Replacing Audi Concert Head unit

[rb15]

Hi guys,

I have a 2015 Audi A4 Black edition with B&O sound system (the main reason for buying this model) We have connectivity issues with our phones and are becoming very frustrated with it and im considering pulling out the headunit and AMI connections in favour of a new Apple Carplay headunit.

My questions are as follows:

1) What happens to the screen in the dash, will this still function?
2) How does it effect the on-screen functions such as heating and parking system display? Will it still work?
3) Can we get the screen in the dash to do more if the headunit is replaced
