If it is possible, it is just a suggestion in order to change the car screen system to something that you can do and it will be a very wonderful program.
First - themes for the program: colors, models of cars and their companies. We can control them within Apple CarPlay and Android Auto.
Secondly - The speedometer tab has a sporty shape and neat shapes that you can design and they are integrated with the themes that you will make with each car, company and model that has its own meter 💖💖
