If you do not know what this is this is a Bluetooth receiver. My car does not have Bluetooth so I can plug this into my auxiliary port and it will play through my car speakers. I have had one for over three years now. I love it! This is how I listen to all my car reads. Well Wednesday night mine was involved in a minor accident where someone accidentally pulled it out of the jack. But this time unlike others it broke. I think I had the same face a small child has when they lose their security toy or blanket. But have no fear thanks to Amazon my new one will be arriving today. Of course it was a little hard listening to my audiobook the last two days but I managed. My drive in Monday should be back to normal listening.
