I am looking to buy a car with satellite-navigation fitted. I am confused by a lot of ads that mention a 'computer' or 'trip computer'. What do they mean by that? Does it mean that the car has satellite-navigation?
A trip computer in a car has various functions, but none of them will direct you to your destination.
They can log distance travelled, provide instantaneous fuel consumption, average fuel consumption and other variations around this theme.
You need to specifically look for adverts which mention satellite-navigation or sat-nav if you want to be told where to go.
