I looked into many different interface examples, ranging from the most simple icon based layouts to the more complex multi-level set-ups. Some examples of these can be seen below. The main thing I learned from looking into interfaces is that the more functionality you have, the more difficulty the user has using it.
From looking into interface design and how the user interacts with them I came to the conclusion that our radio would have a simple icon based interface. from our previous research into radio stations we knew we wanted six displayed in total. this allowed for a simple interface without any difficulties due to the screen size only being 3.5″ across. The image below is of the finished interface (displayed on a Computer screen) that myself and a good friend Petr Chutny developed. I personally have limited web development skills and so I called on a friend that I have worked with in the past. Using his experienced skills and knowledge he was able to develop this interface form me without any trouble. The interface is now hard-wired into the Musicbox server (Raspberry Pi 2) so that all external interfaces will display our new interface.
