For what it's worth, I used to own a joying UQ-124. I still have it actually but I stupidly destroyed it trying to do the audio mod. I liked most of the aspects of it, but by far the biggest annoyance was how poor the BT phone call quality was. Even after doing the bt audio mod, my wife complained about how poor the quality was.

There is a newer generation of units floating around that have slightly better specs than the joying. Very few people on xda own one. I managed to find one made for my car, and I can say without a doubt it is better than the joying unit in almost every way. I did a mini-review here -

http://xdaforums.com/android-auto/a...eration-4-4-2-android-21u-ouku-t3230587/page3

in summary BT calling is excellent out of the box, came with a better external mic, better wifi antenna, and just built better than the joying in every measure.

I fixed most of the niggling issues I mentioned, like pairing the BT OBDII module. The only issues I have now is that I can't re-map my SWC using their built-in app, and my phone doesn't auto-pair with the unit which my be a phone issue & not a HU issue. Everything else has been great, though I do feel the AN-21U stock rom is even more limited than the joying stock ROM. If we could get more dev support on board it can be a real winner, but even running stock it's better than a joying.

Only other thing that sucks is you can't find them state-side, I had to get mine from ali express and it took a fair bit of searching to find one with the right specs. Only found one seller offering it, a seller named "smart rover".

Good luck. Like I said I'm not here to crap on the joying unit, I liked mine a lot, but my new unit is simply a higher quality unit.

Any idea who makes them?
[MTCB Android Head Units General] Hisma:
[MENTION=6977411]Sasha0574[/MENTION] no one company seems to make them, they are all sold by 3rd party sellers. The R16 is a newer chip so units with this hardware just started popping up in the last 2-3 months. If you search "quad core R16" on ali express it seems to be an easy way to see sellers offering these new units. It's sort of a crap shoot because I don't know if quality varies by 3rd party seller, all I can say is my smart rover unit is a relatively high quality device. I don't even know if anyone offers a universal double din model, but I haven't tried looking.

Joying is just another hui fei variant. So theoretically joying or pumpkin or whomever could offer a model with this hardware as well.
[MTCB Android Head Units General] Sasha0574:
Hmmmm... could this be the case with the coreboard they sent me to replace the one that broke? After changing it, I had a feeling that it started working a bit better and faster... could they have switched to the new version aswell... Rambo did tell me they knew of some trouble with the chips and that they "fixed it"...
[MTCB Android Head Units General] DWilks:
[MENTION=1314697]rickthecabbie[/MENTION], Thanks for the info. I will keep mine the way it is because

I don't want my camera powered unless I'm using it and also I already have a front dashcam mounted to the windshield with its own micro sdcard and it's HD video. I agree with [MENTION=6977411]Sasha0574[/MENTION] about not wanting to always have power applied. I'm also using a SJ4000 camera(gopro knockoff) mounted to my rear window with HD video with micro sdcard. The rear camera that's connected to my HU is for connecting to a boat trailer and just to view rear to the side traffic. Thanks for the idea though-:)
[MTCB Android Head Units General] Sasha0574:
I should say thanks aswell for the rear surveillance idea... well, actualy, considering how these guys drive here, I should have a full 360 surveillance system...
[MTCB Android Head Units General] asdrewq:
Interesting. Do you have any pictures of the internals of your new unit/pics of the microphone etc? Is 'r16' a newer version of the Rockchip processor? Most of the ones I can find on aliexpress look to be running 4.4.2, not 4.4.4 like the thread subject joying.

The one thing I immediately don't like is the rca outputs being bundled in an external connector bunch using a non shielded interconnect to the main board. If you have used the rca outputs I'd be interested in hearing your thoughts on any interference evident.

The manufacturers/distributors of these certainly don't make it easy to keep track of what's what!
[MTCB Android Head Units General] Hisma:
well I don't have any particular reason to open up, but I might get curious and look. If I do I'll come here and post pics. The r16 is an allwinner chip, but it was released May of this year. Despite this it is similar specs to RK3188, except that is has access to a L2 cache that rockchip lacks. Having ran the joying and my new unit, I can say the R16 feels smoother, though not by any notable margin. Just "slightly" better. Strange thing is that all references to allwinner R16 you find online point to a quad core R7 chip, but the R16 in these HUs definitely have A9s, as it is verified when checking hardware settings.

I have an amp coming in next week so I will be testing the pre-outs very soon. I am also curious how well the unit sounds with premium audio. The stock equalizer is unfortunately just as crappy as the joying. It seems to be universal w/ these units that they don't consider audiophile features.

---------- Post added at 07:15 PM ---------- Previous post was at 07:11 PM ----------

I don't think this is the case. Could just be a placebo of having your system working again ;). There may be some minor changes to the board layout, but any significant hardware changes would have required you to flash new firmware. ROM must be compatible with hardware, so any change to hardware requires an update to compatible ROM/firmware.
[MTCB Android Head Units General] Sasha0574:
That.. I dunno.. and I didn't bother to look at what it says in the "about device" since I changed the board, and the software was preloaded. But it definitely feels smoother, and since I'm crawling with Androids, I could pretty much guess the difference between placebo and the real deal. Now I dunno if it's some other chip, or an improved version of the old, but it does feel better... as for the sound... I'm operating without an amplifier, but I left the units native equiliser to flat and fiddled with the goodies inside JetAudio, it's own preamp, equiliser, crystaliser and the Bongiovi DPS (AM3D appears not to be too useful in a car, creates too much distortion) and after... well... about half an hour of tweaking them I got a more than satisfying effect... dunno if it would blow my speakers if I were to turn it loud, but since I never go above 13 on the unit's scale, it works quite well for me...
[MTCB Android Head Units General] Hisma:
Ahh, well if it came with preloaded software, then you very well may have upgraded hardware. You can visit the hardware overview page, it could confirm this for you.

Hi, i bought one from Carjoying on July for my Skoda Octavia RS 2007.

Can't post URL, it's the first one for VW at EU Warehouse section.

Phone calls using included external mic are OK.

Sound quality is as good as it was with my old Parrot CK3100.

Regards
[MTCB Android Head Units General] jbleasdale:
I believe that a USB powered external 2.5" hard drive should work with the Joying units - is this right?

I presume that it will need to be formatted as FAT32 and USB2 compatible.

Does anyone know whether USB3 drives will work, so long as backwards compatible with USB2? Or must the drive be USB2 only?
[MTCB Android Head Units General] mrr19121970:
Usb3 is backward compatible
[MTCB Android Head Units General] Sasha0574:
USB 3.0 is indeed backward compatible, but aparently, from what others say, will not work on these units. Also, it will aparently take USB 2.0 external hard drives of up to 1TB...
[MTCB Android Head Units General] jbleasdale:
Thanks Sasha!

Has anyone tried a USB 3.0 stick or drive? Do any work?
[MTCB Android Head Units General] Sasha0574:
See the big thread, maybe I'm wrong but I think there someone expressly warned against using 3.0's since they cause problems... I might be wrong but that's how I remember.

Anyone know how to get music titles/artists/covers to show up while using bluetooth from my android phone? Thanks
[MTCB Android Head Units General] vlaine:
Can you help me fix my Joying issues please

I installed my Joying RK3188 head unit this weekend and played a lot with it.

I kept all my questions to send in a single post.

I hope you can help me with my questions.

My MCU version is 2.73

1. Mirror Link:

When I follow the instructions, I don't have the Mirror Toggle button on my iPhone 6.

I am running iOS 9.1 and the latest Android Head Unit version (2.73). What Am I missing?

2. Bluetooth music:

Somebody asked it in the previous post. I can't see any information about the song playing. I only have the 3 buttons: play/pause, skip forward and skip back.

How can I see the album artwork, the song title and the artist name ? In the screenshot below, a song is actually playing.

3. Bluetooth Contacts:

How can I sort my contacts by first name

4. Contacts:

Can I set favorite contacts somehow ? Is there a 3rd party app that can do that ?

5 Weather App

The app is showing the weather for the wrong day. In the screenshots below, I tested weather app on Sunday, but it's showing Friday instead.

5. Weater App

I am unable to get weather weather for the current location. When I am in the Weather app at the current location section, if I hit refresh, it spins for ever.

Location is activated for the weather app.

6. iPod:

I installed the iPod application from the Factory Settings menu. I plugged my iPhone 6 with a lightning cable to the head unit usb port.

When I start the iPod application, it doesn't see my iPhone and closes immediately. Am I missing something. Is it normal ?

7. Video:

How can I Airplay videos from my iPhone to my head unit ?

If you know a fix, a workaroud, or 3rd party apps that could fix some of my issues I would greatly appreciate your suggestions.

Joying RK3188 mini-review

I received my Joying RK3188 (VW specific model) yesterday and installed it in my Mk6 Golf in under 10 minutes. It arrived with the latest software build pre-installed and so I was up and running almost immediately.

The build quality is good with all buttons and controls feeling responsive and sturdy and the plastics a great match for the car - it really doesn't look like an aftermarket unit once installed.

So far I am very impressed and very happy. There is no competition between this and my previous stock VW RNS510 HU!

Joying customer service has been excellent so far and shipping from Hong Kong was very fast.

In response to a number of queries and themes in this thread:

The in-built microphone seems to work well for me with no interference or background noise (tested with Skype so far, but not tested for calls). I haven't even plugged in the external mic.

I left my factory fitted Bluetooth in place and am actually getting the bonus of using this to initiate and control calls from the dashboard display and right hand steering wheel controls. My iPhone then uses the Joying unit for audio so they coexist just fine.

I used a USB3 stick with no problems at all.

Sounds quality from apps is superb - very pleasantly surprised. Bluetooth not quite so good. FM radio a bit muffled (but may relate to my Fakra antenna questions below)

Questions:

Are there any settings to adjust for right hand drive cars (I am in the UK)? All relevant settings seem to be the wrong way around (eg. panning in the Amplifier settings, Canbus info regarding doors is inverted)?

There are two Fakra type radio antenna connectors on the head unit and a two connector cable in the car, however the Joying plug design means that only one can be connected at a time. I plugged in one and have reasonable (but not great) radio reception. Are there any other VW owners in this thread and if so, what have you done with the antenna connections? Should both be connected? I can't see how to do this without cutting off part of the plastic connector.

Is there a way to use the Golf's Aux-in port? The Joying VW wiring loom has a pair or white/red RCA connections labelled Aux-in and so I plugged these into the AV-In ports on the head unit, however I cannot find a menu option to access these. The AV-In app doesn't work (I assume because it is looking for a video input). Any ideas?

Vlaine's post above is also relevant to me - I suspect that iOS 9 is responsible for breaking a number of features in the current Joying ROM - specifically, the iPod control and AirPlay don't work for me either running iOS9.2 beta.
[MTCB Android Head Units General] joelfrojmowicz:
For question 2, check joying website (Accessories), they have an alternative cable for that!

I've a 2008 VW Passat and I'm interested too on buying this unit. Can you test the phone call functionality. Check if the other person (outside the car) if the sound is good.

Thanks!
[MTCB Android Head Units General] jbleasdale:
Thanks - You are spot on!

It looks like I need this: http://www.carjoying.com/car-access...adio-adaptor-connector-for-volkswagen-vw.html

But I currently have: http://www.carjoying.com/car-access...adio-adaptor-connector-for-volkswagen-vw.html

Will try a phone call this evening and report back.

Go to Factory settings, code is 126, change the rudder setting to configure it for right hand drive.
[MTCB Android Head Units General] jbleasdale:
Thanks! I had looked through that menu, but didn't equate "rudder" with RHD :)
[MTCB Android Head Units General] vch88:
Thank u [MENTION=4964894]asdrewq[/MENTION] for the images.

One question.. could you confirm me that the cap that you removed is the one identified by C102 near to BT module ? Like it is indicated in this post http://xdaforums.com/showpost.php?p=57982083&postcount=9

Thank you in advance!

max MicroSD?

Hi Guys!

1.Has anyone tried using a 32gb+ microSD card with this unit? I know, specs says max 32gb, but I'm wondering, maybe 64gb will work.

2. I have installed an amplifier and sub to the HU's sub output. Can I adjust the sub level or anything, or its just the EQ sliders?

Thanks!
[MTCB Android Head Units General] dark alex:
Sorry for this I moved this thread again on my own behalf because it is general discussion about this device and not Q&A.

Guess I didn't look at it exactly when initially moving from Android Auto to MTCB

But please note and know that Joying (Joyous) units are MTCB-Units and therefore discussions made here also apply to any other MTCB-Units and vice versa.

I hope this thread will not grow into a general discussion thread about MTCB-Units (or Joyous) as the old big one did :)
[MTCB Android Head Units General] jbleasdale:
I am using a 64GB card with no issues.
[MTCB Android Head Units General] Lugi01:
Which unit do you have exactly? Anyway, I guess almost all of them is the same inside. :)
[MTCB Android Head Units General] dark alex:
You are perfectly right. Even othe rmanufacturers are nearly identical designed. There are slight differences but you could also flash Klyde Firmware (but NOT MCU!) without issues :)

Just read around a bit here (I mean the section, not the thread) it's amazing what you can do :)
[MTCB Android Head Units General] Lugi01:
Thank you, I will read around! :)

Am I mistaking, if I say there is no possibility to adjust high pass filter and/or low pass filter on any of these android devices? On windows environment it can be easily done.
[MTCB Android Head Units General] dark alex:
Yes and no. There is a modded MCU by darkleo and kamarai (or similar) available. They did it.

Also there is a mod available in MTCB Hardware Development which allows you to change that on your own but there is some soldering required.

Furthermore if you know how and where you could also mod the MCU yourself. Just have a look. I would preferr the HW-Mod btw... It's the most flexible one.
[MTCB Android Head Units General] stebbo69:

[MTCB Android Head Units General] joelfrojmowicz:
Hi, have you tried the phone call quality yet?
[MTCB Android Head Units General] jbleasdale:
Yes, just tried it this evening and all worked fine using the built-in mic.

I spoke with my wife for 5 mins or so and did not mention that I had changed the head unit. The call was clear throughout and when I asked her afterwards, she confirmed that it was no different to when calling using the stock VW Bluetooth.

For reference, I bought this model: http://www.ebay.co.uk/itm/271970019050
[MTCB Android Head Units General] tmiller101:
I do not have a sub installed so I can not confirm this. However I have read that adjusting the system audio from within the factory setting adjusts the output of the amp out jack. Of course if you adjust anything in the factory settings menu if requires a reboot before the new settings take affect. So probably not the answer you were looking for.
[MTCB Android Head Units General] Sasha0574:
Doesn't surprise me... "they don't make them like they used to" is not just an empty saying...

---------- Post added at 10:27 AM ---------- Previous post was at 10:12 AM ----------

I would still like to point out that there is evidence that Joying is not a plain old reseller of Joyous, but they are in fact a registered trade mark of Joyous Electronics Ltd., most likely a brand name under which Joyous sells their dash units, since they probably manufacture other gadgets aswell. I found the patent they registered in the US while searching around on Google. So it would pretty much be misleading to place them in the same basket with sellers like Winlink or the likes of it. Trust me, I've been there. My first JY was bought from Winlink and it turned into a disaster. They have no idea what they are selling, their product support is close to none, and so on...
[MTCB Android Head Units General] dark alex:
Just a little OT:

What about creating a thread with Manufacturer - reseller links?

I think into this direction:

Manufacturer XY

Known resellers: Reseller1, Reseller2

Official Trademarks: NameXY

If someone would create such a thread in general and maintain it probably we could even stick that as that reseller-manufacturer thing often misleads people a bit
[MTCB Android Head Units General] Sasha0574:
Excellent idea, a thread/Wiki about manufacturers, resellers, re-reseller, and impressions about them as product and service providers. Not technical, just plain experience with X and Y brand/store.
[MTCB Android Head Units General] dark alex:
I would leave experience out of the OP and just put facts in it. Users could then post their personal experience as answers. one could then search the thread for his/her reseller to find information.
[MTCB Android Head Units General] Sasha0574:
Agreed. Experiences as replies, and facts filtered and retained in the "sticky" part.

Hi everyone,

Is just me or carjoying site is charging more today (black friday) then it was 2 days ago??

I was going to buy the head unit from EU warehouse but now (even with black friday discount) the unit costs more!!

Microsd

Hí Guys!

Today i bought the 64gb microsd (kingston). The

problem is, as soon as i insert -it into the slot, the unit says i can safely remove the card?! What could be the problem?

Edit: maybe the card is ntfs, i check it at home.
[MTCB Android Head Units General] SilverS4sAreFaster:
I did the same thing today, just erase the card with the unit in Settings > Storage

My problem is despite the fact that my unit literally has 3/4 of a TB of storage right now I can't install Sygic or Netflix or a better Dashcam software.... says insufficient storage.

I just got a 2nd one of these for a buddy 2 weeks ago for $250 with the ISO harness that fits his 04 GTO (though not listed this way of course) Even came with the Dashcam and the back up camera... Wish I'd paid that for mine...

Has anyone figured out to install an aux port to the joying headunits? I thought that just installing an rca to aux cable to the rca input ports would work but can't get anything to play from the aux port. Do I need to launch a specific app?
[MTCB Android Head Units General] jbleasdale:
Have you tried the built-in app "AV-In"?
[MTCB Android Head Units General] tospace2006:
Ya i have, I just get this error sign. Have you had success?
[MTCB Android Head Units General] jbleasdale:
No, I get the same error too. Possibly Joying also expect a video signal too before this will work?
[MTCB Android Head Units General] stebbo69:
In people's experience, are the car-specific Joying units supposed to fit in the existing carrier frame, or is it just that the front panel fits the slot? Are custom frames required?
[MTCB Android Head Units General] Kompster:
I just installed one of these units a couple days ago. I'd bought a harness and dash kit that were supposed to fit my vehicle, the dash kit fit the vehicle but not the unit. Instead of using the face of the dash kit I opted to just use the mounting side brackets and was able to secure the unit in the dashboard and used the frame included with the unit instead of the dash kit face. It fits nearly perfect just like that. The harness didn't fit my vehicle either, I ended up just wiring it in manually and storing the stock harness with the stock radio.

To answer your question more clearly, you'll want to have something to mount the unit in place, at the very least just side brackets.

I'm running an external amplifier and subs. You can adjust equalizer settings through the unit but you'll most likely have to adjust sub levels manually through the amplifier.
[MTCB Android Head Units General] stebbo69:
That sounds like you bought the dash kit and harness from someone other than Joying, right? If so, I would expect exactly what you saw - the wiring harness and dash kit to fit your vehicle but not to fit the Joying.

I however bought the BMW 5 series E-39 Joying - which says "If your BMW E39 5 Series or E53 X5. Joying head unit can fit and works on your car perfectly".

I wasn't planning on getting a custom frame made.

I did email carjoying attaching photos showing my head-unit slotted in 3/4 of the way, showing how the front panel (although correctly sized) won't fit in the hole in the dashboard because the DIN slot is about 1/2" low.

But Rambo replied with a video on showing just how to remove the existing radio (which of course my photos showed I'd already done). The video however didn't continue on to remove the frame.

He also sent a photo of an existing customer's unit installed with the same car as proof that it fits, but I couldn't tell from that if a new frame was required. And then advice to see a professional installer.
