If you own an iPod, install and sync the iPod as an External Hard Drive through the car's iPod USB adapter. You will then have the ability to select artists, playlists, genres, and view album art work on the car's display and have the total functionality of the iPod. I use an iPod Classic 160GB with my entire iTunes Music Library ripped directly from the CDs as Apple Lossless Audio files. The resulting quality of sound is about the best possible. I have found that if you do not rip directly from the CD the sound is sometimes compromised, often quite noticeably.
