Many thanks , i also use SVOX and volume is increased at 200% (after sound is distorted) but it is still too low
[MTCB Android Head Units Q&A] MasterPrenium:
I quickly test it. It's android 4.4.4 from KGL. Everything works well except I got an error on android Play Store (I didn't have time to check more, maybe it's related to the 1024x600 screen). And it also has a real Tablet display mode (settings in two columns ect ...).

in the factory setting I have radio on 8 and system-volume-12
[MTCB Android Head Units Q&A] SteelH:
GA5153 (KLD) head unit installed. KK 4.4.4 installed, firmware 2.16. Most things seem to be working so far. Awaiting adapter for VW diversity antenna (currently radio reception isnt great, some stations come in, many do not). Tried to make a call via BT, I could hear caller fine, they couldn't hear me at all. (I'm aware there have been reported mic issues, will spend more time on that later). steering controls work, canbus stuff all seems to work. Paid app/play store no issues. Wifi works. Hard buttons no issues at all, back button goes back, not GPS. BT ODB + torque pro no issues.
[MTCB Android Head Units Q&A] Petrows:
Thank you for the test and feedback, it is very important fo the me and my app!

Yes, it is not a problem to start from script, but this is firmware maitener area - app in Goolge Play has some strict limitations and can not modify some scripts on normal way. But there are some other ways:

app can catch also irKeyUp event from microntek for start service (has some problems, not 100% starts);

app can catch also some other intent what is raised from the script;

app may hold some butoon for system install like "make startup quicker (requires root)" to install app in script;

So, why you need quicker start?

This is a complex problem. Of course it is possible to run specified app, but "just run" is not enouth - on boot other microntek apps could start in parralel (for example radio) and became play together. My app has feature that sends MEDIA_STOP button on some other Microntek app starts to stop any custom player, on base of this algorythm i think it is possible to wait a little on boot for any micronteck app - and if there is no activity - start the player. Good idea :cyclops:

Extra step might be easier - google sync works good in True Contacts - i just enabled "sync contacts" in account settings.

Reply and complex replace of stock bt app is quite possible for now, there is no super-difficult to control the bluetooth in headunit. But for now process of total replacement is only in the begiggning. Now im working on widget for recent calls with normal contacts - mixing bluetooth contacts and android phonebook. And there are a plenty of work ahead :cool:

Thank you for the report - i think im on the right way.

P.S. my app is open source and you can make push request of your own ideas at github: https://github.com/petrows/mtc-service

Petrows, your app is like carservice? I tried it whishing to change one swc button funtion but no has this feature. Do you know any way to do it? I need desable one key on swc
[MTCB Android Head Units Q&A] fedmond31:
Thanks i will try that, i have radio on 0 and system volume 20 it was best i could achieve.
[MTCB Android Head Units Q&A] RyanBRZ:
Do you know what steps I could try to get it to work?

I thought about that, it eventually goes into standby mode if it's sitting inactive for long. I even set the settings to never standby and it still does. Hoping to get usb to work.
[MTCB Android Head Units Q&A] Petrows:
My app is not a copy of car service, but covers some features of it - in SWC. Car service includes more powerfull settings of SWC, but my app has many other features and my app has differences in SWC keys remap algo. Check out description on Goolge Play app page.

What problem do you have? I think allmost all the problems could be solved in app.

[MTCB Android Head Units Q&A] agentdr8:
I would just plug the 3G dongle in before starting the headunit, and then once booted, try the PPP widget to configure it.

Give this a read. Android applications that include services are started after all system processes are started. You can't create a non-system app and have it inject itself into the linux startup process. It has to adhere to the convention of registering a broadcast receiver, and waiting for an intent to do something.
[MTCB Android Head Units Q&A] RyanBRZ:
I tried, but it looks like PPP widget requires usb host capability, I used the usb host checker and I do not have it. Do I need a special cable for that?

If i do need one: My dongle is standard usb size and all usb host cables on eBay have a standard size usb jack with a mini usb female plug so I would not be able to use those.
[MTCB Android Head Units Q&A] SteelH:
Having a ROYAL NIGHTMARE getting tomtom 1.4 installed to extsdcard on my ga5153 unit (KLD). Running coudas 4.4.4. Tried the install-recovery-sh script... didnt fix the problem. Edited the script to say 'exSdCard*' as the gps and sdcard slots on my unit are 'extSdCard' and exSdCard2'

Also tried putting all files on extsdcard and installing apk from there. When I started the app, it wanted to download the maps to /sdcard (internal)

Any thought on this? Tomtom has zero options for where it will download the damn maps. And apparently I've waited to long to get a refund in the play store.
[MTCB Android Head Units Q&A] agentdr8:
Yes, if you ran am commands from install-recovery.sh (or from any init.d script) you could start services and/or foreground app activities, possibly before the intent is received to signal services to normally start on boot. It really depends on how the service is programmed; if you can start it with am and it takes care of any sort of initialization that needs to be done, then it should be fine.

Case in point, take Poweramp's service. It isn't designed to be started directly (with am or otherwise), and relies on receiving intents from the main player activity to know whether to resume playback, where the current track is, what the current album art is, etc. Starting the service without that additional information either won't work, or the service won't do anything useful while sitting in the background.

All of this is really just workarounds to a problem specifically with the 4.4+ roms. Maybe they are unaware that some changes they made have altered how the BOOT_COMPLETED intent is broadcast and/or received.
[MTCB Android Head Units Q&A] agentdr8:
There's no harm in leaving the broadcast receiver in for the BOOT_COMPLETED intent. If the service is already started/running, it won't start again.

Short of changing the apps into ones that require root access, there's no way to insert an am start line into the install-recovery.sh file or drop a script into init.d. Those modifications would have to be made manually, which isn't very user-friendly.

Poweramp doesn't have an option to start on boot.
[MTCB Android Head Units Q&A] SteelH:
My HU is a KLD, GA5153, running KK 4.4.4. It has /sdcard, /exSdCard, /exSdCard2 - internal, ext sdcard #1 and ext sdcard #2 respectively.

I'm going to test editing their metadata.xml to point to exsdcard and moving the map files there and seeing if it will load up.

I also modified the /system/etc/permissions/platform.xml WRITE_EXTERNAL_STORAGE media_rw to allow writing to the external sdcards.

On another note, the BT calling with mic is complete crap on this thing.

[MTCB Android Head Units Q&A] SteelH:
I am indeed using

KLD_4.4.4_800x480_141223_rooted_light_reparted_init.d_v4.2.zip

And that did NOT resolve the issue.
[MTCB Android Head Units Q&A] manicuspanicus:
I have coudu's 4.4.4 v2 installed and I ve been using your software which I liked. Today I thought I would install power amp so I installed car service 2.0.2 and xposed framework with mtc module. What I have noticed is that by switching from radio to av in to power amp etc after a full circle, when it should start from the beginning (radio again let's say) your app crashed. Anyone else seen something like this?

Hello typos1,

did you make any advances in establishing communication between the HU itself and the CAN-bus ?

- In my case, CAN high and low signals from the car go to the CAN-Bus-adapter, from the CAN-BUS-adapter there is white cable going to CAN-RX of the HU (but the CAN-TX of the HU isn't connected at all..).

I would really like to know whether SWC on CAN-BUS cars is supposed to work via the CAN-Bus Adapter translating the SWC-signals into resistances for the key1 / key2 cables, or whether the SWC signals are transferred by other means to the HU, e.g. via this white CAN-RX cable mentioned...

BR,

Michael

Is this mod for all MCU's ? I'm still at KGL v1.77 and Android 4.2.2. Now that I've problems with failing HU amplifier, I took the unit back into my lab and can experiment until the amplifier problem is solved. Every time I start the radio app, it stops at the moment RDS kicks in. The sound of the last selected station keeps playing. Maybe my MCU version is to old? It's a shame, because I like the way you modded it.

[MTCB Android Head Units Q&A] RyanBRZ:
A few questions:

Those using PPP widget with a USB dongle, do you need a special cord for this to work? Does it only work with certain versions of Android? My unit is Klyde, running KLD_4.4.4_800x480_141223_rooted_light_reparted_init.d_v4.2 on MCU 2.12. When I use USB Host checker, it says I do not have USB host. PPP widget says no device found, PPP widget 2 constantly says searching for device. I've tried connecting the dongle before boot and has no effect. My dongle is Sierra Wireless 250U on freedompop (Sprint). The dongle lights up and stuff but PPP widget does not recognize it. Any help with getting my dongle to work is appreciated.

Are there any music apps that are built into the home app like MTCMusic that will show both the folder and music list? My music is organized in album folders and I'd like to select the folder in one column and have the tracks appear in a column next to it.
[MTCB Android Head Units Q&A] MasterPrenium:
USB Host is nothing to do with cable. However maybe you need USB OTG ?

I'm sorry I don't have a 3G dongle to help, but basically you should use at least ifconfig command from linux (maybe you'll need to install busybox) to see if your PPP device is detected/connected/has IP or not.
[MTCB Android Head Units Q&A] RyanBRZ:
I read that it there is a difference in cable. What exactly is OTG?
[MTCB Android Head Units Q&A] ultradj83:
OTG is the chance to attach USB storage, nothing to do with 3G.

About PPP widget, delete the APN in the system configuration and create the profile on PPP widget.

Set PPP widget to check connectivity via Wi-Fi or not, have a try.
[MTCB Android Head Units Q&A] RyanBRZ:
How exactly do I delete the APN, is this just a file? Can I create the profile on PPP if it cannot see my dongle?
[MTCB Android Head Units Q&A] mikochu:
The two USB cables that come with the head unit act as OTG cables...
[MTCB Android Head Units Q&A] ultradj83:
You can delete it if you see a Mobile Data entry in the network settings.

Not all the firmwares allow this.

If PPP can't see your modem maybe the logical port is busy with the built-in 3G subsystem or your unit can't power your modem. What modem are you using? If it provided with a Y cable to get power from 2 ports?
[MTCB Android Head Units Q&A] agentdr8:

GPS locking

Hi,

I have a Klyde universal unit. All has been working quite OK (except for bad radio sound etc), but recently I have had problems with GPS locking. At first GPS worked fine, but all of a sudden it did not manage to lock GPS - the icon on the notification bar even did not start blinking. At some point it was working fine again (started to work all of a sudden without me doing anything), but now it does not find my location again. In GPS monitor it shows one or two low bars, but does not manage to lock location. I have tried different GPS Status apps, but all fail to find satellites or location.

It has been the same with different MCU/Kernel/Android versions.

At the moment I am using the MTCB-KLD-V2.16 MCU, 4.4.4 Android (coudu 4.2), Kernel 3.0.36+.

I have opened the unit up, the GPS antenna seems to be OK. I have tried a different GPS receiver, but no help.

Has anybody had a similar problem and been able to fix it?

Thanks,

Joosep
[MTCB Android Head Units Q&A] RyanBRZ:
The modem powers up as far as I can tell since the lights light up when plugged in and eventually turn to blue which I think means it booted up successfully. It did not come with a y adapter, it has a USB plug built onto it and that is it. I'm running 4.4.4 as I posted a few posts ago.

Hi all.

I have a JY unit that I have just installed coudu's 4.4.4 onto.

With the previous JY software, when I changed sources from radio to DVD or and other app, my automatic radio antenna would retract, and go back up again if/when I selected the radio source again.

Coudu's software doesn't do this - the antenna goes up when I start the headunit, and remains up no matter what source I select.

Is there a way that I can have this feature again?

Thanks,

Tom.

Many thanks!

Hey guys just joined to say this thread is a life saver. Many many thanks. I bought an Eonon GA5153 for a 2015 VW Jetta TDI.

I nearly returned it to Amazon because of issues it has out of the box. I have resolved most at this point. Mainly TomTom

having the "no carrier rockchip rk30sdk" error on the Google Play store. Also MANY apps would not even show in a search.

I am using "KLD_4.4.4_800x480_141223_rooted_light_reparted_init.d_v4.2" with the KLD 2.16 MCU.

All good. I did have to go into the factory menu to reset the VW logo and CANbus (VW-SKODA(Simple)).

TomTom USA purchased legit from the Google Play store now works. The 2.56GB map was a nightmare and took

5 tries to get it to download without failing. I had to get a wifi repeater to get a strong enough signal close enough

to the stereo. Then all went well BUT TomTom sees the 'FLASH' memory as the place it stores the map. I can't get it

to go to the GPS SD Card slot >_< I would love to resolve this.

The MCU's music player is a joke and doesn't see the GPS Voice mix settings. I had to use a free music player (N7)

to be able to hear nav commands AT ALL.

The iPod works but the MCU interface is horrible.

Questions...

1. There is audio AUX L/R IN RCA plugs on the main wire harness. Where does I select AUX in the interface ? I only see the AVIN.

2. The VW Jetta has a mini jack AUX in beside the power socket. How is that hooked up? The EOM stereo used it some how.

3. The VW Jetta also has an MDI port that the EOM was using for iPod/iPhone hook up. Thought on that?

4. Do the 3G/Wifi usb cables do anything?

5. Can I route a phone charger to any of the USB in?

Again MANY thanks to you guys.

2. You can modify it. I haven't modded mine yet, but it's doable.

3. The MDI module isn't usable. I disconnected mine completely.

4. The 3G/Wifi USB cables are your "OTG" cables. They allow you to connect peripherals to your head unit... 3G modem, OBD II adapter, phone, keyboard, mouse, etc. I have one USB port in the glove box and one under my steering wheel.

5. You can charge your phone using one of the USB ports, but you're better off with a 12v USB charger with a high quality fast charge cable...

CAN-Related question:

[MTCB Android Head Units Q&A] typos1:
Re some of your questions :

What makes you think 4.4.4 cannot be rooted ? It can be and there are several pre-rooted images available.

You mention a "save" MCU update, I take it you mean "safe" ? If so there is no "unsafe" MCU update - no one has had any problems flashing an MCU update, the only problems have been either from installing an MCU from a different manufacturer on a unit or loss of functionality/certain errors occurring, but both of these can easily be rectified by flashing another MCU version - in short - YOU CAN FLASH WHATEVER MCU VERSION YOU LIKE, AS LONG AS IT IS FROM THE MANUFACTURER OF YOUR UNIT, SAFE IN THE KNOWLEDGE THAT YOU CAN CHANGE TO ANOTHER VERSION IF YOU DO NOT LIKE HOW THE UPDATED MCU PERFORMS. If you meant backup your current MCU, then there is no way to do that.

The CAN Bus adaptor is used to extract things like reverse signal, illumination signal, speed pulse etc from the CAN Bus system and turn them into analogue signals for the headnunit, the units apparently can interpret CAN Bus data like time, date, trip computer info, door open warnings etc.

Some CAN Bus cars have resistive SWC, some do not, so there is no definite answer to your question, you need to find out what system you car uses, have you tried connecting the key1 and key2 (and ground) wires ? CAN Bus cars that do have CAN Bus SWC will take the SWC signals from the CAN Bus adapter.

Nope, its an AN21-U, a totally different unit, there is a thread on XDA for it.

Is your dongle one that is compatible with these units ? The front USB ports are USB OTG and can act as host and slave, have you tried the front one ?

MTCmusic does exactly what you want, you swipe to the left for the track listing - the opposite way youd swipe for the source of you music/folders. The track list is very narrow though, it was in the MTCmusic app on 4.2.2, but someone did 2 modified versions (think it was Dark Alex) within the first few months of the thread, one with a wider list so you can see more of the writing and one with the track list embedded into the back ground of the app, no one has done this for the KK version though, althoug someone did request it, you could try yourself - its a case of modifying the xml of the app.
