Yeah, Pioneer does make some bad ass head units. The one you have, DEH-P6400 is the same as the one I suggested and have other than it being an mp3 player, a few more added functions to tinker with sound quality, and two of the bottom buttons are blue where they're green on the 6400 series. BUt overall, they are excellent head units and better than any other in my opinion cause of all the functions they come with to make the sound quality just how you want it. Plus they have backgrounds and screensavers, hehe. :thumbup:
