Making a long story short, the 2007 Camry and likely other Toyota vehicles have a poorly designed shuffle algorithm that barely could be called a shuffle at all. Its the sort of thing I'd expect a first semester Computer Science student to turn in and hope the instructor doesn't play with long enough to find how poorly designed it was. Basically, if you insert a CD, it creates 8 playlists from the CD, and never veers from it. When you turn on the car, it always goes to the beginning of the next playlist after the current song finishes. I tried newer model years and saw deja vu, although the issue isn't as pronounced if it still exists on newer vehicles. Please see the youtube video for a demonstration and for a longer description of how it works. Sound is completely unnecessary, just watch the song number.
After some phone calls, seeing a dealership, and frustration, I'm throwing in the towel for getting this fixed and decided just to embarrass Toyota instead by putting up a video. Enjoy. Maybe they'll fix it now if it gets enough attention.
