Look under factory settings there is a RGB setting that sometimes gets switched over to a single color. Switch it back to RGB and the elements menu returns.

An update on a discussion I've seen on XDA, namely that "Joying" are actualy resellers, and "Joyous" are actualy the manufacturers of our units... Since I had the missfortune of my unit breaking down on me, and Rambo of carjoying promptly sent the part they consider broke down, guess what is stated on the parcel "Sender".... JOYOUS! That only confirms some documents I found online some time ago, in which is said that "Joying" is a registered trademark of the producer "Joyous Electronics Ltd."... so these guys are not just some store reselling the units, they are actualy part of the play... some people may find the information useful...

The orange wire connects to the "Reverse light" 12 V line, so when car/truck is place in reverse the camera works. In my Toyota Tacoma, there was a connection for the reverse sensor under the dash.

Gentlemen, an information update regarding the Android update:D and I quote from Rambo's message:

"We will update android 5.1 version, but we just developing it and doesn't test it.

We will do it and let the Joying customers know."

Guess that should end the talks regarding "will there be, will there not be an update";)

BT phonebook

Hello Guys!

I'm having trouble using the phonebook on the headunit. The phone is correctly connected, I can use it with no problem. But when I try to download the phonebook from my phone (Honor 6), the headunit keeps loading but nothing happens. At first, it requested permission to use the phonebook, and I allowed it. I store my contacts in Gmail, if it counts. Did anyone has similar problems? Thanks!

Just got one of these head units, and was wanting to update to Malaysk's rom, but after reading most of this thread I couldn't find the answers to a few questions I had.

potato camera image from the settings screen:

goo.gl/photos/NMapGJ9Sd7tsLibj8

1. I can't tell if my unit is using 1024x600 screen or not. I took a screenshot and it did have this resolution, but after the warning text "Will brick your device", i'm being overly cautious before flashing.?

2. Assuming it is 1024x600, can I apply the Malaysk rom from this location: huifei.fs-fileserver.de/content/firmware/KK 4.4.4 MALAYSK Custom ROMS/Malaysk Quadcore RK3188/1024x600/ ?

3. Do I have to update my MCU before I update the rom, or can I leave the MCU at the current build? If so, I couldn't find any MCU firmware around, I could only find firmware for the other Hui Fei units, but not a JY unit.

Any help is greatly appreciated.
[MTCB Android Head Units General] Justsaye:
It looks like it is the 1024x600 screen for a VW, model JY-VQ127. I don't think they make a 800x480 with the usb port on the front for the VW.

You can flash the 1024x600 MALAYSK Custom ROMS. If your images look cut off after you boot then try the 800x480. This should not brick you unit.

Don't update the MCU firmware. Your using the latest (check this post for the newest). Flashing the wrong MCU firmware will brick the unit.
[MTCB Android Head Units General] Syphe:
Thanks, I got it all updated, did a factory reset again and everything seems to be working, dark outside now though so have to have another play tomorrow :)

I fixed the 'absolutely no microphone sound during bluetooth call' issue - it appears the unit didn't work with the JVC mic I had already wired into my car. I tried it with the microphone provided and it worked (albeit with interference, which can be solved)

My jvc mic has a mono jack, the included microphone has a stereo jack. Is the mic input on these units not a conventional mono type? That's the only reason I can think of as to why it didn't work.
[MTCB Android Head Units General] GAF70:
When i installed my Joying HU i tried a Parrot mic (thinking it would be better quality) and didn't work at all.

I had to connect the included mic, and it's working quite good. So yes, probably different type.
[MTCB Android Head Units General] quikshifter:
Hi. I had an issue with this unit where the screen became blank and would not turn on. I took the screen off and checked all cables and now the screen works however now i get no sound. Which one is the sound cable?
[MTCB Android Head Units General] tmiller101:
Has anyone experienced a problem with the backup camera picture twisted a little?

The picture is like 10 degree counterclockwise from level. Any ideas on a fix? The camera snaps into the spot where the plate lite goes, so its pretty stable and can't be physically moved.
[MTCB Android Head Units General] asdrewq:
This will be an issue with the camera, it will need rotating in its housing. I bought a cheap one to experiment with (ball/socket type) & you could unscrew the housing & rotate the camera 'ball'.

---------- Post added at 12:10 PM ---------- Previous post was at 12:07 PM ----------

I'll look into this when I next have the HU out of the car. The mic input is a simple 2 wire so I think the external jack plug might use the stereo ring for the mic input. I think the only reason you couldn't get any mic to work is if it's a powered type & there is no voltage on the mic input.
[MTCB Android Head Units General] Syphe:
I'm having an issue with Sygic, I can't install from the Play store, so followed the instructions on the Hui Fei thread, however once I have installed, the app just starts up with a message "SD Card is missing. Please check".

I've tried a factory reset (this is all on malaysk rom), and same thing again, play store won't let me install it because it doesn't think I have an sd card.

This time I tried installing on my phone (from play store), and grabbing the .apk from /data/ on my phone, then installing this on my HU. Installs fine, but I get the same "SD Card is missing..." error.

Anyone have a similar problem?
[MTCB Android Head Units General] mrr19121970:
I have a quad core joying hu for Ford focus installed (2010 model oval form). The button lights don't stay on (or come on with the headlights). The buttons light during startup and during setting colour changes and then go off again. I have canbus installed and red acc wire disconnected. In settings I have no canbus, the steering wheel buttons work ok. I have tried removing then canbus and connecting acc wire. This didn't help.

Any other ideas ??

Update:

I measured the ILL wire with a multimeter. It has 0v when lights are off and 2v when the lights are on. I guess the head unit needs 12v ?? According to this http://www.carjoying.com/Joying-blog/9.html I should bridge ACC and ILL, but then I will loose auto dimming at night ???
[MTCB Android Head Units General] Sasha0574:
Let me see if I understood.. you want the unit lights to remain constantly on, wether you have the car lights on or off, wether it's day or night? That it?
[MTCB Android Head Units General] mrr19121970:
No. I want the back lights of the buttons to come on when it's night ie my lights are on. I have now resolved this, I was thinking my ILL wire carrying 2 volts was wrong so i checked Google. People referred to it as the "dimmer wire", then the penny dropped. Under my light switch I have a dimmer wheel for the dashboard illumination. It is set to the lowest setting. When I crank it up my dashboard lights are too bright for me, but the HU back lights come on fine. I guess the low threshold in th canbus is higher than 2 volt.

I guess there is no way for me to alter this?
[MTCB Android Head Units General] Sasha0574:
Update on my HU

Gentlemen, an update regarding my HU. Rambo sent the coreboard and as soon as I had it replaced, it worked like a charm. As it appears, at least from what I talked to him, those coreboards are (were) having a bug of which they were very well aware and by the time they sent me the new one, Rambo claims they got it fixed. So if all of a sudden you screen goes black and you loose all touch capabilities, and the unit doesn't even turn off any more, it's the coreboard gentlemen and you shoud probably get in touch with Rambo pronto to have it exchanged.

A minor "byproduct" detail... dunno if I was too sleepy, or my HU started even sounding better on the native player after changing the board... can't say for sure...

---------- Post added at 02:59 PM ---------- Previous post was at 02:55 PM ----------

Ah yes... the only way to get more brightness to that is to fiddle with the color... enable the RGB in the factory settings and play a little with the color, make it a bit brighter... I did that to match the true color on my Octavia dash... the "standard" green was darker than the original green on the dash so I just messed with the RGB until I got them to match.
[MTCB Android Head Units General] Syphe:
Fixed this, for anyone else with a similar problem, it was because internal_sd could not be mounted. In Settings->Storage, if you find the internal_sd sd card and clicking on Mount doesn't do anyting, erase it, and it should init to 11GB+ (depending on rom). All of a sudden Sygic would work, and the internal_sd started to fill with the usual Android stuff (DCIM, Movies, Android folders etc.)
[MTCB Android Head Units General] mrr19121970:
26 hours after installing my joying HU my car battery is flat. The ACC wires are disconnected and the canbus is connected. Anyone have any clues or tips for me?
[MTCB Android Head Units General] Sasha0574:
More details? What car? And why exactly did you disconnect the acc?

Sorry... gottcha... Ford Focus... could you be having the problem that some VAG older models have? An uncompatible CAN? On some older VAGs, the can is draining the battery like crazy if you switch from the factory radio to some after-market one...
[MTCB Android Head Units General] mrr19121970:
My car is a 2010 Ford Focus 1.6 (8566 ABO / FORD DA3). The instructions provided by carjoying say leave the red ACC disconnected and connect the canbus decoder. If the unit does not power up then disconnect the canbus decoder and join the red ACC wire. This information is repeated in their blog here

I suspect the fastest workaround is to disconnect the canbus decoder and connect the red ACC wires. This means that my steering wheel controls won't work, but my car will start next morning.

Further info, the carjoying android HU is my 2nd try. Previously I installed a WinCE ersin model which also drained my battery - so I sent it back as 'faultly'
[MTCB Android Head Units General] Sasha0574:
2010... before sending the unit back again as faulty, try to see if you can find a forum specialised in Fords. There you might get a clue as if the problem isn't of the nature I told you about. I have heard some rumors about the Mondeo being a tricky one when it comes to these units, but dunno 'bout the Focus... try your first clue on those forums. Also, you might want to check with your car service and see if the CAN connection isn't to blame for that and if you can't do a software update or a CAN upgrade alltogether ( I know that was the solution for the VAG cars that even had trouble with the "OEM" RNS510). Also... what amperage exactly does your battery have? These units tipicaly need some juice to keep some stuff working even when they are shut down... mine is 77Ah and I never noticed power drainage on any of the three "Chinese" I had on it, one WinCE and two Androids...
[MTCB Android Head Units General] mrr19121970:
I have to check the battery. It is the original (date manufactured 2008) battery, car is 1st registered May 2010. I've already ordered the biggest replacement I could find at 61aH (exide ea621). I guess in the short term the only option for me is to remove the canbus decoder and live without steering wheel controls. This is better than not being able to start the car on a cold wet night.

update

My ELM327 can't be detected by "Torque" (bluetooth pairing is no issue), is this also a sign of a canbus issue?
[MTCB Android Head Units General] Sasha0574:
First of all... oh yeah, you are right about that battery needing to be changed, and pronto! I'd recommend a Bosch or a Varta Silver type at the least... Short term CAN disconnect, right again, though as far as I know, it will cut more than the buttons... That is how the unit "smells" the rear view functions, as in camera, parking assist, the parking sensors, brake... and quite a few more... but way better to disconnect it than look at a dead car in the cold morning. In the meantime, make some inquiries about the potential CAN drainage and see if it's only a weak battery or there is more to it...

"update reply":).... most likely not, and is due most likely to a bad ELM clone... CAN has nothing to do with it... also, see on the general HuiFei thread, there are plenty of guys complaining about OBD and some solutions aswell...
[MTCB Android Head Units General] mrr19121970:
In a German forum there are suggestions that the canbus is not sleeping as it is looking for the factory radio. I can't find any references in English, anyone ever hear of this before?
[MTCB Android Head Units General] 2safe4you:
Have you the link to the german forum?

[MTCB Android Head Units General] tmiller101:
Does your focus have a factory Amp?
[MTCB Android Head Units General] mrr19121970:
I would say no, or at least nothing that I am aware of. Previously I had the "Blaupunkt Travelpilot FX" built from new:

[IMG="Travelpilot FX"]http://lafeo.de/thumbnail.php?pic=store_uplimg/38042/288_0.jpg&w=298&sq=Y&b=N&mem=Y[/IMG]

On a side note, I set my charger overnight on the car battery. It is full this morning and the charger is delivering 0 amp to the battery - for me this is a good sign, as if the battery is not charging there is no drain currently. So I am hoping the factory battery is indeed weak and at the end of it's life.
[MTCB Android Head Units General] Sasha0574:
A 2008 62Ah battery is by now a miracle to start at all... Usualy, even top class batteries should be changed after 5 years
[MTCB Android Head Units General] mrr19121970:
Oh no, the factory fitted battery has a much lower capacity. 42aH or something from memory. Funnily enough the car won't start but radio, lights and all other electronics had no issue.
[MTCB Android Head Units General] Sasha0574:
Even worse... and the car won't start because the alternator needs much more power than the electronics... the altenator that starts the engine is the single most powerful consumer of them all. And I see the directive of mounting underpowered batteries from the factory doesn't only apply to the VAG group, it migrated to Ford aswell...
[MTCB Android Head Units General] Taomyn:
I think you mean "the starter motor" uses the most power, the alternator charges the battery.

Hi again guys. Anyone has the new joying unit that comes without a volume knob but just capacitive buttons? How responsive are they?

Thanks Sasha. Ill get it tomorrow then, as theres the aliexpress offer day tomorrow and it will be like 40€ cheaper :) btw, do u have a rear view camera? As i some of them say ntsc or pal, but being in spain i should get the pal one, ecen though i dont know if it would make a difference with an android device?
[MTCB Android Head Units General] mrr19121970:
why not direct from joying.com and take the 18% discount code JOYING?
[MTCB Android Head Units General] Sasha0574:
Got one of those too... don't even know what standard it is, ntsc and pal applied a long time ago, when screens were made out of lines. Whatever you get now is shooting its signal into a pixel generated image so it realy makes no never mind. If they have sales, get one from them, guess you can hook a discount on it aswell.
[MTCB Android Head Units General] azuman:
Well, because from aliexpress it will be like 240€ with shipping from germany, whereas in joying.com its like 290 for the same, so the difference is noticeable. As per the camera, i thought so, but just in case, as some sellers keep saying beware of ntcs / pal cameras.

Nowadays in a camera you need to be aware of it's type... namely CMOS or CCD, but of course, in these chinese made toys you have no certainty whatsoever, so it's a bit of a roulette, the view angle... as close to 170 degrees as reasonably possible... again... you see that when you get it, and third... light sensitivity... trust me, once you get hooked to parking with a camera, parking in the dark is a nightmare with a poor visibility camera... also... WATER RESISTANT! some take on water as soon as it rains... the model I saw in Joyings photos appears to be a decent one, from what I've heard... mine is a form-factor designed to fit in the trunk lights
