According to the video, we can insert SD card to play the video in the LCD screen. It supports mp4 format. Also it comes with a remote control for LED lightning. But in the video, the guy just mention very little or not much information about the speaker. I guess the main point is not on the speaker for this VF-1 cockpit. Also, it is not a bluetooth speaker and did not mention we can plug-in any external source for music. All rely on SD card? I guess so.
