I went on a trip over the weekend and having the maps in the cluster is very nice. Yes all the info is still on the 12" screen but you have to look over and far down the dash to find what you want. With it in the cluster you just glance down and can see the turn info, arrival time and how any miles to go. What worked out nice too is I have my home screen to have the top part as carplay and waze is usually running by default so while I was using the uconnect maps waze was still telling me about hazards, cops, and speed traps.
Point of this post is to say if you are on the fence about dong the 23 bcm swap the little extra cost is worth it IMO
