By the looks of it the middle photo, shows that you're able to fit it without cutting the din's surrounding and it'll still fit.
You can see how there's a much greater gap between the little storage beneath it and the A/c control. Whether as the other two, they cut the din's surrounding making it a complete 4 din slot.
Am I making sense?
Pretty much, you can cut the din's surrounding/facia or leave it.
