Car karaoke system for vehicles. Used once. It should be easy to use, just match the frequency with FM, but I couldn't use it because I'm not good with machines, so I'm selling it. You can use karaoke apps, but YouTube is also OK. Stress relief! (*^◯^*) Kids would probably love it (((o(*゜▽゜*)o))) I kept it for about 8 years, thinking I'd use it someday (^_^; For those who understand that it's a used item, thank you! It's on sale! ※The following is from the website※ "Kuruma Uta Maru" is a car karaoke system that connects to smartphones such as iPad, iPhone, and Android, and allows you to sing songs stored on your smartphone or karaoke app songs for iOS/Android in your car using a microphone. It consists of a microphone, a karaoke unit, an FM transmitter, and a cigarette plug. It uses an FM transmitter method that transmits microphone audio and karaoke music via FM radio waves and plays it from the car stereo. It allows you to enjoy karaoke with dynamic sound from the car speakers. The karaoke unit has two microphone input terminals, and you can sing a duet by connecting two microphones to each terminal. You can adjust the echo amount and the input volume from the microphone steplessly by turning the dial on the karaoke unit.
