Well, I don't know too much about *Iphones*, but the way I solved this issue on my android Phone was using 2 apps : Automateit and In-Dash Tether for Android (both are free).

Automate-it is used to force screen "continuously on" in the condition the BT becomes paired with the Headunit. The reason for this that for some reason, MY cheap china Phone has the odditiy that it fails syncing the Phonebooks with the car unit when the screen is off : it just refuses to do it without an error. My wife's (even cheaper) Android Phone has no such issues. The moment the screen is forced on, voila, the headunit gets access to the phones' phonebook and downloads it.

When BT pairing is interrupted (I leave my car), Automate-It is used to permit the Phone to switch the screen back off to conserve power.

Tethering is forced automatically by using the In-Dash Tether app, which guards the state of the BT-pair too, and switches the phones' Tether ON automatically when being paired, and switches it off when the BT-pair is ended. By the time the headunit has booted, this condition is already set and activated, so the car radio has immideate access to the net over my Phone and I can -for example- use Igo's "Traffic" system to download all the potential road troubles on my route.

By using these 2 easy to use apk's, I maximize my phone's battery and do not have to worry about manually switching stuff on/off when entering or exiting the car. Maybe something like this exists on the IPhone too ? Because running this kind of software on the radio is a bit unlogicall, the theatering permittion and setting has to be done on the Phone-side, not the headunit's side. Something IOS's "Instant Hotspot" functionality maybe ?

Why does everyone think that the work of Radio, Bluetooth, replacing logo, Wi-Fi and so on up to me? I'm in the firmware to change the graphical interface and advanced settings. All other questions should ask the Chinese programmers.

What is unit currently using? Can you provide MCU version and ROM?
[MTCB Android Head Units Q&A] typos1:
I dont see it like that because I edit it using FireFTP and it looks different ot just the raw webpage. I have tried to add it to the "description" column but I cant, I can fins no way of editing that column, in fact, it does not even appear when logging into the site using FireFTP to upload/edit :(

Video out only works with the DVD.

That is normally how things work, are all your buttons working correctly ?

You are in the wrong thread, you want the AN-21-U thread.

Stop keeping on at him, he does it for free in his spare time !!!!!! How about you google how to do it and do it yourself instead of making demands ???!!!

Open it up and check the antenna is connected internally.

Go into factory settings and play about with them - check the radio chip type is the same as your radio chip. What upgrade, MCU or Android ?

Malaysk cannot do anything about it because as he already said, it is the MCU that controls it, you have put the wrong MCU on your machine I think.

Bluetooth

Hello,

I have a KLD module for my Hyundai IX35. At beggined the quality of mic was very bad. I was remodel it (remoce capacitor and solder MIC directly to module). Now the quality is very good. But i have the other problem. When i make connection and conversation during that 2 sides speek in this same time, the receive not hear me. In my opinion the connection working like HALF-DUPLEX. The same when the receiver is out side and there are is a wind - the same situation - cut my voice.

This problem is in second station KGL my friend. I think it's problem all modules. Somebody have a idea to solve this problem?

missing half RAM

Hi all!

I purchased the Huifei KGL unit.

headunit

1. We hear about on the radio while traveling.

2. The player is frozen.

3.Pushing the reset button, but still crashed during a restart.

4. Finally, no longer wanted to start again, but the recovery has come forward.

5. I re-flash a new software for the player.

6. Flash succeeded, but then the player is slow, crashed and would not restart, just use the reset button again.

7. I ran a test program that written out, only to see 512 MB of system RAM instead of 1GB. (512 MB RAM missing!)

[IMG="missing ram"]http://dl-1.va.us.xda-developers.com/3/3/1/5/7/1/3/IMG_20150428_175634.jpg?key=xONL3Sbp89hRInyOKA1QoA&ts=1431778591[/IMG]

I need the core board, right?

The problem is, the original seller does not want me to send guarantees core board!

Only equivocate, to test out the device, though you can see that you do not have half the RAM.

Can you help me to know how to order core board?

Regards,

tboy72

Because I am fed up reading people asking for Malaysk to do stuff all the time, he has spent a lot of time making his ROM he has made it with different launchers and resolution for different people, he does it for free, he gets little thanks but a lot of people demanding he change things for them. Do it yourself or shut up.

I m sorry I dont think there is, it has been talked about before, although I dont think anyone has actually tried to make it work by modifying anything, maybe you could try something, it would probably require decoding the MCU though.

It is not a "problem" at all, the units simply do not support duplex mics, at least not as far as I am aware, you could try fitting one and seeing if it works.

Or you could also try NOT talking at the same time as the other person. :)

I have tried everything I can see on the page and there is no option to add in the description field, it does not show anything like the same in FireFTP, see below :
[MTCB Android Head Units Q&A] typos1:
This has been reported twice in the last month or 2, its faulty board, ask for a replacement from your seller, or send your unit back.

You could get a quadcore board, just email the companies, its not hard, or read the thread form the last few weeks.
[MTCB Android Head Units Q&A] typos1:
He already has replied and he said the same as me !!
[MTCB Android Head Units Q&A] tboy972:
Thanks for the reply.

The problem is the seller do not send the board by guarantee.

If you dont know what i said please stay away. Please read all messages that i write about logo.

I talk about logo boot animation .

MCU i put what i recived from from my saler.

Before and now light stay on. All another function work fine with both mcu version.

kgl saler say that this mcu version is for my unit.

About light i discuted with agentdr8 to make some think like dimmer backlight.

Thanks !
[MTCB Android Head Units Q&A] typos1:
None of that matters - have you gone into factory settings and checked if the radio is on the correct radio chip type - TDA7706/TEF6644 etc ? Have you made sure it is set to your region etc ?

Ok, Or I could put "Rooted Official" ?

It is hard to understand what you are saying, can you use google translate ? I was just talking about the MCU boot logo which Malaysk himself said he could not change.

[MTCB Android Head Units Q&A] typos1:
No probs :)

There is no picture in your post, but if you want to change the launcher it is in system/priv-app.

Thats a bit too big to fit in the box and they arent untouched, theyre rooted and a couple of other minor mods, DSA just wants an indication that they are the original ROMs as opposed to the ones has made.

We ll have less of the sarcasm, "specified way" does not make sense in this context.

Help!

Hello everyone.

Firstly, I must apologise - I have not read all of the 1260+ pages on this thread - I tried, but a couple of hours a night for a week and half a day today were simply not enough. Plus, not being a "software" guy I was struggling a little.

I need help.

My radio - ES9753EN-7-Pure-Android-4-2-2-Car-DVD-Player- Ebay item number 231226052920 - owned for a year and got fed up with the lack of Jellybean apps. It is installed in a 2003 E39 BMW 5 series.

Tried to update to 4.4.4 as per info on 1st page. Did not update MCU as 1) thought this was optional, and 2) version is MTCB-KGL1-V1.72 and I could not find any other KGL1's.

From links on 1st page, downloaded and installed "update_4_4_4_800x480_RK3066_19_MAL_11_05_2015"

No backup was made - searched store for "Nandroid", came across apps with lots of negative reviews and requiring "root access". As I said, I'm not a software guy and didn't want to buy software which gave a lot of negative reviews. Wish now I had, or had at least signed up here and asked!

OK, so installed 4.4.4, unit booted. Changed language from Russian to English, paired with phone for wifi / net, downloaded Waze, all good so far.

But...

No sound, facia buttons not working although volume knob does bring up the volume bar.

Steering wheel buttons not working.

No radio reception.

No disc eject (SWMBO informed me she had a CD in the drive - must be the first time ever and I didn't think to check!)

Turned off ignition, radio did not power off like it used to.

So I dug out a cocktail stick and hit the reset button.

Now the radio is, well, dead.

Help!!

Got a 4 hour round trip tomorrow with SWMBO, and will need some music!!

Some photos attached which may help with identifying stuff. Photos taken AFTER update.
[MTCB Android Head Units Q&A] boberek:
So you have the same "problem"?? I call this situation problem, because my factory station haven't this problem. I can talking with other person at the same time.
[MTCB Android Head Units Q&A] gnox:
Try disconnecting the power cables from the back of the unit - this bought back a unit with similar issues for another member.

If that workes - check canbus settings and radio setting in factory settings (pass 126) to see if you can get sound, radio back. A firmware reset can set these to defaults.

Could you please tell me how to go about placing the edited ppp file in there?
[MTCB Android Head Units Q&A] R4D3N:
It has to be formated to FAT32.

That's right, but Erisin is supposed to be a HuiFei unit. Please upload when you can the application and I will try to see if I can get it to work on my unit.

How can i post 15 sec video here? It's about this device problem.
[MTCB Android Head Units Q&A] typos1:
Most drives come with 2 usb plugs on the same cable, one is for power should the device not be able to power it on its own, if youve got this extra plug try plugging that in to another usb socket, that should give it extra power (the power only plug should be the smaller wire coming off the main wire).

Sorry if you know this, or yours doesnt have 2 plugs, just trying to help.
[MTCB Android Head Units Q&A] xrapidx:
Yeh. Do know. I think usb3 one wire is more standard... not a major issue though, it was a long shot.

There is also TireHawk TPMS and iTPMSystem.

Is anyone using their unit with just the side in RED wired to the vehicle, and have a working radio?

Its all I've connected to my vehicle - it has a ground wire. But I see the side in BLUE also has a ground wire, I'm wondering if maybe the antenna isn't ground through this side, but don't want to rip everything out again to check
[MTCB Android Head Units Q&A] R4D3N:
The blue connectors don't have any ground.
[MTCB Android Head Units Q&A] xrapidx:
I have a black loose wire labelled GND on the adapter - hence the question...
[MTCB Android Head Units Q&A] kwalsh24:
Alright, so instead of a factory reset I cleared the days and cache. That fixed the switching issue, but not the volume mixing issue, so it must be something with the apk itself. Nobody else experiences this at all?
[MTCB Android Head Units Q&A] redcrozzz:
I am only using the red side, and my stereo fm works. The blue side had a red and black connector for the reverse camera (red reverse power in, black ground). I just left the whole connector off, because I didn't need it.

Fyi, I have a Ford huifei android 4.2.2.
[MTCB Android Head Units Q&A] J0sh_FG:
Same here
[MTCB Android Head Units Q&A] Rog_82:
Thanks for the help. :good:

Update:

Disconnected battery and can now get the unit to power up again, although not with ignition on - have to press and hold the "SRC" button (long press on "SRC" was previously power on / off).

Wifi works

Bluetooth works

The two knobs work for their functions on rotate but press does nothing

All buttons do not work

Radio does not tune (is set to Europe - correct as I am in UK)

No audio... ever.

Only way to power off unit is ignition off and get the cocktail stick out and hit that reset button. (or climb in boot, disconnect battery)

Firmware reset (at boot) done, results same. Not played too deep in factory settings yet.

From the very limited knowledge I have from what I have picked up here in the past couple of days, I'm thinking the finger points at the MCU software, or integration between MCU and firmware?

Can't play any more tonight - the wonders of design of modern housing estates, my driveway is underneath a neighbour's property. Approaching 11pm as I write this.

Is there a way to launch and control the Pandora on your phone from the HU? I know that some Sony and JVC stereos can do this.

I am using your latest 1024x600 firmware with Regular Launcher. Everything is smooth and fast so farst, no erros and internet seems to be faster. Booting time is aprox 26 seconds.

Also, the sound seems a bit improved and the new Equalizer works very well and looks good.

But, I have a problem: with stock firmware, the radio reception was good, but now with this version the signal is very week and I do not receive only 1 or 2 channels.

First post been lurking for quite some time. Installed klyde unit this evening in a 2009 jeep jk wrangler. When turn key to accessories radio works no problem able to use everything. Problem is when I start the car I receive no signal message on screen and no buttons respond. Turn car back to accessory and unit fully works. I know it is probably something stupid on my behalf. Have spent last two hours searching thread for anyone who may have made mistake like me. To no avail. Bought unit from Eonon. Model #G2110ZV came with 4.4 have not rooted or done anything other than install unit. Have run wire for backup camera but not installed the camera yet plan on doing it tomorrow. Jeep had stock non amplified stereo prior to install. Used pac c2r-chy4 to talk to canbus. Jeep is stick and only thing I did was connect parking break wire from unit to ground so video would work while driving. Other than that all other connections were as directions stated. If any one may have seen this issue before and can help it would be most appreciated. I am grateful for all of the hard work of the people in this forum that helps the rest of us enjoy these units to there full extent.
