The new Tesla Model Y comes with two USB-C ports, a 12v (12 amp) DC auto aux power outlet, and a USB port for Sentry Mode recording.

The Tesla manual says these ports are to:
- Connect and charge USB devices
- Play audio files
- Save videos when using Sentry Mode or Dash cam

Summary: As Tesla says, these charges are for charging any playing music, with no video or photo support, but no doubt could get added later. The MP3 player is quite responsive and works great.
