[MTCB Android Head Units Q&A] 2safe4you:
I found some strange thing's that i not understand.

First my Hardware:

BOARD: RK3188 (quad core)

DISPLAY: 1024x600

MCU: JY V2.59

And my Software that i try:

Joying RK3188 Quad-Core - 1024*600 Update from 03.09.2015

Malaysk RK3188 Quad-Core - 1024*600 Update from 03.09.2015

First installation was the original Update last Week from Joying: MCU and FIRMWARE.

First time that i updated my Headunit.

Everything looks good, all are working normaly: play a mp3 from usb, play a DVD and i can hear Radio.

OK, now. Update "THE NEXT LEVEL".

I will try to update to the Malaysk Firmware MOD

First look was good. Everything looks and work normaly.

After a while i found some strange thing's.

I play a MP3 File from USB in the MEDIA APP.

It shows only MP3 Filename. NO SONGNAME, NO INTERPRET, no COVER in Mainscreen

OK,... hmmm But I'm sure on the first original Firmware that my Radio comes, i see the MP3 Filename, Song, Interpret and COVER in Main Screen.

Try to Download some App's from Google Store.

A Message... you can not Download, not enough Memory (Sorry, i have no Picture from there).

Hmmm after this Update something looks strange.

OK, back to the original Firmware from Joying.

After some Minutes install and Reboot, i go to the Google Store and try to download and install the same App's from before.

OK, it works. Hmm... Everything works. KODI and NAVIGON is starting.

What happens now with my MP3 Song from the USB.

Press Media, choose the same Song...

... ohhhh the SONGNAME, INTERPRET, MP3 Filename and the Cover in Mainmenue. Ok, it goes and look good.

Now i update the again to the Malaysk Firmware MOD.

Show the MP3... nothing only the MP3 Filename

and i try to start the Apps KODI and NAVIGON... nothing... NO MEMORYCARD !!!

What is this?

Any a Idea???

Here are some Picture to show you.

Greet's

Edelbrock Street Fire

Guys,

Edelbrock make a Fuel Injection setup that uses an Android Tablet for its gauges, etc. Trying to get it to connect up to my GS unit. I have installed a custom firmware and the MTC tools. I see the Computer but when I press connect nothing happens..

Anyone have anything to let these two things connec?

Poweramp losing music library

Hi all,

I am running Malaysk's ROM on an Eonon GA5150F.

I am trying to use some large USB devices. 128GB USB stick and also tried a 120GB SSD + USB adapter for music storage to use with Poweramp.

When I scan the the USB drive Poweramp has no problem reading a playing the files (did a 1 hour drive after scanning)

The issue is when I came back to the car after a it has powered off, Poweramp seems to forget all about the the USB storage until I rescan it.

I guess this is some kind of timing startup issue? I did try ticking "wait for USB" in the startup builder.... But to no avail.

Any ideas on what it might be? Filesystem scanning delay?

Cheers,

Weasel

Hi, *

I got an RK3188 (Erisin ES2698V) device and got, like most of you, awful microphone sound (it is not noisy but really really silent). I bought an original FISCON VW HFP Microphone with 3,5 mono-jack.

After I opened the device, I saw that I have got no C32 to disconnect, also I have not got a BT-Module where no "MIC IN" nor something else is written on. I was not curious enough to try to fix the Mic-issue on my own :). I know, I am a noob in electric but have someone got a newer device like me, too and can help in this case?

Maybe you have a solution to increase the gain of my microphone without increasing the noise by software?

really strange is also, that the Quality check of my device was in October 2013 but the manufacturing Date in June 2014 :confused: . I don't think this is right :D

Regards

Chris
[MTCB Android Head Units Q&A] ChrisKay1988:
okay thanks a lot. The pictures in th ewiki differs a lot from mine so I need to search for the connection between internal mic and the BT-module.

One question besides: is it OK to use a multimeter with 9V? I can imagine, that this is way too much voltage for the connections, isn't it?

regards

Chris

PS:

Thanks for the tip, this is what I wanted to do here. I read a lot in thes thread and th emore I got surprised that my PCB layout differs so much from yours (Its a KGL). Need more research for this.

Hello,

I've got a RK3066 head unit (Klyde one) with android 4.4.4, and im wondering if i can connect any bluetooth keyboard to it (it detects the devices but when clicking to pair, nothing happens). Anyone knows whats to be done ?

Thank you !
[MTCB Android Head Units Q&A] agentdr8:
I don't believe there is BT HID support, so your best option would be a usb keyboard, or possibly a wireless one that uses those tiny 2.4Ghz dongles.
[MTCB Android Head Units Q&A] fabianosan:
Here works fine with the last version, is Klyde Unit with 2.64 MCU and JY last firmware.

I defined "180" DPI in App Settings (Xposed module) and in Google Search, I'm set the option "Ok Google" in all screens and works fine.

The best way to app recognize the voice is turn the sound mute and saying "OK Google", I can do it by a steering wheel button on my car.

[MTCB Android Head Units Q&A] agentdr8:
Unless you've got a bench power supply or a spare car battery, the easiest way is to grab an old PC power supply. The ATX connector can be jumpered to power on without needing a motherboard attached, and provides 12VDC. See here for more info. Yellow wires are +12V, red are +5V, and blacks are ground.

Twist together the ACC and BATT wires from the headunit harness (red and yellow) and attach them to the yellow wires on the power supply. Connect black ground wire on harness to black ground on power supply.
[MTCB Android Head Units Q&A] hobbes_VT:
Thanks for confirming that this isn't a general issue but rather observed by some individuals.

I'll try to flash another ROM and see if it persists.

Now that I know it must be my specific configuration, I also have another suspicion - it could be one of the settings in the HeadUnit app or similar e.g. the setting to make calls through BT. I'll do some testing and report back in case I find the culprit.

My phone is a HTC One M9 - which may be another difference - some phones send a "wake-up" to the Bluetooth units when they connect, which could trigger the phone app to launch.
[MTCB Android Head Units Q&A] vdubskey:
If your not comfortable opening up a pc psu and re wiring it, just search eBay for led power supply. I bought my 12v 30a unit for 30 bucks shipped last year for my 3d printer and have been using that for my double din bench testing as of late. You can adjust the voltage from 9v to 14v and its stable.
[MTCB Android Head Units Q&A] gurumaia:
Thanks, I'll take a look into it. Have to see if I've got an old PSU lying around.
[MTCB Android Head Units Q&A] rhacy:
If you don't have an old 12vdc PS available, you can also use a small adjustable amperage 12vdc battery charger. I run mine at 2 amps when setting up head units without any speakers attached. If you're going to attach speakers, you can set the charger amperage higher, but just make sure to stay below the head unit fuse blade rating. Moreover, when running higher input amperage for speakers etc., I recommend adding an appropriate size inline fuse between the combined HU red ACC & yellow BATT+ wires and the positive charger clamp in order to protect the head unit further.

Best to all,

R

DAB+ receivering

I tried on 5pcs mobile phone, but I don't buy this app. At last yesterday I wrote the issue to the developer.

Yesterday I tested my solution.

When I was 5km far from the DAB tower (ERP only 0,25kW) and I could see the tower the reception was perfect (Full signal: see the 9pcs green squares):

[IMG="Reception wrong"]http://kepfeltoltes.hu/150916/Screenshot_2015-09-15-17-49-48_www.kepfeltoltes.hu_.png[/IMG]

But I was 6km far from the DAB tower (ERP only 0,25kW) and I couldn't see the tower the reception was "0", I hadn't signal sign:

[IMG="Reception is OK."]http://kepfeltoltes.hu/150916/Screenshot_2015-09-15-18-59-03_www.kepfeltoltes.hu_.png[/IMG]

My conclusion is:

- The built-in window horizontal stock aerial doesn't suitable for DAB receiving, because the DAB+ broadcasting is vertical (in Hungary and some EU country) polarization.

- I have to buy/try another DAB+ aerial.

Does anybody use DAB aerial in own car?

Hi all,

I am running Malaysk's ROM on an RK3188 Joying 4-core.

i face an issue. I installed Waze and Poweramp which use some settings and scan library data which are saved i don't know where (maybe SD card) and regurlaly when i turn the unit on, theses apps lost their data. In waze, i have to authentificate again and poweramp starts a fresh music files scan.

I don't know what happens. It occurs 1 out of 3 times i turn the unit on.

Any idea of this problem?

Thanks
[MTCB Android Head Units Q&A] clearchris:
Ok, I have been having some strangeness the past two weeks. The incidents may be isolated or may be related, I'm not sure. I'm running a KLD 800x600 dual core. I'm running a january version of the ROM with the russian sound tweaks and new sleep timer.

First, I'm driving along, and I hit a pothole. Nothing really bad, but it was slightly jarring. The radio keeps playing my music, but I see the android boot up screen (not the kitkat screen, the one after). After 2 minutes, the bootup does not complete, but strangely, the music keeps playing, getting the next song, etc. I hit the reset button, the unit boots, and returns to normal.

A week later (edit: has been working fine for that week), I turn on the car, and all my settings are gone. I was running nova launcher, but the stock launcher comes up. I bring up pandora, but pandora does dies during startup. All my other programs lost their settings too.

Seems like maybe the internal flash card is going bad, or maybe bad power (caps dying?).

Anyone have any guesses or ideas to look into?

Has anyone successfully tethered their phone's internet via Bluetooth to these units?

Newbie to the Joying HU here, with the help of 'doctorman', I got a Highlander version of Joying 1024 RK3188 unit yesterday. Other than taking out the dashboard, rest was straightforward to install. My unit works well and the highlander steering wheel controls work well with the unit. Updated to Malaysk's ROM. Few questions:

1. I have a 'mode' steering wheel button that alternates between DVD-Video-APin-Navi-Radio-etc. Is there a way to program this button so that it just alternates between Poweramp-Navi?

2. Is it possible to customize the other buttons for short, long and double presses. Eg. I would love to switch to previous application using 'Phone down short press' and 'Speak' button to launch google now?

I have the default app (reads some like HEAD...) from Malaysk ROM that enables to set a default audio application, enable steering wheel controls to work with this audio application, etc. It has been only a day since I got the unit, apologize if my memory lags on the application names.
[MTCB Android Head Units Q&A] fabianosan:
Strange beharvior, maybe is your ROM version, do you did test with another firmware?

I use Waze and PowerAmp here with a Klyde RK3066 and don't facing this issue. I installed inside flash storage and moved apps data to GPS SD card, and MP3 files are in USB storage.

I use the last JY Android firmware.
[MTCB Android Head Units Q&A] agentdr8:
XposedMTC. For just these two sources, it should work fine.

For hard-button remapping, you can use mtc-keys. There's no support for long or double press though.

[MTCB Android Head Units Q&A] flydeep:
Thanks, will look around for some examples to set it up. I could swear I read a post where someone set it up with long and double presses and I wanted to do that when I got my unit.

Another Q about upgrading the MCU and the ROM. On my unit, I need to press the power knob button for ~ 10 secs before it will go into firmware mode. Although I had both the MCU.img and update.img in the root of my sd card plugged into GPS card slot, only Malaysk ROM got updated (had to two do this twice). My MCU still shows as Aug 23rd, 2015 while the newer MCU is from Sep 3. I am under the impression that both the MCU and ROM update will happen simultaneously.

[MTCB Android Head Units Q&A] Tumke32:
Thanks for trying. I understand that your buy and download problem is solved? Should it be an option to put a 2 way splitter on the usb dongle and connect them to 2 different aerials. One way to the existing aerial in your car mounted horizontally in / on your window for the FM signal. the second way to a dab+ aerial mounted vertically on your front window for the dab+ signal.

I understand that your fm signal is good with the existing aerial, i don't think your fm signal will be just as good with only a dab+ aerial. So maybe this 2 way idea is an option. But i don't know if its technically possible to let Wavesink work with two different aerials.

Can you post some pictures of your aerial connections? I need to find a male coax converter to i think a female sma connection. Otherwise it's not possible to mount a dab+ car aerial on my usb dongle. Were did you buy the converters?

In the recovery you can chose to upgrade the MCU or the ROM

also just because there is a new ROM from JY on sep 3rd does not mean both the ROM and MCU is updated on sep 3rd.

probably just one gets update at the time but they are both included in the Zip file.
[MTCB Android Head Units Q&A] typos1:
OK, well pretty much all of that applies to the HuiFei and probably the RM and Klyde units aswell - kwalsh24 snd others have had problems with the CAN Bus interface, although all units are supposed to support dual channel CAN Bus, the fact that your previous 2.3 unit did work is encouraging as it proves it can be made to work. Maybe you could try to use the app and decoder on you new unit ?
