My car radio has full iPod integration.... I connect a cable- I can view my playlists and such all through the radio. The problem is, when I return to re-sync my iPod, it doesn't register anything played. I'm guessing that it's because the songs weren't actually played via the iPod- but it would be nice if they updated on iTunes... since it does update the iPod (at least until I re-sync and it loses them). Ideas? or is it a lost cause?
