Mine are also set to my keys for to of the layouts. I'm not just talking radio stations, each of the at least 3 drivers, ( I don't know if there may be more, because I have two, and it sort of asks if I want to add another), can change total layout. One person can have only one screen, while another has split to two or three, by using keys or pusning user button. With the 12 you lose the heated seat and steering wheel buttons. The steering wheel gets way too hot for me, so I always turn off after a couple miles. It's much easier hitting a dedicated button, than searching screens to turn it off.
