So you have your iPod and it works great, except when it comes to listening in your car. Maybe you picked up an FM modulator and that works somewhat well, except in large cities where it is almost impossible to get a clear station. If your car still has a tape deck maybe you have a mini-jack to tape adapter, which actually works fairly decently especially for 20 or so dollars it costs. Unfortunately if with both of those methods a point comes when the iPod runs out of juice and you have to charge it. Also both of those methods require access to the iPod to control your music selection. The Dension iceLink solves all of these problems.
