Introduction

Mitsubishi MMCS NR-242 is a popular car navigation and multimedia system that helps drivers navigate unfamiliar roads, listen to music, and make hands-free phone calls while driving. One important aspect of maintaining this system is updating its firmware to ensure it runs smoothly and efficiently. Updating the firmware of your MMCS NR-242 can improve its performance, add new features, and fix any bugs or security issues. In this guide, we will walk you through the steps of updating the firmware of your Mitsubishi MMCS NR-242, so you can keep enjoying its many benefits on the road.

Note that the Bluetooth Hands Free Module Firmware is updated separately.

Tools

Step 1

You can find the Version Number of your MMCS printed on the top right corner of the unit.
In this case the Version Number is W-12.

Step 2

You can download the firmware files here: Version CR, CZ and CI.
Check if the Firmware Version works with your device.
MMCS E-11 and E-12 are analogues of W-13.
Download the Firmware for your device.
Press on SHOW ALL.
Download LOADING.KWI.

Doesn’t work webpage doesn’t come up

The link should just open in a new tab. I just checked, the website on the other end isn't broken. Maybe try opening the links through the right click menu.

Sebastian -

I can download now. Can I install this software to firmware E-11.

Thanks

Erol Emin -

Buenas tardes,

que diferencia hay entre Versión CR , CZ y CI .

Gracias

Luismi mg -

Different Versions are compatible with different devices. Which Software version you need will depend on the device version you have.

Sebastian -

muchas gracias!!!

Luismi mg -

my version is a W-15.

I need to install the next firmware: MMCS_W15_W17_firmware_rev_506372_ver_CR

Is correct?

thanks!!

Luismi mg -

Yes, that is correct. You need version CR.

Sebastian -

I have a question on this I have a N-11 which CZ is the firmware compatible with it I currently am on firmware AF is this all across regions or is this only for overseas vehicles I'm in the USA

MR214 -

Yes, it's compatible.

Step 3

The SD card needs to be formatted to FAT32. If it’s not already formatted to FAT32 and you don’t know how to do it, you can take a look at this guide.
Copy the LOADING.KWI file to the root directory of the SD Card.

Step 4

Press the OPEN-Button.
Press the Monitor OPEN-Button on the screen.

Step 5

Insert the SD Card into the USER-Slot.
Close the display by pressing the OPEN-Button again.

Step 6

The Unit will automatically detect the Firmware file and ask you if you want to update.
Press the Update-Button on the screen to proceed.
Do not turn off the car while the update is running!

The system recognises The update. I press The update button, but after it says : The sd card cannot be read. Doesn't make a lot of sense, since it recognises it, so why wouldn't it read it and update it? Any ideas?

Mitsubishi ASX 2013, Navi Version W-12

Besides restarting the car and trying again my only guess would be that maybe trying a different (16gb or less) SD card could help. It can be a bit picky with USB flash drives, it might also be picky with SD cards, though I never encountered that problem myself. What kind of card are you using?

If it still doesn't work you can also update from USB or CD. Just follow this guide starting at Step 11.

Hello from Greece, mine w-12 (2013 Mitsubishi ASX)says that I am trying to downgrade my firmware (my mmcs have 00107150) .Is that correct or I have to ignore it and proceed to installation. Thanks in advance.

George - 02/02/24

If it you already have a newer version installed, then you don't have to update your device.

Sebastian -

Thanks for your fast answer Sebastian, but its 2013 car model and i dont think that someone else update my firmware. I can read here that this Ver is 00104238 ******from 2019. thanks again

George -

Then you can just proceed. Maybe it's just a bug.

Sebastian -

Maybe I'll try it , I am not sure yet. What is your suggestion? If I try it I'll inform you. Thanks.

George -

Hello. I try different sd cards ,many ways to format fat32 and the procedure stops after Step 5. Doesn't recognize the "Loading.KWI" and doesn't start the update 😞😞😞

@georgianannou What kind of SD card are you using? The car only accepts SD or SDHC cards, meaning that the maximum capacity it recognises is 32gb, though it seems to work better with lower capacity cards, such as 4gb cards.

Sebastian -

I have tested 4-5 sd cards from 256 mb :-O to 16 gb , SD and SDHC .

But i remember that some weeks ago , works and i didn't proceed because i thought that was downgrade, so i update only the map to 2023A.

I dont give up, ill try again and ill inform you

Thanks again for your time .

George -

@geoaek The map data card already includes the newest firmware, so you don't need to run a seperate update.

Sebastian -

oh ok , thats good news , thanks Sebastian , you are amazing !

George -

Hi , something happened while updating and it froze, had no choice but to switch system off and now it has bricked the software,
Doesnt load into the software. Unit is still active, reverse camera comes on , and panel opens. Any suggestions on recovery would be appreciated. I tried the disconnect the battery over night trick with no luck. its a W-12 in Australia

I don't know, I never came across something like that. Maybe have a dealership take a look at it.

Sebastian -

Thanks @sedorr , maybe any suggestions on how to cold reset or boot off the Sd Card ? Should I have the LOADING.KWI in the root of the SD in the User or Map slot ?

Barry -

You can install firmware on the device in four ways: using a CD, a USB drive, a User SD card, or a Map SD card. Map SD cards automatically install the firmware during boot if a change is detected, although yours might be corrupted after attempting an update. Try removing the map card, restarting the unit, and then reinserting the map card while it's on. Alternatively, you could create a new European map card and insert that. For the User SD and USB methods, place the loading.kwi file in the root directory and connect it to the car. Note that you may need to confirm a message for this to work. If you can access the service menu, you can also force an update by long-pressing the "Navi (Application)" segment of the "Versions Indication" menu.

Sebastian -

Other problem is I now also have a CD that was in the unit stuck as I cant access the eject ...

Barry -

Habe die SD-Karte in den Kartenslot (rechts) eingeführt und folgende Meldung erhalten:

Navi-Programm gefunden in der Benutzer-SD Karte

Aktuelle Version 00104255

Gefundene Version 00104238

Programm Aktualisieren?

Heisst das nun, dass mein bereits vorhandenes Programm neuer oder älter ist?

Stephan -

Es kann sein dass du eine leicht neuere Software Version hast. Ich würde das Update in deinem Fall nicht machen.

Sebastian - 23/06/24

Step 7

After the update is finished, remove the SD Card by repeating Step 4 and 5.

Conclusion

Drive safe!

Un saludo Sebastián, José María de Cádiz, quiero actualizar los mapas de mi Mitsubishi Outlander 2017, mi equipo W-15, al entrar al enlace que pones como hacerlo, me sale que está desconectado temporalmente , otro enlace para poder descargar mapas y archivos del Sistema, para actualizarlo?...gracias

Jose Maria CHG -

Hola José María, lamentablemente el archivo en Internet Archive en mantenimiento durante los próximos días debido a una reciente violación de datos. Los archivos que buscas también están disponibles en una página rusa llamada MMC Manuals, pero te recomendaría esperar hasta que el Internet Archive línea vuelva a estar disponible para una descarga más segura.

Sebastian -

Do you know if this version (W12 10.42.38) is the latest versions? I have 10.71.50 and it asks me if I want to downgrade if I try to install this version. Is that correct?
