Sony CDX-C680 CD Changer

I just swapped out my Clarion for the new Sony and boy are my ears hurting...i think its from the lack of sound quality. The features offered are neat but how do you get them to work? The world may never know. The buttons are too small to use while driving and forget using the clunky wired remote, it just gets tangled in everything. For the most part the problem is too many features and too few buttons. I'll be putting my sony on ebay and going back w/ my clarion (6475) just because it has the same features and the remote is wireless and the display is much easier to see from an angle, i can't squat down and read the time!
