The Volvo system is much easier to use than some makers but needs study. I was stuck as all the new cars are now complicating the controls. Some makers have switches low down with tiny writing that needs reading glasses for me ! BMW having the worst controls and switches. The only controls i need are the radio station channels on the main screen on the move. All others can be set before a journey. Heater is controlled by voice.
Strange things are going into cars now with not even an oil dipstick. The car has to be running to check itself.
