Naxa NA-3030 MP3/WMA FM Modulator/Transmitter with LCD Screen, USB &amp; SD Inputs &amp; Built-In 4GB Flash Memory
The transmitter is OK for the price you paid. It has internal memory to hold good number of songs. I use it everyday. Copying songs is easy. Only thing is the remote is not very responsive and need few trials to get one thing done. But again, looking at the price, I think this can be manageable.
