Hi Robin, first of all thanks for the fantastic app,
I see that I'm not the only one that has a problem to see the instructions on the screen, I also can't see the arrow and other information when driven
I will make some suggestions that maybe can make a big difference for me and probably for the many requests concerning the visibility of the app on the screen.
My question is if it is also possible to add something like this in your app? Maybe there is also the possibility to split the screen, on one half the map and the other half the info in a high contrast.
Sygic HUD screen example:
My suggestion: 
I hope that you can do something in the future about this problem because you have a wonderful product!!
thx
