Sorry for delay. 13". Connected to play audio through the factory radio or through dual wireless headphones. Plays DVD, can hook up firestick/Roku/chromecast, also have HDMI input wired to the center console box. I can plug iPad or iPhone into that hdmi input and stream content back to the kids. Can also hook up a game console with the rca inputs. Thinking about getting an old PlayStation or maybe even an old Nintendo for some retro games for the kids
