User Review: I've used this cassette adaptor with my Nano in two different vehicles, and it works great. The sound quality is very close to CD; on some tracks it's indistinguishable.

Yes, you will have a cord connecting your iPod to the cassette player, but I have tried several FM transmittors and I can tell you that this unit, at 1/4th to 1/10th the price of a transmittor, will give you better quality sound. (I loved the concept of wireless FM transmission, but I've yet to find a product that gives even 80% of CD quality sound. There is almost always some level of static interference with FM adaptors, and some loss of fullness to the sound). Given the price, you should at least try this adaptor if you have a cassette player in your car and want to use your iPod.

I'm not sure about the problems others have reported with the tape ejecting or making noise, but I haven't had any problems. Those issues could be related to the cassette player itself...

Obviously, the IDEAL solution to listening to your iPod in the car is to have a car stereo system with an input jack to plug directly into...
