I wanted to use it for the car radio. Unfortunately I didn't find out enough about this stick, it only works on pc's or similar where you can insert a small installation CD... Devinitiv my mistake.🙄 Is there a bluetooth usb stick, or mobile - to - stick - to car radio. That works with simple car radios? So without having to install anything? Just for listening to music. Without a phone or other gimmicks... Thanks for the answers.
