Along with the stereo link, I bought the travel pack. The stereo link enables me to listen to my Zune while on the road. No more burning cd's for my car. I am able to create plpaylists on my Zune, so create a playlist of songs I want to listen to while driving. I use it in conjunction with the Zune travel pack. The travel pack comes with a remote that can attach to your clothing so I don't have to reach for the up/down buttons when I want to skip a song. I attached the clip to the seat belt that crosses over mt chest. I am not distracted my taking my eyes off the road. I love my Zune accesories.
