I received this as a gift, but I'm not going to use it, so I'm selling it. I've confirmed that it works. (It was used for about 2-3 days.) This is an FM transmitter KD-254 with Bluetooth functionality, convenient for connecting to a cigarette lighter socket. - Model: KD-254 - Bluetooth Function: Yes - Included Items: Instruction manual - Power Connection: Cigarette lighter socket
