How to play videos and music from android s7 active to my boss b9976b flip screen

When i plug the phone to the usb port on my b9976b boss tilt screen radio it just pulls up the loading screen on the radio and ive sat for half an hour waiting but nothing. I havent tried an auxiliary cord before because i assume they only play music and not videos. When using bluetooth it will on play the music but not stream the video.. Any help and recommendations would be greatly appreciated

Welcome to Android Central! According to the information on the Amazon page, the USB port is only for USB flash drives, not to connect to a smartphone. It's doubtful that you can play videos from your phone to the screen, because for that to work, the phone would have to support an MHL adapter, and it doesn't: MHL® – Devices
