Some folks posted their A/V systems failed to work properly after the car was parked in the sun a while - especially if the passenger side was facing the sun. That is evidence in support of the heat theory.
Others though have had unresponsive A/V systems first thing in the morning, even when the car was parked in a garage for the night. Heat should not have been a factor there. Those A/V systems worked fine after being shut off 20+ minutes in the sun.
My car has (yet) to do the total A/V unresponsive thing though XM once in a while goes stupid - as if my subscription was canceled while I was listening. I suddenly can't tune any channel not in the preset/memories - it just tunes to channel 0. The various text lines on the Nav display disappear when this happens, then recover a moment later. This seems to happen 10 to 20 minutes after starting the car; both in mornings on the way to work after being parked in the garage all night and after sitting in the sun all day at work. It did it for a few weeks in a row, pretty much every time I drove the car (I have multiple cars so the Genesis doesn't see daily use). Lately though it hasn't happened... and I remember it happening a while ago, maybe a year ago. The XM provider doing something funky on a yearly basis? Dunno.
For most folks with Tech package A/V systems "going stupid" the fix seems to be a NEW (not remanufactured) amp unit since that also has the XM receiver. And not letting XM expire... certain problems seem to be more prevalent for folks that don't have XM subscriptions. (slow A/V start-ups, voice recognition locking up the system, etc)
Heat can and does cause electronic systems to not work properly... and it can cause "accumulated" damage to certain electronic components too. Such damage though would tend to be steadily increasing (electronic parts generally don't "heal" on their own) making the A/V system more and more flaky. Yet most A/V start-up failures seem totally random - it may go for weeks or months without a problem and then one day it just won't wake up properly... 20 minutes later it's fine again and may go a while without problems.
The symptoms I've seen on this forum are more like a PC that has problems booting once in a while - for no apparent reason, some PCs just don't start once in a while. Cycle the power switch and it boots normally on the second try. The Tech A/V system doesn't shut off immediately - it goes to a "standby" mode for about 20 minutes in case you're just running into 7-11 or whatever, that way it can re-start quickly. After 20 minutes of standby it fully shuts off. So it takes 20+ minutes to "cycle the power switch" on Tech A/V systems. Typical asynchronous software hiccups... kinda like when you split a big job between several folks "I'll do this piece, Joe you do that one, Fred you do something else, Hank when you get your piece done give it to Joe 'cause he'll need it for part of his piece; when we're all done we'll meet here with the results." If anybody has a problem with their piece of the job, the whole gang fails.

Just picked up a 2011 4.6 fully loaded demo with 5K. The speakers cut out on a regular basis. I would first guess that its the amp, but the dealer plans to replace the radio. Glad I leased!
