Can anyone explain how this actually works? I can't tell if it is JUST the screen, or if it has the box too (I think maybe head unit? sorry not fully understanding what things are called).

I see this product has several configurations, and this is where I get even more confused. It advertises Android 14, what exactly does that mean? Is it only compatible with Android 14? My Samsung S23u is Android 15 and typically products (unless they are really old ) will connect with most versions of Android. I also see other versions of this screen advertised as Android 11, 12 or 13. Does that mean they won't connect to other versions of Android?

I added 3 photos below. Im wondering what the 4+32GB means.. Im guessing 4gb ram and 32gb of storage? If this is the case, is the storage for music (mp3) or movies (mp4). If that is true, I understand but if this is connected to my phone, wouldn't I just be playing the mp3 and mp4 from my phones storage?

The 2nd product screenshot looks the same but adds a DVR, is that for recording the rear camera, or what would it be saving on DVR?

The 3rd product screenshot adds 8core and adds 360 camera as well as a flash drive. Could the 360 camera be installed on my 2017 F55? Is that just a front camera and a rear camera and the software figures out the rest of the 360? What would the flash drive be for?

The 4th screenshot is my current 6.5" screen.

For clarification, I have a 2017 Mini Cooper S Hardtop 4door F55. It has the newer NBT (I think) screen in it now, looks like 6.5". I mainly want to add backup camera and Android Auto but if I can get a bigger screen as well that would be awesome. I just don't want to buy this and discover I need to buy something else to make it work. Likely I can't return it to China.

If you are interested, this link will show you all the models but starts at the base model (the 1st screenshot)

Thanks in advance if anyone is able to help!
