KGL unit with internal and external mic

Hello!

Do you have any resolution pattern for KGL units with both internal AND external mic. How do i isolate internal and external mics?

For me the working of EXTERNAL mic is more than enought Is there anything i can do without opening the unit complitely?

Does this meaning cutting the C32 capacitatior?

Best, Jukka

Yes,but if the radio was playing when the unit turns off,then on boot starts mp3 and not radio.

[MTCB Android Head Units Q&A] marco.lav:
.. From what I understand, but I have not checked the circuit,

the capacitor C32 connects the microphone to the BT module.

I do not know how it is connected to the external microphone, because my UH is not equipped with external microphone.

You could try removing the capacitor c32, but without breaking it, so with a good desoldering station, the c32 that seems to be the capacitor that connects the internal microphone to BT

if everything goes wrong you have to replace

Try following the tracks of the external microphone and see where it is connected.

RDS and radio preset buttons

Has there ever been a solution to not having the RDS info scroll across the preset buttons? That is the only thing I do not like about this radio. Only solution I found was to turn off RDS.

In the radio app it shows the station frequency in large font in the middle. Right below it shows the RDS info and looks good. Right above and on the preset button it scrolls the RDS info, sometimes it mixes parts of the RDS feed and you get some strange character combinations. If there would be a way to eliminate that top line or at least the preset button that would be awesome. The XPosedMTC does not seem to work as far as keeping the presets from changing.

I know there were a few threads scattered through the 760+ pages but I never seen an answer

Where is my recovery mode?

Hi,

I've had two of these radios in the past and was able to root and flash them without issue.

I got a new one in August and I want to reflash it with one of Condu's ROMs but no matter what I try I cannot get it into Recovery mode.

I've tried all the different scenarios but all I can get it to do is, when it is starting, print

"Recovery Start"

and then

"Recovery End"

But clearly it is happening too fast for it to be loading new code off the GPS card.

Anyone have any other tricks to get one of the most recent generation KGLs into recovery mode?

Can´t get into recovery mode

Thanks for the advice. Unfortunately it seems, that I can´t get into recovery mode. Neither with pressing the reset and power knobs nor through the "recovery Boot" app. When trying both, the screen becomes black and stays black.

I already re-install the firmware with update- AND MCU- (2.09) image on the GPS-SDcard´s root folder, but no success.

Or the Quick boot app.
[MTCB Android Head Units Q&A] HuiFeiFan:
Thanks for the responses. I tried the reboot apps but I haven't been able to get Root on this one yet so they don't work.

I tried the Root Master program 2-1-1 but it didn't seem to work and, of course, its in chinese so it is a little tough to tell what is actually happening there.

I was hoping that if I could boot to recovery I would be able to flash one of the ROMS that is pre-rooted.

I am wondering if there is another button sequence to get my version into recovery.

[MTCB Android Head Units Q&A] ProfessorKnox:
Fixed station name on soft buttons: In order to have the button text fixed would mean that the radio app needs to store the displayed text persistent just when the button is assigned to the radio station (long press). That was at least the way how it was solved by my previous WinCE HU. As a consequence the app code would need to be modified to provide this functionality. The issue itself is caused by the providers mis-using the intended static content of the PS (Programme Service) RDS element (max. 8 characters, usually used for station name) by dynamically modifying it.

Scattered RDS text: This is caused by the fact that RT (Radio Text) is transmitted and repeated as sequential text blocks of 4 characters per block with offset information (max. RT length = 64 characters). Under non-optimal reception conditions blocks may be lost. If RDS text changes rarely, this is not a problem. Again this is caused by the providers, changing the RDS text quite often - and a problem of the radio app re-building the Radio Text from scratch (i.e. deleting the whole text) when the first element is received instead of just overwriting the received element and keeping the others until its element is received.

Scattered text on soft buttons: Same issue like Radio Text: Information is sent 2 bytes wise. Under non-optimal receiving conditions elements may be lost and thus not updated, leaving the old content side by side with the new one.

RDS text line could easily be removed by modifying the skin - how to do skin modification was explained some times in this thread.

Removing station name text from button is likely not possible by just modifying the skin only. I would think reassignment of the pre-set assignment with the frequency by the station name is performed by the app -> thus potentially modification of the app code necessary.

Hope this helps.
[MTCB Android Head Units Q&A] djfuji:
change frequency

anyone can modify the restoration of the dials stored in memory each time you change frequency?

For example memory 1 have saved BBC Radio I scroll in the country and frequency changes automatically but memory button 1 is not updated the change and still kept the original frequency.

also if you do a manual search and a station that you have saved appears you select the same or equal frequency is automatically updated to do all the car Radio.

Which requires 9 volts to power fully, my unit is only supplying 7.5 The company I bought from is sending a new board so hopefully that will fix the issue, but it would be nice to have reference for troubleshooting if the new board does not correct the issue, or if any other issue arise.

The seller sent me a new Canbus adapter for my unit, and now I have SWC!!! :) I upgraded to Condu's 4.4.4 ROM and I have got to say... if you were afraid to do the upgrade, it's 100% worth it. The sound quality is greatly improved over 4.2.2 on my Klyde unit, and radio sounds 200% better. I know others have said it in the past, but it's very worth it. Wifi is more stable for me too.

The only outstanding issue I have with my unit is that, as others have pointed out, it seems to drop certain frequencies to the speakers, especially in the mid-range. 4.4.4 helped with the new equalizer, but it still seems to be missing certain sound frequencies. I have a factory Jeep amp that connects using the amplified speaker outputs, so I'm wondering if that is to blame...

I also had the infamous "engine noise" through the speakers when I was using the PAC adapter, but those sounds are gone using the Klyde Canbus adapter.

I did pick up an unlocked Huawei E355 3G modem/wifi hotspot dongle, but it only picks up 2G here in the US on both AT&T and T-Mobile. It will need a powered hub and won't plug straight in to the HU (the power/wifi lights flash on and off, it doesn't supply enough power but works in a USB phone charger port as hotspot). If someone has a use for it, shoot me a PM because it's basically garbage to me... 2G can't even reliably stream a song on Spotify. Cover shipping from the US and it's yours. It uses HSPA+/HSPA/UMTS (900/2100 MHz) and EDGE/GPRS/GSM (850/900/1800/1900 MHz).

Again, thanks everyone for the help this far! I hope to start writing some apps/tweaks for it soon.

4.4.2/4

The music player app for HF4.4.4 looks the best. Functionality of playlists and scramble play is gone as everyone knows. Has anyone made this app with a bigger title window yet? I see a red one around, but really do not want red and i think it is the 4.2.2. HF one anyways.

I broke one of the legs on my GS attaching the mic on the bluetooth module. So I desoldered the whole thing and ran a copper cable to get everything hooked back up right. I think I figured out why people can hear themselves repeating themselves on the other end of GS models like an echo. The last pin on the BT module is called NC. The only thing I could think of is noise cancellation. (silences the microphone when other side talking) It goes absolutely no where on the GS motherboard, it just dies right there. The HF I have while internally looks like a mess, does not do this.

Miracast

Hi,

Just to telling you that the miracast sink (as receiver) works on our unit. Mine is tha Eonon GA5153(Klyde).

Ihad to install "Miracast Player" application and test it with my Lumia 930. It's a bit laggy and buggy but it works !!!!!

Had anyone some info on WV display between the speedometer and the rev counter? Because sometimes it worksand I see it but sometimes not.

I'm searching a way to inject maybe some data and add the GPS direction. I saw that here map is displaying direction in the status bar so maybe we can grab this events and direct it to the Display (called MFD in VW)

Blackscreen - can't get into recovery mode

Hi folks, I'm slowly getting desperate. After flashing codous 4.4.4 I had that prpblem, that when shifting in reverse thr screen went black and stayed black when shifting back.

Same thing happens when turning on the head lights.

Also the first boot logo doesn't show up. Only the customized car logo comes up after a while, then the device is booted.

Darkalex told me, that it is a flashing fault and I have to re-flash my MCU (2.09 for KGL).

When putting the MCU.img on the GPS SDcard root, nothing happens. I already flashed a new hardware (boo's 4.4.4 for KLD) but again the mcu.img was not even recognized and the problems stay also with the new firmware.

Trying to get in recovery mode for mcu flash failed. Neither with combination of reset and powet button nor using apps like recovery boot work. The screen becames black and stays black. Pressing the reset button leads to the booting described above.

Can anyone please give an advice how to flash the mcu another way?

Thanks

[MTCB Android Head Units Q&A] TooBusy:
android-caraudio.com, Aliexpress, eBay, and hundreds of other online stores provide a great opportunity to some "smart", mostly Chinese, guys to make money selling crap to naive buyers.

Most people in this Thread are already aware of that, and many have already had similar experience. People who are looking for quality, reliability, warranty and value for money buy brand name units, such as Alpine, Kenwood, Pioneer, Sony, etc.

These non-brand units are an expensive hobby. They initially seem to be much cheaper, but when you add hundreds of hours, multiply by $x that you would get if you spent that time working, trying to fix problems and get everything working the way it's supposed to...

And when the unit dies prematurely, you buy another "toy", possibly from a different seller or even a different "model", and the hobby continues...

Many people in this Thread got initially excited about their new toy, but got progressively more disappointed over time, only to disappear completely after a while. Guess what happened!?

There is a handful of people who've been active here for a while. Some of them keep their units on the desk, not in the car. This is all about Android development, as you know, so you can understand that.

There are also new people coming on board all the time. Some are in the first group: bought a unit naively believing it's a good unit, reliable, good value for money. Some are in the second group: they just enjoy fixing/improving - Android development. Which group are you in?

Good luck with getting a replacement or refund! Most people get neither.

MCU images

Hi all,

I have a KGL-7620 unit and am still on Android 4.2.2 with MCU v1.77 . Overall I'm happy with the unit as it does (did, because the power amplifier died for some weird reason and killed my speakers) perform as it should. BT OBD dongle is working, GPS (Igo) does it's thing, Wifi is ok, Radio tuning (could be better) is ok. That's all I use atm. I might considder soldering a new external mic connection and a wifi antenna, but never change a thing if it ain't broken still stands.

Since some of you are blown away by the Android 4.4.4 image but never mention which MCU version you are using, I guess v1.77 is still ok?

Is there a table out there with an overview which MCU version has/does what, eventually in combination with which Android version?

I know some will say "read the thread", but for me it's impossible to follow the thread daily and remember everything what is written here (wow, I'm a normal guy after all :p ). Thumbs up however, the real geeks are helping us out every time and beyond.

I thought that now is a good opportunity to upgrade while I have my unit in the lab to replace the Amplifier ic.
[MTCB Android Head Units Q&A] RobNeru:
Thats exactly what I did. But any to try to get into recovery mode ends up with a blackscreen.

Do you have an active speaker adapter for your Audi ?

I dont understand how you will be "out of $500" - if you bought it on credit card you will also be protected.

If youre using KK (4.4.2 or 4.4.4) then you can only root by flashing a pre-rooted image form the repository.

It could well be to blame - if youre connecting the speaker outputs to an amp then your ll need a special box to un-amplify the signal before it sends it to the amp, if you dont do this then its going to sound rubbish because its being amplified twice.

Sorry but this post is absolute rubbish.

Generally, with the exception of a very small number of failures (usually down to poor build quality, but fixable), these units are fine and superb value for money, they just havent been developed quite as much as they could be, in this thread we sort that.

Many of the components used are actually from major manufacturers and the similar products from major manufacturers just cannot touch these for functionality - they lock down they devices and you can barely do anything with them (ie Parrot Asteroid, Pioneer App Radio).

Most people "disappear" from the thread once they have done all the modifications that want because they dont need to visit the thread any more as their unit is working how they want. What do you expect, people to post everyday with things like "I m still happy, my unit is working ok" ?

And if people "dont get a replacement or refund" then it is their own stupid fault - ebay and Alibaba/Aliexpress have comprehensive buyer protection plus credit cards also offer buyer protection, if someone buys their unit from somewhere without buyer protection or in a way that does not offer it, then they only have their selves to blame.

If you havent anything positive or helpful to contribute, then dont bother posting.

3G Sticks doesn`t work

Hi together!

Since a view weeks ago i bought a Erisin ES9746A. Its for the BMW E46.

After the second day i flashed the Coudus 4.4.4 KGL 800x600. It runs better than the OEM Software :D.

The MCU is the KGL5 2.09, send directly from Erisin.

The only Problem what i got at the moment is, that the 3G Stick isn´t working for longer time.

If i join some area with less signal, the connection getting lost and didn`t come back.

Only if i put the Stick out & in again, the connection joined again (with all Sticks the only way to get access again).

I tried it with different Sticks, also the Huawei E 1750, ZTE MF667 and also with older Stick.

Best working is the ZTE MF667, its connected as ETHERNET, so there is now signalstraight sign, only a doubled TFT in the Top. The Connection get lost after view time.

With the Huawei E1750 some Apps didn`t get Internetaccess, Wlan Hotspot doesn`t work. On the 4.2.2 i can Access the Internet with HSDPA, on the 4.4.4 with max. 3G.

Same Problem also with the OEM Software and an older MCU.

Hope you got some Information/help for me and big sorry for the BAD english :silly:

Try any MCU version you want for your unit, try the latest and if it gives problems or you loose functionality then try another version. What car do you have ? Are you sure it doesnt have a built in amp ?
[MTCB Android Head Units Q&A] peti007:
Copy the update.img and mcu.img on an SD card's root folder, place it in the GPS slot, start the head unit after 1-2 mins there will be a popup message (there is a new update.img) where you can start the update process. The MCU will update too!

There will be black screen for 5-10 mins, please wait!

Other method:

When you step in the Recovery menu you can blindly update the head unit. The screen will blank, but if you enagle Key Tones in Android/settings before, you will hear beeps.

So when you are in Recovery with black screen, the head unit beeps. Then press the volume knob shortly there will be a short beep. Now press and hold the volume knob till a longer beep. Wait 5 minutes and the head unit will reboot with the new firmware
