Question on the visual appearance of the Navi System

:
Mazda CX-9 Grand Tour
Just purchased a 2018 CX-9 Grand tour. Question.. the navi system background is black or dark gray. use to Garmin being colored. The parks and rivers have green and blue but everything else is black.. any way to change it?
 
Its probably in night mode. You can either turn your headlights off, or if you want the screen bright even when the headlights are on, twist the little knob next to the speedometer.
