:D since one week i'm the happy user of this fantastical unit. RK3188 Quad core , 1024 x 600, 16 GB

Not mounted in car, for this time, next week, but i have upgraded 2 times firmware :D thank's Joying for your customers following.

Ultra responsive screen, excellent light quality and resolution, very ergonomic usage. It's the better unit i've never had.... :cool:

Only a little regret, the cap over the SD cards slot seem fragile made with cheap plastic... and it's the only place where i have problem for insert or extract cards because need using a sort of needle for this, too small place.

But without these little default, it's the perfect unit for me...

Continue to support your customers by regular upgrades ( Lollipop ? ;))

THANKS JOYING

Interesting, is it in the future possible to update the cpu,memory and storage, if you take out the soc from the motherboard?
[MTCB Android Head Units General] nixfu:
Yeah I have noticed the same thing. the door/cap is poorly designed. you kinda have to play with it to get it to close and go back flush again with the other buttons. I also that that is quite possibly my biggest issue so far with the unit.

I plan on just putting a 64GB SD card in there and leaving it, and transferring stuff via wifi onto it and never having to insert/remove it again. But, if you were planning on removing the microSD all the time I would guess it would not last very long before breaking.

If you want to do this sort of thing, I would recommend instead switching to a USB stick and plugging/unplugging it into one of the USB ports instead and leave the SD card(S) more or less permanently installed.

I did some power usage measurements on the bench today. I did the tests with a HP Agilent programmable power supply at 12V.

FULLY RUNNING: It uses about 1.2 Amps when it is fully up and running with bluetooth and wifi turned on.

SLEEPING: when the ACC power is turned off, it goes into a lower power mode and waits for the time (30sec-XXmins+) set in settings before fully shutting down. If the ACC is turned back on in that time, it comes instantly back on. In this state it pulls about 500 milliamps or so.

OFF: when fully off, it will draw about 4-5 milliamps from the battery which is quite low and makes me not worry about it draining the battery

I am just about ready to do the install into the vehicle. I did a few mods to the unit first.

Doing some testing on the bench proved that even though it seems to be a slightly different design, this unit also has the poor microphone audio quality of other HuiFei units when operating hands free bluetooth calling. There was quite a bit of noise/humming etc using the built in mic on the front panel. The external mic jack was a little better and had a little less noise but it still was not great. So I went ahead and did the mod everyone was doing to their HuiFei units to connect directly to the mic input on the bluetooth card.

On this unit, the board layout does not have a simple capacitor you can unsolder to disconnect it from the built in mic inputs. It seems to have a trace that goes from the bluetooth card directly to the front panel ribbon cable. I didn't want to trace it up onto that board so I decided to simply use a razor blade and cut the trace on the board (see picture below) which comes from the 4th pin on the bluetooth board connector (mic+). It looks messier than it really is because you have to first scrape through the solder mask etc. and it gets all scratched up in the process. I could see what I was doing better on the bench under magnification though so I know I did it correctly..

[IMG="cuttrace"]http://i.imgur.com/nO1XKnJ.png[/IMG]

I then cut the existing mic cable plugged into the board and soldered it directly to the MIC+ and SGND pins on the bluetooth card.

[MTCB Android Head Units General] nixfu:
I also decided to change the improvised wifi antenna which was on the unit that really was just a section of exposed coax, into being an actual RP-SMA jack on the back which I could then attach any wifi antenna. For now I used the antenna from an old wifi router I had in my junk box, I am actually considering adding an external wifi antenna on the outside of the car such as one of these. I imagine that would be a huge range booster.

Stock recovery

Hello everyone.

I have the RK3066 wich i installed twrp on cuz i though i had to use it to be able to flash roms but that is not the case. now i wanna flash the original firmware back but i didnt save it before.

can anyone save the stock recovery and upload it please ? it can be done with flashify app on the play store

you just need to root the device ( o to Settings->Factory Settings, and enter *#hct#root# as the password, it enables root on the device ), then install flashify and choose backup recovery

thanks in advance, i really need it
[MTCB Android Head Units General] skange01:
:) Maybe it's me, but I still don't see the pictures :)
[MTCB Android Head Units General] TieNN89:
Your pics aren't working for me

It ended up cutting the pin that goes from module to board

But the trace you're referring to doesn't actually go to that ribbon cable closest to the module.

It actually runs across the front (infront of the ribbon cables) then over to the external mic plug somewhere over there
[MTCB Android Head Units General] weapons777:
Hey [MENTION=5162717]nixfu[/MENTION]. Still unable to see the pictures.

I am really interested in checking them out.

Thanks for taking the time to post them.
[MTCB Android Head Units General] fabien_m2002:
i own this unit, close to perfect :)

i bought this one from Germany to speed up delivery and avoid taxes (it takes 3 days to arrive to me in France):

joying-europe-eu-warehouse-2015-latest-aftermarket-7-inch-2-double-din-1024-600-in-dash-car-stereo-android-4-4-4-kitkat-quad-core-head-unit-autoradio-16-gb-memory-touch-screen-airplay-gps-navigation-radio-audio-system-support

I chose this one because of

- 7 inch

- 4 core RK3188

- Android 4.4 and future 5

- Physical buttons

- ISO provided

- very regularly firmware releases

- more powerful model for a veru correct price to compare to major brands of market

- The technician/vendor Rambo is very communicative/avalaible, even after buying

It replaces a Parrot smart, which is a very good unit too but stayed at android 2.2 :(

I approve all previous comments on this unit, very high end finished except plastic cache of micro-SD cards which looks cheap.

Unit starts in 15 seconds, good suprise. Interface is very reactive and i can install what i want. Sound is good and radio reception too.

My concerns are:

- no tethering bluetooth 4G sharing with my mobile phone, only wifi hotspot works. It's a pitty because it drains battery of my phone.

- no vocal command for calling, searching music

- only GPS app could be changed as default, no music app neither radio app

- it's not very easy to tap on the letters located in the border because of the physical extended frame in high

- no favorites feature for radio channels

I have read that i can deblock some thing with a rooted firm, xposed frameword and mode MTCxposed. I have to check it out.

Anyway, quality/price surpasses theses concerns to me and i am very happy with this buy.

i would like to buy the Model JY-UQ124 = RK3188 Quad Core, 16 GB Flash, 1024*600 Screen,the Specs looks good!

I have now a AN-21U in my Car installd with the newest Redmod but the Boottime and the Mic Gain sucks!

-how long does the boottime from the Carjoing model take and how is the quality of the Microphone?

-I read something about a Mic Mod, which is in the model also necessary and if so, there is a manual for the Mic Mod?

-can I use the Malaysk Rom for the Radio?

Is it worth it to change the model at all?:confused:

thx
[MTCB Android Head Units General] fabien_m2002:
Hello,

i have same model and like i wrote in my previous post, it takes 15s to boot.

Ext Mic quality is good (don't test internal mic). I put it in front of mine and can dial without concern. My interlocutors don't complain.
[MTCB Android Head Units General] Sasha0574:
1024x600 RK3188 still wears august timestamps... didn't install, rather wait for some other MCU and, if I have the time, I'll go for Malaysk's rom. Realy better than stock.
[MTCB Android Head Units General] SilverS4sAreFaster:
Not for my E36. It's a double din opening just very shallow.

Mine is similar to this.

[IMG="Console"]http://www.pelicanparts.com/techarticles/Henning/E36-Climate/2_Console.jpg[/IMG]

Some people move the climate control down but I don't like the idea of having to mold the corners of it in. It's easier to put some oil pressure/temp and other gauges in the top where the radio is and mount an Android unit in the bottom but making the unit fit is still an issue.
[MTCB Android Head Units General] asdrewq:
I have my 64gb microsd installed now & its working great. I had to format it on the PC to fat32 before it would work.

The microsd socket & cover are not great quality. Be careful when removing a card as mine got stuck. It needed to be pushed in & to the left slightly to remove.

If your microsd plastic cover won't close easily, you need to straighten the plastic bit which ties it to the unit. I used a small pair of pliers to do this.
[MTCB Android Head Units General] some_postman:
Hi all, I just ordered the quad-core 1024x600 version (I can't post the link here yet, but it looks like the unit on the first post) I've been trying to do some reading on things, but some of the threads are truly gigantic!

Is the Malaysk custom ROM way better than stock? Should I change to that before I install it?

Did people here install the head unit themselves or get someone local to do the install?

What is the backing camera and external mic they provide like? Decent enough quality or do they need to be upgraded from the 'freebies'?

Thanks for your help... I'm looking forward to having it running!
[MTCB Android Head Units General] Telemachus:
The ribbon cables don't give much wiggle room, but they face COULD be angled differently from the body of the radio. It wouldn't be too difficult to fashion a holder that would keep the face in the right spot, and still protect the ribbon cables.
[MTCB Android Head Units General] Hisma:
Hey Guys,

I just installed a JY-UQ124 in my car. I have most features working, but I can't get steering wheel controls working. I am 100% sure I have the correct steering wheel wires going to key 1 & key 2 (order doesn't matter right?), because I verified against my car wiring diagrams, and I checked resistance with a multimeter and I see it change when I press my steering wheel buttons.

The HU doesn't recognize any key presses though. Do you guys have any tips? Should I buy a PAC? Any software settings I can change to see if it will help recognize my commands? Please help!

---------- Post added at 11:39 PM ---------- Previous post was at 11:33 PM ----------

I can only comment on install. I bought the ISO model (non vehicle-specific) and it's kind of a pain to install. It does NOT conform to exact double-din size standards, so I had to jerry rig my dash kit to get it to fit in my car correctly. Pretty annoying. But the wiring isn't too bad, I cut the harness & soldered the wires to my aftermarket harness that fits specific to my vehicle. Everything went smoothly. I did the BT audio mod on the first page too, it wasn't too bad but I wouldn't recommend unless you are comfortable soldering & tinkering... can easily screw something up there if you're not too careful.

I can also comment on the external mic. It's good quality. People can hear me just fine, but again I did the mod so can't speak for stock quality. My car already had a backup cam so I will use that. Haven't installed malaysk yet but I might if I experience any instability. Stock runs pretty damn smooth tho.

Overall very happy except for the crappy fit.
[MTCB Android Head Units General] Sasha0574:
I see your point... and there is no room for expanding that space back there? Maybe some cutting? I don't think it's easier to cut the unit itself and doubt the chinese make them with the mainboard at an angle....
[MTCB Android Head Units General] Schorsch1976:
Hi All,

would like also buy 8813H or 9813H for VW Passat. I saw bluetooth handfree call is not fine. How about quality of radio signal by using a divesity adapter? Could someone tell what really Radio Chip is on board? Joying sent screenshot from factory settings and this tell it is TDA7786. But this Chip not exist normally. STM produce the TDA7706 and this one is at the pumpkin which should have same hardware. Is it maybe the TDA7706 too at Joying 8813H and 9813H, but only wrong displayed at factory settings? Could someone post a picture what really is on board? Thanks very much
[MTCB Android Head Units General] Sasha0574:
Truth is that in fact only God knows who and where makes all those components. It can say anything you want on them. Even the "manufacturers" that present their "factories" will show you images of a place where different components (mainboards, screens, wires, etc..) are assembled, but the DO NOT PRODUCE them. They only assemble them to finite products. So what did those who make the mainboards put on them is anybodys guess... It's like turkish clothes... they will put on them whatever label you want if that makes you happy, but what are they in fact? Some you guess, some you don't...

Display quality?

Hello all!

Im about to buy this product from Aliexpress (Quad-core-Universal-Double-2-Din-Android-4-4-Car-DVD-NO-GPS-Navigation-Wifi-3G). It looks kind of good, but I just watched a youtube video of it. I hope it's just the recording quality, but the screen looks as if it has grid or stripes in it. Here is what Im talking about: Actually I cant post links yet. So, is the display clean enough? Seek to 7:05. Is it like this for real? Thanks

Lugi
[MTCB Android Head Units General] Sasha0574:
Just make sure the screen is 1024x600 and the picture will be ok (unless it's broken:D) What worries me is what comes after NO... no GPS, Navigation, Wifi, 3G?
[MTCB Android Head Units General] Hisma:
experiencing some other issues. I put google now & google maps in the car. For some reason when I try to do a voice command, it does one of 3 things -

1. says "sending voice command to phone" This happens when I have my phone paired w/ BT, but not always

2. As soon as I press the mic button, the google app crashes

3. It says "please try again" in an endless loop

Any tips on getting voice control to work consistently? The only way I seem to get voice controls to work is if I go directly to the voice search app. But voice commands inside of google now or google maps don't work.
[MTCB Android Head Units General] Lugi01:
Thanks for the answer! Of course it has GPS, no DVD was meant. GPS and wifi is built in, 3G is not necessary to me, since I share internet from Cellphone through Wifi.
[MTCB Android Head Units General] Sasha0574:
Ah ok... DVD is anyway a thing of the past... mine has it but never used it...
[MTCB Android Head Units General] Lugi01:
My only concern was the display quality. But you say its ok. I cant insert links yet, but i think all Joying 1024x600 quad core tablet has the same panel. Btw, I have a wayteq 1024x600 handy tablet, so they should be very similar regarding to the screen. Doesnt -it? I would like to make the wayteq disappear from the windshield, and i think this headunit couldn do the job.:)
[MTCB Android Head Units General] Sasha0574:
My guess is pretty much any gizmo that comes from China has the screen made in the same place. Namely this place: http://www.hannstar.com/Common.aspx?mid=177&tmid=3&modid=4

phone mirroring app

I promise I searched this post as well as the other humongous main post but could not find the answer. Just bought a Joying RK3188 unit. Love it. But [MENTION=3590033]Malaysk[/MENTION] rooted ROM looks awesome. In the stock unit I really love and use a lot the phone mirroring easy connect app that allows mutual control of android phone from head unit touchscreen. It works great and I use it a lot. I also like it as a way to futureproof the unit since my phone will keep up with updates and they can be mirrored and controlled from the headunit. I have not seen any mention of whether this function will still work with Malaysk ROM. Caryjoying customer support is warning me that I will lose this function if I deviate from stock unrooted factory ROM. Just want to know from folks who have the Malaysk ROM and use the mirroring function. Thanks in advance.
[MTCB Android Head Units General] HenrikH29:
Be aware that even if you upgrade the firmware with Joyings own upgrades you also loose the mirroring capability, so it's not just at problem with non-factory roms. However i cannot see what you would want to mirror to the head unit ? Instead i would rather install the program, that i might want to mirror, directly on the HU (navigation, music-streaming or whatever).

I got some useful updates from Joying earlier this week when enquiring about Android 5 support:

1. Joying

do not

plan to offer an Android 5 update for their existing head units

2. Joying will launch new head units with Android 5 by the end of this year

3. They have a new 10.1" head unit coming out in mid-November.
[MTCB Android Head Units General] Sasha0574:
Now you see it, now you don't, as they say... Lucky enough for the owners of this kind of toy, there is always Malaysk who might have a say in this...
[MTCB Android Head Units General] jbleasdale:
Is the Malaysk ROM built on Lollipop? Or is it planned to be?
[MTCB Android Head Units General] Sasha0574:
Malaysk mods the existing ROMs. And so far the chinese haven't released a Lollipop... at least that I know of...
[MTCB Android Head Units General] 2safe4you:
Hmmmm.......

i become this Information for 9 Days:

Android 5 for the RK3188 1024x600 is still developing, it may be can be released at the end of the year.

But I have no idea of the actual date.

Now our all products is Android 4.4.4.
[MTCB Android Head Units General] jbleasdale:
I suppose this may be a question of interpretation. The actual message I received states:

This may mean that existing units cannot upgrade ever, or it may mean that new units with Android 5 may come along first and upgrades later.

Hello , Can anybody comment on the latest official firmware released on the 16th of October (Changes or change log ) , I have recently installed mine and has the August version.

So far i am very happy with the system , Only had one glitch where the IGO app decided to forget all my settings and turn back on all those annoying warning sounds.

I fitted to a Triton MY14 GLX using Holden Harness ( for some dumb reason GLX harness is different to all the others)

Hey there,

I just received my RK3188 800x480 yesterday and have been searching like a madman to get the steering wheel controls working in my 2015 Jeep Wrangler.

I haven't had much luck searching, but perhaps my google-fu is lacking. I decided to just give a shot with what I had on hand and happily I had great success.

For my set up I used a Maestro RR decoder with an ads-hrn(sr)-chr01 harness. I had the Maestro RR flashed to work with a Pioneer Appradio 2. once the speaker and power were connected I simply connected the Key 1 wire from my Joying head unit to the Blue wire with the Yellow stripe (the one on the blue plug which also has the 3.5mm plug on it.) and went into settings on the head unit. I was able to program the buttons from there. I hope this info can save someone else the frustration that I went through.
[MTCB Android Head Units General] sniktaw:
I found it to be poor. Rambo suggested insulating the connector with electrical tape and also not fully inserting the connector into the unit. Has made some difference, I now get RDS. Still waiting for my antenna amplifier to arrive and will follow up with a post when fitted.

Installed the JY-UQ128 into my Scion Xb

Well I finally installed the UQ128 last night into my 2005 Scion Xb and first impressions is it's okay not great but okay. The radio reception is about as good as a Pioneer Premier head unit in my car just slightly weaker. The amp is capable of producing sound levels more than loud enough to hurt your ears but something is off. The sound quality is lacking, it is to bright or tinny, turning loudness on and tweaking the EQ has made it better but I'll have to tweak the EQ more to get the sound quality to more of my taste. The touchscreen is bright enough so far and responds fairly well but from time to time won't register a touch. The system appears to be quick it starts apps and switches between apps just about as quickly as my Note 4. The unit fits into my dash but just barely I will have to modify the side pieces of the install kit to make the installation look professional. The GPS antenna wire could have been a few feet longer, it limits the placement options, but it still works great and was able to pickup a GPS signal quickly even inside my garage which is a tuck under. I did notice a bit of background hissing during iGO sounds but I didn't have any music playing at the time, I'll have to listen close when music is playing, either way it wasn't loud enough to be deal breaker. I do wish there was a way to change the navigation voice but I deal with it for now.

Overall I like the UQ128. However if there was a unit utilizing a touchscreen with a standard tablet resolution, a more user configurable launcher, and an amp and radio in which higher end components were used I would switch in a heartbeat and even spend a bit more money on it.
[MTCB Android Head Units General] Sasha0574:
Tweaking the native EQ and fiddling with the stock UI will only get you so far... You want more option and qualitywise... go for Poweramp or Jet Audio for sound and Next or Apex as default launchers.
