Now, the button to switch traffic on/off be refreshed properly ...

Also, I have reread all the thread, but not be able to find how to add the "auto" tick option, there is only the 2 original options "day" & "night" tick options.

If someone have the modification, feel free to put it here ...

So I found out this small UI improvement:

In assistanceModeSettingsPage.qml, line 207 (inside the block "onBeforeShow:"), you can add the following line:

buttonModel.updateTraffic();

This will show the label "Hide traffic" and the corresponding icon if traffic has been activated.

uncomment the lines between 38 - 47

models\MapSettingsModel.qml

uncomment the lines between 88 - 91 and 129 - 163

views\assistancePage.qml

uncomment the lines between 100 - 105

sections of code that should have the /*, */ syntax removed.

The drive-qml approximation for the declination is legit, it is equation 3 from http://solardat.uoregon.edu/SolarRadiationBasics.html

What seems to be missing is probably a better approximation of the sun transit, i.e. the true sun noon.

Otherwise, just some signs were apparently wrong in the sunrise/sunset calculation, with that fixed, it works well enough for me.
