i just got a z2 about a week ago and when it gets night the nav screen is the day tan color and i can figure out how to change is to the night black color...ive tried to do it manually but all i get is the options of day or automatic..any suggestions???

automatic will change to night mode if the illumination wire is hooked up properly. check the connection screen to see if it is hooked up. or select auto mode and turn on your headlights
