At times I hear a bell ringing, when it rings, it would stop the radio, cd, ipod, etc and the bell would ring for a short while. At first, it thought it came from an ipod song, but then I heard it and the ipod wasn't connected.
I wonder if it has anything to do with switching the switch at the bottom of the unit so that I can play dvd's while I drive. I wanted to call Pioneer, but I was afraid that they may tell me that it's because of that switch and that I voided the warranty.
Thanks
