That was what I was planning to get actually, it was definitely my first choice. Then I read the manual, and confirmed with Kenwood Support, that the right wheel button works in a backwoods manner...and one that I find totally F'ing annoying and unusable.
See, instead of making the right wheel button work properly, where turning it clockwise/counterclockwise moves you up and down the AM/FM band or up and down the tracks in folder you're in....instead they make you have to push the right wheel button left/right. If you happen to accidentally rotate the wheel when you're trying to push it...sorry, now you're into a menu instead of doing what you wanted to do.
Now, when it's mounted on the wall that works just fine....mounted in your car, in traffic, driving, well....for either my brother or I, it's just not a pleasure to use at all; and we both know this as he has a KDC-X891...same control setup.
After the idiocy that is his -X891 right wheel control, I swore off that type of setup forever. I prefer the left+right wheel decks...but, only when the right wheel works properly.
You can't imagine my disappointment when I found that the KDC-X993 was setup like that... //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
