I love it. My parents Acadia has a HUD and it's great. Im just as much of a man driving with it as I am without it BTW...
I have to replace my windshield anyway, (which I am told is a requirement to retrofit this into the 2010) So I've got that part taken care of. I just hope the HUD unit itself is not too expensive. I look forward to having this. It would be cool if you could change the color of it too.
