Just flashed the KLD firmware on my HF.

Noticed a nicer BT menu and dialpad.. Not sure but I feel the radio reception's better too!

The interface is...okay! Hope it was somehow customizable tho.

Can't move or change the buttons on the bottom.

Since I flashed the kgl 1.86 MCU along the update.. I finally got the button lights to turn on/off like they should. So that's a real plus for me :)

Anyone tried the RM firmware on the HuiFei's? Would be down to try that since they've got a nice interface as well

I have had my unit since March.I am using it everyday and so far I had not big troubles (I do not have amps, though). I have run it during summer at around 33ºC and it worked fine.

Issues I still face:

- radio reception is bad. I found out I bought the wrong antenna adapter. I will change it soon and update

- voice is bad on the android side. I cannot use google OK or anything like that. It just does not get me.

PS: I have a KGL.

Hey Guys,

My unit works great however I would like the radio to receive messages from my phone (Whatsapp, text etc) and be able to respond to it through its interface.

Do any of you know a good app trick to let it work in such a way?

Thx in advance :good:
[MTCB Android Head Units Q&A] tomato18:
you will need a few apps/plugins put together to get it working.

1. Tasker (Main app) (installed on phone and car)

2. WhatsTasker (Tasker Plugin) (installed on phone)

3. AutoRemote (Tasker Plugin) (installed on phone and car)

4. AutoVoice (Tasker Plugin) (installed on car)

how this works:

1. WhatsTasker in phone intercept incoming Whatsapp message.

2. Tasker sends the message to your to your car via AutoRemote

3. Message display and reads out in the HU.

4. You then initiate AutoVoice to listen to your reply. (you can set it to display/read out your reply before confirming to send it)

5. AutoVoice convert your voice input into text and send it back to your phone via AutoRemote.

6. WhatsTasker then sends the whatsapp message out from your phone.

For SMS, emails, etc you will need another Tasker plugin called AutoNotification. AutoNotification works pretty much the same but u will need WhatsTasker in order to send the message out from your phone.

Thank you for your answer.

I did try to set the SWC in the factory settings but no success :(

I have a SEAT Exeo from 2011 which is identical to the AUDI A4 until 2008 (B7). The dropdown for the Can-protocoll selection has an entry for Audi A3 and A4 but this on did not work. I tried many others as well, none of them worked. Can anybody say which is the right selection? Unfortunately I did not check this before I flashed the other rom.

I also tried to install the Xposed framework and the MTC module. There it is possible to set the numbers for the can messages. However I do not know what woud be the correct setting. Could someone who has an AUDI A4 post his settings for the SWC (and possibly MTC)?

Any oppinions on how to restore the nandroid backup?

Does the nandroid backup include the MCU as well?

I am going to give it a go.

Found a unit made by AiRoad company on Ali express which has RK3066 A9 Dual core chip.

Just wondering if anybody has dealt with this company?

It is so frustrating that most companies focus for Left hand drives so volume is on left side of HU.

I live in UK and very few HU have right hand volume knob but could not find one for RHD with RK3066 A9 Dual core. :mad:

[MTCB Android Head Units Q&A] artaxcc:
I bought my unit from them. Got it within a week, they where helpful in the beginning (when i hadn't ordered) and afterwards they became a little uncooperative. My unit came with the holes in the wrong place on one of the sides, which made the mounting brackets incompatible. I ended up drilling extra holes and everything is fine now.

I think they are up to par with the rest of the Chinese stores.
[MTCB Android Head Units Q&A] makkan00:
Thanks for the feedback.

I hope I do not get the same problem.

Have you tried custom ROM in your HU?
[MTCB Android Head Units Q&A] typos1:
Someone found that their antenna wasnt plugged into the radio IC internally, have you tried looking inside ?

Also some people have said that the KLD firmware (not the MCU) improves BT mic functioning, radio reception and overall volume levels, maybe you should give it a go ?

I m in the UK as well, but I kinda like having the volume on the left, I ve not seen any with the volume on the right I m afraid.

RGB LED

---
[MTCB Android Head Units Q&A] typos1:
AFAIK KLD do not do RGB LEDs - I have asked for them but they say they cant do them.

As your car has CAN Bus, its that that is likely to control the illumination so you d need a CAN Bus adaptor.

If your supplier isnt answering then open a dispute saying the item isnt as described because you cannot use it properly with you vehicle as it did not come with a CAN Bus adapter. If your vehicle doesnt have red LEDs that is another reason why it is not as described.
[MTCB Android Head Units Q&A] typos1:
Really ? If I d bought one and it had the wrong colour LEDs and no CAN Bus box so it didnt work properly, I d be opening one !

You could add RGB LEDs in theory, if you can find someone to supply them and youre very careful de-soldering the old ones and re-soldering the new ones, but might be quite a job.

For the "nice" "fancy (two-way) interaction between car and head unit", obviously you d need a CAN Bus adapter.
[MTCB Android Head Units Q&A] makkan00:
Good to see UK fellow member here.

I have bought another Chinese HU which has volume on the right and it is working brilliant.

Its only that I came here to hack that HU and saw potential in this unit therefore planning to change it to this one now.

I like the old one as its brilliant (Except iGO is not giving any volume out and radio reception is poor compared to OEM radio).

But this unit seems slightly better and I am thinking of going for 1024X 600 resolution but fearful that icons might be too small on that resolution?
[MTCB Android Head Units Q&A] typos1:
Theyll make the icons bigger on the higher res ones, to compensate.

What unit have you got currently ? - an AN21-U (Mstar processor), or maybe a WD8801 derivative (Telechips processor).

I like to change the volume with my left hand as its always nearby due to changing gear.

You could possibly modify one and put the controls on the right, from what I ve seen the buttons and knobs are on small boards that could be moved, especially if you get one that has only one set of controls on one side.
[MTCB Android Head Units Q&A] makkan00:
Honestly not sure which one I have but its this one

http://www.aliexpress.com/item/4-2-...pacitive-multi-Touch-Double-2/2034957287.html

The seller stated that he would help to get the volume back by sending me iGO software and that has not happened in last 48 hours.

Tried to search online but there are so many versions of them so confused which one will work.

[MTCB Android Head Units Q&A] agentdr8:
I see. So when the unit starts, if none of the inputs are in use, what should the mode button do? Just launch the 1st source? There's no good way to determine if there's a source in use or not; the MTC server basically does foreground application checking to decide what source is being used.

If you have a chance, enable debugging within the module settings, reboot. Then when it comes up, before selecting a source, hit the mode button. Then provide me the error.log from Xposed Installer->Logs.

Thanks for the answer. I checked that long time ago, when I installed the HU the first time, and it was ok.

I have changed the adapter and now I have much better reception. :)

Regarding the mic, I had bad quality on the android side, and acceptable quality on BT side...

[MTCB Android Head Units Q&A] Orannous:
The function of the source button is to initiate the source input selection and switching between them by pressing it repeatedly. If none is running originally, perhaps it should detect that and launch the first one (I understand that it may not be able to detect the if input is running or not) and on subsequent presses switch to other ones.

How can we enable debugging? thanks.

Buttons layout coded in an app ?

Ok, this is a weird thing.

I installed KLD-2.01 on my HF with HF MCU 2.03. At the beginning everything seemed to work fine. Then, I used Titanium Backup to restore all my apps. What I got was the old launcher (HF style). The settings layout was the same as in the HF.

I rebooted it. It got back to KLD style, but this time the buttons no longer worked. SETUP launched AV-IN, pushing volume did not BACK, ... and so on.

Is it possible there is an app that manages all these ?

Update: Now it happened with KGL 2.03 FW and MCU. A reboot apparently fixed it. ideas ? ...

Recovery Mode

I received the instruction below from vendor in regards to entering the Recovery Mode on my unit (I've already tried all the instructions on the first post of this thread and none worked).

"Turning according to the power button, and then press the reset few, after hearing the noise three entered recovry."

I was wondering if you could make sense out of this. I've attached the picture of the unit to this post as well. the small reset button (RST hole) only resets the unit and I tried pressing it few times but it just beeps and resets.

I will try now the KLD V2.01 firmware + KGL MCU 1.86 on E46 HuiFei unit and I will get back with the results.

Anyone who already tested this, how does the wireless work? Any drops?

LE: I installed it. It works but I don't like the launcher. The resolution is a bit better, radio reception seems slightly improved and the sound it is about the same as before. So, for me I will go back to KGL V2.01 + KGL MCU V1.86.

With the KLD V2.01 and also with KGL V2.03 + MCU 1.86 i have a problem with the EJECT button. Instead of pushing out the CD it just switches between HOME and DVD.

---------- Post added at 09:04 AM ---------- Previous post was at 08:58 AM ----------

Thnaks.

I got it to work finally. Actually the volume knob does nothing. the poer button is the small SRC/on button next to CD.

I had to press & hold the SRC & RST button for couple of seconds (unit status doesn't matter because the SRC would reset the unit anyway). Then release the SRC, and unit will beep three times. and then release the SRC. The unit is shut at this time. pressing the SRC again would start the unit and boots into recovery mode.

Using the recovery I could initiate an upgrade of MCU & also restore to original factory (which I accidentally did).

- Would you guys recommend installing the moded TWRP on this unit (as per first post of thread)? because that's mostly for KGL. What is the worse thing that could happen?I need a compatible backup/restore utility installed.

Thank again.

I will try to extract the KGL launcher and put it over the KLD firmware and see how it goes.

The modified TWRP is for headunits using the RK3066 chipset, which all of these units are. It isn't KGL specific.

I'm not sure what exactly the steps would be to restore the factory recovery if something went wacky with TWRP; I do know that you can't utilize the update.img/mcu.img packages to update once you install TWRP (there are other ways to update).

Yay - first soft brick!

Playing around with the framwork-res.apk.

I could not get it back into bootloader in the car! I knew I could when it was out so I had to pull it out again :(

Went into bootloader no worries then - Think its the battery connection being permanently connected - will look at that. **update** The power button needs to be pressed while powering the unit on from the battery connection (not just by turning on the acc switch) So you need to pull the fuse for the battery connector (yellow wire) and hold the power button while you put the fuse back in. Tricky in my case because the fuse is under the bonnet.

Downloaded my faulty system.img - fixed it on my PC and flashed it back. All good.

So this gives me more confidence now (after a few tense moments)

Problems with USB auto-unmounting ?

Hi,

I have had some problems with the rear USB ports in my unit (does not matter which, I tried with both, same result). Here's the issue.

The first time that I plug a usb stick, everything works flawlessly. I can read the usb, copy files, listen to music straight from usb. If I remove the USB, I get the notification of "unexpectedly removed". When I plug it in again, it mounts correctly, and I can even see the files with File Explorer. But, after about 1min or so, or when I try to access one of the files, the USB automatically unmounts, and I can do nothing with that usb anymore unless I reformat it, or I do a factory reset to the unit.

video: http://vimeo.com/91176112

If I leave the usb plugged in all the time, turning on and off the radio, it works fine. There is no problem.

But, if I keep the usb in and turn off the car, and then immediately put the car in ignition (so that the radio stays on and does not turn off completely), I get the very same error, and renders the usb stick useless for the unit (the pc can still read it without problems).

It seems the unit (my unit at least) does not handle well unexpected removals of the USB. Any idea how to fix this?

I contacted keylo, the solution I got was to try with another usb. I did try with two other usb sticks. One (Kingston), had the very same problem. Another one (brandless usb that I got as a free-gift on a course), which did not have any music file, had no problems at all and I could plug and unplug it as many times as I wanted.

All USBs were FAT-32.

BTW: If I connect the usb to the front USB port, none of this happens.

Summing up:

Front usb: no issues.

Rear usb ports:

- 1st time connection, no problems.

- If unexpectedly removed, then the usb auto-unmounts every time and is useless for the unit, unless reformatted or factory reset the unit.

Tried with:

- 4Gb LG stick (with music and data) --> problems

- 16Gb Kingston stick (with data ) --> problems.

- 1Gb brandless stick (with data) --> works fine

I need a crack apk dev. Anyone out there?

*** The keys to the city is in MTCManager.apk or MicrontekService.apk on older Roms. ***

If you decompile it we can code changes that will fix the Brightness issue, the Loud settings holding and even making the device stay on for any period of time after the acc power is turned off.

What I am having trouble with is re-signing the apk and getting it working after making changes.

Everytime I try to re-sign it says the same application is signed with a different key. If I replace the app in /system/app it just doesnt start. This stops the touch screen and audio. You can replace the file back by mouse and reboot to get it going again.

So anyone up for the challenge? Happy to post changes and test the attempts :)
