My card gets pretty warm. I'm sure things like whether it's in the shade or sun, if it's hot and sunny or not, etc. will contribute. After all, it's against the windshield in a dark, contained area.
That said, I pulled out the USB drive with all my music from below the radio the other day and it was screaming hot! That was a surprise to me.
