If you don't have something constructive to say to another member; why post insulting remarks? Do you feel better? Not everyone has electrical knowledge nor android nor apk knowledge.....not all of us are 'devs'. Most on here are asking questions to better use our android radio head units and really need the help from more knowledgeable members. Thank you for being helpful to others.....at one time or another you might need help......and if I can answer with help, I will...... regardless of who you are! .........

I have try to keep power , but unit stop and restart until i release power . No beep

MCU is correct , i have kgl4 and i have flashed kgl4 mcu from darkleo

On original rom and mcu , i can enter in recovery with keep RESET+POWER for 5 sec., release reset and keep power , wait for screen on (first boot screen ), release power

I don't know why not work now
[MTCB Android Head Units Q&A] mike.s:
They're automotive units. If your car battery is at 9 V, you have much more serious issues than whether your entertainment system works. If you're running it on a bench and you can't figure out how to provide it with the correct voltage, you're in over your head.

iGo is now failing to start on JY with Malaysk Sep and Oct ROM's - 1024x600 RK3188

I've been using iGO for Navigation since I got my JY units without any problems. While on a road-trip the iGo program stopped working (on Oct 17th or 18th) and it displays the splash startup screen, then stops with no error messages and switches back to the previous active application. This was with the September Malaysk ROM.

I just got home and tried iGo on my other car which has the October 18th Malaysk ROM and iGo does the same thing with the latest ROM. Has anyone else seen a problem with iGO recently?

Hey guys i have MTCB-KLD-V2.40 installed on my HU and i wanted to update to (from sleep) so i updated my MCU version to MTCB-KLD-V2.78, however the radio did not pick up any stations after update so i downgraded back to v.2.40 and radio works again!, is there something else i need to do or need to know?
[MTCB Android Head Units Q&A] pauloxx:
do you damaged pin-put when soldering to R70 and R71?

if Yes no problem. Please turn back motherboard and find 2 short track from Sound processor. Remove paint and solder cable to this track. You don't need new motherboard
[MTCB Android Head Units Q&A] halloj:
It's a long time ago since I used iGo, but if I remember correct this might be because your Save-folder has been corrupted.

Take a copy of the save-folder and after that delete the save-folder. It will bring you to first start and basic installation.
[MTCB Android Head Units Q&A] 3anzai:
hey

got my unit a week ago, 6.95 Quad from Pumpkin ( buttons only, no nobs), as others here before i´m really happy with it and like the build. But hey I used a win CE unit before so its easy to shine against this crappy things :D.

Had weird thing this morning, my Igo was complete back to stock, all settings lost... :confused:, also running Malaysk rom but other than that no problems yet ...

But I`m actually posting about the DVD function

Today I wired rearcam and amp, while opened up half of the car I decided to throw in AV Cables for the rear seat also, the CE thing had Dual zone Function...

How is this on the Android units, I learned that only DVD Playback is possible, thats fine its just for some kiddie movies for my girl. How is the audio working then ? can I listen to music on Front speakers while she is listening on the rear channel . This unit only has rear and front outputs ( high and low), there is no seperate low Audio out for the DVD as on my freaky winCE unit. Anyone using a similar setup ?

I believe there is no app to route the audio signals to different channels , or I´m wrong ?

When I put in the DVD while driving I hear sound but can only see the command buttons (brake line not connected yet) but when I switch to another app the dvd stops....
[MTCB Android Head Units Q&A] :
Hi, is anybody aware about following:

I install Tomtom Go, and with it, it is all fine. Unfortunately Tomtom needs to be online to show traffic cams (even the fixed ones)... so i installed Pumpkin 3G stick. When i plug it into usb and it connects very well and start then tomtom, it crashes immediately. I need to reinstall tomtom. Without stick i can use it without any problems. I bought another 3G Dongle with 1750 Chip. Well it needs manualy to set APN Setting but it works very well too. I start Tomtom and it crashes again. The first stick had option to include sd card, so i tought thats about this option so the 2nd stick is without sd card feature.

Maybe i can hide the stick for tomtom oder something else? It crashes even when iam connected via wifi so that the 3g modul is in idle mode. Maybe someone can help.

I am with tomtom in contact but you know... rooted device... bla bla

[MTCB Android Head Units Q&A] dazza007:
I need a new motherboard the solder is just not bonding. Back to same problem with poor sound and have to pay yet more money to have poor sound... absolutely gutted as I had everything soldered and I the software had reported error and the problem due to 7floors post was soldering. Unfortunately it wasn't as the post on pda.ru had the wires the wrong way around. So I unsoldered and resoldered the connections which caused the pin-put to be damaged.
[MTCB Android Head Units Q&A] Tutti-frutti:
I just opened up my KGL head unit to see if it's easy to do the microphone mod.

In my case, it's a HU

with an external microphone connector onboard

. In the posts I read about removing C102 (or C32) to disconnect the internal mic from the BT unit, I only read about connecting an external microphone directly to the BT unit. I assume this isn't required for my HU, as I have a external mic connector already on board. Is this true?

Is it enough to remove c102 or will this also disconnect the external mic input?
[MTCB Android Head Units Q&A] grahamwright1:
That solved it - thanks!
[MTCB Android Head Units Q&A] Tutti-frutti:
Thanks for your clear explaination :good: I will search for/buy a mic connector.. or even better, just connect the wires directly to the original car mic which I assume to be much better than the bundled chinese external mic ;)
[MTCB Android Head Units Q&A] Twilek:
Just as a quick info: I had, as many others had, problems when upgrading ROMs from within the ROM with the data always being completely wiped during the upgrade . I now upgraded a Malaysk ROM to the latest Malaysk ROM via the Recovery Image with the Upgrade option without the "wipe all" and it worked flawlessly.
[MTCB Android Head Units Q&A] gita123:
Already try that way, almost 1 minute I press power button, but nothing happen. Sometimes I can boot up with reset but It can not shutdown with power button then shutdown with acc off but then can not boot again. And when I look about machine menu, It shows MCU name was partly deleted. Is It MCU problem?
[MTCB Android Head Units Q&A] koimr:
You should re-read the posts in question; no one was claiming that our units should function on 9 volts and [MENTION=6869759]DWilks[/MENTION] even said it was the cause of his problem (he didn't do it deliberately).

He passed this information onto the forum and I thought it was a useful tidbit. I really don't know where you are trying to go with your response above, it's already been decided the 9 volts was a mistake.
[MTCB Android Head Units Q&A] Profane4711:

Missing: 'Services' under Android Accessibility settings?

Recently I installed an app that required me to enable a service in the "Android Accessibility settings". I then realized that on my JYHU the entire SERVICES (I am capitalizing SERVICES because it is capitalized in Android) menu is missing under Settings->Accessibility, only SYSTEM is there. Typically under Settings->Accessibility there is SERVICES such as Talkback, etc.

Can anyone check under Settings->Accessibility and tell me what sub-sections there are (i.e. SERVICES, SYSTEM)?

I am wondering if we have a crippled Android ROM where apps cannot add SERVICES, they are [intentionally] hidden somehow or if there is an app that is hiding them.

This is really hurting me as I cannot make certain apps behave properly without the accessibility settings.

I read in another thread that manufacturers (allegedly) do this sometimes on purpose (I think it was the Nook tablet).

http://xdaforums.com/showthread.php?t=1400615

I am going to post this in more than one thread because it is Android related but I am dealing with it only my JYHU (my Nexus 7 does not have this issue).

[MTCB Android Head Units Q&A] dazza007:
You need to change the canbus settings and the radio tuner settings to the correct type.

If you didn't record radio and canbus type before you flashed the unit best thing to do is trial and error.

Go into the factory settings menu with password 126 and it is on the first tab on the left

Hello everyone,

I just installed Malaysk ROM (great job) on my KLD2. I have a question is it possible to enter 5digit pin code for a bluetooth device ? I have a bluetooth that is connected to my engine computer - similar to OBD2 and it has 5digit code. From the bluetooth app it`s only possible to enter 4 digits :crying:. I installed xposed also but that didn`t do the trick. I was wondering if it`s possible to override it or pair it manually somehow or maybe there is an app to do it ?

Second question - when I go to factory settings change something and then save it hangs on power off and I`ll have to reset it manually. I don`t know if I mess something in the installation process ? Is there a way to wipe everything to 0 a install the fresh ROM again ?

Thanks

Hi All,

I'm considering purchasing one of the CarJoying Units and would be grateful if anyone could answer a few questions:

1. Has anyone succeeded in running a multi window setup through this or another Xposed plugin?

http://xdaforums.com/xpos...vable-t2419287

http://repo.xposed.info/module/com.z...floatingwindow

It would be great to run waze or gmaps at the same time and on the same screen as the music player, torque, or another app.

2. Is it possible to hide/minimise the statusbar on the Malaysk rom?

3. Does PetroWS MTC Service work on RK3188 devices or is their an alternative that provides the same functionality.

[MTCB Android Head Units Q&A] DWilks:
[MENTION=5135188]koimr[/MENTION] You are exactly right! I only offered the info in case someone else had problems with their sound not working. I'm running off a car battery in-house to test different apks and especially sound apks and gps navigation. This is much easier than sitting in a hot car fighting the heat and bright sun light! The specs on the particular audio amp in my JY head unit list supply voltage as 14.4 volts +or-

10%. So 12.96 volts would be the minimum voltage according to specs. Since I'm not connected to a vehicle charging system, my battery voltage has gradually lowered past the operating level of 1 or more components inside my head unit.

That's to be expected.

NOW! for a new problem that someone else has mentioned: The Volume Control,

my unit has the physical pwr/vol knob, stopped working and also the volume window that should pop up no longer did. To get the volume control back working, I had to reboot the unit and all was back to normal. A voltage check at the time showed 12.3 volts from the battery. My volume still worked, but I could not change it either up or down. Neither problem was fixed by powering off or applying the correct voltage. That took a reboot with the correct supply voltage.

This post and the one about the sound not working is just information posted for others to see that the battery state is crucial to the correct operation of these radio/navigation units! So, if your unit starts acting strange, it might behoove one to suspect a voltage supply problem and not apks nor mcu's nor roms! That's 2 problems that someone else has mentioned duplicated on my unit with battery voltage below levels that the unit needs. Hope this helps others....your problems may vary but do suspect battery supply voltage especially if your vehicle is not actually running when the weird problems occur or if you've just started your vehicle like in the morning or a long time in between running........

I have been working on a lockscreen setup solution for our Android HUs; I have it working decently on my Nexus 7. However when I tried it on my JYHU it would not work due to missing 'Services' under Android Accessibility settings.

[MENTION=6953386]JEMShoe[/MENTION] JY unit 1024X600 Malaysk rom........here's my screen shot but I don't see any "Services". Perhaps an apk adds this to the Accessibility tab and I just don't have an apk that adds it....just guessing on that.

[MTCB Android Head Units Q&A] JEMShoe:
I installed an app on my JYHU that uses Settings->Accessibility:SERVICES on my Nexus 7. Services still did not show up on the JYHU.

I believe it is because our Settings.apk is missing the Settings->Accessibility:SERVICES.

If anyone is using the stock ROM please look under Settings->Accessibility and tell me what sub-sections there are (i.e. SERVICES, SYSTEM) and reply (and maybe post a screenshot of your accessibility menu).

Meanwhile I will write Joying and ask them if this function was removed; if so, ask them to put it back.

Accessibility is what it sounds like--it can be used by people with limited mobility. In truth, when driving in a car we all have limited mobility in that some activities jeopardize safety.

See this helpful post from Google for more information about Android accessibility features.

Of particular interest is the Service called "Switch access".

BTW, do not try to install TalkBack on your units. First of all, it will stop working.

Second, it tends to block touch screen inputs. Luckily I had a USB keyboard connected while I was testing this and was able to navigate the screen using keys and disable TalkBack then uninstall it.

But I installed it because on my Nexus 7 (even though it is disabled) it uses Settings->Accessibility:SERVICES. But it never showed up on the JYHU.

---

I don't have experience in modifying APK files but I am curious if there is something that can be added to 'enable' the Settings->Accessibility:SERVICES category in our HUs.

Here is what the \Settings\res\xml\accessibility_settings.xml file from my Nexus looks like (I don't have time right now to look at the JYHU xml):

<?xml version="1.0" encoding="utf-8"?>

hello everyone

i am looking to find a way to have TTS voice guidance to work over radio all audio.

There is a app, that allow to stop/lower volume of other streams when the TTS engine makes an announcement. I think this works only with apps using STREAM_MUSIC as the streaming channel.

I Tried it with spotify and the mtcradio app.

with spotify it works, eg the audio stream gets quite/lower so that the TTS announcement ist clearly audible, and continues after the announcement, with the mtcradio app it doesn't work, neither while listening to mp3 on a dvd. ( the announcement is made on top of the audio stream, so that its not clear).

does anyone now which Stream is used from the mtc apps ? is it possible to redirect this stream to STREAM_MUSIC or modify those apps to use this without problems?
