Are people not thinking of the driver profile which is standard??
I think that is what MH thinks it is on his Dad's car. But if this is the case why does it include options for the ACC?
I see some possibilities:
1. No ACC/DCC as it wasn't spec'd. Menu still exists but does nothing. This seems least likely to me.
2. ACC/DCC mistakenly fitted to this car.
3. It refers to something else... cruise control maybe? Does cruise control even have "sport" or "eco" mode? Why would it?
