I understand what you're all saying, but perhaps (just maybe) you guys are mistaken. Let me explain. That's obviously not the factory-installed dash that the car came with. So my theory is that the black plastic thing was used to convert the double din opening into a single one, so that the single din dash could be mounted. Perhaps (just maybe) this adapter is making you guys think that it is not double din. I don't know.. just thinking out loud.
I went out and measured the opening, sans the black adapter thing, and it measured to be 4in. Then I measured the opening, counting the black adapter thing, and it measured to be about 3.5in. So if a double din dash doesn't need a similar black adapter thing for mounting, then one should fit, but if it does need something like that, then I can see that it wouldn't fit.
But who knows. Like I said before, I'm car-illiterate. lol
