You might want to look into the Alpine Halo series also. It has the latest and greatest with wireless android auto etc, and is certainly expensive, but I have installed with only a single din fascia in my stock bezel, but the result is an 11 inch floating screen. Has been an absolute lifesaver driving around Sydney. The only thing is that the dash air conditioning vents get obscured by the screen (with the 9 inch this is less of an issue and you can adjust the mounting height vertically), note I have the vents directed straight up past the screen anyway. You can also run in your dash cam, front, side and rear cams, USB memory with movies etc on, and even HDMI stuff, like a Chromecast.
I don't have a photo of it with AA open, but my typical experience is about a third of the screen with Spotify on it, and the other two thirds with Google Maps, which I expand to the whole screen as needed. It's actually been a pretty damn amazing system. Next goal is to run in a reversing cam and hook it up to the reverse lamp signal wire, or fuse, so that is comes on when I shift to R.
To my knowledge it has 4 x 50w RMS built in D class amplifier, so I am running Alpine R 6.5" component speakers with tweeters in the rear sound bar, and 5" speakers in custom 3D printed pods in the front dash. Haven't quite done it yet, but the plan is to install a Kicker 500.1 Mono amp to power the Kicker 6.75" 4 ohm sub in the console. Tbh at the moment I have no sub and it's still pretty nice to listen to.
