Android Auto Wallpapers

Just noticed that the long-promised AA wallpapers are active on my phones. The settings are within the "Settings" app in the head unit, not the AA settings in the phones themselves. In fact there is no indication within the individual phones that the new wallpapers even exist (at least I haven't found one).

There are 12 pretty nice choices, but no provision to set a custom image. Also the wallpaper chosen pertains to a particular phone and not the vehicle, even thought the settings are in the vehicle, and not in the phones. Odd? Yes!
Her's a quick snap of the result.
