no no look at the console center of mercedes when you are in the Android area does not work anything even the volume, I only work the steering wheel controls
[MTCD Software Development] typos1:
This is the same for all units.

So move the antenna from the Merc system to the Android system.
[MTCD Software Development] Mighty_X:
If I upgrade from Android 5 to Android 7 will I still have the iGO maps working which are used to have? Thx
[MTCD Software Development] caturano:
in my android box as in no one else I saw there is no antenna socket for this I do not understand how the radio can work
[MTCD Software Development] caturano:
Sorry I had forgotten the photo of the box
[MTCD Software Development] LordAnpu:
As I said this device don't have radio module, it use onboard radio. Check if installation was proper, especially harness connectors that connect original system with android box and check antenna connector to your onboard radio.

Before android box installation radio worked?
[MTCD Software Development] caturano:
the radio on the Android box has never worked Indeed it was deactivated and I reactivated it via factory settings with regard to the wiring I have no idea if they are wrong as I have all plug and play, but maybe in China they are different from Europe and the seller has not the faintest idea
[MTCD Software Development] LordAnpu:
I meant if onboard radio worked before?

I asked about harness because if onboard multimedia system is not connected to android box radio will never work.
[MTCD Software Development] typos1:
You ll have to re-install it.

It may well get the radio from the built in Merc system as has been said, I think you need to do some googling, including looking at how other aftermarket headunits work on your car.
[MTCD Software Development] iRcKenny:
Like i said some post ago, and another forum member talking on similar HU for BMW, the unit is acting like a "man in the middle" this mean the unit is using all factory radio capabilities adding the android capabilities and [MENTION=9485051]caturano[/MENTION] had enable the radio functionality where originally was disabled.

Radio, CD, DAB+, ect etc are from main Mercedes Unit and they are intercepted by the new Android HU.

This is all writed in all Aliexpress, Made in China, MarketDIY, HiSupplier product advice about this unit.

My opinion.
[MTCD Software Development] caturano:
it could be as you say, however, as already said, when I'm on android area the whole Mercedes system does not act only the steering wheel commands! as for the search on google I could not find anyone who made some changes to this system in fact I was hoping that on this beautiful forum someone would find it. Could you help me?
[MTCD Software Development] iRcKenny:
Sorry, i cant, dont have a similar HU on my vehicle and never seen any of your HU installed. Maybe some other forum members can be more helpful
[MTCD Software Development] caturano:
we hope that some soul can help me
[MTCD Software Development] newneo_1:
Ok, sorry. I read the android 5.1.1 method but my problem is the GPS card slot don`t work ok in my Erisin. :(

Any other solution for me? Thanks
[MTCD Software Development] masri1987:
Hahaha I was gonna say MCU ain't gonna make a diff

I'm gonna recover my system to nougat, then change dupdate to nupdate and flash it within n recovery

I think [MENTION=5092263]Hal9k_[/MENTION] needs to holla at us and let us know wassup with this so we aren't losing our collective minds trying this
[MTCD Software Development] VampireXz:
Stuck

I tried installing and got an error stating that the

n

update.img was not found.

It appears that the firnware tool changed the img name to

sd

update.img .

Tried to change the name to

n

update but the V7 boot doesn't start. In the V5.1.1 version he is looking for a

d

update.img

At this time my Head unit only starts in recovery mode since it formats the partition prior to checking if there is a good image to flash.
[MTCD Software Development] masri1987:
I had to place the nupdate file manually after the firmware update tool did it's thing.

Also I hate that it formats the partition prior to checking image to flash because if it fails you literally have to start from scratch
[MTCD Software Development] VampireXz:
OK, Nailed it.

Added both img files (sdupdate.img and nupdate.img) and tried again. Same error.

So I changed it to the other USB cable and it started installing.

It went black after the installation and didn't budge.

So I made another installation. Black screen again.

But after reset it worked. :)

Nice rom . Very smooth. Excellent job. Thanks :D

How do I get the Torque app for this rom? The prior one was somehow tempered while connecting to the OBD2 reader. ( I couldn't get it to work with a Torque from the Google Play Store).

Do we need a special app also?
[MTCD Software Development] masri1987:
Explain precisely what you mean by "changed it to other USB cable"... Trying to figure out what you did exactly..
[MTCD Software Development] masri1987:
Changing dupdate to nupdate didn't do anything
[MTCD Software Development] xtcr1st1:
Hello, is it me or the ROM doesn't have the lock screen option from 5.1mod?
[MTCD Software Development] typos1:
I m going back to N, I only wanted the L recovery to change the MCU - the N recovery is too intelligent - it wont let you flash a different MCU and I need to cahnge mine - went to HA but radio doesnt work, so need to go back to MLT, only L recovery lets you do this.

So its only you loosing your mind, although I appreciate that doesnt help you. Of course as its falshed the L ROM but wont boot it, I may not be able to get back to N either :eek:, havent tried yet, so I may be doing my head in later as well !

Didnt think it would.
[MTCD Software Development] kehadamus:
1. I tried many programs for HD video clips. 1 gb ram is not enough for nougat. Sometimes freezing. 5.1.1 smoothly.

2.The system does not power up without removing the gps micro sd card.
[MTCD Software Development] typos1:
If you have 1Gb RAM, its advisable to ONLY use the microG set up.

Did you wipe data/cache manually after installing ? If not try that.

Also, if you left the bootable sdcard in you should remove it - its only used to get into N recovery if you have an L unit.
[MTCD Software Development] TvBIFI:
not working for me either.

after choosing microg the screen goes black and thats it

Disabled google and google framework the buttons in play services have been greyed out. so i deinstalled them via titanium backup.

but no luck the screen goes black an remains in this state only reset helps
[MTCD Software Development] VampireXz:
I have two USB cables coming back from the head unit that I slip behind the car console so that I could connect some pens .

The instructions talks about inserting the pen in to the USB 1. Probably the unit doesn't mount USB 2 during recovery.

[MTCD Software Development] typos1:
Try downloading the update again.
[MTCD Software Development] Codyphillips48:

I can say I already love this. My torque pro app widgets

Are staying on the screen and not going ghost like the stock one after restarting the head uint. Huge thumbs up
[MTCD Software Development] typos1:
I ve been trying to use the Torque widgets for a boost gauge for years - but you cant set the calibration of the gauges as you can in the main Torque app, so my widget boost gauge has a scale that goes into the hundreds but my car is running 1 bar boost, so the needle moves a few mm at max, been p*ssing me off for ages. I ven emailed the dev a few times but no reply.
[MTCD Software Development] Codyphillips48:
Lucky for me my gauge is in psi which is are standard unit of measurement. It tops out at 24psi which is about 4 psi over what my car will top out at. I ordered this seicane unit that fits my mk4 golf and the stock room wouldn't keep any widgets after shut down and restart. They would like ghost away if you would long hold where they were then the trash can would pop up . This is definitely worth send some money to support. I'm a diesel mechanic and I love being able to monitor my important gauges at all times and with a 2 hour drive to work I wanted a radio to watch YouTube mobdro and Showbox. I love the fact that the radio doesn't show the radio station call signs and just shows the channel. Thanks again for getting me going in the right direction with the SD problem I had
[MTCD Software Development] typos1:
You can change what method you want the gauge to read in, in settings, so it should show me the bar equivalent of 24psi when I set it to bar, but it doesnt, its some stupidly high figure if bar is set, the calibration is all wrong, pretty sure it wasnt right when I changed to psi and kpa too. In the main app you can set what numbers you want the gauge to read to.

BTW its not a Seicane unit - Seicane are sellers only, the letters after "MTCD" or "MTCE" will tell you what unit you have.

The "ghosting away" was probably due to the 1Gb RAM your unit has and the fact that Google services takes up so much of it.

You mean RDS isnt working ? Thats a fault, or RDS is not enabled in factory settings, cant understand why you wouldnt want the station showing, but if thats the way you like it. :)

PS - psi is only "standard" in the US nowadays, everyone else uses metric ! Youre from the US I take it . . . or maybe the UK and, um, over 50 ? Lol. :)
[MTCD Software Development] Codyphillips48:
Yup I'm from the good ole USA.

Hi [MENTION=5092263]Hal9k_[/MENTION] and all,

I have a px3 (800x480 W) with an XRC MCU, which is the latest for my model, and a custom ROM (although that doesn't really matter for this issue). I have a problem a really weird problem on bluetooth, that happened while on stock ROM and now on this custom ROM as well:

- If I'm starting the call, people hear me with a 2-second lag. I talk, wait 2 seconds and only then receive an answer. It's infuriating.

- If it is a received call, it doesn't happen.

Anyone with the same problem that can help me? Or anyone with some kind of idea on how to solve it?

[MTCD Software Development] TT_Vert:
Is there anyway to intercept the MCU button commands like mtc-keys used to do? It works w/ MTCB units but I cannot get it to work w/ the MTCE MCU. I tried mtcd tools but I couldn't get that work in the least. Some say mtc-keys is working for them but it appears it isn't intercepting anything for me while looking at logging. Basically I want to configure single/double click of navi, src and volume press buttons. I've discovered the key input #s for them but no love thus far. Any help would be very appreciated.

Thanks

Dave
[MTCD Software Development] typos1:
Have you tried the Grasser app ?

Have you read the thread about 725 BT modules ?
[MTCD Software Development] DarkSorcerer:
I have not, but I will now!

---------- Post added at 02:00 PM ---------- Previous post was at 01:04 PM ----------

It seems MD725 is an integrated module and that everyone that has problems with it must desoldier the module and buy a COMFAST one. Was that what you were talking about?

Thanks!
[MTCD Software Development] typos1:
I think only type2 MD725 needs to be replaced, but that thread has solutions for some MD725 problems, do you know which type you have ? In [MENTION=5092263]Hal9k_[/MENTION]'s Oreo ROM thread theres a script that you can run in a terminal to find out which type you have.
[MTCD Software Development] DarkSorcerer:
Maybe I saw the wrong thread.. I only find some things for PX5, while I have a PX3.

https://xdaforums.com/android-auto/...velopment/bluetooth-usb-dongle-t3684383/page1 - this one talks about dongles and how they (don't) work with MD725, unless you unsoldier the chip

For those who had been asking about T9 dialing. You can use ExDialer and choose MTCD Dialer when asked what program to use. You can then use that for T9 dialing.

[MTCD Software Development] typos1:
If your MCU does not start with "MTCD" or "MTCE" then no, "S190" sounds like its a development of the S160 units, try the Android Headunits General forum.

There are several different types of processor used in MTCD/E units, what is yours ?

All this is clearly written in the first post, mind.

Hi! Does it happens to have the support files from your supplier? I'm talking about the MTCE image (ZH_V2.75e_1) and the ROM image. It seems that I have the same type of HU and I couldn't find the newest factory images. Thanks!
[MTCD Software Development] iMattmax:
I installed this custom rom, but now I have a problem. How can I change or set the sound from the navi app louder, so that I can hear what this app would tell me. The radio has the normal loudness, but it seems that the navi is quiter.
[MTCD Software Development] typos1:
Same as in any other ROM - in settings, plus whatever nav app youre using (you dont say) may also have some sound settings too.
[MTCD Software Development] meazz1:
Go to

Factory settings --->> Voice---> system voice

and raise the voice to high ,17 18 etc.

and

Factory settings --->> Voice ---> Radio voice to tad bit lower

play with these settings and GPS voice to get the right output..

This worked for me for iGO, Sygic and CoPilot.
[MTCD Software Development] iMattmax:
I didn't find an answer to that question.

So is it possible?

Does it work with a dab+ adapter at the same way?

Don't use DAB here in the US, so not sure.

It doesn't complete the restart procedure. I get a black screen. Can u give me a solution forbmy problem ?

Ps : I found the problem. I had a faulty microsd. The headunit didn't boot with it in the gps slot ? I installed 2.3 and it works great. Thank you ☺

updata fail!

Hi, I would like to update my car radio to a new version of MCU and firmware but I can not, I always get an error:

Installation mcucfg start.

Installation mcucfg aborted.

I state that I am not an expert so it is possible that he is making a basic mistake; I have downloaded the update files from xda-developers from various discussions including this one, but the result is still the same. The update files load them on an SD card that I insert in the GPS slot, as per instructions, and then from the "recovery" I do "updata system / mcu image from sdcard and clear all".

The ROM you inserted in the previous answer (MTCB / C / D Mega Site for ROM / MCUs + URL) has the same date as in my car stereo (03 / 07/2017), which should be the official ROM. Do you have something more updated even if not official?

I want just some basic info.

I have a Head Unit for my Kia Rio 2012. It is a Rk3188 PX3 running Android 7.1.2

The current rom build is px3-userdebug 7.1.2 NHG47L eng.hct.20180409.162338 test-keys

And the MCU is MTCE_KSP_V2.81e_1

Both rom and mcu are updated by me since the factory ones where 20170904 and v2.77 respectively.

I just want to know what is this HCT code?

I've found new rom updates but they say HCT2 [

hct2_px3_7.1(20181012)

]. Are they compatible with my system?
