Car Radio Interface Enhancement

I am in need of a firmware expert who can modify my car radio software to enhance user experience. Specifically, the task will involve:
- Improving the user interface, with a focus on the layout and design.
- Adding graphical elements to make the interface more interactive and intuitive.

The ideal candidate should have experience in firmware development, especially related to car audio systems. Competency in UI/UX design principles, especially within automotive applications is also important. A keen understanding of how to work with graphical elements in firmware would be beneficial. The goal is to create a more engaging, visually-appealing interface for my car radio.
