yeah, thats what i dislike about it too!i was a little disappointed with the ergonomics of the kenwood decks, kind of a hassle to use, but they have some cool features.
the 789 has phatnoise too,the ergonomics of every HU is messed up not just kenwood,every japanese designed HU I have seen in the last 10 years is a cluster fvck of motion,they keep on cramming features into these little boxes and never ever test them out on the US buyers before they go into production and we all end up fustrated and confused,once you get the hang of the Kenwoods they are still easier than the Alpines,but not as easy as the Pio's and not even neer as tough as the Eclipse's(talk about a clusterfvck)the main diff between the two is that the 889 comes with the phatnoise mp3 software, and i believe it has a better DAC. iirc the 789 is the standard DAC, for the 24bit one you need the 889. the mp3 software is kinda cool if you listen to mp3's.
