I have a 2018 SFS w/ updated f/w and Nav. When Nav switches over to night mode on the display the roads are almost impossible to see. I've adjusted the dash brightness to no avail. Is there any way to increase the contrast so roadways are more visable? Also, day mode uses the color gray to highlight your route vs some color that stands out like blue. It's not very visual compared to phone gps apps like Waze or Google.
