Quick Access to Radio
It’s really important for drivers to have a simple, short journey to access their radio, regardless of where they are in the HMI.
Hardware Button
Section titled “Hardware Button”The simplest access is always the safest. Include a dedicated Radio button on the console that switches the HMI context directly to the radio screen - no menus, no extra taps.

Persistent on-screen soft key
Section titled “Persistent on-screen soft key”If it’s impossible to provide a physical button, include a clearly labelled Radio soft key that appears consistently across all screens. It should always lead directly to radio functionality.

If it’s impossible to provide top level access, make sure the path to Radio is clear and intuitive, and no more than two actions.
