I got the DEH-690UB, the premier one. I LOVE IT! USB input is awesome, cause I bought a 8 GB USB hard drive for $40 and put ALL my Cd's on it. Can't tell you how nice it is to have ALL my music at my fingertips WITHOUT CD's!! YAY BABY!I just got a DEH-P6900UB of course there aren't any installation kits available yet, so it sits in my house.
It has USB as well
