Actually, I didn't say they (carjoying) were the manufacturer; however I did put JY in brackets because they deal exclusively with JY stuff (or at least they do now).

I did ask specifically about RK3066 and the rep was pretty enthused about it becoming available so we'll see. :)

Buying

Where i get an SoM RK3188 card?
[MTCB Android Head Units Q&A] typos1:
Read the first page, it lists a link to the fileserver.

You dont need to do them separately, its fine to do them together, if the HU fails to auto detect them, try another SD card, especially if youre using the card that came with your HU. Holding power down for 10 secs+ gets into recovery.

If you d read the first page you would have seen the link to the fileserver, if youd gone to the fileserver you would have seen al the firmware (apart from Malaysk's) laid out with all the dates, youd have also seen that coudu's ROMs are far from up to date. It seems youve read the thread up to about March when coudu was adding his ROMs and not since, why else would you think his was the most up to date ROM (although his latest ROM is his most up to date one, but not the most update out of all of them). Malaysk puts links to his ROMs on his signature.

There was a mention of it months back, someone did create one, use thread search to find it, cant see the point though when we have and XDA community.

You can buy KLDs, JYs, and KGLs from Alibaba, its quite easy.

Please refrain from using Eonon model names as they are useless, Eonon sell KLDs or KGLs, just the make (KGL, KLD etc) and screen res (1024x600, 800x480) and processor (dual/RK3066 or quad/Rk3188), reseller models names are useless for help on here). The two versions you mention are EXACTLY the same in all ways apart from the SoM, one is RK3066 and one is RK3188.

Hot Audio make the GS units (or at least that was the conclusion we came to about a year ago, "GS" doesnt make much sense as an abbreviation for them though, "HA" does), they are indeed one of the types this thread is about, you CAN flash any ROM for RK3188 and 1024x600 resolution from this thread. JY ROMs use the launcher in your link, though you can use ANY ROM and change the launcher quite easily.

That unit is a Klyde single DIN model, its the same as the ones in this thread, its best to buy it direct from Klyde on aliexpress, quite easy to find: http://ru.aliexpress.com/store/301644

Malaysk's ROMs are based on KGLs I think, as thats what he has.

Malaysk 4.4.4. problem

Good evening everyone,

the first thing I wanted to thank all the contributors to the forum because I'm learning so many new things and thanks to people like Malaysk I'm updating my radio.

We come to the point:

I have a radio Witson W2-A7047 RK3066-based KLD and (should have) a resolution of 800 * 480.

Initially he had MCU 2.20 and firmware Android 4.2.2 Jelly Bean.

This morning I upgraded to MCU 2.64 and also the firmware android 4.4.4 Malaysk of 26 July 2015.

While some respects I noticed improvements and new features, unfortunately I encountered problems:

1) I can not operate the 3G USB Dongle. With the previous version I did not have any problems. I tried to install PPP Widgets, but not working. Someone told me then to try PPP Widget 2 which is much better, but when I go to Google Play Store to install it, it tells me to check that I have free space on external storage. I have the SD card for the navigation and in addition I have a USB to 64 Gb. Why can not I install this application? And because 3G dongle doesnt work anymore?

2) I can not install new applications

3) I have now discovered that this version of Malaysk does not work with Tomtom. Can you confirm this?

I hope someone will help me to find solutions because I like this MOD.

Alternatively, please suggest me a MOD that does not create problems and I run the USB 3G dongle.

Thank you in advance

WiFi not connecting on KDL RK3066

Hi everyone. I have a KDL RK3066 unit (Jeep Wrangler) from Cool Pumpkin. It worked fine for a while. Then the WiFI would intermittently refuse to connect. Turning the unit off and back on would rectify it. Now it has gotten to the point where it rarely ever connects at all. The WiFi is on. It sees the access points. It shows the connection is saved. But it just won't connect. I've tried multiple access points with and without security. It just sits there dumb as rocks not connecting. If you tap the network and manually select connect, it doesn't do anything either.

Today I tried upgrading to the latest MCU and Malaysk's ROM. It is AMAZING. I love it. But it didn't fix the WiFi either. The symptoms remain unchanged. What can I do to fix this? The whole reason I bought this was for apps the use live data (music, nav, etc).

Also, the AM/FM radio doesn't seem to work now either. I set it for America 1 in the factory settings. Still no dice.

[MTCB Android Head Units Q&A] CARRisma:
A full screen notification appears saying that the app is requesting Superuser access. From memory, I have 3 options - deny, allow once or always allow. As no extra software was installed, I assume it's a standard feature of Android or a feature of our HU installations of Android?

The same prompt appeared when deleting the Adobe Reader apk using Root Browser and also when running that Root Checker app.

Hi everyone, i have purchase an head unit Eonon Ga 5155 specific for Opel Meriva 2006. The unit is Klyde with mcu kld 2.20 and rom 4.2.2 stock. I have two problems: the steering wheel control don't work and the power supply is never interrupted while the original radio is off when I extract the key . It ' possible that the Can Bus module supplied is not compatible with my car ? I have tried to install mcu kld 2.55 and rom 4.4.4 but the problems remain. Thank's

No. Too much effort.

The latest Klyde was working 80% of the time.
[MTCB Android Head Units Q&A] typos1:
Go into factory settings and check its set to the correct radio IC type (if you dont know which IC you have, try all settings), also check that the radio is set to Europe. Also you may need to add a power injector if your OEM antenna has one (check at the base to see if it has + and - wires). If none of this works you will need to open your unit and see if there is anything disconnected from the radio IC inside, there have been instances of wires coming detached in the past. If there is nothing visibly wrong, then return it, again, occasionally we hear of a unit with a dead radio IC.

Impossible I m afraid - the CD/DVD drive is controlled by the MCU, not by Android, plus there is no CD/DVD support in Android.

Ok, will do.

[MTCB Android Head Units Q&A] slackmartian:
I could be wrong here but it seems that more and more people report issues with the radio, and my radio was working just fine before flashing MCU and ROM...

I don't belive it's possible that hardware fails (antenna/IC) for several people at the same time after flashing ...

I have an auto pumpkin (KLD) quad core unit and currently no fm radio.

ROM: update_4_4_4_800X480_4_RK3188_MAL_06_07_2015

MCU: MTCB-KLD2-V2.67

I've tried all chips just in case, any other ideas than antenna coming lose, or IC chip borked... ?

my kgl dead?

Hi guys

Today my radio after reboot does not boot even after an hour. What i did is a change stant by time to 10 minutes and at factory settings a tick rds and change button options to option2 to see if it changes the hardware buttons. When radio ask for restart i click yes and thats it, its dead now. I check power voltage from car and they are ok, also radio fuse its ok.

Hope its not power supply or something... Any ideas?

I upload some board photos.
[MTCB Android Head Units Q&A] mike.s:
Try a KLD MCU instead of the KLD2 one you're using? What MCU version were you using when the radio worked?
[MTCB Android Head Units Q&A] Malaysk:
Install KLD2 v.2.55 factory https://yadi.sk/d/-f454XquhhEbU and then expose your type of radio in the factory settings. The problems will not be.

Thanks I will try that!

And thanks for bringing us these roms, awesome stuff !!!

MCU: MTCB-KLD2-V2.51

ROM: rk3188-eng4.4.4 16042015
[MTCB Android Head Units Q&A] shadowfoxmi:
Yeah, I am sure. I measured the voltage like 30 mins after the ignition was turned off and I got 12.5v on the pin where the HU expects it. I sent back my unit to the seller and they sent me back a replacement. The replacement had a lot of improvements, like better CANBUS integration (shows door open overlays, supports turning on heated seats, gets ambient temperature from car etc). I was able to save radio presets but still no dice with the clock getting reset; it's very frustrating.

Previously the car had it's own right time and the HU alway reset to 7:00am 1/1/2000 or something like that but at least I knew the car's time on dash was right. Now with the improved canbus support it syncs bad time with the car's clock resetting the good time. :mad::crying:

Thank you for your reply. I can resolve the problem of the power off with the 12v accessory wire or installing a button on/off, but my big problem are the steering wheel control that don't work. It possible that the can bus module is not compatible with my car (Opel Meriva 2006) ?
[MTCB Android Head Units Q&A] shadowfoxmi:
Do you have the right CANBUS type set in factory settings ?

It is possible that you have a faulty canbus decoder or the wrong decoder. The label on the canbus box should say which car it is for, I think . Mine says it's for BMW e90. Make sure yours match. I had one where only half of the SWC keys worked. I sent my unit back for replacement for a different reason and I got a new canbus decoder and now all of the keys work.
[MTCB Android Head Units Q&A] Robx77:
In the factory settings i have the correct type set (09 mazda&opel simply) and i have tried to change with all type set but i don't have resolve. I can't post image but the label can bus module is "Opel can bus decode - xfy-20150124 v1.0- kld". The others can bus service work correctly for example light and the option settings from app oem...

[MTCB Android Head Units Q&A] agentdr8:
If a Superuser item appears in the Settings menu, then it would seem they pre-install Superuser, and just hide it (and root access). Makes it even easier then :)

When I had tested that password, I hadn't checked the Settings to see if anything was different.

With any luck, they won't care that we've found and are using their hidden root-enabling password, and remove it from future versions. Otherwise it's back to flashing pre-rooted roms.

I bought a 3.5 mm stereo extension cable but it is not shielded.

Thanks.
[MTCB Android Head Units Q&A] halloj:
I took an old mic-cable that I had laying around. Note this is audio so the shield should not be connected

to the BT-board. The connector is grounded in the chassi. Solder the shield to the chassi-connector, but leave it open

in the other end. Solder the lead-cable to both the BT-board and to the other pin on the chassiconnector. Tip=lead=audio

I've this set-up in three installations and they work excellent. Thanks to Russia.

Upate to 4.4.4

hi guys, this is my first post.

I have a eonon ga5151 (KLD-RK3066) with mcu v2.40 and 4.2.2 with 800x480 resolution and I want to update the firmware to 4.4.4, the question is whether I can install the firmware with 1024x600 resolution?

Another question is whether once updated to 4.4.4, it is possible to downgrade to 4.2.2?.

Sorry for my english and the google translator....

Thanks.
[MTCB Android Head Units Q&A] shadowfoxmi:
Check out the first page of this thread. It has links to file repositories with firmware updates. Also read through the information/instructions in the first page, it's good to know the basics.

Note that 1024x600 resolution updates will not be compatible if your unit came with 800x600; I don't think. So you might want to look for 4.4.4 version with 800x600 resolution. Also for MCU, look for the latest version KLD versions as others (KGL/JY/etc...) will not be compatible.

About the second question, it's possible to downgrade from 4.4.4 to 4.2.2?
[MTCB Android Head Units Q&A] shadowfoxmi:
The file repository also has 4.2.2 firmwares if you want to downgrade. The procedure is same for downgrade as upgrade. I don't know if it would match exactly the stock 4.2.2 you got but it should be pretty close. You can try asking the seller to send you stock firmware if that's what you want.

Thanks for the replay.

Is the mic cable is stereo or mono cable (or it doesn't matter).

Does anyone have this problem ?

[IMG="System Control Settings"]https://cdn.pbrd.co/images/2iTywNSx.png[/IMG]

The temperature indicated in the top status bar says 68.0C. The 68 part is right and is getting it from canbus and matches what's shown on the dash of my vehicle but on the dash, it shows 68F. The screen that is open is the System Control Settings. It shows that Temperature Unit is set to Fahrenheit (F). So there is a mismatch. If I set the settings to C. It corrects itself to showing 20C and then if I set it back to F, it gets it right and shows 68F. But after this, if I reboot the head unit, it goes back to showing 68 C.

I am wondering if anyone else has seen this issue. I have this problem on a unit with KLD2-2.68 mcu and a 4.4.4 rom. I am hoping the MCU sends the temperature part and one of the android apks tacks on the units of measure and displays is and I'm assuming it's an android side issue. I have the VTS solution for all the MTC apks but I'm not sure which APK would be responsible for this display in the status bar. Does anyone know which one I should be looking at?
[MTCB Android Head Units Q&A] agentdr8:
I believe it was added in rather recently, as I had decompiled the Settings.apk from 4.2.2 and 4.4.2 and hadn't noticed those extra passwords then. Maybe it was to ease development for units w/o front usb? We'll probably never know the real reason....

As long as it continues to exist in future updates, I think everyone will be glad.

I would open the dashboard, and physically remove the power to make sure the head unit is totally powered off, then try again.

All might not be lost. There is a way to reset the nand on the rk3066 chips to do a mask rom reset. I couldnt do it with the Huifei units as the module plugs into a slot that stops you getting access to these pins easily but on yours you might be able to do it.

Its kind of a last resort but it has worked for me on a rk3188 tv unit when I bricked it - so I know it does work.

Basically as per the instructions you need to short the nand pins 8 and 9 while turning the unit on - with the usb pluggedinto a pc. The PC will detect and install (or prompt to install) the maskrom device - which will talk to the rockchip bootloader software.

If you want to try this the details are here http://www.techknow.me/forum/index.php?topic=5354.0
