unit identification

Can someone help me identify the maker of this unit?

www DOT ebay DOT com/itm/131230433783?

It seems to have internals of a klyde and a look like a Fei. So I am confused.
[MTCB Android Head Units Q&A] typos1:
The spec and rear suggest its a Klyde, the menus and homescreen suggest HuiFei, 2 out of 3 things are Klyde, so I d say its a Klyde.

Only 2 ways to find out, either buy it or get the seller to send you a pic of the "about" screen showing MCU version.

Does it matter which one it is though ?
[MTCB Android Head Units Q&A] ptclabs:
Hello,

Well I did buy one, and I have posted about it one page back second post. It has some problems also listed in that post. Mainly with bluetooth contacts. So I am guessing it will need some updating and I do not want to brick it.

Its MCU is MTCB-GS-V1.91

after more poking around, it seems it is a different manufacturer than the three normal ones. I am working with their developers now to fix the problems. Anything they send me I will post in the original post. If anyone wants the files they send for dev purpose please contact me.

thanks

Who is the developer for the GS?
[MTCB Android Head Units Q&A] ptclabs:
The name looked Indian to me, but they did not say, just an email.

I have found a lot of these units on asian sites with version 1.86. they were all complaining about the wifi dongle not working. I think they revamped them in ver 1.91 and made it internal wifi. The wifi works flawlessly.

I have received a mcu.img and a update.img file from the seller. Updated factory reset but same result. I think it was the same version that was on it.
[MTCB Android Head Units Q&A] booroondook:
Does anyone know which option of v.1.99 mcu.img is compatible with my KGL-7618 (Toyota Universal)?

kgl_1.99.zip archive contains 6 options of mcu.img. I tried to install "4" and "5" options, but after these updates SWC settings don't work, and front panel buttons work incorrectly.
[MTCB Android Head Units Q&A] dark alex:
Just wanted to refresh that. PLEASe partivipate if you haven'T done yet!
[MTCB Android Head Units Q&A] Dareksa:
No, button lights and buttons work like it should.

I have SWC connected in my Toyota Avensis and everything work OK.

My unit has only microphone problem, but I can live with it.
[MTCB Android Head Units Q&A] parazit26:
is there a can bus adapter in between your car and the headunit? Which mic has a problem, external or internal?
[MTCB Android Head Units Q&A] Dareksa:
No, my car doesn't have a can bus adapter. Problem was with internal microphone.

Now I cut off the wires from internal microphone and I use only external. Only minus is that I lost voice control.

Quality is better but not as good as it should be.
[MTCB Android Head Units Q&A] typos1:
I see, so looks like a Klyde on the outside, has a Klyde spec, HuiFei menus and homescreen, but its a GS version !!

What is the name of the manufacturer ?

You dont appear to know about the GS versions or how bluetooth works on these units, can I suggest you use the thread search facility to the right and read up about these things ?
[MTCB Android Head Units Q&A] R4D3N:
For e46 I received a new firmware, v2.01 which claims to have a fully operational unit in 17s, including boot.

I will test it and come back with a review.

I think the update should work on all devices, but I only have the right MCU for BMW.
[MTCB Android Head Units Q&A] kwalsh24:
That's awesome news, lets hope wifi is fixed, without having to use the older 1.77 kernel & that the firmware is soon made available for all units. Fingers crossed!
[MTCB Android Head Units Q&A] obekende:
Ooooh! that's awesome news! thks RaideN waiting impatiently for you review, if all goes well up the files to update my radio too! :fingers-crossed:

[MTCB Android Head Units Q&A] kwalsh24:
We could maybe try flashing the Mcu from the current release with this 2.01 and see how it works. 17sec boot time would be nice!
[MTCB Android Head Units Q&A] Skitals:
I added a 4 channel amp to my system, hooked up with RCAs, and it solved my popping issues. I still have horrible radio reception, I've tried 3 antenna adapters now. Does anyone know how to DISABLE the internal amplifier? Since I was having problems with it, I'm guessing it could be causing interference with the radio. I believed I read something about grounding out a pin on the amp, but I can't find it now.

This is of course assuming the internal amp isn't required for the pre-amp RCAs.
[MTCB Android Head Units Q&A] Navall_75:
I recently updated to 1.86, before this the GPS indicator used to show in the top left now it doesnt. Have i missed an option or is it due to the update?
[MTCB Android Head Units Q&A] Navall2:
If you have a Navall 2 (as I do) it should work.

I used the KGL1 version.
[MTCB Android Head Units Q&A] Navall_75:
Yes Navall 2, the GPS connects but the icon only shows on the top left when an app that uses GPS is opened it used to be there all the time so i knew it had signal.

The other issue is the hiss from the speakers, strangly it only happens when i connect to my phone via bluetooth.
[MTCB Android Head Units Q&A] zorantoma:
Set in clock settings to chack for time over GPS and you will have the icon showing all the time

180

There is no info about them that I can find. Even Mr. Google has nothing about them. From what I understand they sold some of the 1.86 units a while ago that had wifi problems. Then these came out.

Who makes them? no clue

I can find where he bought them from, but from the amount of sales staff the place has I think they are really just a reseller. I have done business with china for many years. MANY companies claim that they are making a product when they are actually just buying it from another factory. The gs does not fit with their company name, and I cannot find one that does.

MAYBE GS stands for Guandong Shenzhen the place where they are made, but I think they would have gotten their company name in there somewhere. So I have been poking around for a company with the name of Guandong Shenzhen electronics company, but coming up empty.
[MTCB Android Head Units Q&A] Boodro1:
I bought my GS off of ebay and they couldn't say who makes them or where to get updates from.

What Tts engine is everyone using? Anyone successful with tts working with their GPS app, I've tried svox & ivona but neither mix at all, also found that neither mix with radio OR SD playback, the only one that does is the non tts option in Igo, both tts in Igo & tomtom both do the same, not mixing.
[MTCB Android Head Units Q&A] Dangerous13:
Please tell me where to download the update for the GS version. My dealer also can not provide updates.

Thank you!
[MTCB Android Head Units Q&A] ptclabs:
Unrar it stick it in the gps slot. turn on it will see the update.Turn the volume down it pops real loud once. Do wana blow the speakers.

This is the 1.91 update for the 1.6 duel core 4.2.2 gs unit, and most likely others. I have not tried it on anything else as i do not own anything else. Must do a factory reset from the settings menu after install.

Use at your own whim and risk. It worked fine on mine and repaired the fancy widgets. Although it only gets location from wifi still. At least it works now. I still have the contact list problem. I would suggest a backup if you own an older model. GS ONLY

'member to hit thanks

ps if you are rooted it will unroot. The root procedure from first page still works on this version.

Since we cannot find the exact company name I would just call them Guandong Shenzhen version for now, or GuanShen Version. I know they are made there, and hopefully this will help come up with the company name. It will be part of the company name. They are sold through a rather popular reseller close to there also, but they are not making them so we cannot get to the "source" for info and report problems.

Once you do get to the people making the thing you can get in contact with the people programming it. That is when all the problems it has disappear overnight. The resellers usually do not care as long as it is still selling.

Alex from Ebay has been trying to resolve the problems. I think he is a good reseller.

[MTCB Android Head Units Q&A] R4D3N:
I updated the firmware to my unit. Boot-up seems pretty fast, SWC works good.

Buttons are always illuminated. I have to test the WiFi today and to measure the bootup time.

E46 V2.01 ------> https://www.dropbox.com/s/e0phgenhvxytma5/E46 KGL5 V2.01.rar?dl=0

Enjoy!!!
[MTCB Android Head Units Q&A] Navall_75:
So button illumination is constant not on/off with the headlights?
[MTCB Android Head Units Q&A] R4D3N:
Exactly, but I think it's an MCU issue.

If someone would have got all MCU versions, we could try all of them. I think with KGL1 it would work as it should, but for E46 I only received KGL5.
[MTCB Android Head Units Q&A] Navall_75:
The 1.86 i have works fine, WiFi works and GPS connection is better and illumination is as it should be. I think i will leave it till all bugs are gone from new updates.
[MTCB Android Head Units Q&A] typos1:
I dont think it stands for Guandong Shenzhen - all these companies are in Shenzhen, thats why "Shenzhen" appears in the name of most of them (Shenzhen Klyde, Shenzhen Kai Ge Le etc), their names appera to consist of one place name plus another name, not 2 place names.

I take it neither of you have bothered to read the thread !? - as you appear to be unaware of this post from a few weeks back:

Also, wifi problems on 1.86 are common on HuiFei/KGL versions as well, NOT exclusive to GS versions, again, this has been mentioned many times in this thread !

Lol, theyre ALL 1.6 Ghz, RK3066 DUAL core !

I only asked for the name of the company as this post suggested you knew who they were, who are their developers ?

I would assume connecting the RCAs would automatically disable the internal amp, you could try looking in settings to see if there is a manual switch. Maybe you have a duff radio chip, someone else had the same problem, cant remember who though.
[MTCB Android Head Units Q&A] Tomcsyy:
illumination

Hi all,

How can I set the brightness to the same when the lights are off and on? I don't want to have lower brightness if I turn on my light in day time. :confused:
[MTCB Android Head Units Q&A] typos1:
If you bothered to either read this thread, or use the thread search tool to the right, then you wouldnt need to ask, you would have found your answer !!
[MTCB Android Head Units Q&A] idr3s:
Got the v2.02 up and running with the KGL4 MCU. Boot up time was quicker, menus are a bit more refined.. Though the button illumination remains on all the time. Anyone know a KGL4 version without this prob?
[MTCB Android Head Units Q&A] lamjanus:

Well ok. Just to let you know who I am I am a importer for Chinese car parts to Japan, and I have been for many years.. I have found the company producing this unit, and it does not really make sense with their name except for the area. It took me a while though. If they had any other reason of choosing GS I have no idea what it would be.I am guessing after talking to them they are not really the ones who choose the name. Do I think it stands for the city. Yes I do. Is it part of their name. Yes it is. Would it make sense other than that? no.

Congrats welcome to China.

Does it make more sense for them to use the Indian programmers for androids? yes it does. They are very cheap and very good. I am trying to push them to get the problems fixed. When they do get it fixed I plan on selling them here.
[MTCB Android Head Units Q&A] typos1:
I often import using Chinese companies. I m now confused as previously you said:

"There is no info about them that I can find. Even Mr. Google has nothing about them. . . .

[MTCB Android Head Units Q&A] parazit26:
just installed 2.02 update.img + 1.77 mcu.img and 1.86 mcu.img both are working fine, no illumination issue. The only issue i have noticed or maybe i am just totally blind :), since 1.99 there is no menu for changing the button color. correct me if i am wrong.
[MTCB Android Head Units Q&A] idr3s:
Well I guess I'm going to try that out too!

Did you notice any WiFi drop issue using any of those mcu's?

About the button colour.. There actually is a menu and that probably reset to default I.e. hidden when you updated. All you have to do is go to factory settings (password 126)..hit the last menu and tick the RGB option.. Save and go back to the menu and you'll see the "elements" option back in the menu.
[MTCB Android Head Units Q&A] kwalsh24:
Installed 2.02, think may have found the first issue.

unit on, radio apk playing, car not running, start car, typical thump from speakers, and no sound after, have to close out the radio apk to restore sound :(

Also think rds isn't working.

This wasn't an issue in privious releases. Likely will downgrade back.
[MTCB Android Head Units Q&A] parazit26:
thanks, i have forgot to turn it on! i don't use wifi so much, but i can tell that the 1.86 was stable and i didnt have any wifi issues so far.
[MTCB Android Head Units Q&A] idr3s:
Need to ask you something though.. When you were trying out different mcu's .. Did u have to flash the update along with it. Because I would like to install just the (1.86) mcu but I don't want to go through the pain of installing all my apps and settings all over again. How should I do this with the least amount of restore work?
[MTCB Android Head Units Q&A] dark alex:
Hi

anybody has KGL-7683?

If yes could xou make screenshots of all Factory Settings screens? Mine has reset upon last update... probably my fault... Tried a wrong image :(
[MTCB Android Head Units Q&A] kwalsh24:
Definitely downgrading, 2.01 & radio.apk freezes up whenever I start the car with radio on. Lets hope they fix this in the next release!
[MTCB Android Head Units Q&A] elcolombia17:
I think the most stable is 1.86
[MTCB Android Head Units Q&A] kwalsh24:
Yep, going back to 1.86, will battle my GPS apps to get the best one working, tts or no tts. Even tho I really like tts when driving in unknown areas, tried sygic but the version I have only does full screen so it blocks the android bar
[MTCB Android Head Units Q&A] parazit26:
I have always used the update.img because when i got the unit i immediately updated to 1.86 and been running this version for almost two months. when the 1.99 came out i wanted to reinstall everything so i used again both images and because i had nothing relevant installed yet i did the same with the 2.02.

What i noticed with the 1.99 and 2.02 version is that the LOUD option doesn't need to be enabled after every boot.
[MTCB Android Head Units Q&A] ProfessorKnox:
Just a friendly reminder: Did you enable RDS in the factory settings menu?
[MTCB Android Head Units Q&A] Skitals:
I believe there is a workaround for installing only the MCU... I think I read you can use a corrupted update.img that doesn't pass the validation test so it will skip it and only install the valid mcu.

You can also use titanium backup to backup all apps and settings. On a fresh install, sideload the titanium apk and you can restore all apps/settings.
[MTCB Android Head Units Q&A] kwalsh24:
I always check for rds & rgb led, both are enabled on this rom by default, has the same issue with the 1.95 mcu
[MTCB Android Head Units Q&A] idr3s:
Yep I do use titanium backup usually but since I did two upgrades today (1.99 first then later 2.02 once it got posted) while recovering all apps and settings each time .. I don't think I'll do anything with the unit for a little while.. Let's see maybe a more final/stable version comes out soon enough.

Thanks for the info though.. Might use this sometime [emoji4]
[MTCB Android Head Units Q&A] R4D3N:
For e46 (ES9746) I updated to V2.02 firmware + V2.01 MCU.

The good:

-fast boot

-a little faster while multitasking

-WiFi and 3g good, no droping issues

-settings menu more organized

-in DVD/CD mode, the selected song looks better than in the old version

The bad:

-button illumination always on

-radio still not very good (but unlike other users, it doesnt freeze or any issues, works exactly as before)

I am trying to get igo to work on my device. Whenever I tap the icon it says put the SD card in but it is already.

[MTCB Android Head Units Q&A] sprfly:
Ok I will give it a try. When you say download do you mean from the play store? Sorry new to the android scene. Then delete the "content" folder from within the iGO folder on the SD card. I am leaving the sys.txt and save folder? Will iGO just know to look for maps on the SD card? Thanks!
[MTCB Android Head Units Q&A] zorantoma:
thera are forums like this one for igo navigation.ther you wil find all the files and versions for our units. Just use your search engine ;)

For first run try leaving the sys.txt and save file from the new version. If it does't start delite those files and try again.
[MTCB Android Head Units Q&A] R4D3N:
In order for iGo to work, all the files and folders have to be copied or directly to the root of the SD Card or in a folder called iGo.

Otherwise, it won't be able to read those files.

BTW: Latest iGo Israel works very good indeed.
