Yes i have a JY. But the wierd part is,that it worked in the morning and 2h later not.i have the unit from december and havent had any problems with Sygic till now.I dont have a 3g dongle so thats a no go.
[MTCB Android Head Units Q&A] CARRisma:
That is strange. I previously had a KD and it worked fine. But it has never worked properly on my JY. It will only start if a 3G dongle is connected. I suspect the dongle is providing some sort of location data. I know of one other person here who had the same problem. Have you changed any Android settings lately or installed anything new? Please let us know if you find a solution.

Where is the CAN Bus settings ?

Thx.

Thank you. Actually, I have tried 2 Logitech models. They both are detected as a camera by the Android system. However, the viewing apps do not show anything other than a black or pink empty screen.

I still believe it could be something about settings. Where was that settings that you made about fps, resolution etc. ?

Thx.

My seller not answer my emails for a long time now, so it looks like I have to buy a canbus decoder. Can you upload a photo of the "new version" canbus decoder? Or at least can you tell me the model number and revision? Thanks!

This is a great thread and has been very helpful to me with my KGL unit, so thanks everyone involved!

I've joined the forum to post that yes, I'm having the same problem. I have submitted a ticket to Sygic but they haven't replied as yet. I'm wondering if this will be fixed, or are we left with no navigation software that is compatible? (TomTom doesn't seem to work?).

Im still using IGO which came as default with my Pumpkin KLD unit

Changed the voice to an upper class british lady and she guides me around beautifully :p
[MTCB Android Head Units Q&A] JamesNorth:
Yes, I suppose that is an option - also checking out Route 66.

In any case, it does appear that clearly, this version of Sygic with the black screen (despite activation) is a real issue. The other thing is that with the immediately previous release of Sygic, I found that I could not download TTS voices/implementation. With this current version, I can download them and they're installed and ready to go - but my maps are black!

So you need an antenna booster. Does your car have a power lead in the base of the antenna ?

I think what he means is that he has downloaded and installed your KLD MCU 2.47 and he found it was not 2.47, it was 2.49 !

iGO still not getting signal in background

I purchased a Pumpkin unit last week and installed it. I'm having many problems, but I haven't finished reading and researching to resort to bothering all of you yet. But I believe I have tried everything for this problem and have not had any solution.

My iGo Myway gives the usual "GPS Signal Lost"' when iGo is in the background. I have added the following to the sys.txt;

[gps]

location_net=1

location_gps=1

accuracy_workaround=1

background_navigation=1

In fact, "background_navigation=1" was already there. (I also tried the version with semi-colons (no idea what they do), but that did nothing)

I have also changed every setting that I could find in the head unit's Settings. Nothing seems to have any effect. As an aside, iGo also cuts the music whenever it does anything. Again, this is despite me changing settings.

At the advice of Pumpkin, I reset the system. This caused me to lose iGo, but I finally found out how to reinstall it (with the same symptoms).

Is there some other step that I am missing or anything else I can try?

EDIT: How can I be certain that I have the KitKat version of iGO?

Thank you.

Oh, the other main issue now is that the radio volume on "1" is almost as loud as I want it to be. On "2" is is too loud. Is there a setting somewhere to change how strong the signal is so I can get all apps at a similar strength?
[MTCB Android Head Units Q&A] ga!nusha:
If it is the sound in general and not radio only it means that your car has an amplifier. If that is the case it means you need to use the HU's preouts to connect to the amplifier instead of the harness ones. If you search the forum you will find a tutorial posted by me.
[MTCB Android Head Units Q&A] NYCAR:
No amplifier, and it appears to be just the radio App that is the culprit (I cannot be more specific, since I haven't done much testing since the reset). In any case, I'd prefer that the head unit's volume be way down so that 50% of max is what is comfortable instead of 1% of max. It allows for a lot more control. Thanks for the quick reply.
[MTCB Android Head Units Q&A] typos1:
Have you gone into factory settings and looked what the volume levels are for each source ?

[MTCB Android Head Units Q&A] NYCAR:
GPS issue is my main concern, so I've been working on that. I did go into the amplifier part of the head unit's settings and turned everything low. That helped enough for now. I'll look at individual apps and volume levels later. Thanks.

bluclik steering wheel control

I have a KLD 4.4.4 from pumpkin and so far it's working well, but I don't have factory steering wheel controls and wanted to add that with the bluclik Bluetooth steering wheel control unit.

The HU shows the bluclik as "available" but won't pair with it.

I've paired the HU with my phone and obd2 just fine. I've tried removing the other Bluetooth devices and that didn't help. My guess is the problem is that the bluclik is seen as a keyboard...

Is there a way to get this to pair, or some other aftermarket steering wheel control that works?
[MTCB Android Head Units Q&A] typos1:
I dont think your ll be able to use it as the BT module is different on these units to what it would be on a tablet or phone which have built in phones and no facility to connect to and control other phones. The BT on these units is effectively a built in car kit which you wouldnt be able to connect a key board to, although it is possible to connect a BT OBD devioce.

You could try a BT dongle and see if that works, cant remember if someone has tried that or not before, but a thread search should throw it up if they have.

Usb Digital TV Dongle

Hi all,

I was facing some issues on last week. I plugged some gadgets on USB (pendrive, TV Dongle) together and smell something burned and starts a smoke. I found a person that repair this issue. He told me broken an voltage regulator. And this is happen because USB can be work least than 2A. And USB TV Dongle uses 9A. He advertise that I can´t connect the TV dongle anymore. It does make sense?

When I removed the unit to repair, I note that USB cable has stripped part showing her metal mesh. Now I don´t know if this causes the burn problem... If this mesh touched in a car metallic part (ground) and cause a short circuit... Do you have an opinion? Can I tested TV dongle again?

Otherwise, I will have to buy a wifi TV receiver and spend more money.

Best regards,

Thiago.
[MTCB Android Head Units Q&A] typos1:
Sounds like there was too much current which melted the plastic sheath on the wire.

Try using the TV dongle with a powered USB hub instead. Also check the specs so you can find out what the ampage really is.

the volume will work without any fuss.

You will need to install the car-service1.3 app to specify the music app to google music or an app of your choosing for "back and forward". carservice will also allow you to reverse back and forward.

Also you'll need to have a rooted image , so you can delete or rename music.apk in the system/app folder to have it switch correctly when you hit the mode button.

Separate Forum?

Hey Guys,

It's pretty crazy that this forum thread has 11.000 post on 1100 pages.

It's really hard to follow or read through for a newbie as it's in one thread instead of having a dedicated forum with separate topics.

I've been following the thread 5 months ago and now would like to know what's new, but without having separate topics it's impossible to follow up.

Is there a way to open a forum section here on xda for this head unit where we could have separate topics to discuss things the right way?

If there isn't.. I would be happy to help setup a site with a dedicated forum on it.

---------- Post added at 11:28 AM ---------- Previous post was at 11:17 AM ----------

We have asked many times for a separate forum, no one from XDA has ever replied, no one will give us a separate forum.

Even if we were given a separate forum or a new site was started, then someone would have to spend weeks and weeks going through this thread and transferring all the info into separate forums, a lot of work.

It is not so hard to use the thread search facility to find information and there are usually only a few extra pages added to this every day, so if you read it every day it is not too hard to keep up with the thread, you can also book mark any pages that you may want to read again for reference.

There is also a thread on 4pda.ru, but that is long as well.

[MTCB Android Head Units Q&A] mrmrmrmr:
hi everyone,

please forgive me, I am a real newbie with these devices.

I checked read some of the thread but couldn't find related information to my device.

My device MCU says:

MTCB-YZ-V2.21R

Model: 12150115 (but this is changable through factory settings I guess)

Android:

4.2.2_14012015

Kernel:

3.0.36+

Build: rk30sdk-eng4.2.2 14012015

My Car is VW EOS (2010)

Now my questions:

1. How can I use a better software (for example Android 4.4.2) ? Should I change my MCU and firmware ?

2. Where can I find the appropriate images ?

3. I understand that I should use nandroid backup before updating my unit. But how shall I root my device to get a backup ?

4. Car's little screen behind the wheel shows track number when I play music. It also shows the FM frequency when radio is playing. But I would like to see the song title if possible. I was told to check "factory settings". I played with the CANBUS options (only the VW ones) , but only the "VW&Skoda (simple)" (number 1) is working with my car. And it doesn't get any song names on the little screen. Should I check other settings ? (which one?) , Should I try other CANBUS options ? (Audi etc.)

5. When I turn on the Air condition (digital) on my car , nothing shows up on my device. Is it also related to CANBUS ? Would this behaviour change with a different firmware/Android version ?

6. I am trying some USB cameras as a front camera (Logitech mainly) . It is detected as a front camera by the Android system. I check with the app Z-Device Test (which is available on the play store). It shows my camera as a front camera and shows many supported camera features with multiple resolutions. So the camera is detected as a camera. But the default camera apps on the device doesn't show any image. They show a black or pink screen mostly. How can I set my camera ?

I know, I have a lot of questions as a newbie. Please bear with me and don't get mad at me :)

Thanks.
[MTCB Android Head Units Q&A] typos1:
Your device is a "YZ" model, it has only been mentioned a few times before, we dont know who makes it, but the Android spec is the same as all the other units and the Android firmware can be upgraded to any of the (dual core) versions available in this thread and on the servers linked to in it.

As the first page says, you can ONLY use a YZ MCU, but AFAIK none are available yet as we have so few people with YZ units.

The model is normally listed as an "S07" on ALL versions from ALL manufacturers, I m not aware of this being "changeable" in factory settings and it doesnt really affect anything anyway.

You can find the images from the links on the first page.

You dont need to backup.

The MFD and remote HVAC display do not always work in all VWs, they are model and year dependant, if you have played with ALL factory settings (including non VW ones) and you only get what you are getting now then there is nothing much you can do other than wait for new YZ MCU updates or write your own app.

If you want to find out more about VW models and the MFD and HVAC display then use the thread search function - it has been mentioned several times.

Cameras have been mentioned many times as well, I do not use one at the moment so I cannot help, to find out about them you need to use the thread search function - I cant remember every time someone has posted about cameras, the dates and the content of their posts !
[MTCB Android Head Units Q&A] mrmrmrmr:
Thank you. So I can upgrade to dual core android firmwares (4.4.2) ? That's good.

You say, I don't need a backup but I am worried. So I want to have a backup. How can I do it ?

For VW models and MFD and HVAC display functions you suggest to search the thread. What search keywords should I use ?

The camera issue is most important for me now. How can I find information about it ?

Thx.
[MTCB Android Head Units Q&A] typos1:
You can root using the guide on the first page if you have 4.2.2 and then back up, if you really must but the is nothing to worry about - if it went wrong you would just download a copy the firmware from the servers linked to on the first page.. You want to upgrade to 4.4.2 when 4.4.4 is available ?

Use all the key words that you have mentioned already, to search for info about MFD/HVAC plus anymore that you can think of, just like if yo were searching for something on Google and you couldnt find it, think laterally. The same applies to the camera. All the info is in the thread, it is there for you to us as resource.
