I fitted a flip-out 8" Android touch screen stereo, in a previous vehicle. It was a Single DIN unit.
You do have to observe the location you want to install it to, as once that screen flips out and sits up vertically, it WILL partially cover up the controls / dials / air vents, that are positioned above the Stereo in your centre console.

Being an Android unit you weren't limited to the pre-installed features. You had access on the Stereo to the Android APP Store and could download a replacement DAB Player, or GPS App, or anything else you wanted.
I did also it hooked up to a rear / reverse camera. Along with OBD2, DAB, worked nicely.

Can pickup something like this on EBay cheaper than the premium brand options. Most are "generic" chinese units. Better ones branded as Joying, Pumpkin, etc...
