OT: Many moons ago, I had one of those cheap Belkin 3.5 mm –> FM car adapters (my car didn't have bluetooth in any form, this was like 2003, but it made it possible to use my iPod instead of the car's cassette player). Anyway, frequency selection was a manual process, and while the best sound quality was found on frequencies where no radio stations transmitted, it was fully possible to dial in an already occupied frequency. Power output was low, but strong enough to overpower anything in a 10-15 m radius, forcing nearby cars in a traffic jam to listen to my music.
