The screen colors on TrakteQ devices cannot be adjusted or changed.
However you can switch between 'Daytime' or 'Nighttime' color mode options. Switching between these options will give you either a 'light' or 'dark' background.
To adjust this option follow the steps below:
1. From the Map main menu, tap 'Menu'
2. Tap 'Settings'
3. Tap 'Map Settings'
4. Select from Day/Night Mode (This will allow you to select which mode you want)
Note: The setting labeled "Auto" will automatically change the color mode from Daytime to Nighttime according to Sunrise and Sunset information in the device.
