It's against the law and also against common sense, to wear headphones or ear buds when you drive. But there is an easy way to solve this problem. This little gadget will let you listen to your MP3 player's music and podcasts in the car. It works like a dream with almost all the different types of MP3 players, cassette players, and even CD players.

The Griffin iTrip Auto Universal Plus is an FM transmitter for your car. You simply plug one end into the cigarette lighter on your car and the other into your MP3 player.You press the SmartScan button and the device will find an unused FM station to transmit over. Tune your car radio to that frequency and you will hear your music and podcasts over the car speakers.

While most other FM transmitters are device-specific, this little dandy can be used with iPods as well as with most other MP3 players. It even lets you charge your player while your drive.
