07 has a better stereo. lol. Just kidding. It does seem to have more output then the 06, but other then that there's no difference. I seem to have a rattle problem on both however. The 06 something rattled and now on this one something rattles, two things actually. Something in the glove box area on occasion and something in the back window area. I can't find either for the life of me. Almost wonder if I have an older truck. lol.
