As was posted above, this "phenomenon" does occur, but it seems YMMV based on the responses of several X7 owners. My windshield is tinted 70%, my two front side windows are tinted 40%, and my sunroof is tinted 70% - all 3M Crystaline tint to help with heat rejection. I have not experienced any significant or noteworthy dimming of my dash during the day. What slight dimming I did finally notice I would never have noticed if I were not specifically looking for it (as a result of people posting this issue on the forums). But I can "manually" make my dash dim by putting my hand over the sensor so this issue is clearly something. But it is hard to pin down exactly what are the optimum conditions and/or items (like type of tint) that is causing it given the varying reports of its occurrence.
