For a long time I have wondered how the teams that design car stereos can fail so miserably at making car stereos easy to use. The function of a car stereo is not complicated, and there are few tasks that need to be considered in the design of a car stereo interface. Approximately in order of importance these tasks are;
- lower the volume
- kill the sound
- raise the volume
- select the source (e.g. FM, AM, CD, Auxiliary)
- skip tracks
- change the frequency
