Creating 32 GB SD Map card with a PC (Mac variations available)
Best things take longer. Exciter in one of his seminal posts of 2017 described how he cloned the original card with CID onto a new card. That's in the PDF, take the right hand button to download else you get lost in other stuff on the link.
Wrote some lines on how I did it.

With the standard MIB2 maps due to pop the 16GB current card limit at some future date (Skoda warns you on their portal screen in German) and the fact that the last three standard satnav Skoda card releases have been on 32GB cards and releases are now zoned to fit on 16GB cards, although currently the all Europe release fits on the 16GB card - the day of reckoning where if you fancy driving across Europe with the standard system with all maps on your current card, updated, will end. If you are not travelling across Europe no worries although this does give you a back up card. Some technical skills required thou.
In April I bought a so called "gold card" was the Samsung Evo Plus Card off ebay UK sold as "
Samsung 32GB SDHC SD Memory Card - Korea Edition - CID Changeable SD". It came from Belgium or Holland. Mard30. Obviously available from anyone that sells that as such and you trust the seller.
Basically the 2016 or so Samsung Evo cards both SD and micro SD were configured in a way that the CID memory location could be re-written.
This was changed in latter models so best to buy only those sold as such.
There is a thread on the subject:

The author of the code that Exciter used in the post is
Richard Burton:

The library he posted up on Github
https://github.com/raburton/evoplus_cid
The Android one is compiled since he was working with a micro SD card. Ubunto you have to recompile yourself, easy enough. There is now a Youtube video that was done by someone else using Richard's Github post using Ubunto.
Prerequisites
1. A suitable
Samsung Evo Plus card sold for the purpose (32 or 64 GB, not the latest). I don't recommend working your way through a bunch of cards yourself but find a seller based on the spec above.
2.
Ubunto on a laptop or other hardware where the card reader is directly connected to the motherboard. USB based ones won't work. If a tower unit has an SD card reader next to USB ports it's likely the SD card reader goes in via the USB port of the motherboard. An SD reader connected via an IDE port will not work. PCI is the order of the day with the SD reader integrated onto the motherboard. Basically the Ubunto drivers must be able to read / write to the CID and those drivers as I understand it do with PCI but nothing else.
You can experiment on whether your hardware is up to it without buying a suitable card since if it's not up to it won't return the CID. I know this from an IDE SD card reader I put on an old XP PC I was given. It became my Ubunto test machine since I didn't want to mess up my laptop,
reality is that you don't have to install Ubunto on your equipment you install it on a pen / USB drive leaving the rest of the equipment in tact. You boot from the pen drive.
We take Exciters step 1
1.) Download an install Ubuntu on your USB drive. Choose „try ubuntu“ while you boot from USB.
OK we need to boot from a pen drive not copy it onto the system. He used a Mac, we'll use a PC laptop / notebook.
This is where we turn to a younger, helper:
The application is PendriveLinux.com
https://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/
So Phillip tells you
how to use that.
Worth noting if you have a mature PC laptop it's likely to be 32 bit and the 32 bit Ubunto isn't on the drop down list although it's got support for another 5 years.
You download it from here, taking the second link:
http://releases.ubuntu.com/16.04/
32-bit PC (i386) desktop image
Then using the latest release of the pen drive software
Universal-USB-Installer-1.9.9.0 (or later) you can pull in the 386 iso that is not on the list by selecting Ubuntu then pick up the saved iso rather than ones the software is offering.
We're doing it with this main flavour of Ubunto since the screen layout tallies with the
how to do the CID video below.
At the point where Philip stretches the bar at 5 minutes in, don't set it "as high as you possibly can" since the software won't fit on the pen drive. That piece of memory is your Ubunto environment area where your results will be stored so if you come back again you just pick up from where you got to. The drive becomes your virtual Ubunto detachable machine. I had a 64GB USB so set that bar at 50:50 giving myself 32 GB of work area. Plenty.
You next need to adjust your laptop so it finds the USB as the first bootable drive. Press F2 during boot up and make the appropriate adjustments. This varies by manufacturer. Some times you turn it "on" to boot from the USB and put the USB at the top of the list so it boots into Ubunto first. It will still see the PCs drives etc.
https://www.lifewire.com/change-the-boot-order-in-bios-2624528
or check the manual / do a Google etc. You can leave it configured like this after. You'd need it if you ever needed to use the Windows 10 recovery process where a boot USB is manufactured as part of installation.
OK once the bios is saved, reboot with USB in and it will boot into Ubunto. Now either press
'try Ubunto' or leave it to take this one after it times out from waiting for an answer.
Don't install !. You can install it but you are into dual boot and there is absolutely no reason to install it, you can do the task running it off the USB drive.
It boots into Ubunto off the USB stick. Dependent on whether you have Ethernet plugged into the hardware or using wireless, for wireless head up to the top right and click the wireless icon and supply the wi-fi key. Connected via Ethernet there is nothing else to be configured.
So we watch that video to the end.

This point we leave Exciter's instructions and refer to the video:
The screen is indeed Ubunto
.
You open the Firefox browser and pick off Richard's git code.
The sudo -s
is required again if you ever come back into this USB environment for more tinkering. Password isn't required since Ubunto isn't installed so a password is not setup.
Do the change directory and stop, you won't have git... git is here, do this:
https://www.digitalocean.com/community/tutorials/how-to-install-git-on-ubuntu-18-04-quickstart
These instructions work. So the default package updates, install git and return to video at git clone.
Motor onto 3:50, do the compile. It does compile with warnings... that isn't an issue.
Stop at 4:31. You can put your navigation card in
clipped to LOCK. Check !!!.
SD will pop up on the left.
Now the all important
find /sys -name cid -print
Now if after typing that in the jnt directory you don't see the code returned in the highlighted area at 5:00. You are out of luck Ubunto isn't reading you SD card reader to get the CID (probably your SD reader isn't connected directly to the motherboard).
If you have that code continue.
The
more after the cut and paste shows you the CID.
Open up the text editor and paste it there and save it.
Where the video gets
dangerous at
mount you swap the card out from the original and put in your target card... don't swap it out and it would attempt to write back the CID to your original card. Proceed on.
That's it. That's Exciter's 1-9 on the PDF with a bit of explanation on
how to do it on a PC laptop / netbook and test for whether you can do it with your hardware using
find /sys -name cid -print
returning a blank.
At this point if you haven't already got the navigation files on the target card, copy them on and you will naturally need your original overall.nds file on there as always.
Now free to drive across Europe when the standard maps for all of Europe when the 16GB file size is broken or just have a back up of your CID just in case the original card fails.
Note. Ubunto is closed down on the cog top right, shutdown. Pull out USB, equipment will boot back up as normal as long as you didn't try to install Ubunto to the the disk drive. It would ask you about disk partitioning if you went down that route by accident... (may be). The compiled software is retained on the USB and you saved the text note book file
.

Remember to keep the original card clipped to locked and obviously the contents copied out should disaster strike. Take care not to go onto the CID writing process with the original card still in. I would not waste time trying the writing process out on anything other than the card sold for the purpose. It's only for those original Samsung Evo Plus cards of the manufactured year in question (batch of them).
