As i mentioned above mine is very strange - its either on or off - no in between.

I have found that if it goes off, if i nudge the corners with my thumb it comes back on. Sometimes it is on for the whole day without ever going off. Sometimes i get in the car and it wont come on for ages and what i do is just bluetooth my phone media and change the source until it gets there.

i live in London so the hot & cold temps are bad for the soldering as it will expand and contract with time and then eventually just fail.

i wish i knew how to solder myself then i would just do it but i am waiting for it to get really bad then get someone to do it.
[FYT Android Head Units] midd33:
What is the highest Android version I can install on this unit?
[FYT Android Head Units] surfer63:
6.0.1
[FYT Android Head Units] nk33:
i think 6.0 mate.

But the lower versions work better. For example mine came with 5.0 and i did not upgrade to 6 as everything was working well with 5.0. i have heard some bad stories about version 6.0 if the unit was not shipped with it
[FYT Android Head Units] KamaL:
Is it possible to run android auto on these devices?

Still running Android 5.0

Any working apk?

Thanks
[FYT Android Head Units] Beatwolf:
Yes it is possible, but not directly AFAIK. Have a look here: https://xdaforums.com/android-auto/...-unit-android-auto-host-device-t3646736/page3

I have a questeion: Has anyone installed a rear view /backup camera? Anything they can recommend from Aliexpress, Ebay etc? I have a Golf 5 with a Joying PX5 and am looking to install a rear view camera if it isn't to big of a hassle.
[FYT Android Head Units] KamaL:
Guess what, HeadUnit Reloaded for Android Auto seems to be actually a very good solution, thanks!

I need to test it more thoroughly, but this finally makes GPS and network data rely on my android phone, and not the bad GPS antenna and sluggish BT tethering support of the joying unit!

I have both installed on my unit, reverse camera when I put the car in reverse mode, a simple one for eBay , any technician should be able to install easily.

Regarding backup cam , I had a camera with USB connection, and using [MENTION=916635]LBD[/MENTION]roid's excellent tips, I'm using it as a DVR which records directly to the SD card in the joying unit. Here's the thread about this:

https://xdaforums.com/android-auto/mtcd-android-head-units-general/dashcam-joying-intel-t3523305

This is the reason I'm still on the first 5.0 ROM, and never upgraded to 6.0 ROMs.
[FYT Android Head Units] Beatwolf:
Thanks for that [MENTION=342460]KamaL[/MENTION]

I've actually been fiddling with HeadUnit Reloaded myself, but can't seem to get it to work. I've been trying USB, I got it to work briefly, but now I only get a black screen on the HU. Running in Android Auto in developer mode. Can't seem to set my USB settings on the phone to "tethering" or anything else than what it selects by itself. Not sure if that might have something to do with it.
[FYT Android Head Units] KamaL:
In the app settings, you have to chose your phone in the menu. Did you do that?

Hey there, If anyone is willing to sell his Intel Sofia unit, I've been looking for one, for the BMW E46. If anyone wants to sell his, so that he can upgrade or something, please pm me.! I've been looking for one for months, never really found one!
[FYT Android Head Units] midd33:
[MENTION=4772005]DeejayTelis[/MENTION] I have one. I just got to work. I'll give you the info when I get home.
[FYT Android Head Units] DeejayTelis:
Thank you, at last! Alright send me a pm whenever you can, no rush, I've been waiting for months anyway :P . Is it for the BMW E46 and with the Intel SoFia ? Most probably the model: Joying JY-BL121N2 ?
[FYT Android Head Units] nk33:
hi mate - i have this sofia unit but it has the known issue with the screen which requires soldering every year or so.

i have replaced it with the new intel one which is much faster and more reliable. it is on a newer version of android and even more importantly it has its own DSP.

dont understand why you would get the sofia one? it was good in its day but is now way behind

if you really want one i can sell you mine - the screen works fine but sometimes if it is cold the screen is blank so if you do the soldering it will fix the issue for about a year to a year and a half
[FYT Android Head Units] bogdi1988:
If you weren't in Athens I would have sold you mine
[FYT Android Head Units] DeejayTelis:
Yeah, I think generally it's really difficult to send to Greece.. High shipping costs, and I have a great probability to pay import duties and custom taxes etc. I have to think it again, as it might not be worth it to have it sent to me from outside EU. [MENTION=1855149]nk33[/MENTION] i want the old intel sofia one, so that i can use the bluetooth mods availiable in order to connect my bluetooth tpms and other bluetooth devices freely. As i understand intel sofia has the bt chip integrated in the soc, thus i have complete control over the bt.

As of now I have also contacted the Joying Europe official support to ask if the happen to have one in stock, even though its unlisted in their site.

If anyone is selling it in the EU it would be perfect. I'll keep you notified if anything changes.
[FYT Android Head Units] midd33:
Mine wasn't that BMW model anyway. Sorry.
[FYT Android Head Units] nk33:
this doesnt matter - i think he just wants the generic double-din one that fits all double din slots....is this correct?

i had an E46 before my E92 and if i am correct in order to get double din you have to cut into theheater matrix...? have you done this? have you got a double din conversion?

---------- Post added at 10:33 AM ---------- Previous post was at 10:32 AM ----------

its not problem i could put it on Ebay on a buy now and use global shipping. job done....you have ebay in greece?
[FYT Android Head Units] DeejayTelis:
I don't believe we actually "have" Ebay in Greece, but don't worry either way.

Thank you everyone for offering to help and sell me their HUs, but it seems there is no need.

After some waiting and some long messages with Joying Europe, I got them to find me the specific HU model I need (brand new) and they will ship it to me from a warehouse in EU, and I will avoid the import taxes etc. They offered it at 300€ , shipping included.

So i believe it's a win situation.

Nonetheless, i thank all of you who took the time to answer and were willing to help. Stay awesome and have a great day!
[FYT Android Head Units] nk33:
no problem mate.

can you please put the link to the model on here?

it would be useful

thanks
[FYT Android Head Units] DeejayTelis:
Indeed it might be useful, and if someone can't find what they're looking for in their site, it's worth a shot messaging them and asking specifically for something.

Will definitely put the link once I get home from work.!
[FYT Android Head Units] nk33:
please do mate...thanks
[FYT Android Head Units] midd33:
Mine is JY-UO135N2 but it's the same as this one:

[FYT Android Head Units] surfer63:
This is an Intel sofia thread and users ask for a Sofia.

Both models you refer to are Intel 9853i units. These are not compatible (at all) and not what the users are talking about.

The Sofia models started as 5.1 Lollipop models (the capital L in the name), moved on as Android 6 Marshmallow models (the M in the model name).

Yours is an android 8.1 Oreo model (hence the O in the model name JY-UO135N2. The last figure mentions the memory: nothing is 1GB, 2 is 2 GB and 4 is .. well I assume you can guess that;)).
[FYT Android Head Units] midd33:
Easy there..... , mine is most certainly a Sofia model. Sorry if I put the wrong one down. Mine runs lollipop and looks exactly like the one in the link.

Mine is JY-UL135N2.

better?
[FYT Android Head Units] surfer63:
much better :)

and why the "easy there"?

You did mention an Intel airmont and you did link to an intel airmont (twice wrong), showing the specs of an airmont, not of a Sofia.

And you did not correct your answer (yet), with strike-through and corrected model.

Please don't think I'm heating up over this. I'm simply correcting totally wrong info, trying to make it as clear as possible..
[FYT Android Head Units] midd33:
THe link was a reference for the OP to see what it looks like since they were asking if it was a double din. Mine is a few years old now so I knew that my actual model wouldn't be shown.
[FYT Android Head Units] DeejayTelis:
Hey there, here is the link the sent me to purchase the e46 intel sofia i wanted.

The correct model number is JY-BM121N2 .

Unit comes already with android 6, but most probably I'm gonna put a custom rom in it with bluetooth mods etc, damn i love the xda devs.

And here are the specs from a random leftover page i found.

Have a great day, and sorry if i took a lot of time to post it, but i am really busy these days.

Stay awesome.
[FYT Android Head Units] tegan1110:
Morning all!

Not had any need to be active on this thread for a while, so for that I apologise!

I recently changed my vehicle, and am looking at fitting my Sofia head unit into my new car. I need to know what may or may not be required.

I understand that the Physical limitations might be an issue, but I can overcome these myself.

It's the whole CanBus box that's confusing me? I currently have the "bagoo opel-bg-03" CanBus box connected as my head unit was in a Vauxhall Zafira B. My new motor is a Renault Megane Mk2... Do I need to change the CanBus box protocol, remove the CanBus box completely or buy a new CanBus box? I'm not particularly bothered for the in car display to be fully functional, but I don't want it to break other features? Any suggestions?

TIA!
[FYT Android Head Units] nk33:
i have a BMW E92 and i had to remove all the built-in stuff (OEM) to get mine working.

the power from the head unit is not sufficient to power the speakers so i needed 2 amps - one for my sub and one forthe speakers.

good luck!!
[FYT Android Head Units] midd33:
I am trying to root my 2nd joying. Method 2 found on the first page of this thread is no longer there: https://drive.google.com/file/d/0B4q...ew?usp=sharing ( modifies existing boot partition )

Found it!
[FYT Android Head Units] 2zas:
Hello, I hope someone can help me with the recordings of the front camera (Joying). It does not record continuously using the space of the sd card, it only records clips of 1, 3 or 5 minutes as configured in the application (and not in loop, but a couple of them per trip). I am using the Traffic Guard application and it only gives me the option of 1, 3 and 5 minute recordings but I don't see any "continuous" recording options for it to use the full capacity of the card. Do you know of any application that allows you to configure the camera to record continuously?
[FYT Android Head Units] surfer63:
That is on purpose for all dashcams in the world (as far as I know).

What do you think will happen if you switch off contact? Your 1½ hour full-recorded trip will be corrupt, meaning that you have nothing.

Or in case you have an accident which you want to have recorded and all power is suddenly lost? Again a corrupted video and no evidence.

If you want to concatenate the mp4's to one single mp4 afterwards, use something like described here.

(That's how I do it but slightly modified in a script and on linux).

So yes, you have to take the sdcard out of the dashcam, but I use 2 sd-cards anyway.
[FYT Android Head Units] 2zas:
I think you have not understood me (or I have not explained myself correctly). In the Traffic Guard application (which is the only one that has worked for me with this camera), you only have options to record clips of 1, 3 or 5 minutes. A 1 minute clip weighs approx 100mb. On a 16gb card you should be able to record hundreds of clips, but it only records 5 or 6, that is, it only records the last 5 or 6 minutes in general. My question is if there is any app that allows you to configure the camera (the camera itself, not to record in the memory of the radio) so that it is capable of continuously recording clips (either 1, 3 or 5 minutes) until the card is full ... like any dash cam.
[FYT Android Head Units] surfer63:
I now understand, but it is weird. I also use Traffic Guard and never have an issue, apart from the fact that the first clip is never OK, but I record 1 minute clips so I only miss the first minute.

Please remove the SD-card and do a file check or clean format. When the dash cam switches off it never cleanly unmounts the SD-card which can result in corrupted parts on your SD-card. After some time that become many corrupted disk segments.

Which Traffic Guard version do you have? The one delivered with the camera is an old one. You can download a newer one (which is still old btw).
[FYT Android Head Units] lenniedelfuturo:
Hi all, first time long time. Have been having some trouble with my JY-UL135N2 i purchased on Amazon in Sept 2017. I realise i have gotten fair mileage (literally) out of my head unit but am just irked that i can't get it to work. I was rooted and had the Gtx Rom from [MENTION=520205]gtxaspec[/MENTION] and Joying Extra Tools from [MENTION=2550900]surfer63[/MENTION] installed for the longest time but recently was having trouble with the Headunit Reloaded app displaying properly. I was attempting a factory reset and fresh install of everything but my unit hung up when trying to reinstall GTX rom through the custom.apk. I then tried to reflash the Joying stock rom for my head unit from their blog, it seemed to take but on rebooting shows the 'android 6.0m' logo then flashes to a white screen, shows logo again, then switches off and loops through that again. i have tried to reflash numerous times with the same outcome. Wondering if someone on here can point me in the right direction.

I have purchased the newer Joying sc9853i and am currently installing that but would love to know if the old unit can be fixed.

Apologies if this is in the wrong thread, etc. as am not very well versed on forum etiquettes in general. I realise this isn't a 'please help me' thread but have seen other questions answered on here. Please advise if this is the case and i will delete and create a new thread

As i havent posted here before i can't currently add links to the loop video and stock rom installation i have made or any screenshots i have taken

Thanks in advance.

Lane

just wanted to add that i have scoured the posts on here and elsewhere trying to find the answers. have used a keyboard to get into recovery but couldn't do anything from there. also tried the pressing reset button 3 times trick but lights on buttons did not blink after 4 or 5 resets.

i can get the unit to recognise usb and begin flash. so not sure what exactly im doing wrong

I’m looking for the latest/last available ROm for the JY-UL135N2 running Android 5.1.1. The links posted throughout this thread appear dead. Thanks.
[FYT Android Head Units] lenniedelfuturo:
i can't add links but joying dot com slash blog has an intel sofia page with 2 different update versions. Not sure if that's what you're looking for?
[FYT Android Head Units] midd33:
Thanks but I think that's for Android 6. I reached out to Joying. They are sending me a file.
[FYT Android Head Units] midd33:
Joying no longer has any firmware for Android 5.1.1. So I’m still looking.

Is there a way I can use the firmware from one of my units for another? As in a recovery mode?
[FYT Android Head Units] lenniedelfuturo:
I might have an old copy from when i 1st got the joying in 2017. Will look when i get home
[FYT Android Head Units] midd33:

Hi

Help me please update for this radio car android
[FYT Android Head Units] D1v3Lx:
Helpppp????
[FYT Android Head Units] surfer63:
You can't. Android 6.0.1 is the highest version for this Sofia 3GR. Not one single manufacturer or reseller supports this unit anymore.
[FYT Android Head Units] bogdi1988:
Run a different launcher and set the launcher itself in immersive mode?
[FYT Android Head Units] booba5185:
I was able to figure it out and get it working using the method in the first post. Only problem I'm having now is steering wheel controls. Whenever I have Key1 or Key 2 connected to ground (and the other key wire connected to the steering wheel wire of my 2000 Grand Prix) the app acts like there is a key constantly being pressed on the steering wheel, it says "Press the key you want to learn" in Red text. If I disconnect the wire from ground, the app changes to a green messages saying "Press the Steering Wheel button" or something of that sort. Nothing ever works. I've searched this thread and I'm currently googling it to see what I can't find, but can anyone help me?
[FYT Android Head Units] bogdi1988:
You shouldn't connect Key1 or Key2 to ground.

Are your buttons resistor based? 2 wires on the wheel? 1 wire should go to ground and then only 1 wire goes to head unit to either Key1 or Key2. Then, you hold the button you want to program and then in the head unit you press on the respective button to record the value. That was what I had to do - numbers were going all over the place.
[FYT Android Head Units] booba5185:
I have only 1 wire on my steering wheel controls. The Joying site said that key1 or key2 should go to ground and the other should connect to my head unit. How should I connect it up?
[FYT Android Head Units] bogdi1988:
Just 1 wire to Key1 and that's it. Most likely in the steering wheel, the manufacturer sent the second wire to ground already.
[FYT Android Head Units] booba5185:
I tried it that way and the head unit never registers that I push the steering wheel button.

Edit: Just went and double checked, Key1 is wired into the car, Key 2 is wired to nothing at all. Head unit never registers a steering wheel button being pushed.
[FYT Android Head Units] bogdi1988:
So when you press a button in the button assignment screen, the values don't change at all?
[FYT Android Head Units] booba5185:
Correct, nothing happens at all.
[FYT Android Head Units] bogdi1988:
Ok. Then do connect the other Key to ground as Joying says, but then when you program the buttons, first hold the button on the steering wheel, and then press the button on the joying unit in the config app. You might have to press that a couple times until it "sticks". Then save and it should work. If not, you *might* need a PAC interface like PAC SWI-RC
[FYT Android Head Units] booba5185:
That's what I spent the most time trying, When I have it connected that way a few numbers change here and there, but nothing changes when I press steering wheel buttons, and the red lettering telling me to select a button is displayed.
[FYT Android Head Units] windowsdan4216:
Anyone??
[FYT Android Head Units] gustden:
It sounds like the task killer is not removed. Which APK file did you download and install? Are you sure in was installed correctly, and system is not using the original apk?

I do not have this issue. I can set google maps for a destination, shut my car off overnight and it still remembers where I am going the next day.
[FYT Android Head Units] surfer63:
Check the exact size in bytes for your downloaded apk. Not something like "1.3Mb", but like "1297368" (note: this size is only an example so show what I mean. your apk might be different)

Then do a

adb connect <unit ip-address>
adb shell "su -c ls -l /system/app/Sofia-1-C9-Server-V1.0"

You should have 2 entries. A renamed previous apk and a Sofia-1-C9-Server-V1.0.apk with the exaxt same size asyour downloaded apk.

Hi folks, I found the OEM Boot Logo / splash screen .bmp file while rooting around in the system folders.

I also grabbed the OEM Boot Animation .zip file.

This might help up get going with custom boot animations as we go along.

Note that the Boot Animation must be kept in a .zip file. It appears to be store only, that is, no compression.

The Splash screen must be kept as a .bmp file. I have zipped it up here to allow me to post it. Decompress, modify, then over-write the original in the system folder.

Good luck!

Any luck getting bluetooth to stream music from your phone while in Nova Launcher? The "app" for the bluetooth music is on the stock launcher only, it seems.

For some reason, my Nova Launcher doesn't have the app drawer button on it when I switch over.
[FYT Android Head Units] thedru13:
I still have the Bluetooth music app in nova launcher. So I am able to stream music via Bluetooth.

I also had that happen with nova launcher with the drawer button. I couldn't figure out how to re add it. So I uninstalled it and re installed and that fixed the issue for me. Just a pain to reconfigure every thing.
[FYT Android Head Units] windowsdan4216:
Thanks for the response. I downloaded V2 of the file and unzipped the file and moved it to "/system/app/Sofia-1-C9-Server-V1.0/" set the permissions to "rwx rw- rw-" and the owner to "root" and the group to "root".

I do have two files in there .. one that is like 1.21MB and one that is 1.24MB (1297355).

I'm hoping this was the right move?
[FYT Android Head Units] surfer63:
See this post. Probably an issue with renaming
[FYT Android Head Units] windowsdan4216:
Unfortunately this is not the issue, as I have renamed the entire file (inc. extension), but I have no issues with anything else working.

When I reboot it does say that it is optimising 1 application, which it is supposed to do, but still I get the problem where apps are resuming after leaving the car but not with the data they had in them when I turned the car off. I even removed the old .apk (after backing it up) so that only the new one is in the folder ... still no 'joy' :-s

Does it have anything to do with me using Nova launcher?? Really would love to have a fix for this, short of putting in a relay switch between the ACC cable and the permanent live and just switching on the 12v+ cable when I'm leaving the car for an hour and switching it back to ignition when I intend to leave the car overnight or longer.

:(
[FYT Android Head Units] windowsdan4216:
Having tested as thoroughly as i can, it seems like after about 10 mins of the HU being off it forgets things. Not what is open but what was happening in those apps.

Should i expect that if i was, for example, playing atune from Spotify it would continue to play where it left off if i came back to the car half an hour later. It doesn't. It will remember Spotify was open but the app fully reloads again and certainly doesn't start playing the tune from where i left it.

It does do all of this if i turn the car back on within 10 mins though. :crying:
[FYT Android Head Units] bogdi1988:
That's the fix that requires you to replace the Sofia server app - it kills all services in sleep.
[FYT Android Head Units] windowsdan4216:
If you read back a bit you'll realise I have already done that and it doesn't work.

I'm running the JY-UL135N2 on the March update ... wonder if it's that or that I'm using Nova launcher, if the Sofia Server app works for everyone else :confused:
[FYT Android Head Units] bogdi1988:
Can you try the v2 patch for the Jan 5th version? I just used it on my unit with the 3/14 update and works great!

I'm using Nova launcher also.
