The tape cassette player is original. We couldn't open it. Radio Bi is working Bi is going. So he gets stuck on his head.. Electricity is coming. Exit mute is written on the display, trying to turn up the volume by pressing the volume up button, no response. Inscriptions including the name of the radios are coming, the time and date part is coming, but the radio is not turned on.. What do you think I should do.. Also, can another tape recorder with Android compatible screen be attached to this vehicle.
