I'm wanting to hook up my zune to my wifes 03 xterra, and I think I'm on the right track, but just looking for some more info. She has a factory stereo, and her truck is the bottom of the line...like manual windows/locks, bare minimum. I found some wired FM modulators that could work http://www.crutchfield.com/App/Product/Item/Main.aspx?i=142FMMOD01&tp=1287&tab=review being one of the better ones. But I'm also checking out these aux input converters/P.I.E. units which seem to be a little better, but a little more expensive. They also require a cd changer aux port. Does anybody have any experiece with these, or should I just say fuck it and spend the extra cash and get a cheap radio with an aux port on the front? http://www.bestbuy.com/site/olspage.jsp?skuId=8629406&type=product&id=1194051280982 any info will be greatful. We aren't about spending a shit load of cash, and it doesn't have to be a super professional system. Just something simple and effective is fine.
