I can't move more apps to iphone 7 and car play.
I have an iphone 7 and I just got a new Toyota RAV4 with car play. I have car play connected to my iPhone 7 and there are 5 apps on the car play screen in my RAV4. I want to add more apps but I can't. In my iPhone 7 screen for customize it shows the apps that are in the car play but I can't add anymore, no matter what I try I can't get more apps in the customize window, in addition the apps that are there I can't delete. Any ideas??
