She doesn't care for the faceplate design, from what I can tell.

There have been some discussions on this. The faceplate doesn't look like the glitzy billions-of-buttons designs found on other aftermarket stereos. Some see this as a disadvantage.

However, once you get the thing installed in the car and actually LOOK at the way it integrates into the dash, you realize that it actually fits the style of the car better than any of the other gaudy aftermarket designs. In my Honda, it looks perfectly at home in the dash.
