Hey there,

I also encounter the screech, but only when switching from tape to CD. No problem with text.

I do have a different problem though. Over the past few days the DICE cable has been unable to charge my iPhone 3G. It did charge in the past. The music and control elements still work, but no charge.

I disconnected the DICE for a few minutes, and that got it to charge once. It stopped working again after shutting off the car.

I don't know if it matters, but I consistently get the "Not a supported accessory" error when connecting the unit. Always have.
