Update Navigationssystem of a Skoda Octavia

Today I tried to update my Navigation System of my Skoda Octavia and had some problems with the update. But at the end I was able so solve all problems and I share my experience here.

First you need to download the new software and this can be done on the following page:
updateportal.skoda-auto.com

The update had a size of 22GB, thats why I would recommend a 32GB SD-Card.
The most important part is, that the card needs to be specially formatted, that the update can work. Otherwise you always get an error message, that the card could not be read.

On my Mac I opened the disk utility and I’ve seen that the card was formated as GPT and not as MBR.

The Navigation System of my Skoda can only read cards with MBR format for the update. So you just start the disk utility, click on erase and choose MS-DOS (FAT) and as schema Master Boot Record.

At the End the volume needs to be formatted with a 4k Block-Size and this can be done with the following commands.

# read out correct disk id
diskutil list

# format disk
sudo newfs_msdos -F 32 -b 4096 <disk identifier>

# Example
sudo newfs_msdos -F 32 -b 4096 disk2s1
