Skoda Superb iV SE L - Amundsen Question

Hi

I'm new to this forum, hoping I can get some help with a couple of issues I've got. I'm driving a Superb iV SE L which I've only just had delivered new from the dealership a few weeks ago.

I'm finding the infotainment system quite frustrating:

1 - Navigation settings - Define preferred POI categories
In the settings I don't have any POIs selected (set favourite categories are all set to off) yet the map is absolutely littered with them. I don't want any POI displayed, is there any way of removing all the POIs from the navigation screen map ?

2 - Radio / Media volume

Is there a memory setting anywhere so the infotainment system remembers what the volume was when you last exited and locked the vehicle. Quite a lot of the time I drive around with the volume on the radio/media muted, I'll leave the vehicle and lock it yet when I get back in again the volume on the radio/media is back on when I'm expecting the vehicle to remember it was muted when I last used it. It's really annoying having to mute the volume each time I get in and start the vehicle.
In the volume settings menu there is a Maximum Switch on Volume, the lowest it will go is 3.

Thanks
