Harman International Industries Inc. invested in a startup that makes projection displays that sit in front of car windshields, signalling a new area it plans to explore under the ownership of Samsung Electronics Co. The investment in Navdy Inc. is Harman’s first since agreeing to sell itself to Samsung for $8 billion last month. Harman will work with the startup to sell co-branded devices next year, said Doug Simpson, Navdy’s chief executive officer. Navdy’s hardware is placed above the steering wheel and projects information from the driver’s smartphone onto a transparent screen, so the driver can see updates at a glance. The heads-up display, which sells for $799, can deliver driving directions, text messages, song titles and alerts about incoming phone calls.
