Could this be the cause of my problem that the DAB+ radio switches off the sound after 5-15 minutes in the background? I have installed some of these System info apps, and they all show for the RAM: Max 1947 MB, Free around 730 MB, CPU Load somewhere in between 30 and 70%.

While playing around with this I found the core-temperatures. Is it normal that they are at 80-85 °C. Seems a little high to me.

Somewhere I read that these devices don't have giroscope, orientation sensor, linear sensor and so on, but these system info apps show me these sensors are there (but the values are allways 0). Are these there but not active? Can they be activated? Soldering on the sensor and it will work? Or are there other solutions to add a giroscope, over usb for example? Would be nice to have such apps schowing the tilt and pan of the vehicle working (the device will be built into an RV who is also sometimes driven offroad).

On my phone I can move less often needed apps to the SD card. That button is missed in the app-info display on the joying. Is it possible to ad this functionallity somehow?

Do you maybe have a heated windshield or one with some kind of anti-heat-coating. These can dramatically shield the GPS-signal. For a simple test you could just put the cable thru the side window and stick the GPS-antena on the roof.

Nice to see other Silverado drivers here. I also bought the new 10.1 Joying for my 2011 Silverado 3500. What MY is yours? Why hundred different adapters? I ordered the PAC RP5-GM31, soldered it together with the Joying harness, plug it into the car and as far I coud test it yet it works just great (right now it is to cold in the car so I have the radio plugged in at home on the desk without PAC and steering wheel). I experienced only 4 "problems" related to the PAC yet:

1. On the first try, I had to turn the volume up to near the max to be able to hear something.

Solution: On the PAC there are two sockets for the speaker harness (from PAC to the car harness). First I had the wrong one (preamp outputs) connected. Plugged the harness in to the other plug and it works great.

2. Most keys on the steering wheel produce a constant signal to the radio while holding them down. These are prety easy to learn. But two keys did only send a short pulse. I needed to push (at nearly the same time) both, the steering whel button and the one to be programmed on the Joying. That took 10-15 attempts to get them pushed at the same time and have them programmed but after that it works just fine.

3. On the steering wheel, the arrow key pointing to the right and the one with the arrow up produce the same signal to the radio, so only one of this can be used. No solution for that yet. I may try another configuration on the PAC, but I can live with that.

4. The chimes sound awfull (especially for the indicators, but also the other ones are not that great). That is a small device (probably a cheap piezo-speaker) with two cables on it, doing some noise. I need to mesure what signal is on these 2 cables, but I think that should be fairly simple to do some tweaks on that. But as for now it does the job, somehow ;)

5? I got 6: Source, volume up, volume down, mute, seek+ and seek-. But I think the Seek+ and - have allready some long push functionallity (tested with the radio app), so I actually have 8 functions as well. That all without programm the PAC for different long and short pushes, but with working OnStar and XM-Radio. If I want to take advantage of the long pushes I may lose Onstar and XM, but because I live in Europe I may get rid of these 2 functions, here they don't work anyway. Right now I'm not missing any functions on the steering wheel, but this can change while using it.

Where did you mount your GPS antenna?

Unfortunately I can't see your attached pics...
[MTCD Android Head Units General] concept5400:
I have already mentioned this problem in the middle of my Joying review in C500vsJoying thread but I am afraid that experienced Joying user's won't be checking there.

As this is my first Android head unit ever I am not sure if it's Joying only or general problem of those chinese units.

The unit can play radio sound AND sound of ONE other app with radio in the background.

This function is called GPS MIX and it's working only with predeclared NAVI app only.

If I declare Google Maps as my NAVI app - it can play radio in the background with Google Maps on my main screen.

But other NAVI apps in the background cannot produce sound.

If I would put other NAVI app on my main screen it wil start to produce sound but the radio will be turned off the second other app starts to do so.

Therefore I am not able to use two NAVI apps and radio at the same time.

In my country we have a Waze-like app for speed camera and mobile speed control units with a HUGE community and it's working like a charm (YANOSIK app).

The problem is that the app really sucks at turn-by-turn navigation. Everyone is just using it in the background with other NAVI app on main screen.

With this unit when YANOSIK (speed cameras app) is working in the background it will not produce any sound, unless declared as the NAVI app in CarMediaSettings. When it's declared as the NAVI app it will produce sound in the background but other NAVI app (like GOOGLE MAPS) will mute/turn off the radio completely.

I am quite desperate with this problem as for now I still have to use my phone for one of those app...

It's a 2008 1500 LTZ. I'm using the PAC OS-5 which requires an additional steering wheel adapter. I already had the ASWC-1 from a previous Chevrolet vehicle. I really didn't want to buy another expensive adapter just to get the steering wheel buttons to work. There was considerable lag sometimes with the ASWC-1 and sometimes it wouldn't work at all. Two of my buttons also send the same signal. I can't remember which ones but that's why I said 5 instead of 6. It was enough frustration for me to buy the cheap steering wheel remote. It may be a little bit of an eyesore but I don't mind and it works perfectly. My GPS antennae is under the dash panel to the right of the light sensor. That's where the stock GPS antennae was.

You should be able to see the images now. I don't know what's going on with the attachments.
[MTCD Android Head Units General] Pinkpanther9:
I consulted the schematics for the Silverados. They have a network with resistors and then with every single switch a different resistance is send to the body control module. Unfortunately, unlike other cars, and needed for the Joying radio, GM deceided to switch 12V, not a ground. And they connect these 12V into the harness in the steering wheel to the radio control switches and to the cruise control switches. You could disconnect the pink (12V) wire from the radio controls and connect a gnd there, then find the L-GN wire on the BCM, disconnect it there and connect the one comming from the steering wheel to one of the radio steering wheel inputs. I think that should work, but of course you would loose the Onstar, XM and Bluetooth controls over the steering wheel.

Thanks for that. I allways thought the shark fin on the roof would also be for gps, if equipped.

I need to check if I have room there...I have the slightly different dashboard (LT, single cab), but up there I thing they should be similar.

I have the same Problem like you. Did you find a Solution for this behavior?
[MTCD Android Head Units General] gustden:
Thank you for the information! I was able to modify the grid lines to match the backup camera to the path of my car . It took me a few attempts, but very happy with the results. I posted the d1.png file and the apk file, if anyone is interested.

[MTCD Android Head Units General] gustden:
I had a couple of people ask me to post the apk file for the red radio. I now have 2 versions, the first was a bit too much red. To update the stock radio, you need to replace the existing system apk ( /system/app/JY-1-C9-Radio-V1.0/JY-1-C9-Radio-V1.0.apk ) and reboot. You want to make a copy of the original one, just in case you want to change back.

Hey guys,

I'm interested in getting the Joying HU for my E53 X5. Joying has a matching HU that seems to blend into the dash nicely. I have currently still the OEM DVD unit in the car.

I'm wondering if the Joying HU will work with the OEM CD-Changer?

And also: is the rear view camera automatically activated when going into reverse?
[MTCD Android Head Units General] tuuza:
No and yes, mostly no.

As far as I know the head unit is not capabe to send commands to the changer.

But if there would be way to communicate with the changer to change/play/pause etc, it would work just by plugging the old aux-connector to the new harness.

If the supports the changer, it should be mentioned, if you are looking at model specific units. Ofcourse you can contact them.

[MTCD Android Head Units General] Saiyajin:
Thanks - I just asked them the same questions. Would be nice to still be able to play CDs since the headunit doesn't come with an integrated CD/DVD-player.

Hi, I have this unit JY-UL128N2 and don't manage to root it.

I did all the steps that I found here and the unit restart with no root. I got this message from root cheker: root access is not properly installed. Do you have any ideea what can I do?

Thanks
[MTCD Android Head Units General] vassandrei:
try this:

http://www.forum.carjoying.com/thread-469--solved-root-for-jyul135n2.html

I did the steps with my 135N2 (same internals as yours I think) and now root works.

Flashify freezes when installing zip files, but other things like kernel adiutor and viper4android work fine.

I have some problems still: in viper4android the profiles affect the "speakers" but really I want to use the headphone profiles.. how do I make the system treat my car's speakers as a headphone output? is there a build.prop mod or something? Also I have a problem where when the audio starts up it has a slight delay, so if no audio is already playing navigation instructions get cut off a bit, like so instead of :

"in 100m turn right" I head "-- turn right" only.

Does anyone else experience this? how do I fix this without just having music on all the time?

I have the universal 8 inch joying and everything works for me except 2 things.

1. Google voice doesn't say anything at all

2. I want to change the default launcher to Automate or Apex launcher but don't have any option to do it

Any ideas on either?
[MTCD Android Head Units General] dcman008:
Need to paint and maybe to some sanding but fits.

Didn't have a Dremel so I use mill, thought about using the CNC but would have been a lot of extra work.

Looking to buy one of these

Hello Members,

I am looking into getting on of these units for my old Toyota 2002 Corolla HB.

I have some questions and I would appreciate some input from members that have already purchased and used these units.

I am looking to get either SKU: JY-TL145N2 OR SKU: JY-ULS02N2

The questions I have are the following:

Is it possible to use a 3rd party OBD Scanner via Bluetooth or USB?

Is it possible to use a 3rd party USB webcam

Is it possible to use a 3rd party USB 4G dongle

Is it possible to use an (external powered) USB hub to connect more USB devices (like HID, mice etc. which are normally supported by android)

Is the Steering Wheel Control method for these units based on Resistor ladder network, or other method like canbus, wired IR?

If it is a Resistor ladder network do you have examples of resistor values used? ( not important. I can check this with a potentiometer)

Is it possible to re-map the Steering Wheel controls?

Some clarification for the Steering Wheel Control method question.

I am in the process of creating a custom made Steering Wheel Control Stalk.

My car comes with an OEM Toyota AVC-LAN SWC Stalk and I want to make my own custom SWC controls instead of buying an adapter (which are expensive and don't really exist for AVC-LAN).

If it is resistor based then I am lucky since it is simple and straightforward. If it is using any other method, I could work something out with an arduino or similar.

[ I am planning to make this a small instructable and post it somewhere that more people will have access to]

I am looking forward to hear back with your personal experiences.

Thanks
[MTCD Android Head Units General] Hilari0:
1. I'm using the OBDLink MX with no issues, so I presume any BT OBD scanner should work unless it's got some quirky protocol thing.

2-4. Someone else has to answer this, I haven't tested.

5. SWC is based on a resister ladder network, for use with CANBUS you need an adapter from PAC or similar

6. In my car, a Ford Expedition, it is 73.2ohms, 133ohms, 237ohms and 453ohms with a 3.92kohms resistor across indicating all buttons open.

7. Yes, you map the SWC buttons directly on the unit, so it works with the buttons in your car (if your car uses resistor ladder network SWC)
[MTCD Android Head Units General] KamaL:
3rd party USB webcam - DEFINITELY not for now, the intel based devices support only their DVR USB camera, check THIS link for a discussion regarding this. Joying don't seem to be willing to add support in the near future.

USB hub - I'm using a non-powered USB hub and it is working fine. I read reports that external powered usb hubs work too.
[MTCD Android Head Units General] arkroan:
That makes my custom made swc project easy!

I am guessing this means that Mice and Keyboards work ok with the usb hub?

Thank you for your answers Hilari0 :good: and KamaL :good:. Much appreciated!!:highfive:
[MTCD Android Head Units General] Need4Camaro:
I need assistance with three very big issues with my new Intel Joying JY-UL128N.

#1 Ok Google Everywhere... or the lack there of the feature... When you go to Google App > Settings > Voice > Ok Google Detection ... You only get the option to use it within the app or within Google Maps, but not on every screen such as your home screen ect.. There HAS to be a way to implement this...can anyone advise where I can atleast begin to look? Joying Support does not seem to care much for this matter.

#2 Using other talking apps while playing music interrupts both the music and the talking app and the music will not play again until restarted. They say this fixed this with the latest update but I have updated and it ONLY makes the selected default Navigation App work with music...This is not enough for me as I use 3 different navigation apps for 3 different purposes. I also use talking calendars and talking assistance... this needs to be fixed as it works fine on the mtcd units.

#3 Is there any way to change the button illumination colors? I want red instead of blue.
[MTCD Android Head Units General] tuuza:
#1 someone suggested above that they downloaded android auto or something similiar, that lets you select "when driving" from ok google settings

#3 there is option in CarMediaSettings app to change them.

[MTCD Android Head Units General] m3co:
1- I use a generic BT units, it work fine

2- No, camera unit they sell is specific because it works without unit, only takes power from USB, and there is a app so you can change the options and reveiw the videos (it records in the SD card you put direct on camera), this is great because not only revords 30 after you turn the car off, but dont take precessor power from the unit. i recomene you use the one they sell.

3- Yes, i use a Vodafone k5005 4G, it is a rebranded huawei, BUT you have to have root active so you can use the app widget "PPP 3"

4- Yes.

5- Yes, i use resistor with only one wire on mine.

6- You can do that in radio unit software, preaty easy.
[MTCD Android Head Units General] m3co:
New update (Date : Jan,4th,2017).

Looks like only UI is updated...
[MTCD Android Head Units General] CadillacMike:
i had started a new thread about this, but it probably should just go here:

there is an update available that has a new UI for the newer Joying units:

Hi,

Did anyone successfully installed Xposed on the single din radio running 5.1.1?
[MTCD Android Head Units General] demo84:
This is how I have been conned by the official Joying seller on aliexpress!! Paid 2GB+32GB unit and received 1GB+16GB unit!! funny thing is that I have noticed that after my "open dispute" period had ran out! Guys be aware!

I'm fuming!!
[MTCD Android Head Units General] Hilari0:
Have you contacted Joying directly? Their website is www.carjoying.com

You may have to battle a bit with some chinglish, but they might be willing to help you there if you cant get anywhere on Aliexpress.
[MTCD Android Head Units General] demo84:
hi Hilary,

I have send message to the seller with few photos as a proof. Will see what he says and yes I he don't do nothing about it I will try contact Joying directly
[MTCD Android Head Units General] Hilari0:
Let us know how it turns out, it's always nice to know how they deal with customer service when a problem arises.
[MTCD Android Head Units General] demo84:
Doe to time difference I will have to wait till tomorrow morning (hopefully)

In Hong-Kong is 04.39am right now

of course I will let you guys know

Please cross the fingers for me :angel:
[MTCD Android Head Units General] KamaL:
Good luck demo84

How does the Intel Sofia Headunit handle screen brightness? Is there an option to reduce brightness automatically during the night? I can't find this option in car media settings
[MTCD Android Head Units General] tuuza:
Just asking OT stuff, when ordering for ex. from aliexpress china to UK, how much do you have to pay taxes etc.? As they stock the units in UK for around 320£.
[MTCD Android Head Units General] Hilari0:
On mine it kinda works like a standard radio. Full brightness when lights are off, then it dims when I turn on the lights. You can set the brightness for each setting in the menu, or simply adjust the preferred brightness with lights on, then again with lights off and it will remember the settings.
[MTCD Android Head Units General] demo84:
Cost me around £20 extra for tax

Paid £240 for unit which was on offer (11.11)

But they declare it as a low value ($80 if I remember correctly)
[MTCD Android Head Units General] tuuza:
Oh well that sounds reasonable then to order from there. I just ended up to buy from european Joying stock.
[MTCD Android Head Units General] KamaL:
The issue is that now during winter I have lights always on, is it possible to change brightness according to daytime or nighttime, like in GPS apps as in Waze for example?
[MTCD Android Head Units General] Hilari0:
Yeah, you can simply adjust the brightness slider to adjust the brightness. That slider will stay wherever you set it for each mode, so you could even make the brightness go dim when the lights are off and then full brightness when lights are on. :)
[MTCD Android Head Units General] KamaL:
Ok so I didn't make myself clear.

During winter we have to keep lights on. Because of daylight I keep brightness almost at max in order to see well. But at night, when lights are obviously still on, the max brightness is simply too much. In practice the unit doesn't detect any changes because lights are always on.

That's why I'm asking if the unit can detect changes aside the lights on or off and change brightness accordingly.
[MTCD Android Head Units General] Hilari0:
Oh, now we're on the same page. No, I don't think it has an ambient light sensor. Mine seem to stick to whatever brightness it has been set to. Would be nice if it had one though.
[MTCD Android Head Units General] Need4Camaro:
If I were you, I would file a dispute directly through my bank. You'll more than likely be alot more successful. If they ask you to ship the product back, note that usually in most cases per law that the SELLER is responsible for return shipping IF the item is defective or not as described in LEGAL circumstances...I received a full refund from my bank because the seller wanted me to pay for shipping and I refused to so my bank reversed the charge and I didnt have to send anything back.
[MTCD Android Head Units General] tuuza:
Yeah, especially if paid with credit card it can be easily done. I guess if you used paypal, they will help you to get the money. I would first see how they react and if they insist you pay all the shippings etc. get your money returned.
[MTCD Android Head Units General] concept5400:
Same here, I really need to run at least 2 different nav apps for 2 different purposes... One in background for community sharing speed cameras and police patrols and other for turn-by-turn navigation.

I have contacted Joying about this problem, but I guess they know better what I need... Here's the answer I have received:

"We are so confusing that why you must need to use two navigation . it originally one navigation can arrive your all requirement , but why you must need two navigation ? Actually is easy operation, sorry that we do not know why you need to make it complicated .

Our head unit only can support one navigation sound come out . Actually , one navigation have all function . when you car speed is too fast, the warning sound will come out.so we think that it no need to use two navigation together ."

PS.

Am I the only one having problems with the bluetooth app? Conctac list import is not working well - it is not saving the "+" sign before the number (+44123456789 is saved as 44123456789 - without the "+"), therefore caller identification is not working as caller ID doesn't match the stored number...
[MTCD Android Head Units General] wanb1i:
That's why I NEVER buy from AliExpress! There are too many ripoff artists on there and no real program for recourse.

Didn't you check it the 1st day? I checked both of mine from Joying as soon as I received them.

Id hammer and threaten them as much as possible in hopes they'll care about their reputation enough to you a break. If they don't, you're screwed...
[MTCD Android Head Units General] kaderekusen:
Maybee u can use tasker to automatical brightness down at 18:00 pm an up at 08:00 am
[MTCD Android Head Units General] KamaL:
I think that's the only option. I was trying to avoid more and more apps in the background for keeping it reasonably fast and responsive :(
[MTCD Android Head Units General] Saiyajin:
Ok so I've received an answer from Joying
[MTCD Android Head Units General] tuuza:
The visual message about open doors seems to be the same in every new unit, the purpleish "sport car". If anyone could check if the image is just a .png etc. in some folder or app and if it could be edited.
[MTCD Android Head Units General] dayanandgp:
Hi All, Got a quick question. I want to purchase the below unit and i want to ask the experienced users if the information about " door open, climate control etc " are displayed on the " home screen ".

Can somebody help me out :) ? Thanks !
