I thought I had turned off all Advanced Driver Assistance Systems (ADAS) tools on my car but ever so often a voice says "Caution" What is it trying to tell me and how do I turn it off? UK spec car 2019 S550 (5.0)
Thanks Escosie, I will try to observe and see if that is a likely reason, I think you may be right! The locations it has happened in may well be speed camera locations. Anyone else concur?
Yes, that's what I suspect, too. There must be a setting in the navigation system. The stock navigation is TMC-compatible. You'll get traffic info and alerts if you're in a country where TMC is active. I remember seeing warnings when I was in Hungary or Austria, though I can't remember whether they were also audible. I believe they weren't, but that may be just because I keep the navi voice off all the time.
I would look at the Sync settings, in the navigation section. There should be an option there to turn the warnings off. If there isn't, you can at least turn off the navi voice; that should shut them up.
