I have my '15 S550 set for miles (not kilometers), but have noticed that when I call for a list of similar POI's (e.g. fast food), the list comes up with distances in km only. I can find no setting that allows me to change this. Everything else displays in miles and I have reset it on the steering wheel to see if this helps - it doesn't. I searched the e-manual and can't find it there and have searched google. Anyone know if this is unfixable or if I am just missing a simple setting change?
