[MTCB Android Head Units Q&A] wokro:
Many thanks to all who did the work on the KK :good:.

Just came back from updating my Klyde unit in my Honda Civic Hatchback with the prerooted image.

The update went smooth although I had also this strange error message on the MCU.img during update. But in the Tablet info screen it shows version KLD 2.08 and Android 4.4 and MCU is working including CAN BUS SWC .

I like very much the new Launcher UI and Radio interface and the ability to have now Menu Soft Button and Multitasking Button. I tested so far a few apps like Musicplayer, iPod Interface with my iPhone 5s and Bluetooth Handsfree. Everything OK.

There are only two issues I came across during testing:

1) Torque

Torque App is not able to write to storage and does not find the bluetooth OBD dongle although the OBD dongle was found by the bluetooth app. I guess the issue with the storage write access is native to KK and has to be solved as described some replies above.

2) iGO

I use basarsoft iGO 9.6.29 which worked OK under 4.2.2. Installing and configuring was OK but when starting a route the screen is flickering every 2-3 Seconds, seems like it is doing so when screen is refreshed by the app.

Does anybody discovered this also? Maybe I have to reinstall or check the sys.txt. Please any recommendation is welcome.

Can anyone link to a good guide (YouTube?) On replacing the touchscreen on these? Mine is still not working with touch functions, so they are sending out a new screen, stating its easy to replace, but I bet there are no instructions

I have a JY unit, I've checked the ribbon cables, but there are quite a few!

It should be placed in the root folder of the gps sdcard. If it doesn't prompt for update within the android os, try getting to recovery and flash it from there.

---------- Post added at 01:12 PM ---------- Previous post was at 01:08 PM ----------

Kitkat removed the ability for non-first-party apps to write to the root directory of sdcards. Also, the restriction to only pair with OBD adapters named "OBD" still appears to be in place for the 4.4 image. I haven't tested whether or not my bypass in XposedMTC still works.

Haven't noticed this with iGO basarsoft, but I haven't started a route yet. I'll test it next time I go for a drive.

Problem with Steering wheel

I bought this radio http://www.aliexpress.com/item/Pure...-Tiguan-Golf-5-6-Bora-Magotan/1810659026.html and installed it on my golf mk6. I'm having problem with my steering wheel control. When i installed different music player like Google Play Music my steering wheel doesn't work. It works only with factory player. Is there any way possible i can fix it?

Thank you

Hi agentdr8,

I did the update to KK this afternoon, installed my apps from googleplay (torque pro, poweramp) and - of course - installed xposed framework and xposedmtc 1.2.8h. Active options are automatic dimming, mode-override and your ODB-workaround. After a restart of the HU I found the HU in a bootloop :crying:

Ok, I reinstalled the image, the apps und xposed, but now I use xposedmtc 1.2.8c (seems to be ok) - only my "ODBII" bluetooth-device is seen but cannot be paired.

Welcome to the thread. It might behoove you to read through the entire thread (even though it's >400 pages), as there's lots of things covered that you'll probably have questions about. At the very least, use the "Search this thread" box at the top first. This particular issue can be resolved with the Car Service app that [MENTION=5867075]KeiserSozeyFr[/MENTION] wrote.

i've searched and i saw that the matter is on Car Service. But pls tell me do i need only to install the newer Car Service or something else?
[MTCB Android Head Units Q&A] zorantoma:
For Igo you need a version for KitKat
[MTCB Android Head Units Q&A] agentdr8:
Sorry about that. I meant to take down that experimental build yesterday and put the previous version back up. I've backed out the changes and posted 1.3 as a stable release. It contains the OBD override and shouldn't cause a bootloop.

1.2.8c doesn't have the override for BT adapters, although yours being named OBDII should work by default since it starts with OBD.

Old post, but hoping you can help. Did your Audi have the twin Fakra connectors? My 09 Skoda does and I can't get them both connected (second one won't fit due to the first one being in the way) This might explain the really poor signal. Any other way to take it? I can get 1 or 2 radio stations
[MTCB Android Head Units Q&A] typos1:
There are no instructions, just use common sense, remove all connectors and screws, fit screen, re-connect everything, take photos before you undo stuff if you think yourll forget where things go.

Take your time opening the unit, the screws are real pain to not strip, so pick few extra from hardware store incase you mess up few, hmm.. i did :o

the screws are about 1/3"=8.4mm

All MCU versions that match the manufacturer are the "right" versions for your unit.

The MCU is constantly being developed and new or improved features arrive with most updates, its just a case of waiting until the Chinese fully develop MCU/CAN Bus compatibility.

These units cost peanuts compared with the less functional Android units from the major manufacturers (how much do you think theyd cost if a big name made them ? Easily twice as much I bet), so I m sure you can put up with not having HVAC messages on your unit (whats the point of this function anyway - the HVAC unit is inches below it and you can see any changes on that), not having door open warnings (you can can see when a door is open by looking at it !) and the very slight inconvenience of not having radio station and track playing info on your MFD (you can see the station and track on your headunit !) etc.

Just give them a few more months and I m sure more CAN Bus functions will work.

Hi I recently purchased a Erisin ES9753A unit for my BMW X5 E53 (2005) model car. http://www.erisin.com/es9753a-7-pur...s-obd-bmw-5er-e39-e53-m5-e38_p498.html#review

Installation went well and at first the Notification bar was working as expected with drag down to access the Apps tray and messages etc. HOwever the other day i noticed that the notification bar can no longer be dragged down, but all other areas of the touch screen are working perfectly. I dont think it is a screen fault but i have been through every menu option that i can think off to try to fix the problem all without success.

Does anyone have any ideas what the issue could be with my unit? I have installed the reverse camera function using a relay from the CAN unit "Reverse" Pink wire. Not sure if that would make any difference though?

It also means that when in the TV Tuner menu I'm unable to use the top menu buttons to re tune the TV tuner as they are in the top screen area that the notification bar would be in the Android system.

I've notived after installing XposedMTC on my KGL running the KK KLD firmware it now boots, wont respond to any input then goes back to the manufacturer boot logo indefinitely
[MTCB Android Head Units Q&A] agentdr8:
Yeah, I left some code in by mistake that was causing a bootloop. I just pushed a new version up to the repo that should resolve this.

I'm in the process now of reflashing my headunit to make sure everything is ok. Times like these I wish I had TWRP on there :|
[MTCB Android Head Units Q&A] lfelix70:
It Works, but....

It works, but I have not seen any difference yet, I have the KGL-7402.
[MTCB Android Head Units Q&A] kwalsh24:
Just upgraded my unit to 4.4, love it! Igo tts tho still doesnt work right sadly, so stuck with sygic, will try navfree soon and see how it goes. Used tomtom the otherday, horrible! I used it once in the past and it got me lost, so thought it was a fluke, tried it again and yet again it got me lost! So off that goes, back to sygic, but I do miss igo :(

Think this release may also help my screen issue, its almost as tho when my screen is cold, and it is trying yo draw a bright contrast image (like the grey on the old 4.2 radio app) it would mess up. With the new 4.4 everything has a different look, which uses darker colours, so it may help my issue.

for me it did' work. I lost the SWC and and all canbus functions exept turn on and off signal. Went back to MCU1.77 version and all is fine axcept the radio reception is awfall :( I heve contacted the makers of the unit(Winlink) but got no responce.

Updated OP

Hi Guys,

long time no write. I have been rather busy lately and could only check the thread a few times.

Finally I managed to get some free time and update the first post. I simplified it and updated links and info.

I have also installed KitKat 4.4.2 in my unit, I took the one with 3Gb of internal SDcard. At first I had the same problem of it not being recognised. I erased/formatted it and it worked.

I also had the problem with the XposedMTC 1.2.8h giving bootloops. I am gonna fix it now.

Please, if you think something should be added to the first post, let me know. I am trying to keep it as informative as possible. I might have missed some of the problems&solutions.

Special thanks to [MENTION=434511]agentdr8[/MENTION] and [MENTION=456516]typos1[/MENTION]

You are doing a great work
[MTCB Android Head Units Q&A] kwalsh24:
Sorry I had tomtom on 4.2. Likely have to patch 4.4 to read & write to the SD card as mentioned in privious posts.

Maybe try running the kitkat external SD patch and then try running tomtom
[MTCB Android Head Units Q&A] kwalsh24:
Oh you likely will need rooted for it to work properly, the patch software needs root access to do the modifcatio to the system

I would flash the 4.4 rooted firmware, run the SD patching app, then install and see if tomtom works.

Seems a bit drastic, as I ve said twice before, you could at least TRY Navfree or Be-On Road.
[MTCB Android Head Units Q&A] kwalsh24:
Does navfree or be on road work with tts? Or is it like igo and doesn't properly fade the audio so you canbus hear the voice commands ?
[MTCB Android Head Units Q&A] king_huzi:
Worked !!!

Instead of using terminal emulator i used system app remover application which was easier to use.
[MTCB Android Head Units Q&A] typos1:
I cant say if it worked with tts, I havent tried it.

But I do get perfectly working voice commands with Navfree, I removed Be-On-Road, cant remember why, think it was because I preferred the interface of Navfree, deffo not because it didnt work.

I m a huge open source fan (mainly cos its all about communities working together to improve software, without selfish, greedy companies getting involved, cos Android is Linux based it HAS to be open source or Google wouldnt be allowed to use the Linux Kernel, if it wasnt open source we wouldnt be able to do anything like the software mods weve done to these units without being thrown in jail or having a massive fine, can you imagine Microsh*t's response if we modifed Windows and then started distributing the much improved modded version !! ? Lecture over, lol).

I installed several open source nav apps to see which I liked best (there is also OSMandMaps and Skobbler) as they take up lots of space I kept Navfree and removed the others, if I find a problem with Navfree I ll re-install one of the others again.

These Nav apps are based on OpenStreetMap, which is open source as well, as it is open source any mistakes in the mapping can be corrected by the community for the benefit of everyone. Plus some, like OSMandMaps encourage users to modify and improve them :

"OsmAnd is open source and actively being developed. Everyone can contribute to the application by reporting bugs, improving translations, or coding new features. The project is in a lively state of continuous improvement by all these forms of developer and user interaction. The project progress also relies on financial contributions to fund the development, coding, and testing of new functionalities. By buying OsmAnd+ you help the application to be even more awesome! It is also possible to fund specific new features, or to make a general donation on osmand.net" (theres a free version and a non-free version of OSMandMaps)

Hi [MENTION=535343]all[/MENTION],

did anyone manage Torque Pro to connect with a bluetooth adapter under 4.4.2? The ODBII-bluetooth-adapter is paired with the system (I had to change the BT-PIN to 1234) but torque recognizes no bluetooth-device... the selection windows stays empty...

Markus
[MTCB Android Head Units Q&A] typos1:
Is your BT adapter named "OBD" ? Think it has to be to connect, search thread for more details.
[MTCB Android Head Units Q&A] maan2304:
It's named "OBDII" - and pairing is ok: it is shown in the phone-app-settings and in settings-bluetooth as connected. Only torque doesn't recognize any bluetooth-device.
[MTCB Android Head Units Q&A] typos1:
Oh, sorry, cant help then, I prefer to use USB to OBD for Torque so have no experience with Torque and BT.

[MTCB Android Head Units Q&A] wokro:
Hi,

so I have the same issue, Torque does not recognize my OBDII dongle. Today I installed Xposed FW and MTCService but it did not help. Torque simply does not see any dongle although it is seen in the BT Menu.

Also my problem with iGO has not improved. iGO Israel or basarsoft version show the same behavior: screen is flickering while driving (screen updates of map while driving).

In 4.2.2 it was OK in both versions I was not able to get tts.

Does anyone has a running version? in case, please post me you sys.txt and the version number you're using.

[MTCB Android Head Units Q&A] agentdr8:
I managed to get my BT OBD adapter to pair (named CBT.) using the override in XMTC, but like you, Torque doesn't see it. According to the OBD Adapter Settings page, Torque doesn't think the headunit's BT adapter is turned on.

I've thought about flashing a custom recovery, but without bootloader access, if anything goes wrong, there's no putting the system back to original form. And I'd probably feel a lot better about going that route if I had working adb/fastboot via one of the usb ports.
[MTCB Android Head Units Q&A] typos1:

[MTCB Android Head Units Q&A] parazit26:
Hi guys,

i have installed the pre-rooted 800x480 - 3GB data partition image and i need to say it's awesome! Thanks to everybody who made this happen!!!

I really like the new launcher and the radio app is gorgeous. RDS is working even better now and showing more text.

Sound has also improved, at least to me. With 4.4.2 it's also possible to install Navigon straight from the play store.

But i have also noticed two things. Number one is, you can't rearrange this five stock apps on the home screen and second has something to do with the XposedMTC. If you set a third party player as default and also set a "Mode" button on your SWC and you click through all modes, your headunit will go into this bootloop screen.

For all people that would like to have an easy way to adjust screen brightness, download "Gravity Box"(Xposed Framework is required) and set the option "status bar brightness control". Now you can adjust brightness by sliding to the left or right on your statusbar. Just make sure to deactivate dimming control in your XposedMTC modul. Also a nice feature is to disable the full screen keyboard. This will make it easier to search for address in your navi app for example. There are a lot of other tweaks that are maybe useful for someone. Definitely worth trying :)

I'm thinking in the problem with torque and odb-bt-adapter (you know: torque doesn't see any bt-device). I've read long time ago, that bt is handelt by the mcu (at least primarly) - is there a driver/app/"something else" in android, that connects android to mcu-bt?

You can change the 5 default shortcuts, but you have to click on the car "quick menu" on the left side first. Then you drag the default icons up to the top to remove them.
