      Early troubles


      from Florida

      Comments about Sony Marine CD Receiver:

      The boat is not even one year old yet and the stereo is giving me problems. The remote control is the only way to turn it off, adjust the volume, change channels ect. There is no eject button on the remote, so we have a CD stuck in the player. I believe I am still under warranty but if this is a sign of things to come, I may pursue different brands if I have to replace it.
