Manufacturers have a critical role in creating a good experience of broadcast radio for the driver.

Working within their Human-Machine Interface (HMI), they must ensure radio content is displayed clearly, consistently, and safely. The interface must support fast recognition, familiar interaction patterns, and compliance with accessibility and legibility standards.

  • Each vehicle manufacturer uses their own HMI, so the guidelines enable designers to use best practices that work with any house style without losing legibility or usability
  • Broadcasters and manufacturers must both follow the guidelines to make sure the experience is consistent and works as expected
  • The UX should be designed for ease of use and align with how drivers already understand radio in vehicles, using familiar actions and icons
  • Clear guidance is provided on how to design, present, and update content to drivers on screens with dense information capabilities

Choose your starting point based on your needs:

Design Guidelines covers the first principles of visual design elements for a radio HMI. We know you might have limited flexibility here if radio needs to fit within your existing design system.

The remaining sections cover how to display and handle radio-specific information and behaviours. These are important for everyone, regardless of your design approach.
