I had been looking for a way to secure my portable XM radio in my car when I came across one of these. This is a nice setup since it is attached to the floor using the front left bolt of the passenger seat. The flexible goose-neck allows you to position the radio or mp3 player so the driver can easily see and adjust the player. Nothing is stuck to your dash or console and it does not take up a cup holder. All this for $25 plus shipping.
