Mmi screen 7” to 8.2” change

[Sid2020]

Looking at possibility of changing my 7inch mini to the 8.2” mmi. Mainly due to fitting a reverse camera. The reverse camera display on the 8.2 screen is far  better then on the 7inch screen due to the way it displays the pdc sensor info at the same time. Is it possible to just swop between the 2 screens even though I have the mono chrome cluster. Away on training course at the moment but believe I have mib2 as I have CarPlay as standard but I may stand corrected. Any info or advice is welcomed
