WOW!! There's nothing held back in the design and function of this unit. Fits right in place with the factory brackets. Everything but the kitchen sink in thrown in as far as features. Some will say that a 6 CD stacker would be nice but as long as there is MP3 capabilities a stacker would be almost overkill. But if I had my druthers I'd take the stacker over the cassette feature that is built into the unit. Especially nice is the 13-band(yes, 13) programmable EQ and the virtual theatre settings that this unit can match.
