The update link is bad, it is https://www.carjoying.com/Joying-blog/41.html

FYI, the April 28th "UI Update" brings the ROM version up to 18042016.19:43:10 and from what I can tell there is no newer DMCU update newer than the one posted March 7th.

http://forum.carjoying.com/thread-16-post-278.html#pid278
[MTCD Software Development] Redline10000:
Don't do this update. If you minimize the radio app it quits and the radio widget does not work. Also the app for steering wheel control is missing .
[MTCD Software Development] sterod:
This is not completely correct. If you hit BACK the radio app closes, if you hit HOME it minimizes and runs in the background, this behaviour is unchanged from the March 28th build. The radio widget does not work for me either, that is true. The app for steering wheel control is not missing on mine. It is called "Wheel Key Study" and if you cant find it in the app drawer, just go to the Android settings screen and its there as well near the other driving menus.
[MTCD Software Development] Redline10000:
Ah I managed to fix the radio issue. It was a problem with my radio key mappings. However I still can't find "wheel key study". I might need to reflash.

[MTCD Software Development] hadeone:
Does the wheel key app do anything for you guys?

[MENTION=3590033]Malaysk[/MENTION] does the model number or the car the unit is made for matter when installing new Roms or firmware? For example will the firmware for a erisin generic double din unit work for the erisin bmw e46 es 3062 unit?
[MTCD Software Development] elhamy:
Do I need to rename the files to dupdate.img and dmcu.img ?
[MTCD Software Development] sterod:
No they will be detected properly as is. What I did notice however is that if you have both files in the same directory when you check for updates it will always only pick up the MCU file first. So what I had to do was move the MCU image out of the directory after it was updated so that it would see the ROM dupdate image and offer to upgrade that.
[MTCD Software Development] vwgti18:
No my wheel keys work on stock app only. Are you using a canbus box? I read you on VW and BMW the wheel buttons can not be remapped...someone correct me if I am wrong.
[MTCD Software Development] elhamy:
Thanks for your reply , let me confirm that I understood correctly, first time to update these devices

I will keep the files names update.img and mcu.img

And will keep mcu.img in the root directory to be updated first then I replace it with update.img to be updated after

Please correct if I'm wrong, thanks again
[MTCD Software Development] sterod:
I think you meant keep the filenames dmcu.img and dupdate.img

I typically do the dmcu.img first then when that is done, I move the dmcu.img file out of the root folder and place the dupdate.img inside.

I don't know if the order of flashing is relevant, but this is how I've done it and have not had an issue.

[MTCD Software Development] :
I have updated to MTCD_KGL_V1.65_1 but now I do not receive as many radio stations as I did before with old MCU version.

Can somebody provide the image for MTCD_KGL_V1.40_1?
[MTCD Software Development] masri1987:
I just received a 07\06\2016 ROM from Xtrons... for 5.1.1 mtcd if anyone is interested.

[MTCD Software Development] xchim_24:
Big thanks.
[MTCD Software Development] warata:
Anyone have Joying MCU firmware newer than MTCB-JY-V2.73?
[MTCD Software Development] masri1987:
not sure if it matters btw but my unit is a GS...
[MTCD Software Development] xchim_24:
It matters quite a lot, but I had picked the MCU from the file name.

The upgrade doesn't seem to have a mcu.img file, so maybe it's just a system upgrade.

Out of interest, what model xtrons do you have, and what is the MCU version in the about screen?

Also - how did you get this ROM, did you email someone asking for upgrades?
[MTCD Software Development] masri1987:
mine is the GS_1.61-1 i believe. i have that file too, i originally had 1.49-1

the file i shared w\u is just the new ROM

I have this

http://xtrons.com/pf75m211a-7-andro...irroring-function-obd2-for-mercedes-benz.html

I got the ROM and MCU from xtrons directly, support via their fb page and their forums

But it took me a lot of work, their customer service sucks
[MTCD Software Development] xchim_24:
Agree, if you've found the source for updates, don't lose their details
[MTCD Software Development] masri1987:
oh i don't plan on it, i think the key is consistency, and finding different ways to relay my message or needs to them.
[MTCD Software Development] :
Yes, it is set to my region.

Anyway I got from the producer the MTCD_KGL_1.40_1 and now the problem is solved.

Spotify steering wheel keys bindings

Hi Guys,

I developed the application for controlling Spotify by steering wheel keys.

Source code and apk file:

hxxps://github.com/f1xpl/SpotifyKeys (change xx to tt - due to xda restrictions I cannot post the links yet)

Application has been tested on MTCD GS 1.61 (Android 5.1) in BMW E38. As far as I know, BMW E38 does not use CanBus to send steering wheel keys commands, but I analyzed the built-in CDPlayer source code and it should not be a problem. Anyway - feedback will be really appreciated.

In a nutshell:

1. Install apk file available on github,

2. Open the application and learn it key codes:

2.1. Press "Learn < PREV > key code" button then press steering wheel key that you want to bind to switch to the previous track

2.2. Press "Learn < NEXT > key code" button then press steering wheel key that you want to bind to switch to the next track

2.3. Timeout for steering wheel key press is set to 5 seconds.

3. "Switch track when paused" option is used when you pause Spotify playback. Originally, when playback is paused and you press previous or next key, Spotify will resume playback. It is useful when you want to use e.g. CD Player but paused Spotify is running in the background.

3.1. When option is ON, after press NEXT or PREV, track will be changed and playback is resumed

3.2. When option is OFF, after press NEXT or PREV, do nothing.

Application has functionality of autostart (Android should run it in the background automatically after bootup) - so you do not need to make any additional actions except learning the keys at the very beggining :).

If you will have any problems with application setup, I can try to make an video tutorial.

Please give me a feedback if it works for you. Source code is open - fill free to contribute.

Best regards!
[MTCD Software Development] xchim_24:
Did the upgrade - xtrons PF75HGTA with GS 1.61 MCU, first time I've upgraded this unit, only had it a week.. and it's in the wifes car AND the car has a questionable battery.

Impressions - easy, although be aware that the first boot will sit on the car logo for quite a long time and you will have to reinstall and reconfigure all apps.

Had to re-learn a couple of buttons on the steering wheel, re-load gps mapping etc, all up it took the best part of an hour.

Didn't have time to test whether it fixed any of the problems I'd found - folder listing in mtkmusic etc.
[MTCD Software Development] masri1987:
so the file I gave you updated your MCU too? orw as it 1.61 before?

I upgraded mine within 3 days lol, OCD
[MTCD Software Development] xchim_24:
MCU was already 1.61, didn't touch it.
[MTCD Software Development] Samoawbc:
Thank you! Great work!

It works perfect on the stock Rom. My steering wheels Keys are connected to swc_key_1 on the Radio, so I can't test if can bus Keys will work to. I think you should start a seperate Thread, many people are looking for it and in this thread it might get lost.
[MTCD Software Development] f1x:
Thank you for the feedback :). Right now I am working on new version to support more keys for next and previous behavior (e.g. device's hard keys). Also I plan to support Google Play Music in future release. I will keep you in touch.
[MTCD Software Development] Samoawbc:
Great! On my unit, a kgl for a Ford Focus mk3 the Steeringwheel Keys and also the Buttons of the Unit it self works with your App.

Start a seperate Thread, the App is worth!
[MTCD Software Development] Dec64:
Really nice app f1x, works perfectly and nicely smooth. Definitely as said start your own thread for it.

Improvements if possible? Add to the "mode" rotation of apps, or better yet option to replace the MTCmusic with Spotify or our choice? Able to set a button to launch spotify from stearing wheel or hardware button?
[MTCD Software Development] f1x:
Thanks for the feedback :).

Right now I am not able to start a new thread due to forum restrictions (anti spam). Maybe some moderator will be able to separate discussion from this thread. Then we could create something like "Wish list" or "TODO" and add new features.

Right now I am focused on binding more than one key to PREV or NEXT action. When it will be finished (I think still today), then I could start to work on spotify "shortcut" and other stuff.

btw. It would be nice if someone could help me to request new thread :D.

New version of SpotifyKeys

Hi Guys,

I released new version of SpotifyKeys. Now you are able to bind multiple key codes to PREV or NEXT action. Binding can be removed by a long press.

Check it out:

github.com/f1xpl/SpotifyKeys

Waiting for a feedback.

Best regards!
[MTCD Software Development] Dec64:
Just tried version 1.3 and it does not work with prev/next anymore? Updated to 1.4, still prev/next do not work anymore but launch Spotify bind works perfectly
[MTCD Software Development] f1x:
Hello,

Thanks for the message. As far as I remember, in version 1.3 I changed shared preferences prefix for stored key codes. It can cause problem with previously stored key codes. I will make short note about it. Try to remove all learnt keys and perform learn procedures once again or uninstall and install the application.

Before installing of new version I recommend to uninstall previous one, just in case. Please let me know if this fixed your problem. I will try to support you as much as possible.

[MTCD Software Development] Dec64:
I tried uninstalling the app via the normal way and it still does not work. Is there a saved file I could delete or something in the system folder?
[MTCD Software Development] f1x:
You can try to wipe application data and cache. It is using shared preferences built-in in android.

Have you bound different key codes for launch/next/prev/toggle play? Key Code learning procedure has been succeed (application caught key press)?Also please note that switching prev/next when playback is paused is no longer available. I removed this functionality in order to support Google Play Music in future releases.

Edit:

Also one clue can be "Private session" feature in Spotify. If you enabled it - please disable and check. It should be somewhere in Spotify settings.

I just received a HotAudio unit.

It comes with specific ipod port but no wire has been delivered. Additionally hotaudio told me that iPod was not available for this unit.

On the settings for the unit (mcu) iPod appears as off.

Can I switch on or it could be something hardware related that no specific iPod hardware is included?

What version of iPod/iphone can be read?

Where can I get the apk for iPod/iphone ? (It is not installed)

Does anybody have the wire scheme to make my own cable?

Thank-you

Hello all,

I just got a new radio and I'm not sure which forum is the correct one community support for my unit.

Its an XTRONS branded unit that's specifically made for my Ford vehicle. I've attached a pic of the specs... hopefully someone can let me know. I have a few questions but I want to know that I'm in the right place 1st.

FW for MTCD-LM (Erisin)

Hello,

maybe someone has the latest firmware for a Erisin MTCD_LM Device:). Currently it is 1.56_1 installed.

Thank you very much

[MTCD Software Development] CadillacMike:
do these need to be installed in order? Or can you just jump to the newest one? For example:

Install V1.28_2, then install V1.49_2, then install V1.63_2?

Or can I just go right from V1.28_2 to V1.63_2?
[MTCD Software Development] doctorman:
you can jump between them
[MTCD Software Development] Dec64:
Sorry for the delay getting back to you. I remembered that I wiped my android unit and since installing spotify i had not chekced the setting to allow it to broadcast spotify song status. I checked the option and all was good again....untill like an hour later I came to use the car and the keys stopped working again? It seems hit and miss that it works at the moment. I'll try to experiment more tomorrow and update to your latest version.
[MTCD Software Development] zoppa:
Guys and gals, if you have specific questions about your unit, then please do not hesitate to open new threads in the MTCD forum.

This thread is about original ROMs, only. ;)

I have problem with OBDII on Malaysk ROM RK3188.

I have Torgue Pro and Dash command. Screenshot of OBD dongle is here:

Xtrons has posted updated firmware and mcu for many of their units on each product page.

What kind of trouble are you having with the bluetooth?
[MTCD Software Development] trap63:
Both with official fw on Xtrons site and Malaysk v5 when connecting a ODBII BT like OBD Link LX (suggested from Palmerperformance, DashCommand pro .apk http://www.palmerperformance.com/store/product_info.php?cPath=25&products_id=80) or generic BT (cheaper Chinese) UNABLE TO PAIRING and both Torque Pro and Dash command still loop under “Bluetooth request auth”. Tried to change key with “0000” and/or “1234” , problems still remain. ODB link LX official has a pairing key of 5 digits.

It’s ridiculous that an HW /HU provider didn’t verify BT compatibilities, universal interface standards and prefers to have on sale poor Chinese cheaper tool (i.g. Xtrons ELM BT, black) with cracked Pro apk.!

Sometimes Torque Pro (official not cracked) acquires paired but DashCommand Pro

not

, still opening BT ODBII port and waiting to see paried peripheral. None happens as no peripheral is detected and paired.

Only hope is that on this troubles [MENTION=3590033]Malaysk[/MENTION] will solve them in future (with too long serial id for network sensing of Tomtom GO)..

My idea of Chinese products still remain even the same along years: Junk…..

I'm pretty sure the one on the TD618AS page is wrong too.

It links to a file starting with GS containing two update.img and an MCU, but the unit calls itself MTCD_MLT_V1.60_1

Theoretically, if I needed to go back to factory on a Joying RK3188 then I'd flash twice. Once the dmcu.img and a second time with dupdate.img right?
[MTCD Software Development] zoppa:
Right, but MCU image, technically, only if you changed it. But of course it is better if it matches the firmare image you flash regarding release date.

So you should be perfectly safe if you flash both out of one official firmware package.
