Akirby;
OK, so this afternoon when I had the car out in the bright sun, on Auto and covered the sensor on top of the dash the NAV went into a very dark (black? Map). That is my recollection and is what I would call night mode (My F-350 goes into this mode at night) This evening I tested it. On Auto the best I could get the NAV screen to was a darker green, same as when I pulled into the garage during the day. I know it was in night mode because all the other screens Climate, Audio etc were in the dark mode versus the daytime light blue mode. Why it acts differently during the day with the sensor covered and at night in the pitch black I cannot understand. Another point is when I did go into the garage and the NAV went to darker green and I covered the sensor there was NO change in the NAV screen as there was when out in the sunlight.
Now that I have some data points I will try it again tomorrow in the sunlight. Any chance you can try some of these things if you are similarly equipped.
Does your NAV ever go into a really dark map mode when driving at night?
Thanks
