how do i remove the radio surround on the dash?

[hookbeak]

Short version: battery replaced, radio reset, discovered i dont have the code, find out my radio needs a serial from the back of the radio to get hold of the code.

Can anyone tell me how to remove the surround from the radio here? Lots of YouTube videos for similar, but not this exact dashboard and I’m stumped.

Thanks for any help!
