Yes, if you have the right cables with at least one 3.5mm connector then you should have line out. For Cars, only way to do that is using a traditional tape deck system, or an FM Transmitter that hooks up to MP3, but those do not work well in cities.
Feature to look for...
If you want Overpriced, Overrated and Overly simple..Ipod
If you want Affordable, Feature Packed and Simple yet with more complicated features still easily accesible...Creative Zen Micro.
