Macan S and Carplay

[Razorman]

Hi, just bought a 2021 Macan S. It has Apple CarPlay working, but when using Google Maps the map only occupies the right 2/3rds of the screen. Anyone any idea if it can be made to cover the whole screen and if so how?

YouTube and everywhere else suggests it's a third party software install to do this.
