This is what I'm looking to do. I just got a new car that has a USB port and I am able to plug my ipod in and access all of my music via my stereo controls. I can access my music by my playlists (which is what I almost always do) or by album, artist, etc. This is great and I can actually leave my ipod connected when I turn my car off and when I start it back up it will pick up right where it left off.; however, I have concerns about leaving an ipod in my car all the time. I'm not so concerned about theft since the ipod is hidden away in the center console. What I am concerned about though is temperature extremes and how they will affect my ipod. I figure that a flash drive is much cheaper and not as sensitive to temperature but I don't know if I will be able to access my music the same way on a flash drive. Is there any easy way for me to duplicate my itunes library on a flash drive? I'm only interested in audio files of course but I want all my playlists to remain intact and I'd like to still be able to access my music by artist, album, etc. Basically I want the flash drive to mimic an ipod as far as how I can access it from my car stereo. Is this possible?
