Neat and I feel like this could be easily learned by a driver. Minor feedback: the audio level selection seems to move on linear scale, but volume is a logarithmic scale. The perceived difference between 16db and 8db is the same as the perceived difference between 4db and 2db. If the audio is on a linear scale, then the sensitivity of the screen will be much more on one side than the other.

Nice! I knew I couldn't fool anyone with my wannabe professional -dB label there.
