.0 USB 2.0 OTG and UVC and above compatible, I have tried it with camerafi and other usb camera apps but the only app it works with is the standard dvr app that is pre installed with this unit but that only records in 640*480 resolution.. My player has RK3188 1.6ghz quad with 1gb ram.

I also wonder if bluetooth usb dongle support will be developed in the future, I need it to manage my dab box.. I am willing to donate some money for getting this to work.

Thanks to you all great guys here at xda forums.

Much Appriciated

[Android General] cev93:
I just installed this unit and was able to get the radio to recognize everything successfully.

However it is stuck in the wrong region, the radio believe its in China and thus there are some applications that I cant download. I also cannot download Sygic US maps.

I went to the settings and changed the time zones etc but to no avail.

Also I got the steering wheels controls working but they do not work on Google Music or spotify. They work fine on the built in applications.

Thanks.

Why are you in need of a custom recovery? What rom are you attempting to flash?? I have flashed both a new MCU and a custom rom and both were zip files.

I have flashed an mcu and a custom ROM as well. Both were able to be flashed via the stock recovery. What have you flashed besides the mcu and custom ROM? As far as what I want to flash and tinker with it could be anything. Maybe flash some audio Mods.
[Android General] NemeGuero:
Are we required to open the unit and solder the mic wire leads directly to the PCB on these units or have they fixed it with these generations?

Install one of them (accordingly to your chip) and you won't even have to play with Tasker to do that.

Hi, I just buy Joying head unit, 7'', it's still on android 4.4...

but for now, I don't mind that...

I have read that radio reception is not so good so I buy a antenna amplifier, and have one question, how to connect it ;

can I connect radio amplifier power supply wire (red one) to the head unit (blue wire) on which is written '' ANT.CONT (12V/500mA) ?

this ''blue wire'' is coming from HU

on radio amplifier it state that the ''red wire'' should be connected to the car key wire (ACC),

but for me it would be much easier to connect it to the HU blue wire, if it really have 12V on it...
[Android General] nu!me!:
I have connect ''red wire'' (ACC) from radio amplifier to the ''blue wire'' (ANT.CONT) on HU, it works :)
