I'm not sure I can share it. This content come from LuckyLuke and he owns a shop so I imagine he prefers to keep that for him. But he shares if you ask.
So I've made a try yesterday after copying datas on a sd card with BalenaEtcher but it doesn't work.
I'm finishing the copy with dd command on Linux.
I hope it will work

"dd" can save your bacon, or burn it to a crisp if you get something wrong. Glad to hear it was the former.So the command dd on a linux operatig system did the trick!
My car is now repaired !!!
Thanks again to everybody.
Ahah Right! Never mix /dev/sdb with another one ^^
dd = destroy disk
Here is the corrupted data, I've downloaded them with ddrescue from the original sdcard.
I'm still copying it on a new sdcard so I cannot tell if it's working or not...
Good Luck

Hi all,
Since a few weeks, sometimes my mcu shows that the navigation data are not available.
everything else works: I see where I am, I see traffic data, spotify works.
I have to reboot if I want to use the navigation system.
After a reboot the navigation system works fine for a few days
Can it be a faulty sd card?

Trying my way around in Linux to get this script to run on a Windows based linux called Kali. Never once done something in terminal in Linux and very confusing but i came thus far that i can now go around in my C drive etc and found the .sh file that i downloaded from pastebin but to send the run command i have to determine the path to my sdcard but cant find my sdcard in terminal. I see the sdcard in Windows and its formatted in FAT32 and ready to go but cant find it anywhere in linux terminal.
Been at this for several hours and starting to get depressed....
You guys that done this, how did you find your path to sdcard ?
googleing for hours now and trying these kind of mount commands but it dont work...

Yes, it could definitely be your SD Card! It did the same on my car at the beginning and after a month the navigation stopped working. Except display, position, trafic, radio, spotify... Just the navigation.
If you use a virtual machine don't forget to connect your sdcard to the guest system (the linux OS) if not so you can see it with a sudo fdisk -l command.
Normally, the path is something like /dev/sdb2
You can check in my message down there, how it has to be displayed. It's a Debian virtual machine but you expect the same result anyway.
Hello everybody,
I've got the same issue since 2 months. At the beginning it just disappeared with a reset but not anymore.
I've asked Tesla they charge me 155€ to do it. Not so much but I need to drive 200kms away from home.
As I have a 16Gb Sandisk Ultra SDCard, I'm trying to save the data of the original one. Which was a bit oily.
The content are broken.

dd is incredibly long

Does anyone has the .sh script suggested by LuckyLuke and/or the image of the sdcard for europe?
Thanks a lot
And sorry for my bad English...

I find your English written better than many native writers.
In my special case, I have replaced it with a Sandisk Ultra 16Go SdCard that I have copied with some known good datas.
I've copied datas on it through DD command on a Linux OS.
It worked straight from a reboot.
Datas comes from LuckyLuke I don't share it here because I'm not sure that I can. He owns a shop to repair sell part for electric cars so may be it's a part of his job. And he gives it to me for free. I imagine you can ask him too...
I've read some people inserting the fresh new SDCard right into the MCU and after a reboot the MCU has downloaded nav datas.
I haven't tried that.
And I have shared here (Post #86) my saved but normally corrupted datas. I you try them and it works please tell me
Hi Guys, I have PMed Luke about my situation.
But he haven’t replied.
I had a message saying incorrect maps was loaded, not it’s just say no navigation data loaded .
Since my car is an import from Hong Kong, Tesla UK won’t reformat or replace it or even send over map data OVA.
Please anyone can help me out here?

Tesla won´t take it in and change sdcard even if you pay for it ?
If not then i would try to buy a new sdcard and do the script that Luckyluke linked to create the correct partitions on it so you then can transfer the the european maps on to it and put it back in to the MCU. No idea if the car somehow just accepts maps of Asia since your comment about "incorrect maps was loaded" but its worth shot. Im no expert but thats what i would have done.
I also would like to give a big thanks to Luckyluke for providing the info, script and videos to make a new sdcard.
Installed it today and it took like 15 minutes after i powered up the MCU for it to start downloading maps. Everything works great now !
Its people like Luckyluke that will help the owners of Teslas to drive their cars to a million miles !
Thanks again

well i tried a more simple approach mine had not failed completely so i removed the sd card and bought a sandisc ultra microSDXC UHS-1 32gb card as i know absolutley nothing about linux
i downloaded a simple windows utility WIN32 Disk Imager 1.0 made a copy saved it to my pc desktop and simply wrote the imag back to the new sd card with out formatting and it seems to work fine and is 5x faster i hope it helps someone in the future.

Hi LuckyLuke,
As a new member I can't sent PM's but I hope you can help me
I need the microSD card image for EUROPE as partitioning the new card didn't trigger the nav maps download.
My original microSD card was unreadable.
I need this urgently as I have a long trip planned ahead and Tesla cannot book me in time.
Please note that I can pay for this service

i have the image file of the one that worked for me i could send it via mega or send me an sd card and i will copy it for you.
Hi all,
Can any of you provide me with the EUROPE image?
As with most of you here I was also hit by this microSD card problem (the latest map update came for me around 1 month after eMMC update by Tesla, of course they did not change the microSD card...)
Long story short, I already replaced the sd card myself with a newly formatted one using the script, but I only got a message stating "congratulations, you have the latest map version" or something like that despite having just inserted a fresh formatted card. Update option never came after one week now, wifi or not.
Since I am unable to read the original card (was not working for quite some time despite reset/reboot) I would really appreciate the help here. This involves taking it all apart again, hopefully I do not break anything, the first time went quite smooth actually.
