Totally on the same page about the scrolling. Turning that off basically killed the noise for me during playback. That said I still have it when I hit the "next track" button repeatedly on the steering wheel or the headunit. The noise is there even while the headunit readout says cd1-01 the whole time.
Annoying. But miles better than the scrolling noise.
Any other dice owners out there? Can you confirm if you have this issue as well if you listen for it? If it's not ubiquitous maybe it's worth trying to swap out my dice box in the hope of getting a better shielded one. If it is ubiquitous I'll just deal w no scrolling.
