Cd's very hot to touch
 

In my 2009 G37S after listening to a cd only once and ejecting it I find it to be very hot to the touch. I've never experienced a cd being this hot in cars I've owned in the past. With this kind of heat being generated in the audio system I don't expect the system to last very long. I suppose summer heat will make things even worse.

if they start to melt...let us know. :)

yes the cd's get hot but it's totally fine. the touch screen is what is generating all the heat b/c it sits right on top of the cd player. its not going to fail or anything like that, dont worry

That's an interesting opinion about the touch screen generating the heat. I was under the impression that the touch screen was lcd based which is considered to be a very cool running system. Perhaps it's the hard drive that's creating a lot of heat. Excessive heat is the enemy of all things electronic and will definitely reduce the expected lifespan of the audio system no matter where the heat is coming from. But that's just my opinion.
I think I'll start on inventing a water cooled audio system for the Infiniti.

yeah my bad I meant to say the hard drive...not the screen itself. yeah it definitely will shorten the life, but I sincerely doubt that will be less than the life of the car (IMO)

if you come up with one I'll be your first customer :D
