Introduction
Keeping your car's navigation system up-to-date is essential for ensuring that you arrive at your destination quickly and efficiently. The Mitsubishi MMCS NR-242 is a popular car navigation system that is widely used by drivers around the world. If you own one of these systems, you may want to update its map data to stay current with the latest roads, highways, and points of interest. In this guide, we will provide you with step-by-step instructions on how to update the map data of your Mitsubishi MMCS NR-242, so you can stay on the right track no matter where you go. Whether you're planning a long road trip or just need directions to a new location, updating your MMCS NR-242 map data is a simple and important task that will help you make the most of your navigation system.
Note
Note that the new card will be paired to the head unit. It will not work in a different head unit and will no longer be readable by a computer after it was read and recognized by the unit for the first time. While it is possible to unpair the Map Card on MMCS versions W-11 and W-12, it is nearly impossible on all other versions without a special unlocking tool or erasing all data on the Card.

THANKS ,
for your support
yes I did step 5 and 6 but I was not on the physical media
it was my mistake
after that you had to do step 7 format in NFTS
on the other hand in NFTS format of the SD16GB card has less than 15,718,400,000
thanks I have to give it a try in the car
Ps, being French I made an error in the email received from support
I accidentally unsubscribed from sending emails
how can I reactivate it
after inserting the card it just pops up for a second that update and then it says error about the card and it's data. any idea how to fix this?
Continuing from step 12 onwards could help. If that doesn't work you can also try [lien de tutoriel non valide].
yes but the problem is exactly from step 12 forward, I can put the card in and star the actions etc. but on step 14 trying to finish the update it just gives error about the data and it will not continue, all I can do is change back the original SD (which has maps from 2014) and that will still work... so any idea what might be the cause?
