According to Harman, the next generation of sat-nav software will be more user-friendly and use a head-up display (HUD). The conventional screen will be replaced by technology known as 'augmented reality', which projects a computerised image on to the base of the car windscreen directly in front of the driver, and which can react in real time to the road outside. To find out how, Matthew Beecham talked with Harman's President Infotainment Sachin Lawande, Executive Vice President and President, Infotainment Division.
