Edit: I was wrong, the graph I saw did not compare the Max11, it was comparing the W11. Looks like Max11 is just a Max10 updated to Android 11, but all three are essentially the same hardware. Nice!
I just got an email from Dasaita saying the head unit I ordered is in a quarantined zone so they offered to send me the Max11 model instead of the Vivid model because it is in another warehouse. From what I see on their website, these are essentially the same device with different software. I did see a graph that showed the Max11 with half the RAM, and a PX5 instead of a PX6, but they said it has a PX6 so I assume it has been updated. If not I'll be disappointed.
I plan on probably installing the Vivid software unless I enjoy the Max, but the Max seems to look a little dated.
