The iBreath With FM Transmitter
The iBreath's primary function is to serve as a breathalyzer, but it doubles as an FM transmitter for playing your iPod through a car radio. These two functions do not make a harmonious marriage, unless the FM transmitter disables your car when you're over the legal limit.
