Offer a single button to access the phone menu, rather than the two steps needed in v10.
Starting a phone call can be less focus-demanding, and therefore safer, if the phone icon was pleased in the main line, perhaps next to the music button. The seat heater buttons on the other hand aren’t needed on the main line as they are only used in some parts of the world, some of the time.
Implemented in V11. You can select which icons appear in the bottom function bar.
