[MTCB Android Head Units Q&A] typos1:
Someone did say that a few pages back, but they were wrong, as I ve said quite a bit, the only differences between the dual and quad core are the SoM and some small pieces of the Android image so that it works with the quad core processor.

An SD card is an SD card, you dont need a specific one to do the updates, there may be a problem with your SD or something. I ve updated using many different SD cards and theyve all worked fine.

On the USB side, someone a few pages back said they could update from a USB stick, then they changed it and said they couldnt. If you can update the Android side from a USB stick, thats great and you may have discovered a new thing for these units.

I cant see why updating from a USB stick would be the cause of your unit's problems, but it may be worth flashing the Android side of things again from the SD card slot and seeing if that sorts them out, just in case.

Is that a JY version ? What site is it from, JY's Alibaba ?
[MTCB Android Head Units Q&A] Enc0der:
Yes, sorry I forgot to mention. It's JY.

It's from a store in aliexpress that sells them and had the JY- 8813-7 model with "Quad Core" in its title (by mistake..).

Can anyone advise what they are using for a DashCam set up? Does any USB web cam work? Which one are you guys using and also what application are you using?
[MTCB Android Head Units Q&A] corwest:
Awesome thank you. Yeah I am a little nuts. Kids came along and couldn't fit them all in the Mazda. Loved that car though, the amount of options you get for the price is unbeatable.

The static issue is there regardless of if the car is running. It's just a low level noise that stays constant as soon as the unit boots up

---------- Post added at 08:01 AM ---------- Previous post was at 07:57 AM ----------

I also wonder this. I'd love for my bluetooth music to start playing immediately when I connect the device. The way it works now I have to connect my device, hit play on the phone which starts the music but you can't hear it, then hit the bluetooth app on the device to hear the music. Then it quits if I hit back instead of home. Kinda finicky way of keeping and closing the bt app

Sorry for my english, but someone Could help me?? Thanl!!
[MTCB Android Head Units Q&A] corwest:
Could be a loose connection in the back? Did everything work without issue before the upgrade? My next guess would be some sort of corruption during the install. Or your having some memory management issues and it's causing background apps to close or behave wierd
[MTCB Android Head Units Q&A] martinblanco20:
Before upgrade do the same issue. I will check connection in the back. Maybe it could be some overheat in the unit??

Thank for help me!!
[MTCB Android Head Units Q&A] corwest:
I doubt it's a heat issue. Probably a connection issue if I had to guess

Everything seems solid. Can't seem to get xposed framework / app settings to change the dpi. Is there any other app that can do this if it's not compatible with this ROM. Get the Google app stopped working when trying to use voice search (I had that worked out with stock ROM).

Thanks for your work on this.
[MTCB Android Head Units Q&A] DJCannonball:
if it was a loose speaker-connection, it would not interfere the strange software behaviour (amplifier settings not responding)

just my opinion
[MTCB Android Head Units Q&A] corwest:
Well he wasn't real clear on what he meant by not responding. Did he mean the UI wasn't responding or he would change settings and the speakers still won't come on?

Hi All,

I have recently installed an eonon G2110 which is RK3066 with 4.2.2

TomTom is working perfect with GPS, but my iCoyote says no GPS signal.

Did someone already face this issue ? Any idea to help me ?

Thanks in advance.

[MTCB Android Head Units Q&A] corwest:
Might have to change the GPS signal source in the program's settings. There may be an internal/external toggle or something. Just a thought

Hi there,

i got an Klyde-Unit for my Kia Ceed.

Tried Coudu's 4.4.4 and Malaysk's newest rom, tried MCU Update from version 2.20 to 2.40 but it´s still not possible to sync my iphone 6-contacts via bluetooth with my unit.

Maybe someone any idea to make it work?

Thanks in advance!
[MTCB Android Head Units Q&A] agentdr8:
Should be fine. The USB 1.0 and 2.0 specs say a standard downstream port can deliver no more than 500mA of current. So if your hub has 4 ports, that should be no more than a 2A draw with all ports in use.
[MTCB Android Head Units Q&A] typos1:
Right, I guess JY are working on quad cores too then.

Not using one myself but do a thread search plenty of posts about it

Try updating your MCU, or "down" dating if that doesnt work. Also a factory reset might help.

Yeah, plenty of screen resolution and dpi apps in the Playstore.

I d say Klyde or JY are best, but I only have experience of those two, others may disagree, I d read the thread and make your own opinion.

Hmm, cant even begin to think why one GPS app would get a signal and another wouldnt, weird. You dont have an Eonon BTW, they are just resellers, to find out what unit youve got go to the "about" screen and read the first page of this thread.
[MTCB Android Head Units Q&A] clearchris:
There are resellers, but it wouldn't surprise me one bit if the manufacturers customize by reseller. So yes and no.
[MTCB Android Head Units Q&A] typos1:
Yeah youre right, they do, they add "EONON" stickers on the front for example. :)

Hi i have the android 4.2.2 and the lights on the buttons don't light up when in use only when I power on the system I can change the colour in the settings when I go to element but the light just turns off after .. is there a solution to this any1 expirienced this? Thanks
[MTCB Android Head Units Q&A] cuboy29:
I think the button lights only come on if you turn on the lights on your car (assuming you have the Illumination wire wired up).
[MTCB Android Head Units Q&A] Nicktheo49:
I think your right I was thinking that.. however it's wired because the lights come on when I go to change the colour and also power it on..... where do I wire the illuminati wire up 2 if u know ?

Cheers m8

---------- Post added at 02:27 AM ---------- Previous post was at 02:25 AM ----------

Illum wire is not wired up :/ wer do I connect it 2 :o/
[MTCB Android Head Units Q&A] clearchris:
Its actually painted on, I assumed it was going to be a sticker too. ;)

I was thinking more like tantalum / electrolytic caps, fan / no fan, dual / quad core cpu, etc.
[MTCB Android Head Units Q&A] pants001:
It would appear your button lights are not wired up.....my BMW is wired up through power harness by default.

With lights off the buttons are not lit. When i turn car lights on the button backlights come on.

(Even when i turn lights off, when changing color the buttons are illuminated for a second or two...same as what your seeing)

Interesting enough, the buttons seemed wired to the Dash lighting, not the headlights themselves.

The reason i think this is if i turn my dash lights dimmer down, from 0-50% the backlights turn off....from 50% up to full, they come back on again.
[MTCB Android Head Units Q&A] martinblanco20:
The problem is when go to amplifier setting i change diferent side, front speaker, rear speaker, driver, ect. When press diferent options dont work. If i put rear speaker dont sound, driver speaker sound very quiet. The only speaaker that works is co driver. And then when press reset button its sound all speaker ok!!!.

I tried with KLD MCU 2.16 - 2.20 - 2.21 - 2.30 and 2.40 and have the same problem in all. I tried coudu 4.4.4, oficial KLD 4.4.4 and Malaysk's.

How i do a factory reset??
[MTCB Android Head Units Q&A] corwest:
Since you have tried all that and nothing has worked, a factory reset likely won't help. I'm thinking there may be a hardware issue with your until. Maybe the internal amp is messed up some how. This one has me stumped
[MTCB Android Head Units Q&A] ga!nusha:
Not anymore. Besides, mine came in a Klyde box lol
[MTCB Android Head Units Q&A] typos1:
Lol ! :p

Pretty certain each manufacturer uses the same caps for all their products regardless of customer. I guess if someone told Klyde they wanted a fan in their units that theyd do that sort of thing. I spose you could call quad or dual core processors "customising" - but they were developing the quad cores anyway, as were KGL - they havent come about cos a supplier asked them.

---------- Post added at 11:28 AM ---------- Previous post was at 11:23 AM ----------

Its still worth trying a factory reset, it does cure a lot of things.

martinblanco, I have read of this problem with KGLs before, really cant remember what the solution was, but I would try a factory reset and I would also spend some time searching the thread to find out how the other people who had the problem sorted it out. You need to put a pin into the hole in the front.

I m trying to work out why anyone would want to use Bluetooth in this situation - if you were using your phone for Torque it would make perfect sense, but, unless you intend removing your stereo from the car and then using it to communicate with the car at up to 10m away, using Bluetooth has no advantages at all, in fact it has 2 disadvantages - its much slower to react and less secure than using the proper USB to OBD method.

I d suggest investing in a USB to OBD lead and trying again.

Cool, I was thinking of installing Ubuntu on this unit - theres a version of it specifically for the Rockchip 3066 - Pic Untu, maybe Ubuntu Touch would work as well ? Would love to see some pics your Debian install working.

Do these links help ? :

Ah, I forgot to tick root. I wil fix it in the file, but you can fix it yourself.

Open the task and tick the option "use root". It should work now.

then, to check if it works, just run the task alone (play icon at bottom left of tasks tab)

otherwise, you can try to just input the code in a shell terminal and see if it works.

if it works in the terminal, it works with tasker.

Had a look for erisineu88 and found a seller called erisin-eu. The only Audi A3 version I could find had Android 4.0.1, and no mention of mirror link. It does look like a Huifei though.

I've attached a txt file with the link
[MTCB Android Head Units Q&A] typos1:

If anything the usb ones have smaller OBD plugs cos theres no bulky Bluetooth transmitter to package, a cable is easily hidden.

if you search on eBay for erisineu88, you find erisin-eu, and the only one listed for that seller for audi a3 is the one with android 4.0.1. I've sent the seller a message asking to confirm
[MTCB Android Head Units Q&A] kaween:
Euh .... if you're refering to the txt/linkas "an android 4",I don't think it is.

I know Erisin products first hand, and the pictures of their UI are typical for their WinCE line of products.

The fact they show an OPERA browser is also typical for a WinCE unit. And I see no mention of any Android version in that link either.

As for Audi A3, I think this will be more what you're looking for :

Hi,

the thread is growing and growing. Since there start to be quite some new apps, we decided to create a file repository.

Yes. And as far as I can see, they are all dual-OS Hybrid things. Which, in lay man terms, tend to suck big time. The XDA forum is filled with people who have or had such a Hybrid/Dual OS, and whatever brand they were, the only times I read they were happy with it was when they ditched it. :angel:

Hello,

Thanks for this, but finally I found that issue is with the application itself. I have installed version 6.x , works perfect !

but with version 7.x , app got first position from GPS, then lost, no update.

So one problem solved !

Now trying to have poweramp as default music player instead of this crap default app.

Also, don't understand how works dimmer and button lightening, cause even at night, sceen is bright full :/

Thanks for your help

Kind regards.
[MTCB Android Head Units Q&A] agentdr8:
The stock dimming functionality is basically this: headlights (or running lights) on, the screen will dim to 50% of the full brightness. That's assuming your illumination wire is connected in the harness. It should also turn on all the button backlights, which aren't dimmable. There are software solutions to modify this behavior.

On some units that have a DIMM button, each button press reduces the brightness by 25%, until it cycles back around to full brightness.
[MTCB Android Head Units Q&A] iori01:
Oh thanks for those info, but this leads me to other question ^^

The main problem I have is that I don't have illumination wire on my car :/

So, would it be possible to have button backlights always on and dimming functionality based on sunset and sunrise ?

Thanks again :D

[MTCB Android Head Units Q&A] clearchris:
My headunit lost the android os today. It was stuck on the screen after the kitkat screen. Animation kept playing, but after 15 minutes it still didn't finish booting up. I haven't done anything exotic, it was a straight rooted 4.4.4 couda KLD rom with pandora and some other tame apps. The last things I installed were tasker and bluetooth auto connect by uniqtec. I don't think tasker caused it, and I use BAC on my phone, but the headunits have a different bluetooth system, so it didn't work with it.

I reflashed the ROM and it's working again. Just giving everyone a heads up in case anyone else sees this behavior.
[MTCB Android Head Units Q&A] typos1:
If you wire the illumination wire into an ignition switched power source (like directly to the red ACC wire) the lights will be always on.

Most cars have an illumination wire, ones that dont are usually CANBus cars in which case I d expect your headunit to have come with a CAN Bus adapter which will extract an illumination signal from the CAN Bus network, unless yours is a universal unit, then you may need to buy one.

---------- Post added at 08:24 PM ---------- Previous post was at 08:21 PM ----------

You do have a JY if thats what it says.

As the first page says, you can use any of the Android versions from any of the manufacturers on any unit (not quad cores units), so your unit manufacturer isnt relevant. DSA was just telling you that the pre-rooted KLD 800x480 firmware has the script you require built in.
[MTCB Android Head Units Q&A] iori01:
After deeper check, it appears that my car is providing illumination signal with CAN Bus network.

This is the transition to my next question :p

I plan to connect CAN Bus cable from my eonon to the CAN Bus cable from the car. Just 2 cable, key1 and key2.

Do you think my stereo car will be able to understand Illumination ? as well as wheel steering control (from CAN Bus) ?

sorry for all question but almost impossible to read more than 1000 pages :crying:
[MTCB Android Head Units Q&A] typos1:
You do not have an Eonon, Eonon are just re-sellers, you have a Joyous or a JY.

What do you mean by "CAN Bus cable" ? Because "key1" and "key2" are for the SWC NOT the CAN Bus, on some CAN Bus cars the CAN Bus controls the SWC, on others it does not and the SWC are resistive. Your CAN Bus adaptor may or may not have key1 and key2 wires depending on whether they are resistive or CAN Bus controlled .

If your Stereo has an illumination wire and SWC wires the then it can understand illumination and SWC !! Does your unit have a CD/DVD drive ? Do you think it can read CDs and DVDs ????!!! Silly question really :)

It IS NOT IMPOSSIBLE to read more than 1000 pages, it just takes time, a lot of people cannot be bothered to read the thread, use the thread search function, or even read just the first page, because they are too lazy, so they just post questions which have been asked literally 100s of times already, helping to make the thread 1000 + pages !!

Same thing happened to me on my KLD last week. Same ROM and same symptoms. When I re-flashed, it took alot longer than normal and initially I couldn't install apps from the SD card (would just sit on the install screen indefinitely). It eventually cleared up and is working fine now. Don't think it was a heating issue. I do remember that all my Google processes started crashing so I hard reset it. I'm wondering if it was a problem with the internal flash storage. Fingers crossed it doesn't happen again.

Exactly which version of coudu's ROM was it ? Just so we know.
[MTCB Android Head Units Q&A] lmattiso:
I was using Coudu's 4.4.4 v4.2 (plus KLD 2.40 image). Was stable since January and it really seemed like a hardware/flash issue. Mostly because it took so long to re-image the unit. It's been working fine for about two weeks now. I also have Xposed framework and the XposedMTC module running.
[MTCB Android Head Units Q&A] clearchris:
Me too, it was working great since I installed it a few months ago. I dont think heat was an issue, though come to think of it, google play updated a bunch of apps right before the last time it was on before it died, so maybe it was heat related.

Just wanted to give an update on this. I tried one a PAL to NTSC converter and it did not work.
