For what it's worth, I have a Sony... XT-XM1, I think... and the CD does skip, even on slightly-rough suburban roads. Also the front panel doesn't seat properly, so the display and controls are a bit "iffy". Good sound, though, when it's working properly.
It's a great example of "too much radio for a car"... it has three FM and two AM bands, six or more Eq settings, and that's not even getting into the XM stuff.
Then it has a display that, when the radio's dormant, flashes messages about all the features -- just what you need at night -- and I haven't yet figured out how to blank it to just the clock, without shutting off the radio entirely. So I just turn the volume to "zero" (assuming the volume control works).
Like I wrote above, though... good sound when it's working right.
