A good-quality 7.0in infotainment screen comes as standard and is operated via a small, clickable touchpad and rotary dial between the front seats. The dial is the more usable choice, though - it is intuitive to use and gives more sensory feedback. There are also supplementary controls on the steering wheel. All models get Bluetooth and DAB radio, but unlike the BMW 3 Series, sat-nav is not standard across the range - it is only included with Sport and AMG Line trim, and even then it's a fairly basic Garmin system that’s not very slick. A much better navigation facility is available with those two trim choices as part of the extensive but pricey Premium Plus pack that also brings other goodies such as an 8.4in, high resolution screen and 13-speaker Burmester sound system.
