Car karaoke system for vehicles. Used once. It should be easy to use, just match the frequency with FM, but I couldn't figure it out since I'm not good with machines, so I'm selling it. You'll need a karaoke app, but YouTube also works. 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 it's a used item, thank you! It's priced low! ※The following is from the website※ "Kuruma Uta Maru" connects to smartphones like iPad, iPhone, and Android, allowing you to sing along in your car using a microphone with songs stored on your phone or karaoke apps for iOS/Android. It consists of a microphone, karaoke unit, FM transmitter, and a cigarette lighter plug. It uses an FM transmitter method, broadcasting the microphone audio and karaoke music via FM radio waves, which are then played through the car stereo. This allows you to enjoy karaoke with dynamic sound from your car speakers. The karaoke unit has two microphone input jacks, allowing for duets when two microphones are connected. You can adjust the echo amount and microphone input volume steplessly by turning the dial on the karaoke unit.
