Great little product and seems to be designed well. I bought a knock off on e-bay and then found out that it was not the same. Don't buy a knock off spend the extra money to buy the real thing. You can even go to e-bay and get it for about $40.00.
It also has great reception and nice radio features. Radio works well, easy to use, reasonable price and has good reception. Also comes with a set of earbuds.
All you have to do is plug this baby in and you get a radio option on the main menu. When in radio mode you can set station presets easily and if the station you are listening to supports RDS you will see the song information displayed.
There are a couple minor complaints with it worth mentioning. First you cannot charge your ipod while listening to the radio as the radio plugs into the dock connector. Second, it really drains battery life. I haven't done any formal testing but my non-scientific observation would put battery drain at 2x or greater of normal music listening usage .
