Thanks Phil.
Good info - assuming there's *no* electrolytic caps inside that tend to dry out & fail *over time* when hot. There's some folks with heat related screen issues over time in hotter areas than Viginia (like Florida, Aridzona) - solution to tint windshield/also sun shade when parked: https://teslamotorsclub.com/tmc/threads/unresponsive-screen-in-the-heat.273151/ Looks like Tesla did what they usually do, try & fix it in a "free" software update (although this appears to be a different issue than sun overheating): https://driveteslacanada.ca/news/tesla-recall-overheating-infotainment-display/ Last year I went through a similar issue with my older (M series) Enphase solar microinverters (mounted 1" from the back of solar panels) that some were dying in our new 100F+ (37.7C) heat (since global warming has become popular), found that the caps were cooking - since the inverters were mounted flat behind the solar panels, running about 100C. Mounting them sideways (perpendicular to the panels) lowered their temp 20F and stopped the failures. Anyway, just thinking for longevity - I should figure out how to make the screen run cooler.

Test it in the shade and you'll see it barely gets warm. There is no danger from letting it get hot, again on your car there is no computer in there, it's just a screen. The computer is behind the glovebox on the firewall and it's liquid-cooled.

I thought of Epoxying a big finned heat sink on the back.
