No it is always about one second after changing tracks and last for about half of one second. The audio fades out and then back again, it probably never goes to 100% muted, you would not hear it on a track with a second or two of silence at the start.

Using the DIP switches to disable text clears the problem, turning off text via the CD6 'routing' function does not. I also tried routing the text to all of the different options without sucess.

For whateven reason it always occurs when switching tracks with the steering wheel controls though as I mentioned it may not occur if I use the Ipod controls. At first I thought it had to do with ID3 tag length but I have seen it happen on tracks without tags.

The Ipod is a video unit with the latest firmware, the Dice link is only a few weeks old. The car also has BMW assist fitted but not enabled if that makes a difference?

DiceLink had me try a different option using the car dip switches but as far as I can tell it has no effect.

Other than that the unit works as described.
