The Connected VehicleInfotainment + Communication + Security

• Consumer electronics trends are dictating features in the car

• Always connected, applications driven, advanced graphics

• Infotainment systems becoming battleground for Auto differentiation

• As more connected systems get introduced into the vehicle, theneed for security is critical− Increasing external communication features

(Bluetooth, TPMS, Ethernet, Wi-Fi, etc).

− Future interface for vehicle-to-vehicle and vehicle-to-infrastructure.
