I just got my cd head unit installed in my 01 sentra, and the installation guy left about 1/8 of an inch of space between the bottom of the head unit and the dash (the dashboard stereo adapter) so at night when I turned on my lights I can see into the dash. I asked him about and he said it was just the way the kit and car is designed, and there wasn't much he could do about it:bs:. Personally I think he's full of it. Has any one had any issues with gaps between the head unit and stereo kits on their sentras. I'm going to have everything uninstalled and return all of it. He said it wasn't a lot of space, but I know its going to aggrevate the shit out of me because I was already pissed off about it an hour after it was installed . If I wanted gaps, I would have done it myself. I had this done at best buy if anyone was wondering. It was a christmas gift.
