T-Mobile MyTouch 3.5mm Power Play FM Transmitter & Car Charger
Product Review (submitted on September 24, 2011):
I have one of these for my car and I am ordering another for my second car as it is a wonderful product that allows me not only to listen to my own music but to answer the phone and talk totally hands free. There is a USB port which allows you to charge another device while your phone charges. I have been very, very happy with this product.
