I've been thinking about finding something to replace my stock unit too. I had been thinking dd because I'd like to get ipod interface, dvd, and nav all in one. oh and back up camera! so dd would be the way to go but the couple i looked at on crutchfield's site say they don't fit our trucks. I'd liek to check out the thread on the cover plate that was mentioned. i haven't searched yet but i'll let you all know if i find it before anyone else points us in the right direction!
