There seems to be a bit of debate over whether this device works well or not. I can't vouch for every car and radio make there is, but I have tried it in two Hondas (old and new) a Mercedes, a Volvo, and a Subaru, as well as on my home stereo (Panasonic) and if you hold it at just the right angle, within 5 feet of the radio, and don't jiggle it too much, you can get it to work pretty well. However, if you don't like to drive with your knees while balancing your ipod to get proper reception, it just doesn't work that well. Staticky interludes will drive you nuts and so will the fact that there are other devices that don't have these problems. Try something else.
