It's a shame the auto start/stop, park assist, etc button cluster is permanently affixed to the panel, because its fairly easy to buy and replace the panel itself with a different trim level that has a patterned or satin finish. That panel is also pretty cheap. I did find some replacement panels/covers around but although they were nice looking, they all seem to be glossy and likely to be almost as big of a problem.
I will probably find a satin finish wrap or even plastidip. Both are completely reversible and the panel is easy to remove. If I am proud of the result I'll post it here (lol). I am also tossing about an idea of getting a satin/flat print removable decal and trimming it to fit the panel to add some individuality to the interior.
EDIT: to clarify, the biggest problem surface that I am worried about is the panel around the shifter knob, the other little trim pieces are small enough/angled enough so that I don't have too much of a problem with the sun reflecting.
