Add wireless Apple CarPlay and Android Auto to your Discovery 4 while keeping everything the car already gives you: the factory touchscreen, the steering wheel controls, the factory microphone and your own sound system, whether that is the base setup, Harman Kardon Logic 7 or Meridian. CarPlay Direct is the official UK authorised Mr12Volt stockist. The Discovery 4, sold as the LR4 in some markets, takes one of two kits depending on which infotainment system your car left the factory with, and both are genuine MOST fibre optic interfaces built for that exact system.
