Seicane are a seller only, there are no "Seicane" units, to find out what unit you have go to settings/about device, the letters after "MTCD" or "MTCE" will tell you who make your unit.
[MTCD  Android Head Units Q&A] LuNaTum:
Yes I know that. I have not installet/started the unit to get that info. The point was that have you seen other units that come with a pre-installed cooling fans?

[MENTION=6614105]Garfanki[/MENTION] , you can try my modded ROMs:

This ROM with Android 7 you can flash by Android 5 recovery:

And this ROM

you can use to return to Android 5.
[MTCD  Android Head Units Q&A] Garfanki:
Thanks Hal9k_,

must I have to wipe all data before flashing the dupdate or not? I actually have malaysk rom in my head unit...
[MTCD  Android Head Units Q&A] Hal9k_:
[MENTION=6614105]Garfanki[/MENTION], yes, wipe is necessary.
[MTCD  Android Head Units Q&A] DanB0y:
Android 7 on MTCD RK3188 looks very promising. Its runs smooth. I would like to see it without bugs and with microG, that would make an awesome room.

And USB Audio drivers in kernel ;)
[MTCD  Android Head Units Q&A] leonkernan:
The RK3188 has been stuck on an ancient 3.0 kernel since before Kitkat.

It looks like that hasn't changed and they've adapted Android 7 to run on top of it. I wouldn't expect any changes there.
[MTCD  Android Head Units Q&A] DanB0y:
Yeah I know.

I will keep my fingers crossed.

If they could at least unlock the kernel so we can inject some modules..
[MTCD  Android Head Units Q&A] Garfanki:
Thank you very much! I flash your Rom with success! But unfortunately wifi and bluetooth doesn't work... I missed something?
[MTCD  Android Head Units Q&A] Hal9k_:
[MENTION=6614105]Garfanki[/MENTION], you may need to check the wifi / bt module model in the factory settings. Wi-Fi / BT works for me.
[MTCD  Android Head Units Q&A] Garfanki:
Ok, I will try. I will let you know... Thank you very much!
[MTCD  Android Head Units Q&A] Garfanki:

As of now it seems that XRC units have this issue, however I have also seen XRC units without mic issue, so it's really confusing. If there is a compatible MCU for XRC, we can try that.

Can anyone let me know how I can go about installing a Honda version of this HU in to a Toyota?

Can I use a Toyota metra harness and personally crimp/ join the wires from the head unit?
[MTCD  Android Head Units Q&A] typos1:
The wiring on all these headunits is standard car stereo wiring, so yes it will work in the same way as any other car stereo would, you should check that each wire is going to the correct place on the car before you plug it in though.

[MTCD  Android Head Units Q&A] Hal9k_:
Android 7 firmware for public testing​

Changes:

Firmware completely deodexed

Internal memory expanded by 1 GB

Preinstalled root and SuperSU (request for granting root-rights works)

Added support for init.d

Removed "red text"

This firmware can be installed not only on a new board with 2 GB of RAM and on an old one with 1 GB of RAM using a bootable SD card.

If it's interesting to someone, I'll tell how. ;)

I invite everyone to test.

I'm interested in reviews about the speed of the firmware compared to the stock of the same version.

When installed over the stock, the user data will be automatically cleared.

The first boot takes 10 minutes. At this time on the HU screen will be the boot animation.

Download: Google Drive
[MTCD  Android Head Units Q&A] typos1:
Great, I ll test it asap, basically its a Nougat version of your Lollipop ROM (the best MTCD/E ROM) ?

For 1Gb devices, install as though unbricking a unit then, with SDfirmware tools ?

After installation on 1Gb units can we update to later versions as usual ?
[MTCD  Android Head Units Q&A] Hal9k_:
No.

This is a test (preview) version. It contains only those changes that are described.

The main purpose of this version is to collect feedback on the work of deodexed firmware in comparison with the odexed stock.

I'm wondering if there is a difference in speed in your opinion.

Yes.

Yes, as usual.

Does anyone know where to get the firmware of Android 7 or 6 from the Erisin (KGL) ?
[MTCD  Android Head Units Q&A] typos1:
Erisin dont just sell KGLs they sell units from several different manufacturers.

Any particular reason why you want KGL ? Is it the launcher ?

There are a few Nougat threads, I take it youve checked them all ?
[MTCD  Android Head Units Q&A] Hal9k_:
Yes, I'm looking for a new firmware with the KGL launcher and their widgets.

I found the version from August. But, maybe, there is a newer?
[MTCD  Android Head Units Q&A] typos1:
I dont think the launcher has changed and besides, I think the launchers are actually the same for all MTCD versions, they install on all versions at least, even on MTCB/C units.

If you really want to check take a look at the other Nougat threads.

Have you seen the Roximo launcher ? I think thats the best personally. Its the only one that has a proper, movable, multi purpose widget and it also shows up in other non MTC launchers, which can then be installed without loosing the usual radio/music/BT/AD2P widget functio0nality, something that couldnt be done before unless you wanted the cheap looking, separate, KGL widgets that date back to the dual core 4.2.2 units. Of course if you dont really use the radio and built in music it wont make much difference.
[MTCD  Android Head Units Q&A] Hal9k_:
I saw, but for a long time ago. in what firmware is it present ?
[MTCD  Android Head Units Q&A] typos1:
All Roximo units - Roximo are a Russian seller of Klyde units, they commission their own launcher, you are Russian arent you ? :)

I have several types, from several versions, [MENTION=4339055]pakidermo5000[/MENTION] recently modded them, made them faster and converted the Russian only menus to English, these version are better then the standard ones, faster and less irritating to the eye - Roximo added a green "Cardroid" logo that was awful looking. I have plans to further modify it so radio station name appears on the widget and not just the frequency, make the icons bigger (easier to use when driving) and maybe add the DAB functionality to it so the widget displays the DAB stations from the DAB module.

See this thread :

https://xdaforums.com/android-auto/...auncher-movable-radio-music-bt-t3388348/page3
[MTCD  Android Head Units Q&A] Hal9k_:
Thanks, I will see.
[MTCD  Android Head Units Q&A] typos1:
Cool, the modified ones are at the end of the thread.

They also work on the octacore units, I still havent finished trying to persuade you to help me get your ROM working on those yet, just havent got around to replying to your post about it as I ve been so busy . . . :)
[MTCD  Android Head Units Q&A] s.rahus:
Wow! This is a fantastic news, Hal9k_!!!

While you are already working on the new firmware, can you also take a look at the microphone issue on the XRC units, please? The issue is that the microphone on these units only work in the Bluetooth app (during phone calls) and not with any other app (voice search, google now etc.) The below thread has lot of info on this.

I have a PX3 1 GB of ram with android 5.1.1 head unit. Thanks
[MTCD  Android Head Units Q&A] typos1:
Have you tried other ROMs ? Cant remember if I asked that before.

[MENTION=5092263]Hal9k_[/MENTION] - this mic problem only effects Nougat XRC MCU units, but if you replace the SoM with an Octacore one the mic DOES work with other apps including Google Now, so we ve worked out that it is unique to XRC N units and not related to the motherboard

Probably rename it to dupdate, but if you have a 1Gb unit you have to flash it using sdfirmware tools, you do realise that ?
[MTCD  Android Head Units Q&A] Garfanki:
I only ask one thing...

---------- Post added at 08:34 PM ---------- Previous post was at 08:30 PM ----------

It's a big problem! Halk please help us!

[MTCD  Android Head Units Q&A] typos1:
I m at a total loss, I ve tried it over and over again on 2 units and I cant get it to work, I m wondering if he meant flash his older version from May first ?

edit: He cant have meant that cos the file has been removed.
[MTCD  Android Head Units Q&A] typos1:
Right, I ve got it - as soon as you see "Nougat" on the screen, eject the SD card and Nougat recovery will appear, you do not want to see "error" on screen or it wont work, it will boot to the Lollipop recovery which you dont want.

Mine wouldnt install Nougat from usb, so I put the ad card with the update in the GPS sd slot and it installed from there.

Yes, [MENTION=5092263]Hal9k_[/MENTION], its deffo a bit faster de-odexed, it would be faster still if if had microG and maybe similar sorts of "optimisations" [MENTION=5228031]Johny DJ[/MENTION]'s version of [MENTION=6041319]dsa8310[/MENTION]'s MTCB/C ROM has (he got rid of some stuff and with microG theres 470mb RAM free typically). :)
[MTCD  Android Head Units Q&A] Garfanki:
If I well understand:

1) I must eject the sd card when I see "nougat" on the screen and it would appear nougat revovery;

2) insert the sd card with nupdate image and from recovery update from usb.

Right?

One doubt: I remember that when I put the sdcard created with sd flash tool, I received error immediately without see nougat on the screen, is it possible? Or I wrong remember...
[MTCD  Android Head Units Q&A] typos1:
You need 2 sd cards - one made with sdfirmware tool and another with just the nupdate on, use the bootable sd card to get into recovery and use the one with nupdate on after youve got into N recovery to flash the ROM. The bootable sd card is just use for getting into N recovery nothing else.

---------- Post added at 10:23 AM ---------- Previous post was at 10:18 AM ----------

@Hal9k_ - you will get many more people using trying this if you open a thread about it. I m tempted to open one myself simply to tell all RK3188/PX3 users that Nougat is available for them, but it is your ROM and well it seems a bit rude if I do it at least without mentioning it to you.
[MTCD  Android Head Units Q&A] Garfanki:
Ok, thanks, I understand and I will try... The ROM is good? What are your impressions?
[MTCD  Android Head Units Q&A] typos1:
Yes, its good, I posted a comment about it earlier. The only thing I dont like are the radio/music /BT apps theyre not like the ones I had on my Nougat unit, but that is not [MENTION=5092263]Hal9k_[/MENTION]'s fault, it is either down to the ROM he based his on or maybe updates mean that all Nougat ROMs have these apps now.
[MTCD  Android Head Units Q&A] Garfanki:
Ok, thanks! However the sound is good?

Do you think future updates of this ROM by Halk can fix radio/music/BT, etc.?

[MTCD  Android Head Units Q&A] typos1:
Fix them ? I only gave my opinion on how those apps look, they work ok, you may disagree and like the way they look.

I will try and change them.
