This system looks a lot like what I experienced on a new Buick, and if so is MUCH, MUCH better than what comes with the Genny. Although i love my Genesis otherwise (especially the smart cruise) I will not buy another one unless the display system is improved significantly.
The Hyundai system (Tech package) also has brightness adjustability, but the sun shining on it just renders it useless. My portable Garmin system has no issues.
I have shielded the screen by putting my hand above the screen and then it's fine. Just not practical, of course

I've noticed Honda has installed a sun shield above their dash mounted GPS units. Pitiful that Hyundai doesn't do something about this problem. *sigh*
