My 2023 still doesn't do AA wired split screen 😑 it's the 2/3 screen. Tried every setting possible.Android Auto is full screen but AA does split 2 apps (both are AA apps). If you want 1 app, yes, you need the AAWireless in order to alter the DPI to trick it to one app. However, the DPI being raised also makes everything bigger. I didn't mind it at first, but it bothered me after a time. I've since lowered my DPI to about 190 which shrinks things even further than the factory default but does in enforce the 2 apps on the AAuto split view. I do use Spotify with maps, so I'm not bothered too much by it.
