I had these installed yesterday:

They are the same thing
@Husker4theSpurs put in.
They are amazing and if you can get over the price (about $1600 installed), they are worth every penny.
They're full Android tablets so I installed Disney+, Netflix, HBOMax, etc. through the Google Play Store and will run everything off the vehicle hotspot ($20/mo for unlimited data). Included IR headphones as well as a built-in FM modulator. They also have a DVD slot. Either screen can play its own thing, or you can mirror one to the other.
The real selling point, however, is the app that allows my wife to mirror the screens on her phone; that allows her to run everything from the front seat without any interaction from the little gremlins in the back seat...no more gymnastics to see what's happening on the screen and get everything started. Quality is, as far as I can tell, excellent.
And, of course, unlike the factory system, when I sell the vehicle and move to something else, these will come with me to the new one. Because they are android tablets, they update OTA just like a regular tablet would, as do all of the apps. So they will stay "current" for longer than a factory system would.
