Scania Nextgen Steering Wheel Removal

Hi All,
Has anyone taken the airbag out of the steering wheel on a new Scania?
The radio buttons are not working which is no big deal until you try to get the centre out.
I was told you have to cut an opening in the side which i have done but i can not find any bolt in there.
Was so easy on the old model i dont know why they have to make things so hard.

Any direction would be great.
Thanks

Old thread bump here but did you get sorted with this? I am driving a Scania next gen that has a Premium Radio but the steering wheel has blank radio controls on the left. I wonder is it a plug and play job to retrofit if I buy new buttons?
