She wanted to use her iPod without using the FM Modulator. The newer Sony units have the aux jack in the front which is very nice. I actually like her headunit a lot. Her new one was only $100, great sound. Can't beat it. I like my bidget beater JVC too. Mine was $140 new, but it plays mp3 data cds which was new when I bought it, so I feel like I got a good deal too.
