So a couple of updates:
First, I just had an over the air update and since then the dimmer scroll wheel now includes the nav screen brightness with the changes in brightness of the dashboard and other lighting as I turn the wheel—when in a certain mode. Let me explain.
All of the below is with the brightness settings set to “automatic” in the settings menu.
In the dark, with headlights set to automatic (And on)...works as described above which I will from now on refer to as normal since that is what we have all come to expect the operation of the dimmer wheel to include all screens and devices,
In the brightness of day, with headlights set to automatic (and off)...works as you would expect...all screens at full brightness and dimmer wheel does nothing.
But
with headlights set to automatic (and on) with a certain amount of light such as dawn getting brighter...the nav screen, dashboard (speedo...) and all other lighted buttons revert to “full brightness” setting and the dimmer wheel does nothing, even though the headlights are still on.
In the above circumstance changing from automatic headlights to running lights or manual headlights on will re-enable to dimmer switch to work as normal.
So
There must be some kind of sensor, independent of the sensor that turns on or off the headlights, there must be some kind of in-cabin light sensor that determines there is enough light to keep the dashboard at full brightness.
This
This is the thing that I have an issue with as I find it reverts the dashboard lights to full brightness too early as well as keeping them in full brightness too long I’m the evening.
