USB Type-C® Applications in Automobiles

Supports infotainment systems: connecting smartphones to IVI, making and receiving calls, listening to music, watching movies, synchronizing apps, activating voice assistants, and quick charging.

USB Type-C® Issues

USB Type-C® allows drivers to multitask while driving. It does so by enabling the transmission of audio-video data, and power delivery, all combined into a single interface. There are some common issues and frustrations with the USB Type-C® interface, however. The following scenarios describe situations where USB Type-C® fails to function normally, which could distract drivers.

  • Quick charging: overheats while charging devices
  • Reading information from devices: fail to synchronize data, or fail to connect
  • Using apps/software: the IVI fails to connect with your smartphone
