Hi,
the teal color of the display and direction marker is hard to read against the background, especially light green wooded areas. And that's where I typically hike.
That said, I can see it fine with my reading glasses, but during hikes I don't want to put on glasses and the display is otherwise good enough so I can read it without glasses.
It would be nice to be able to change the color.
Also, POIs render above the teal text, which shouldn't be the case.
