Firmware updates for the Hyundai i30

Recently I found out that my car (an Hyundai i30 Premium 1.0 T-GDI 2018 model) has an SD-card slot with the maps on there. I also found out that in the Hyundai media system there is a screen with the maps and firmware version. I’ve got atwo questions about the firmware?

1. Is it possible to download a firmware update somewhere (to install it on my car)?
2. Is it possible to see the changelog of the firmware somewhere? I would love to see what the updates fix/improve.

I searched for the firmware but could only find maps updates. And these updates weren’t even on the official Hyundai website. I haven’t found anything about firmware updates yet.

I am aware that a dealer can update the firmware, but I would like to try it out myself and I would love to know what is fixed/improved in newer versions.

The current firmware version that is displayed in the media system is: PD.EUR.0.5.222.170920.MICOM
