I´m reading this thread for a while and also consider to order one of theese.

I bought a citroen C3 Pluriel last week and would like to have a modern System in it. Maybe there is somebody out there who tried to implement a Android system in citroen.

But to the rest of you guys.

Have you implemented the back camera? Do somebody know how to wire it?

Did i got it right that it is quite easy to get the steering wheel to run? It looks like you only have to conect it and than you only have to program the functions?

What about Bluetooth now? Really only the phone and OBD? I would like to use a gamepad and some other things. Has somebody tried to use the usb to connect maybe a wireless keyboard or something?

Has somebody build in the radio extender for active support of the radio antenna?

@ CadillacMike, thank you very much for your review and the video. That was really helpful!:good:

Does 'OK Google' from any screen work with these?
[MTCD Android Head Units General] doitright:
Sound output quality is fine, but mind you, no hi fidelity audio buff here, I use, as I already mentioned, AM radio, and am reading it off frequency. GMaps nav voice is clear, phone calls sound fine as long as the other end is producing decent sound quality to feed in. Example: wife with Google Pixel using handset sounds clear, friend with Nexus 5x through Toyota Corolla and "factory"-ish bluetooth/nav head unit sounds muffled and overly compressed.

There are definitely some problems with the contacts handling.

I had a problem convincing one of our two units to even synchronize the contacts.

I think what happened, is it attempted to download the contacts list over bluetooth prior to the google account being added, which corrupted the contacts database. After the google account was added, it refused to synchronize with a cryptic error message. To correct, I had to delete and re-add the google account, and clear contacts, contacts storage, and contacts sync, then retry the sync. I'm not sure which of those actions actually fixed it.

Did you actually hook up the reverse wire?

Yup, DPI setting should be much larger. They're using the same system image across the board, so they probably set it up for the 10 inch screen.

---------- Post added at 03:12 PM ---------- Previous post was at 03:06 PM ----------

I have a camera, but not yet installed. I'm going to be hooking it up to the video in plug, NOT the backup camera plug. I don't like backup cameras, just want it to simplify trailer attachment, so turn on as needed rather than automatically every time I put it in reverse.

If your steering wheel is a standard 1 or 2 channel resistive to chassis negative, then yes. Just wire it straight in and then program the functions.

Bluetooth stack is **FULLY FUNCTIONAL**. Caveat is that on the Joying, they cripple the Settings UI to block access to the bluetooth settings activity, leaving bluetooth configuration to their ABSOLUTE TRASH "bluetooth" application. Check for my thread containing blueballs.apk -- you can install that to regain access to the factory bluetooth activity, and regain full bluetooth functionality.

Not sure I understand what you mean by "radio extender". One of our cars has a powered antenna, and it seems to work on their antenna wire.
[MTCD Android Head Units General] CadillacMike:
there should be an option for this in CarMedia Settings
[MTCD Android Head Units General] doitright:
The default setting for it is 10% volume reduction. If he didn't discover this setting already, then it should drop by 10% anyway.

Guys.

Did anyone successful rooted latest 08.12 software via ADB? I have followed step by step guide and it seems OK and after reboot the supersu.apk is not installed. So I did it manually and it says device not rooted. Hmmm
[MTCD Android Head Units General] eta1405:
I'm considering purchasing this unit and replacing my NU3001 with xdauto rom. Has anyone done this and can give an opinion, maybe a comparison? I know it's kitkat vs lollipop but was it worth it?

Do any of you guys with the larger screens remove it when you park for anti theft purposes? I'm wondering about the screen durability after repeated removal/replacement.
[MTCD Android Head Units General] doitright:
"supersu" is not root.

Aside from being a trojan, supersu tries to pass itself off as an ACCESS CONTROL application.

These head units SHIP WITH root.

adb connect <ip address>

adb shell

$ su

[MTCD Android Head Units General] demo84:
Of course is not the root. This is permission app. But it won't work without root. Simple as that.
[MTCD Android Head Units General] CadillacMike:
i never had a kitkat unit, but I did have a 1GB RAM Android 5.1 MTCD, and now I have the 2GB of RAM units with Intel, and I can't imagine going back. At the time it seemed fine, but now when I use the MTCD it feels slow as a snail.

I have the 8 inch screen that is removable. While it is secure and does not rattle, I would not trust those clips for frequent removal/replacement, seems like they would wear out.
[MTCD Android Head Units General] doitright:
If you think you know the answer, then WHY DID YOU ASK THE QUESTION?

And no, it is not just a question of "it won't work without root", for it to work, you need to replace "su" command with **ITS OWN**, which is not trustworthy.
[MTCD Android Head Units General] demo84:
I have notice and probably not only me. Apart from your a *bit* of knowledge you represent nothing but arrogance. So do me a favour, go and be a d...khead somewhere else!

Hi

I was going to upgrade my vw radio and thinking to bought joying unit, is there any reason to not to bought 9" version with no fysic buttons or are there some reason you need fysic button? i got steering wheel control so i can use them to adjust volume etc.

Is there anything else i need to know before purchase?

(sorry for bad english :D)
[MTCD Android Head Units General] jonssoni83:
I did find that setting, and tried 10%, 20% and 50%, but nothing happens. It doen't even show me that overview picture of my car and radars. That did work with the previous software. Now running that Dec 8 software.

You can send me priv messages in Finnish if you like, I live in Turku and own that 9' model without buttons.
[MTCD Android Head Units General] bardzogrozny:
Hey,

thank you for all of the reply.

Like i see, there are some other new head units from Pumpkin that are also equipped with extended 2GB of ram. What would you say performs better? Cortex or the Intel? A am asking because the range of equipment at Pumpkin is much better than that in the Joying shop. Also the HU is about 100 bucks cheaper.
[MTCD Android Head Units General] jonssoni83:
How did you disabled contacts sync, or how did you removed Google account? Wondering because there is no Accounts option in Settings anymore...
[MTCD Android Head Units General] bardzogrozny:
Hey Thank you for the explanation.

You can buy a small amplifier for the radio signal at the online store of Joying. I thought that could help to get a better radio signal. But as i understand it now it is only for cars that already have an activ antenna? Am i right? Or is it possible to implement it in every Car?
[MTCD Android Head Units General] KamaL:
Question about shipping : I bought the JY-UL128N2 unit from the official Joying aliexpress store 5 days ago, and they supposedly sent it to DHL for delivery on the same day, at least that's what they claim.

Since then, the tracking number gives this notice:

"Shipment information received"

And it didn't change since then.

According to the seller, he sent the product but because of the busy period, DHL hasn't processed the shipment yet.

Being skeptical, I sent an email to the DHL customer service in my country and they claim that this message means that they didn't receive the actual product and they're still waiting for it from the supplier!!

Are they lying to me? Is this wait reasonable? Is it a fake tracking number, giving joying time to finish the product and then ship it with the correct tracking number?

This already happened to me once with another Chinese supplier, and I really hope I'm wrong.

Anyone experienced something similar?
[MTCD Android Head Units General] wanb1i:
We've all experienced this problem. Personally, I think they're made to order and it takes a few days for them to build it. The go online and get the shipping done and send you the tracking number so you don't harass them, then, when it's built the ship it. Takes a few days to get to DHL. Mine went to DHL on Saturday, it's at my local post office today, hoping to receive by tomorrow. Be patient....
[MTCD Android Head Units General] KamaL:
This is simply unacceptable.

How much time did it take since they sent you the tracking number until they actually handed it to DHL and got shipped to your country?
[MTCD Android Head Units General] wanb1i:
Unfortunately, this is typical Chinese order process. It took 4 days (including the weekend). I had my 1st unit in 10 days from order to receipt at my home. I'll have this one in about 8 days. Considering the product is traveling half way around the world, that's not too bad.

I just received notice that my 2nd unit is out for delivery today! So about a week total.
[MTCD Android Head Units General] doitright:
I didn't disable contacts sync. I CLEARED ITS DATA.

The accounts button comes back if you actually install the system update to your unit.

So either suck it up, or shut up.

The pumpkin is also running Android 4.something and lying about the version.

---------- Post added at 03:22 PM ---------- Previous post was at 03:20 PM ----------

As I understand it, some car antennas actually feed power up the coax, which means that you would need a power injector in order to activate the powered antenna. In order for this part to work, you would actually need to have a factory powered antenna and NOT a separate power line that runs it.

---------- Post added at 03:24 PM ---------- Previous post was at 03:22 PM ----------

They pulled the same crap with me. Yes, they ARE LYING TO YOU. They waited about a week before actually handing the package over to DHL. Once it was in DHL's hands, it went from Hong Kong to Toronto Canada in 2 days.
[MTCD Android Head Units General] bardzogrozny:
Do you think it would be a problem buying Pumpkin equipment like the Camera and use it with the Joying?
[MTCD Android Head Units General] m3co:
I have a problem with my unit, it did not record some of my setting, like radio station and some defenitions, but it record other, like the buttons color why is this?
[MTCD Android Head Units General] jamiphar:
I'm about to order one of these. I'm leaning towards the 10.1" model, even though I generally prefer a volume knob. Are there any notable differences between the 7", 8", and 10.1" models other than physical controls and screen size?

Also, is it better to order from Amazon or directly from Joying?
[MTCD Android Head Units General] Blaze Falconburger:
I ordered from the joying website on 6th December, order still on Processing so emailed to find out:

Just check with our factory, your head unit will be send out next week

As it is busy season, also there are many people order this head unit as it is newly release 2GB ram

So indeed have some delay than usual

Hope you can understand

Do not worry, if we get the tracking number will let you know asap

So maybe these new units are built to order or they just can't meet demand
[MTCD Android Head Units General] doitright:
The "guts" are all identical.
[MTCD Android Head Units General] KamaL:
Wow, I ordered on the 10th of December, and they sent my a tracking number right away, but seems to be a fake one...

Thanks! I ordered the 10.1" from Joying and a 128GB MicroSD card. I'm eager to try it out!
[MTCD Android Head Units General] oma:
I have two questions for someone who has this unit:

Is it possible to connect two bluetooth devices at once, e.g. a phone and an OBD adapter?

What's FM reception like, compared to stock or name brand radios? Assuming equal input signals, i.e. with a power injector installed if necessary.
[MTCD Android Head Units General] ikerg:
Why dont you look some pages back to look for the answer?

Can someone comment on FM reception compared to "good" radios, preferably from actual experience while driving through areas with varying signal quality?
[MTCD Android Head Units General] ikerg:
Comparison has been made with stock radios....and people said that it sounds better. I have not seen any noticeable difference with my old pioneer appradio 3. But I have still my stock speakers so ...

[MTCD Android Head Units General] doitright:
Its not a "fake" one. The tracking number is perfectly valid, they just haven't actually handed over the package yet, which is why the tracking number doesn't show any activity.

---------- Post added at 03:09 PM ---------- Previous post was at 03:01 PM ----------

Has anybody yet looked into the video camera situation?

Last night I tried to hook up a USB video camera, one that worked on previous MTCD (though obviously that unit didn't have the horsepower to do anything useful with video), and got nothing but blank screen.

Is the problem at the driver level? Or is it at the HAL level? Anybody notice whether the kernel on these supports loadable modules? Worst case I suppose we could build up a userspace driver. Best case, the problem is at the HAL level.
[MTCD Android Head Units General] Blaze Falconburger:
All in the timing - I have the tracking information now, but no movement yet
[MTCD Android Head Units General] rcll:
The rearview camera via RCA input works as expected on my unit. I haven't tried a USB camera but I saw Joying says they only support their own USB camera. It could be they are whitelisting it by its USB VID/PID.

Were you able to find a method to enter recovery from power-off on your unit? I'm wondering if Xposed will work on this unit but without a way into recovery its a bit risky. I checked MMTK84's video but holding ALT and Print with USB keyboard my unit does not reboot like his unit, which seems odd since the non-MTC Intel units should be the same other than DIN size and screen size. You mentioned that even then its likely not true recovery. Have you figured out what Joying is doing with that microvisor?
[MTCD Android Head Units General] doitright:
That input is irrelevant, since it can't be recorded.

And I'm just trying to find out if anybody has yet bothered to look at where the breakdown is.

I haven't really had any time to look at the recovery aspect of it.
[MTCD Android Head Units General] rcll:
I used an RCA Y-splitter to send the rearview camera signal to both the rearview camera RCA input on the breakout cable and the "V IN" RCA input on the back of the unit. Its useful if you want to see the rearview while driving.

Theoretically you could capture the video coming from the "V IN" input. Its analog of course but the "AUX" app seems to grab the analog video.

For a digital camera via USB there should be no reason that only Joying's camera will work, whitelisting only their PID seems like the most likely explanation.
[MTCD Android Head Units General] CadillacMike:
I didn't realize this would work, i thought switching to Reverse triggered it.

so you can just put in a Y splitter and it will be on at all times if you hit the AV IN app?
[MTCD Android Head Units General] rcll:
Yep. I did it with my old MTCB, confirmed also working with the Intel. Its pretty handy to keep an eye out if you're towing, or just to check the rear in general while in forward motion. I'm not sure if the app is going through the MCU to grab the analog video signal but it displays it fine. If it exposes it to other apps that have a recording function that could be a clever way around Joying's USB camera blocking.

You also need to wire the rear camera to 12v accessory or ignition power, not switched reverse tail light power.
[MTCD Android Head Units General] doitright:
No, sorry, it doesn't work that way.

The video signal NEVER reaches Android.

When you use the aux application, it doesn't actually play through Android, it actually goes straight from the vin cable and back out. Same with the backup camera.
[MTCD Android Head Units General] rcll:
Thats a shame, since there is clearly some hardware in the unit to handle the analog video signal. Would be nice if it exposed it on an OpenGL surface or something that can be captured. So V IN is just a passthru from the MCU?
[MTCD Android Head Units General] doitright:
Yup. Just a pass through.

JY-UL135N2 Comments

I just got Joying JY-UL135N2, it seems really nice, easy to root and setup. I do have a couple issues/grips:

1. Whoever designed these needs to go back to school about thermal design. Just doing some testing it was quickly being throttled back to 900MHz and CPU temps were near 80C ( in a 19C environment ) ! I happened to have an extra CPU heat sink laying around so I decided to put one on the main chip cover with some double sided thermal tape. Now it runs in the mid-50C and runs at the full 1.04 GHz. I'm seriously thinking about putting a fan in the top of the case also.

2. I have set up google voice on the head unit and it works fine, except I cannot make a call. It finds the contact and attempts to dial but does not find the phone/bluetooth application. I can go directly to the phone/bluetooth app and make a call just fine. Any way to have google voice see and use the BT dialer?

3. I have tried to install other other launchers, and the dock is always on the right side and no way to correct. Stock launcher is OK, but I would like to change. Any thoughts?

4. Is there any way to assign a steering wheel key to a specific application? It would be great to have a steering wheel button to start a google voice query, especially if it could pull up the BT dialer and make a call.

I am running the latest ROM from Joying from 12/8/2016.

Any one else run into these issues or suggestions?
[MTCD Android Head Units General] doitright:
Yup, nothing can be any easier than "it ships from factory with root"....

You're asking too much from CHINA.

But at least with Intel behind the bulk of the CPU, it actually does throttle. If it was all rockchip behind it, it would just melt itself down.

That is one heck of a big heat sink!

However, I would be concerned about thermal tape eventually letting go, especially in an application that vibrates and shakes around like a car does. Probably be a good idea to fasten it down with something a bit more sturdy.

You'll never get it to play nicely with the crap china dialer, unless you decompile and modify it. Normal dialers won't work on this unit.

What you should be able to do, however, is place voice calls through HANGOUTS. It can make and receive google voice calls via VoIP.

I actually like it on the side like that! But to each his own, eh?

There are a million different launchers. I would suggest that you keep looking, there's bound to be one that is configured how you like, or one that can be configured.

The older MTCD units were actually a lot more configurable, in regard to steering wheel buttons. Still not quite what you are asking for, mind you. The exception, is GPS. You can configure a specific application as the "GPS" application, and a button to trigger it. In fact, the GPS button is a bit better than just launching an application, it actually *switches* between two applications. Whatever was there before you pressed the button, and whatever you configured it to launch.

So for example, if you start Torque, and then press the GPS button (lets say google maps), then the gps button will TOGGLE between Torque and GMaps.

"Ok google" works like a charm. I have the mtcd version and I have the same issue with not making the calls.
