There is a sign below the screen that tells you the station and you can use any radio app you wish to listen to the movie, there is lots of radio apps
Below the movie screen is a white sign with black letters that shows the radio channel for that particular screen.
Two screens two different radio stations , you get them when you pay to see the movie .
They have two different radio stations, one for each screen. I dot know the number, but they only work when u are close by the area. I dont think the drive in have an app but you could try to download a radio station and tune up the number, as I said it only works when you are in the aream
