I thought it would be useful to create this separate topic and collate information as now Infotainment Software Version 1969 is out in the wild I imagine user interest will increase. All credit to those who posted information in other threads - I hopefully have credited you all where necessary. Feel free to comment on your own experiences and observations.
Despite saying I was going to wait for this update to come OTA, based on the principle of “If it ain’t broken….” I bit the bullet and applied the 1969 update manually this morning (I'm a sucker for an update). All went very smoothly and took around 20 minutes. Seems an obvious point but to put your car in ignition mode, which you need to do to apply the update, just press the Start Stop button on its own, without depressing the Clutch / Brake which you would do if you were starting the engine I also switched off the climate control before proceeding although I imagine the Update process would disable its functioning anyway.
I followed a previous guide for version 1941 by @TheWanderer which was invaluable. I highly recommend watching the YouTube video in the instructions as you are updating as it is a useful reference of the stages your system is going through.
I have copied and pasted his guide below but it’s not my work, full credit to @TheWanderer for this:
Create a temporary folder on your PC or Tablet for example MIB3 UG.
Then find the zip file and then right click on it or press and hold on it, so the menu appears and it should offer you the opportunity to Extract here or elsewhere, tell it to extract the files to MIB3 UG folder and let it get on with it.
When it has finished, format a usb memory stick so it's completely empty, then go to the folder MIB3 UG open it and copy the 2 folders and other file directly onto the memory stick.
When it has finished copying the files to the memory stick it should look something like this... THERE MUST BE NO OTHER FILES THAN THIS.
Once your memory stick looks like this, remove it and take it to the car. Insert it into a USB port, press and hold the menu button for about 10 seconds and the update menu will appear.
At this point it's vital that you have a full or very well charged car battery or a battery charger attached so that the car doesn't shutdown halfway through the process. Ignition needs to be ON, the Engine needs to be OFF (NOT RUNNING)!
DO NOT START IT DURING THE PROCESS.
Here's a video that shows you what to do, albeit in German, you'll get the English version! If you watch it carefully you'll get the gist of what to do.
UNDER NO CIRCUMSTANCES MUST THE PROCESS BE STOPPED ONCE IT HAS STARTED OTHERWISE YOU'LL MORE THAN LIKELY NEED A NEW INFOTAINMENT SYSTEM.
Notes.
After it has finished updating the system, give it a couple of minutes to ensure that all is well and like it shows on video press resume an wait for about 90s or so and the system will restart just, like in the video.
DO NOT START THE CAR UNTIL THE SYSTEM HAS RESTARTED
After the update the built-in manual is unlikely to be available for about 48hrs, it does come back!
You will more than likely receive another OTA update, it's OK to accept it.
Ultimately if you are at all worried about doing it, take it to a VW Independent or Skoda dealer and ask them to do it for you
Once it has been updated, there should be no more random restarts or crashes on the infotainment system, the pop pop issue should be gone too..
