I was quite surprised the W205 had MBUX type voice commands
Voice commands:
"Set temperature to 20 degrees"
"Turn rear passenger light on"
"Turn display off"
Aren't in the manual.
I tried "open sunroof" and "open drivers window" but that didn't work, not sure if that works for MBUX cars.
But "turn on rear window demister" works but can't remember if that is the correct phrasing.
There are other documented voice commands in the manual
