the box fits so perfect that I didn't have to tie it down at all!! With the trunk protect, I just pushed it up to the back of the seats and it's very snug just as if it were custom made!!!!!! That's why I took a close up pick of the top, it fits right under the carpet part, it's perfect, I couldn't believe it. And YES it bumps, for one 12" WOW! But YES the trunk rattles prob. more than anyother car I've had, but I did the licence plate thing then I just need to find what is rattling in the light part. :bigcry:
If your going to do the whole DVD thing than yeah do it all up

but I'm cool with what I have, I don't do a lot of driving to unfamilar parts so the NAV would be a waste 4 me!!!
