thats ok, im looking for your mcu yet... kgl.mtcd.px5.800x480 anyone?

when you get it, put that decompressed dmcu.img on your sd root

insert sd card in sd gps slot

boot in recovery mode and select apply mcu image from sd card or usb

and thats all,

pd. dont needa do any factory reset or whatever, just update your mcu since you flashed the wrong one

mcu has nothing to do with update/rom, since mcu is unique to your radio model (call it bios) and update/rom is for a generic group of radios (call it operating system)

call your seller for your latest mcu version!

I've seen it, it's still under sign. Yesterday it was available its firmware today no longer. I downloaded a DMCU MX 2.48 that says to be for: Px3, px5, Sofia Intel so is it good for us too? I want to be sure of this.

Anyone knows if these devices has issues with nova luncher?

After i installed it,seems the screen to change brightness instantly from time to time...like every 5 seconds.

[MTCD Android Head Units General] bettuccio:
I installed the MCU MX 2.48 now the Bluetooth no longer works. The front parking sensors do not work yet. I changed 3 firmware unsuccessfully! I wonder if it depends on the MCU or the firmware or I did not install the perfect Witson unit. Do the front parking sensors work for you anymore? Illumine I got something wrong about the mounting? The rear camera and rear parking sensors work.

Betuccio...please read.

Many times have been said that mcu ia compatible for same brand px3 px5 and Intel sofia while they were for mtcd units (and not to mix different brands).

You are putting in doubt everything and all of this has been explaibed lot of times

Take your time to understand everything of your unit mtcd by reading the mtcd forums (not only the px5 one) that's the way the rest of people ia learning and not asking the same again and again.

But the first thing to understand is that all the stuff here presented is not 100% reliable that works... everything has risk. If you don't want to assume the risks...just leave your unit as stock (as it was designed for the 80% of people. Developers and risky people is the 20%)

I installed the 2.48 on my witson Unit , everything works as expected, i had to revert back from malaysk rom to the latest GS rom, FM reception was a Lot worse, and dab was horrible under the malaysk rom on my witson Unit. Now everything is back to normal

Dear friend, precisely because the material is not 100% safe that a person needs to confirm from those already tried. If we miss something serious becomes irreversible without a recovery easy to get everything becomes more risky, so I prefer to ask and I'm sorry If I have been repetitive why not kill my unit! I'm not accusing anyone and I'm not complaining. Maybe you misunderstood my intentions. Hi, good day.

Hi guys,

Ok, I bought this adapter usb to micro usb female (https://www.amazon.com/Male-Micro-Female-Adapter-Black/dp/B009AWA3VK) , but when I plug the device (http://www.j5create.com/our-products/android/jud650.html ) , my xtrons don't reconize it : no message, nothing. If I plug the device on my Galaxy S6, all is ok.

Someone understand something with usb standards ? host or peripheral is a possibe problem with usb/otg xtrons unit ? other suggestions ?

Thank you very much for your helps
[MTCD Android Head Units General] user602:
I do not know if that dock will work with the xtrons unit, but according to the j5create website, the dock came with a "USB Micro B to USB 2.0 Type-A Cable." You should try that cable first. Adapters such as the one on the Amazon link don't always work for data transfers.
[MTCD Android Head Units General] myspac:
Thank you for your help. This "USB Micro B to USB 2.0" is to connect the j5 device (USB A) to mobile phone (Micro USB B):

- Galaxy S6 works perfeclty with

few questions [xtrons tb706apl]

Hello,

I use xtrons tb706apl.

Yesterday I installed Malaysk ROM. Great work, man.

But I have a few questions:

1) The application phone does not automatically synchronize contacts. Call log can not be downloaded manually. Is there any solution?

2) I installed Malaysk ROM 2.0, but I did not update the last MCU.

20170506 FW and GS MCU: (Thanks to [MENTION=1162516]karollos[/MENTION]):

Https://1drv.ms/u/s!AjrY0uqbW_kBgzg9tEyeqrEACCfT

Is it possible to only update the MCU when I have Malaysk rom?

3) Echo still persists. Is that because I do not have the MCU updated?

4) Is it possible to change the boot animation?

5) I read this thread ... But I did not find it comprehensible how to keep Tasker and other applications running after booting.
[MTCD Android Head Units General] semaj4712:
Noticed a problem today, I have a third party clock widget and everytime I start the car and the unit wakes up from sleep, the clock will not update the time. It does not seem to be working in the background. I am running the latest GS firmware rooted with xposed on the Nova Launcher. Anybody know why this is happening, there shouldnt be any battery saving features running is there?
[MTCD Android Head Units General] bm282:
Thought I would just add to the experience knowledge on WIFI on these units after reading ALL the related posts. I have marginal wifi connection to my WAP that is 15m away. Unstable and very poor speeds - if it does connect. Hard to get it to connect. Tried with and without security on the WAP. Made no difference. Tried 4 different WAPs of different brands. No difference. So I created a WAP at about 7m distance using a spare Apple timecapsule (connected by long lead to a Win7 computer in bridge mode to another WAP in the house) in my garage. Able to maintain good internet connection and got speeds around 5Mbps download - which was mainly due to throttling by the technique I used to get the WAP in the garage. Assessment - WIFI works fine if you have a good WIFI signal strength to connect to. Stable, usable speed and reliable. Managed to download all Spotify music to an SD card. Also moved the WAP right into the car, and apart from brilliant signal strength, no difference in performance. So my next step will be to change out the stubby 'antenna' on the back and put in a proper antenna (or 2) as others have done to see if I can get better distance. The WIFI connection as I created it was completely stable and not an issue even when I had Bluetooth connected. Its a generic model specific KGL headunit in a 2007 mazda 3 bought via Aliexpress.

Model is A-MEDIA Auto (1024x600 S)

Build Number px5-userdebug 6.0.1 MXC89L user.hct.20170307.175624 test-keys

The MCU firmware is MTCD_KGL_V2.43_4 Mar 31 2017.

I'm reluctant to change the firmware as everything seems to work perfectly. Don't mess with a good thing!!

And with the OBDII bluetooth device, I've checked a transmission error, so sending car off to service.

Good system this Android head unit!!!

Now all I need to be able to do is modify the apps in the MODE list so I can select the apps from the steering wheel!!

Thank you to everyone who has posted helpful thoughts/ solutions.
[MTCD Android Head Units General] Bose321:
Will this one work as well, with firmware updates? Seems really cheap (186 euro) and looks the same with the same CPU. Or should I just get a Xtrons or something? Have a Pioneer AVIC now and want to try out one of these.

PX5 unit loses date/time when disconnected from battery

I have Xtron PB7646BAP. Haven't put it in car yet, testing on tabletop. I noticed that when it is unplugged from battery, it loses date/time settings. Is this normal?
[MTCD Android Head Units General] leonkernan:
Yes, these do not have their own real time clock batteries and rely on the car battery connection to maintain the clock. They can update it by GPS after startup as well when the antenna is connected

Top right corner of the screen didn't seem properly mounted. Took the front off and there is a white plastic tab that had rotated away from holding the screen. Put it back in position and tightened the screw. Hopefully it's not going to reoccur.

Added external antenna to unit to replace original antenna. Will allow me to add a larger antenna in the future if I need it. The module definitely is NOT diversity. It's wifi/bt module rtl8723bu. I won't be able to test wifi until I get replacement firmware to fix my screen resized issue.

Quick question, is there an SD card size limit, I'm about to replace the SD card that came with my unit with a larger/faster one and would like to know size limit (if one exists). A quick google search failed me.
[MTCD Android Head Units General] wobbletop:
It's usually listed on the specs where you bought it.

Mine says 32GB max external memory.
[MTCD Android Head Units General] user602:
The specs for my unit state 32GB card limit with an 8GB max size per file. I am using a 32GB card now, for music.

I have also tried a 64GB card full of mp3 and flac music files, and it did not work well. There were so many files in it that music playback would stutter and the entire OS would freeze or be slow to respond. Removing the 64GB card immediately fixed the OS problems.
[MTCD Android Head Units General] halloj:
Why? The designer of course assumed that the unit will be connected to a battery 24/7. i.e. your car battery.

As mentioned earlier it will correct the time when powered up if lost due to a power failure.
[MTCD Android Head Units General] zimilaci:
I use the malaysk ROM and some of us requested some apps to be "whitelisted" in the MTCmanager.apk since then some of my apps are coming back automatically. Which is good :)

XTRONS TB706 APL : GS-PB Android 6.0 HCT_PX5_6.0(20170506）

Hello

Finally after 2 weeks of galley I just handed my Pioneer AVH-X8800BT, the Xtrons TB706APL to a problem with the wifi, either no connection and impossible to connect, or there are disconnections permanently, I use my share 4G + with my Galaxy Note 4, ditto with my Galaxy Note3, ditto with the box of the house. Yet when wifi works I have 62Mb in down and 28Mb in up.

The first objective is the use of waze without connection it serves no purpose.

I installed the various official XTRONS roms, and the wifi pb is very bad, like FM radio reception RDS, and echo always present for the correspondent during a telephonic call.

XTRONS Technical Service totally unable to answer correctly.

[MTCD Android Head Units General] ikerg:
Even buying a universal unit, if you specify to the seller that it is for a mazda they will include the maZda adapter.

Ask them if you need a can bus decoder for the swc and if they have one compatible I don't think it will cost more than 30usd.

I have a dasaita specific mazda cx5 headunit with the canbus adapter.

Other guy is now receiving a universal headunit with the canbus for he cx5 as well (he will inform us how it is behaving).

It is a high-quality Samsung class 10 card. I think the issue is the number of files and directories (not the size), which is why I said that the card was full of music in my previous post; over 4,000 files arranged by artist then album. I also have a 256 GB Samsung SSD with over 8,000 music files (the drive is not full) and the HU also lags and freezes when I use it; the SSD worked perfectly with my car's factory HU.

If either of you have that many files in your cards (or USB SSD) I'd like to know what file system you're using (FAT32, exFAT, etc.) so I can try again.

Guys,

i wonder if these various kgl-mcu updates floating around (kgl.mtcd.px5.800x480.20170509.zip and 1024x600 Version) are really any different from the dmcu version 2.47? where do all this different versions come from?

If I compare filsize and content it pretty much looks all alike and I can not find any update later than 2.47 anywhere else...

[MTCD Android Head Units General] bm282:
Thank you for the link to the 2.47 version. I've done a binary compare on all the .img files... 800x480, 1024x600 and the link you provided. They are all absolutely identical.

The differences are in the .ext files:

the .ext for 800x480 lists as "screen:2"

the .ext for 1024x600 AND the file you provided the link for are "screen:3". HOWEVER the 1024x600 .ext file ALSO has an ASCII "LF" character at the end - not sure if that would cause a problem.

(As I am a newbie to this, I guess I can surmise that the .ext file gives the screen resolution of the unit).

So thank you for the link - I'll use that one for updates to my head unit.

I though BMW use their own propriety system called I-bus.

In PX3 the steering wheel study app is unusable for us having canbus. Mtcd-tools is the only way to customize steering buttons

Yep, that's why you get a CAN interface with the wiring kit.... ;)

I knew that the first Canbus systems were used in BMW's and assumed it remained that way.

Is there any way of doing it without malaysks ROM. I have no other problems and no need to run his rom, I would consider it if he could keep the apps looking the way they were.

Hi I have had big problems with the radio reception on FM, it was much worse than the original radio. And not much fun to listen to in the morning, when I drive to work and get traffic updates through the radio.

My seller Iceboxauto was not very helpful, got no information from them regarding the bad radio reception what so ever, and if anything could be done about it.

But I finally worked it out, I went through different signal amplifiers, and a dab+ FM splitter nothing worked.

Not until I found out that my car, a renault Megane 2014 model has an amplified antenna that needs 12v through the fakra aerial connector, and my px5 witson unit does not supply it.

Then I bought this : https://www.amazon.co.uk/Aerial-Adaptor-Phantom-2002-Onwards-adapted-x/dp/B01AIAJCNC

Now my radio has an acceptable reception, this one is needed for VAG group cars(VW,audi,skoda,seat) as well, it works on PSA group cars (Citroen/Peugeot) And Renault/Dacia/Nissan.

I found out as well that a lot of these amplified antennas can not use a FM/DAB splitter as the amplifier built into the antenna blocks out the dab frequencies.

For some VAG group cars its possible to buy a different amplifier, that fits in place of the original, and alows the original aerial to be used as a fm/am/dab aerial with a splitter mounted behind the radio.

Now I am much happier with my unit, and it's nice to listen to the radio again without dropouts hisses and other unwanted noises.
[MTCD Android Head Units General] Bose321:
Cheers. Just ordered it. I hope I get through customs without an issie. I paid 188 euro. My worst case scenario price is around 250 euro, so still pretty nice I think.
