Provide access to Plex streaming audio and video, similar to Slacker (for audio) and similar Netflix (for video while parked).
Plex allows the owner to stream TV or videos and listen to music using your home computer/server. Plex allows the owner to stream any owned videos, music & TV via streaming. It also enables the owner to watch live TV and record TV on your home computer/server to be streamed later just like a DVR.
With Plex, when I’m charging, I could catch up on the latest Yellowstone or whatever it is you choose to record from live TV or watch a movie stored on your computer from home or via the many free Plex movies and TV series.
