Got my sis an iPod shuffle for Christmas ... (ha ... she will love it, but she is SO techno behind ...!)I think she has a CD/tape system in her car. I know there are conversion sets out there.1. Will a Shuffle hook up to a car system? Particularly for the SHUFFLE2. Where do I purchase a conversion set ... I had a conversion tape that connected to my iPod and then I would insert into the tape player of my car.Your suggestions or directions as to where I can find something like this?Thanks so much!
