Navigational (global Positioning System) Gps problems of the 2015 Honda Odyssey

We embarked on an 8806 mile, 22 day road trip through the south and southwest to the midwest with our new 2015 Honda Odyssey ex. Driving was done during daylight hours only with the headlights on and instrument cluster lights as high as they could be set. All windows are tinted. 21 of the days were bright and sunny. We could not see the instrument cluster display on bright days. Neither the speedometer or the tachometer were readable. My wife monitored our speed with a garmin gps. This cluster has white numerals and a pale grey background. This is a design flaw which makes operation unsafe on bright days.
