EV Play Max for Chevy, GM & Cadillac EVs

(I put it in this EVP Play LT for GM EVs Bug Reporting because it's the only section about your GM products. I'm sorry this message is not about a bug.)

I've been using the EV Play LT for a while now, and I love it. It actually makes me angry that Chevy is saying they are rolling out video apps and things like that, but I can't find a way to get that update, and I received the first EV Blazer that the dealership had delivered on site when it came out.

Anyway, I'm excited to get my hands on the EV Play Max. I have a few questions about the device. 

• "A Portable Mini Computer For Your Home Or Office
  EV Play Max isn’t just for your car — disconnect it, take it inside, and plug it into your TV. It then becomes a full-featured home media system by installing Plex, Jellyfin, or Kodi. Run Home Assistant for whole-home smart device control, or install and run local AI LLMs using its built-in 6 TOPS NPU. When you’re ready to hit the road, unplug it, drop it back in the car, and it picks up right where it left off. One device. Limitless possibilities."
  • I've been interested in setting up Home Assistant for a while now. I was going to get Home Assist Green, but it seems this could pull double duty. Can you direct me to resources where I can learn more about implementing it on the EV Play Max?
• "You can also mirror the device via its HDMI-out port, or wirelessly, to headrest monitors!"
  • Two questions about this
    • Can video be sent to headrest monitors while the vehicle is in motion?
    • Can you link a headrest monitor that would work with this and/or give the specs for what we would want to ensure the headrest monitors are compatible?
