On the menus to the left of the speedo under meter settings, there is an option to change the colour theme from blue to brown. I have tried to change this but it doesn't seem to make any difference. Does anyone know what changing this actually does?

 

It changes the color theme on the info-tainment system menus. Doesn't seem to have any affect on the meter displays.

 

Thanks for the explanation, I wasn't expecting that to happen so I didn't look there!
