My car didn't have an aux input button for my sirius reciever so I bought one of these things.http://www.bestbuy.com/site/olspage.jsp ... 2650467219
If you hook it into your ipod you can browse folders and shit with the factory radio. Its the only one I've ever used and it worked well the whole 2 times I used it for the ipod. It is a bit pricey though if you have other options. For me I needed to add the AUX plug and the cheapest I found online was $100. The extra $50 for this thingy which allows up to 3 devices, plus use of the ipod if I want, was worth it to me.
- Oh, great. You killed the invisible swordsman!
-- He's dead, all right.
--- How was I supposed to know where he was?
- You were supposed to fire up. _We_ both fired _up_.
