Sound quality and level of control.

CD skips over bumps. Ergonomics. Display not bright enough. Text too small to read comfortably.

Not an entirely bad product, but could definitely use some refinement. The sound quality on this unit will probably be unmatched since not too many head units have 3 auto-calibrating 27-band equalizers. However, for $700 (MSRP), you would think your CDs would not skip when you go over a bump. You would also think the display would be bright enough to be seen when the sun is shining on it. Then there are the ergonomics, which leave much to be desired. For example, they make you hold a button down for 2 seconds just to access the sound menu. Wanna turn the unit off? Hold the power button down for 2 seconds!
