My car needs to be iddeling if I'm going to spend a long time using the radio if not I won't turn on again it's really old. What are other ways I can listen to the movie in my car? Maybe a handheld radio(wakie talkie like type)?

Lio C. What app should I download?

Download radio app to your phone ☺ and get Bluetooth speaker

I have used a portable AM/FM radio. Battery operated Sony Walkman and headphones

Anything that tunes to FM radio will work.
