JVC KD-G720 Car CD / MP3 Player

I was excited to find a stereo with a USB right on the face. I asked my (Fry's) salesperson if I could plug my iPod directly in rather than installing the optional KS-PD100 iPod Adapter - he said "sure." He was right, to a point. You can plug direct, but can't control the iPod at all - not with its own controls or with the head unit (which I knew). It only plays in random order, but the SAME random order every time. So I installed the converter. I have 4700 songs on my iPod. There is nothing more frustrating than trying to scroll through them using arrow buttons that don't fast advance if held down. We're talking one push, one item. The display can't show enough of the song title, artist, or whatever it's trying to show to make any sense. I'm sorely disappointed.
