Allow users to customise their nav screen so they can position and size the features they need.

Most importly, just because I want my audio player open with bigger track skip buttons and current track listing DO NOT DIM THE BRIGHTNESS OF THE MAP SCREEN! I’m still navigating, why make it dark and hard to see because I want to see what I’m listening to?!

your UI choices make impede some useful functionality. Let users choose what nav information they need, where on the screen it is and how large it is. Maybe I need a larger speedo and bigger audio buttons. Maybe the eta and miles remaining is too big and I would prefer my audio controls at the bottom of my screen?
